I am trying to implement font-awesome-picker to a website that i am making using vue2/php/mysql, but within standard js scripting, so no imports, .vue etc.
The script i am trying to add is taken from here: https://github.com/laistomazz/font-awesome-picker
The problem that i am facing is that i have 3 columns that have a title and an icon picker next it, that will allow the user to select 1 icon for each title. It is kinda working well...but if the same icon is used in 2 different columns then any time the user clicks again any of the 2 icons both instances of the picker will fire up, thus showing 2 popups. I need to somehow make them unique.
I've tried using
:key="list.id"
or
v-for="icon in icons" :icon:icon :key="icon"
but nothing worked. Somehow i have to separate all the instances (i think) so they are unique.
This is the template code:
Vue.component('font-awesome-picker', {
template: ' <div><div class="iconPicker__header"><input type="text" class="form-control" :placeholder="searchPlaceholder" #keyup="filterIcons($event)" #blur="resetNew" #keydown.esc="resetNew"></div><div class="iconPicker__body"><div class="iconPicker__icons"><i :class="\'fa \'+icon"></i></div></div></div>',
name: 'fontAwesomePicker',
props: ['seachbox','parentdata'],
data () {
return {
selected: '',
icons,
listobj: {
type: Object
}
};
},
computed: {
searchPlaceholder () {
return this.seachbox || 'search box';
},
},
methods: {
resetNew () {
vm.addNewTo = null;
},
getIcon (icon) {
this.selected = icon;
this.getContent(this.selected);
},
getContent (icon) {
const iconContent = window
.getComputedStyle(document.querySelector(`.fa.${icon}`), ':before')
.getPropertyValue('content');
this.convert(iconContent);
},
convert (value) {
const newValue = value
.charCodeAt(1)
.toString(10)
.replace(/\D/g, '');
let hexValue = Number(newValue).toString(16);
while (hexValue.length < 4) {
hexValue = `0${hexValue}`;
}
this.selecticon(hexValue.toUpperCase());
},
selecticon (value) {
this.listobj = this.$props.parentdata;
const result = {
className: this.selected,
cssValue: value,
listobj: this.listobj
};
this.$emit('selecticon', result);
},
filterIcons (event) {
const search = event.target.value.trim();
let filter = [];
if (search.length > 3) {
filter = icons.filter((item) => {
const regex = new RegExp(search, 'gi');
return item.match(regex);
});
}else{
this.icons = icons;
}
if (filter.length > 0) {
this.icons = filter;
}
}
},
});
I've setup a fiddle with the problem here:
https://jsfiddle.net/3yxk1ahb/1/
Just pick the same icon in both cases, and then click any of the icons again. You'll see that the popups opens for both columns.
How can i separate the pickers ?
problem is in your #click and v-show
you should use list.id instead of list.icon (i.e #click="addNewTo = list.id")

I'm a coop student and I'm working with Highcharts in MVC 4. My employer would like to be able to click on a column on a Column chart and have it take the user to a new page. Does anyone have any ideas on how to do this?
I'm having a hard time finding examples of Highcharts in MVC, so if someone has some good resources please send them my way.
Thanks to the comment and the resource here I was able to solve my own problem. My view takes in a Highcharts object as the model, and when my Controller passes it the following Highcharts object it works:
new Highcharts("chart")
//define the type of chart
.InitChart(new Chart { DefaultSeriesType = ChartTypes.Column})
//overall Title of the chart
.SetTitle(new Title { Text = chartTitle })
//small label below the main Title
.SetSubtitle(new Subtitle { Text = subTitle })
//load the X values
.SetXAxis(new XAxis { Categories = xAxisData })
//set the Y title
.SetYAxis(new YAxis { Title = new YAxisTitle { Text = yAxisTitle } })
.SetTooltip(new Tooltip
{
Enabled = true,
Formatter = #"function() { return '<b>'+ this.series.name +'</b><br/>'+ this.x +': '+ this.y; }"
})
.SetPlotOptions(new PlotOptions
{
Line = new PlotOptionsLine
{
DataLabels = new PlotOptionsLineDataLabels
{
// this makes the value of the dot appear above it if it is set to true (for Line charts)
Enabled = true
},
// set to true so that when the user hovers their mouse over a column/dot it's value and name will appear
EnableMouseTracking = true
},
/***********
* IMPORTANT PART
************/
Series = new PlotOptionsSeries
{
Point = new PlotOptionsSeriesPoint
{
Events = new PlotOptionsSeriesPointEvents
{
// Here you can put code for different event handlers (like Click and MouseOver) in javaScript.
// The one below makes an alert box pop up with the name of the column and its value when a
// column is clicked
Click = "function () {alert('Category: ' + this.category + ', value: ' + this.y);}"
}
}
}
})
//load the Y values
.SetSeries(yAxisData.ToArray());
Defaulty in the highcharts you should catch click event on serie's point.
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function () {
alert('Category: ' + this.category + ', value: ' + this.y);
}
}
}
}
},
Check that wrappers for asp.net supports that option.
I am using JqPlot to display some graph legends on the jqplotMouseEnter, and jqplotMouseLeave events.
Here is my code:
$('#FinancialsLineGraph').bind('jqplotMouseEnter', function(ev, seriesIndex, pointIndex, data) {
$('#FinancialsLineGraph .jqplot-table-legend').show();
});
$('#FinancialsLineGraph').bind('jqplotMouseLeave', function(ev, seriesIndex, pointIndex, data) {
$('#FinancialsLineGraph .jqplot-table-legend').hide();
});
With this above code, when the cursor is moved over the actual legend inside the graph, the legend 'flickers' and the user cannot use the EnhancedLegendRenderer to shown/hide the corresponding series in the plot.
How can I get this above feature working?
Thanks in advance.
EDIT
Here is my JS plot code.
var plotCogsLineGraph = $.jqplot('FinancialsLineGraph', [[30,31,34,40,45], [34,38,31,42,38]],
{
axes:
{
xaxis:
{
ticks: ['5','4','3','2','1']
},
yaxis:
{
label:'%',
pad: 1.05,
ticks: ['0','15','30','45','60']
}
},
width: 480, height: 270,
legend:{show:true, location: 's', placement: 'insideGrid', renderer: $.jqplot.EnhancedLegendRenderer},
seriesDefaults:
{
rendererOptions: {smooth: true}
},
series:[
{
lineWidth:1,
label:'COGS',
markerOptions: { size:1, style:'dimaond' }
},
{
lineWidth:1,
label:'Wages',
markerOptions: { size: 1, style:"dimaond" }
}
]
}
);
What's actually happening here is that the jqplotMouseLeave event is being raised when you enter the legend, causing it to not be displayed, which then raises the jqplotMouseEnter (when the legend is hidden, you all of a sudden enter the plot), causing it to be shown. Because of this cycle, you get the flickering.
Try changing your 'jqplotMouseLeave handler to this:
$('#FinancialsLineGraph).bind('jqplotMouseLeave', function(ev, seriesIndex, pointIndex, data) {
var top, right, bottom, left;
var legend = $('#FinancialsLineGraph .jqplot-table-legend');
top = legend.offset().top;
left = legend.offset().left;
bottom = top + legend.height();
right = left + legend.width();
if (!(ev.pageX >= left && ev.pageX <= right && ev.pageY >= top && ev.pageY <= bottom)) {
$('#chart1 .jqplot-table-legend').hide();
}
});
What this does is hide the legend only if the mouse cursor location is not contained within the legend's bounding box.
I've successfully integrated both a Flot line graph and an instance of FullCalendar into my site. They are both on separate pages (although the pages are loaded into a div via AJAX).
I've added the Flot Resize plugin and that works perfectly, re-sizing the line graph as expected. However, it seems to cause an error when resizing the calendar.
Even if I load the calendar page first, when I resize the window I get this error in the console (also, the calendar does not resize correctly):
TypeError: 'undefined' is not an object (evaluating 'r.w=o!==c?o:q.width()')
I was struggling to work out where the error was coming from, so I removed the link to the Flot Resize JS and tried again. Of course the line graph does not resize, but when resizing the calendar, it works correctly.
The div containers for the two elements have different names and the resize function is called from within the function to draw the line graph (as required).
I have tried moving the link to the Flot Resize plugin into different places (i.e. above/below the fullCalendar JS, into the template which holds the graph), but all to no avail.
Does anyone have any idea where the conflict might be and how I might solve it??
Thanks very much!
EDIT: It seems that the error is also triggered when loading the line graph (flot) page AFTER the fullcalendar page even without resizing the window.... Now I am very confused!
EDIT 2: The code which draws the line graph. The function is called on pageload and recieves the data from JSON pulled off the server. When the graph is loaded, I still get the error about shutdown() being undefined.
function plotLineGraph(theData){
var myData = theData['data'];
var myEvents = theData['events'];
var myDates = theData['dates'];
var events = new Array();

events.push(

}
);
}

}).appendTo("body").fadeIn(200);
}
var previousPoint = null;
$("#placeholder").bind("plothover", function (event, pos, item) {

previousPoint = item.dataIndex;
$("#tooltip").remove();
var x = item.datapoint[0].toFixed(2),
y = item.datapoint[1].toFixed(2);

EDIT 3:
The calendar is called like this:
function showCalendar() {
var date = new Date();
var d = date.getDate();
var m = date.getMonth();
var y = date.getFullYear();
$('#fullcalendar').fullCalendar({
header: {
left: 'prev',
center: 'title',
right: 'next'
},
clickable: true,
firstDay: 1,
eventSources: [
{
url: '/populate-calendar/{{theProductUuid}}/',
color: 'black',
data: {
text: 'text'
}
}
],
eventClick: function(calEvent, jsEvent, view) {
var startDate = $.fullCalendar.formatDate(calEvent.start, 'yyyy-MM-dd');
var endDate = $.fullCalendar.formatDate(calEvent.end, 'yyyy-MM-dd');
var eventId = calEvent.uuid;
$('#modal-event-title').text(calEvent.title);
$('#edit-event-name').val(calEvent.title);
$('#edit-start-date').val(startDate);
$('#edit-end-date').val(endDate);
$('#edit-event-text').val(calEvent.text);
$('#edit-event-btn').attr('data-uuid', eventId);
$('#modal-edit-event').on('click', '#delete-btn', function(){
deleteCalendarEvent(eventId);
});
$('#modal-edit-event').modal();
},
});
}
The AJAX to load the page containing the flot chart:
function loadDetailedReports(uuid){
$('#product-content').fadeOut('slow', function(){
$('#product-content').empty();
$('#whole-product-sub-nav .active').removeClass('active');
$('#detailed-reports-content').load('/detailed-reports/' + uuid + '/', function(){
$('#detailed-reports-btn').addClass('active');
$('#detailed-reports-content').fadeIn('slow', function(){
if (authorized){
setLocationHash('loadDetailedReports&' + uuid);
getChartData(uuid);
} else {
setLocationHash('');
}
});
});
});
}
And the AJAX to load the page containing the calendar:
function loadCalendar(uuid){
$('#detailed-reports-content').empty().hide();
$('#product-content').fadeOut('slow', function(){
$('#whole-product-sub-nav .active').removeClass('active');
$('#product-content').load('/calendar/' + uuid + '/', function(){
$('#calendar-btn').addClass('active');
$('#product-content').fadeIn('slow', function(){
if (authorized){
setLocationHash('loadCalendar&' + uuid);
} else {
setLocationHash('');
}
showCalendar();
});
});
});
}
The calls to .resize and .shutdown are there because I was under the impression that they are necessary to achieve the resizing function and in response to your earlier comment regarding shutdown...... They're quite possibly n00b errors........?!?!
It looks like this is triggering on line 198 of jquery-resize:
data.w = w !== undefined ? w : elem.width();
This sounds like a race-condition stemming from the way you load different content into the same div. Flot binds the resize event to the chart div, and only un-binds it if the plot is destroyed cleanly.
EDIT: Looking at your code, my first suggestion would be to get rid of the resize and shutdown calls at the end of plotLineGraph. The resize plugin doesn't require any setup; it hooks into Flot to attach automatically to any new plot. So your call to resize is actually to jQuery's resize event trigger, which may be what's causing the error.
EDIT #2: I'm still not clear on your structure, but to generalize: anywhere that you might be getting rid of #placeholder (via emptying its parent or anything like that) you should first call shutdown on the plot object. If you aren't keeping a reference to it, you can do it like this: $("#placeholder").data("plot").shutdown(); but then have to account for the fact that it's undefined prior to the creation of your first plot.
If that still doesn't work, I'd need to see a live (simplified) example to make any further suggestions.
I want a button in column header dropdown menu of grid in extjs4.
so that i can add or delete columns which are linked in database.
Any help will be appreciated...
Thankyou..:)
Couple of months ago I had the same problem. I've managed to solve it by extending Ext.grid.header.Container (I've overrided getMenuItems method). However, recently, I've found another solution which requires less coding: just add menu item manualy after grid widget is created.
I'll post the second solution here:
Ext.create('Ext.grid.Panel', {
// ...
listeners: {
afterrender: function() {
var menu = this.headerCt.getMenu();
menu.add([{
text: 'Custom Item',
handler: function() {
var columnDataIndex = menu.activeHeader.dataIndex;
alert('custom item for column "'+columnDataIndex+'" was pressed');
}
}]);
}
}
});
Here is demo.
UPDATE
Here is demo for ExtJs4.1.
From what I have been seeing, you should avoid the afterrender event.
Context:
The application I am building uses a store with a dynamic model. I want my grid to have a customizable model that is fetched from the server (So I can have customizable columns for my customizable grid).
Since the header wasn't available to be modified (since the store gets reloaded and destroys the existing menu that I modified - using the example above). An alternate solution that has the same effect can be executed as such:
Ext.create('Ext.grid.Panel', {
// ...
initComponent: function () {
// renders the header and header menu
this.callParent(arguments);
// now you have access to the header - set an event on the header itself
this.headerCt.on('menucreate', function (cmp, menu, eOpts) {
this.createHeaderMenu(menu);
}, this);
},
createHeaderMenu: function (menu) {
menu.removeAll();
menu.add([
// { custom item here }
// { custom item here }
// { custom item here }
// { custom item here }
]);
}
});
For people who would like to have not just one "standard" column menu but have an individual columnwise like me, may use the following
initComponent: function ()
{
// renders the header and header menu
this.callParent(arguments);
// now you have access to the header - set an event on the header itself
this.headerCt.on('menucreate', function (cmp, menu, eOpts) {
menu.on('beforeshow', this.showHeaderMenu);
}, this);
},
showHeaderMenu: function (menu, eOpts)
{
//define array to store added compoents in
if(this.myAddedComponents === undefined)
{
this.myAddedComponents = new Array();
}
var columnDataIndex = menu.activeHeader.dataIndex,
customMenuComponents = this.myAddedComponents.length;
//remove components if any added
if(customMenuComponents > 0)
{
for(var i = 0; i < customMenuComponents; i++)
{
menu.remove(this.myAddedComponents[i][0].getItemId());
}
this.myAddedComponents.splice(0, customMenuComponents);
}
//add components by column index
switch(columnDataIndex)
{
case 'xyz': this.myAddedComponents.push(menu.add([{
text: 'Custom Item'}]));
break;
}
}
I took #nobbler's answer an created a plugin for this:
Ext.define('Ext.grid.CustomGridColumnMenu', {
extend: 'Ext.AbstractPlugin',
init: function (component) {
var me = this;
me.customMenuItemsCache = [];
component.headerCt.on('menucreate', function (cmp, menu) {
menu.on('beforeshow', me.showHeaderMenu, me);
}, me);
},
showHeaderMenu: function (menu) {
var me = this;
me.removeCustomMenuItems(menu);
me.addCustomMenuitems(menu);
},
removeCustomMenuItems: function (menu) {
var me = this,
menuItem;
while (menuItem = me.customMenuItemsCache.pop()) {
menu.remove(menuItem.getItemId(), false);
}
},
addCustomMenuitems: function (menu) {
var me = this,
renderedItems;
var menuItems = menu.activeHeader.customMenu || [];
if (menuItems.length > 0) {
if (menu.activeHeader.renderedCustomMenuItems === undefined) {
renderedItems = menu.add(menuItems);
menu.activeHeader.renderedCustomMenuItems = renderedItems;
} else {
renderedItems = menu.activeHeader.renderedCustomMenuItems;
menu.add(renderedItems);
}
Ext.each(renderedItems, function (renderedMenuItem) {
me.customMenuItemsCache.push(renderedMenuItem);
});
}
}
});
This is the way you use it (customMenu in the column config let you define your menu):
Ext.define('MyGrid', {
extend: 'Ext.grid.Panel',
plugins: ['Ext.grid.CustomGridColumnMenu'],
columns: [
{
dataIndex: 'name',
customMenu: [
{
text: 'My menu item',
menu: [
{
text: 'My submenu item'
}
]
}
]
}
]
});
The way this plugin works also solves an issue, that the other implementations ran into. Since the custom menu items are created only once for each column (caching of the already rendered version) it will not forget if it was checked before or not.
