I have been struggling to get a number input to format numbers using vuejs2.
Migrating some view logic from asp.net core 2 to vue and I was using this:
<input asp-for="Model.LoanAmount" value="#(Model.LoanAmount > 0 ? Model.LoanAmount.ToString("N2") : String.Empty)" >
but that required me to reload that view onchange of the input.
I need a way to format number inputs with US format and 2 decimal places, (1,000,000.21) but to display nothing when the model value is zero or empty.
vue-numeric does ALMOST everything, but fails for me when I try to use a placeholder.
<vue-numeric v-model="vm.loanAmount" seperator="," placeholder=" " :precision="2" ></vue-numeric>
I tried using a space for placeholder because it crashes when I use an empty string.
This example displays 0.00 if zero or empty is inputted. I tried playing with the output-type and empty-value props.
I'm not wedded to vue-numeric but it is handy because I don't know of a more convenient solution.
You can achieve the formatting by simply using a computed property with separate getter and setter without the need for other dependencies.
computed: {
formattedValue: {
get: function() {
return this.value;
},
set: function(newValue) {
if (newValue.length > 2) {
newValue = newValue.replace(".", "");
this.value =
newValue.substr(0, newValue.length - 2) +
"." +
newValue.substr(newValue.length - 2);
} else {
this.value = newValue;
}
}
}
}

I only added the decimal separator as an example, you'll have to add the , thousand separator in the setter for your full functionality.
I have a Dojo combobox declaratively created using a standard HTML select. There is an onChange event on a separate textbox that invokes a function to get data from a server via XHR and elements of the response data become new options for the drop down.
I've been trying examples across the internet but nothing so far has worked. This is the code I'm currently trying with no errors. In fact, when I look at the contents of the store after the put, the data is in there.
When I click on the drop down after the data has been set, I get the error "_AutoCompleterMixin.js.uncompressed.js:557 Uncaught TypeError: Cannot read property 'toString' of undefined":
var newOptions = new Array();
for (var i = 0; i < jsonData.length; i++) {
newOptions[i] = { value: jsonData[i].dataID,
label: jsonData[i].dataName,
selected: i == 0};
}
var select = registry.byId("combobox");
select.store.put(newOptions, { overwrite: true });
And also "select.store.data = newOptions;".
And also moving the code around so "select.store.add(option)" is within the loop.
Though the combobox store is being populated in all three cases, I continue get the same error. There are no null values in the data. There are no blank values in the data.
What am I missing? No example anywhere, within the DOJO docs or anywhere else has this problem, even working jsFiddle examples.
I simply cannot see what the difference is other than the fact I'm adding more than one or two hard-coded values.
It takes:
newOptions[i] = { id: jsonData[i].dataID,
name: jsonData[i].dataName,
selected: i == 0};
not
newOptions[i] = { value: jsonData[i].dataID,
label: jsonData[i].dataName,
selected: i == 0};
I want to limit map extent to the initial extent of the map and limit user from panning more than certain extent.
I tried following but nothing has changed:
map = new Map( "map" , {
basemap: "gray",
center: [-85.416, 49.000],
zoom : 6,
logo: false,
sliderStyle: "small"
});
dojo.connect(map, "onExtentChange", function (){
var initExtent = map.extent;
var extent = map.extent.getCenter();
if(initExtent.contains(extent)){}
else{map.setExtent(initExtent)}
});
Just to flesh out Simon's answer somewhat, and give an example. Ideally you need two variables at the same scope as map:
initExtent to store the boundary of your valid extent, and
validExtent to store the last valid extent found while panning, so that you can bounce back to it.
I've used the newer dojo.on event syntax as well for this example, it's probably a good idea to move to this as per the documentation's recommendation - I assume ESRI will discontinue the older style at some point.
var map;
var validExtent;
var initExtent;
[...]
require(['dojo/on'], function(on) {
on(map, 'pan', function(evt) {
if ( !initExtent.contains(evt.extent) ) {
console.log('Outside bounds!');
} else {
console.log('Updated extent');
validExtent = evt.extent;
}
});
on(map, 'pan-end', function(evt) {
if ( !initExtent.contains(evt.extent) ) {
map.setExtent(validExtent);
}
});
});
You can do the same with the zoom events, or use extent-change if you want to trap everything. Up to you.
It looks like your extent changed function is setting the initial extent variable to the maps current extent and then checking if that extent contains the current extents centre point - which of course it always will.
Instead, declare initExtent at the same scope of the map variable. Then, change the on load event to set this global scope variable rather than a local variable. In the extent changed function, don't update the value of initExtent, simply check the initExtent contains the entire of the current extent.
Alternatively you could compare each bound of the current extent to each bound of the initExtent, e.g. is initExtent.xmin < map.extent.xmin and if any are, create a new extent setting any exceeded bounds to the initExtent values.
The only problem is these techniques will allow the initExtent to be exceeded briefly, but will then snap the extent back once the extent changed function fires and catches up.
I originally posted this solution on gis.stackexchange in answer to this question: https://gis.stackexchange.com/a/199366
Here's a code sample from that post:
//This function limits the extent of the map to prevent users from scrolling
//far away from the initial extent.
function limitMapExtent(map) {
var initialExtent = map.extent;
map.on('extent-change', function(event) {
//If the map has moved to the point where it's center is
//outside the initial boundaries, then move it back to the
//edge where it moved out
var currentCenter = map.extent.getCenter();
if (!initialExtent.contains(currentCenter) &&
event.delta.x !== 0 && event.delta.y !== 0) {
var newCenter = map.extent.getCenter();
//check each side of the initial extent and if the
//current center is outside that extent,
//set the new center to be on the edge that it went out on
if (currentCenter.x < initialExtent.xmin) {
newCenter.x = initialExtent.xmin;
}
if (currentCenter.x > initialExtent.xmax) {
newCenter.x = initialExtent.xmax;
}
if (currentCenter.y < initialExtent.ymin) {
newCenter.y = initialExtent.ymin;
}
if (currentCenter.y > initialExtent.ymax) {
newCenter.y = initialExtent.ymax;
}
map.centerAt(newCenter);
}
});
}
And here's a working jsFiddle example: http://jsfiddle.net/sirhcybe/aL1p24xy/
I have a spider plot in using the graphing library of Dojo defined like this:
require([
"dojox/charting/Chart",
"dojox/charting/themes/Claro",
"dojox/charting/plot2d/Spider",
"dojox/charting/action2d/Tooltip",
"dojox/charting/widget/SelectableLegend",
"dojox/charting/axis2d/Default"
], function (Chart, theme, Spider, Tooltip, Legend, Default) {
var chart = new Chart(element).setTheme(theme).addPlot("default", {
type: Spider,
radius: 200,
fontColor: "black",
labelOffset: "-20"
});
var colors = ["blue", "red", "green", "yellow", "purple", "orange", "teal",
"maroon", "olive", "lime", "aqua", "fuchsia"];
$.each(factors, function (index, factor) {
chart.addAxis(factor.name, {
type: Default,
min: factor.min,
max: factor.max
});
});
$.each(presets, function (pIndex, preset) {
var data = [];
$.each(factors, function (fIndex, factor) {
data[factor.name] = preset.values[fIndex];
});
chart.addSeries(preset.short, data, {
fill: colors[pIndex % colors.length]
});
});
new Tooltip(chart, "default");
chart.render();
new Legend({
chart: chart,
horizontal: false
}, $(element).next(".legend")[0]);
});
I add a series for every member of an array called presets and I use a selectable legend that lets the user turn them on or off as they want. However, what I can't seem to find in the docs is how to start a series in the unselected, not visible state? What I ideally want to do is cap the number of series visible when the page loads because in some cases I have up to 14 presets and it just looks a mess until the user deselects a bunch. So I'd like to have, say, every preset above the first 5 be hidden at the start.
Here's a crude fiddle I've knocked to demonstrate. What I want is to have some of the series unselected when the plot is first displayed.
Update: I tried adding this after adding my series:
var checkboxes = $(".dijitCheckBoxInput").each((index, elem) => {
if (index > 4) {
elem.click();
}
});
Which works, but seems very fragile. If they change the class assigned to checkboxes, it'll break. Also, it prohibits me using more than one set of dojo checkboxes because I don't have a good way to tell the difference. (Note, the IDs of the checkboxes added by the SelectableLegend are dijit_form_CheckBox_0, dijit_form_CheckBox_1, etc, which also gives no useful information as to what they are related to). I thought I might be able to use the legend placeholder div as a way to select the descendant checkboxes, but it appears that Dojo replaces the placeholder entirely with a table.
i looked into the dojo code and found the area in which the shapes are toggled on & off whitin the SelectableLegend.js :
var legendCheckBox = query(".dijitCheckBox", legend)[0];
hub.connect(legendCheckBox, "onclick", this, function(e){
this._toggle(shapes, i, legend.vanished, originalDyn, seriesName, plotName);
legend.vanished = !legend.vanished;
e.stopPropagation();
});
The toggling process is very complex and is based on many local attributes:
_toggle: function(shapes, index, isOff, dyn, seriesName, plotName){
arrayUtil.forEach(shapes, function(shape, i){
var startFill = dyn.fills[i],
endFill = this._getTransitionFill(plotName),
startStroke = dyn.strokes[i],
endStroke = this.transitionStroke;
if(startFill){
if(endFill && (typeof startFill == "string" || startFill instanceof Color)){
fx.animateFill({
shape: shape,
color: {
start: isOff ? endFill : startFill,
end: isOff ? startFill : endFill
}
}).play();
}else{
shape.setFill(isOff ? startFill : endFill);
}
}
if(startStroke && !this.outline){
shape.setStroke(isOff ? startStroke : endStroke);
}
}, this);
}
I tried also checking & unchecking the dijit/form/Checkbox in a legend manually, but that does not trigger the _toggle function in any case, even if you do a render() / fullrender() on the chart.
With that in mind it seems that there is no other possibilty to toggle the series on and off than by firing the onclick events manually.
To make your code less fragile, you could access the Checkbox widgets within the legend manually using:
query(".dijitCheckBox", legend); // Should deliver an array containing
the widgets.
and triggering the onclick event on them. Their keynumber in the array should correspond to the order the series where added...
Dojo is a fine piece of work, please dont stop working with it !
dojox/charting/Series has an attribute called dirty which according to the API docs is a "flag indicating whether or not this element needs to be rendered".
Alternately, if you are limiting the display of some series you can write a separate interface for adding them. For example, loop over the first 5. Then create a select box or list of check boxes with all entries and an onchange event that calls chart.addSeries.
Keeping a reference to each series you create will allow you to later call destroy() or destroyRecursive() on it if the user no longer wishes it displayed.
So while ideally you could toggle the display of these series, the worst case senerio is that you just add, destroy, and read based on some user input.
Using a templated widget will allow you to keep this interface and the chart tightly linked and support reuse.
BTW, consider using "dojo/_base/array" and "dojo/query" in place of the jquery
I think i've got it !
I found another way to access the checkboxes ! It's the same way dojo uses internally to connect the "toggle code" to the onclick event. First take a look at this from SelectableLegend.js (Lines 150 - 156):
// toggle action
var legendCheckBox = query(".dijitCheckBox", legend)[0];
hub.connect(legendCheckBox, "onclick", this, function(e){
this._toggle(shapes, i, legend.vanished, originalDyn, seriesName, plotName);
legend.vanished = !legend.vanished;
e.stopPropagation();
});
It looks like they use the ".dijitCheckBox" class to find the checkbox dom element and connect to it using dojo/connect. Now based on that, i made this function:
function toggleSeries (legend,num) {
dojo.query("*",legend.legends[num])[0].click();
dijit.findWidgets(legend.legends[num])[0]._onClick(); }
It doesn't use any class definition (because of the *) and it accesses the areas where the checkboxes are from within the SelectableLegend. It needs the SelectableLegend and the number of the series you want to deactivate as parameters. Here the jsfiddle example with this function & hiding all 4 of your series with it:
http://jsfiddle.net/luciancd/92Dzv/17/
Also please notice the "onDomReady" Option in jsfiddle, without it: doesnt work in IE.
And the ready function within the code !
Lucian
I have updated your code http://jsfiddle.net/92Dzv/18/
Here is the key to toogle.
dom.byId(le._cbs[0].id).click();
dom.byId(le._cbs[2].id).click();
Choose the index of your legend and set to _cbs.
By this way le._cbs[0].id you will get the real id of checkbox (that inside in the widget) and then just use click()
Note : le is came from here.
var le = new Legend({
chart: chart,
horizontal: false
}, legend);
I have a SharePointWebControls:UserField in a page layout that needs to be excluded from spell checking, as otherwise whenever a user is selected there are a large number of spelling errors are detected in the code-behind for the control.
It seems that in Sharepoint 2007 this behaviour could be implemented by using excludefromspellcheck = "true" but this doesn't seem to work for Sharepoint 2010. Has anyone come across the same problem and found a way around it?
Based on SpellCheckEntirePage.js, that appears to still be the way:
var elements=document.body.getElementsByTagName("*");
for (index=0; index < elements.length;++index)
{
if (null !=elements[index].getAttribute("excludeFromSpellCheck"))
{
continue;
}
// snipped - if (elements[index].tagName=="INPUT")
// snipped - else if (elements[index].tagName=="TEXTAREA")
}
But excludeFromSpellCheck is not a property of UserField, so it probably won't automatically copy down to the rendered HTML. When rendered, the UserField control is made up of several elements. I would try looking at the View Source to see if excludeFromSpellCheck is making it into the final HTML. But to set the attribute on the appropriate elements, you might need to use some jQuery like this:
$("(input|textarea)[id*='UserField']").attr("excludeFromSpellCheck", "true");
You can disable the spell check for certain fields by setting the "excludeContentFromSpellCheck" attribute to "true" on text area and input controls that you dont want to be spell checked.
I did this on all my page layouts. Now i dont get false positives anymore.
The solution is to add a div tag around the fields you don't want spell checked and adding a javascript that sets "excludeFromSpellCheck" to "true" for the elements within the div tag.
The solution i found is described here: Inaccurate Spell Check on SharePoint Publishing Pages
Joe Furner posted this solution, which has worked for me.
https://www.altamiracorp.com/blog/employee-posts/spell-checking-your-custom-lay
It excludes all PeoplePickers on the page:
function disableSpellCheckOnPeoplePickers() {
var elements = document.body.getElementsByTagName("*");
for (index = 0; index < elements.length; index++) {
if (elements[index].tagName == "INPUT" && elements[index].parentNode && elements[index].parentNode.tagName == "SPAN") {
var elem = elements[index];
if (elem.parentNode.getAttribute("NoMatchesText") != "") {
disableSpellCheckOnPeoplePickersAllChildren(elem.parentNode);
}
}
}
}
function disableSpellCheckOnPeoplePickersAllChildren(elem) {
try {
elem.setAttribute("excludeFromSpellCheck", "true");
for (var i = 0; i < elem.childNodes.length; i++) {
disableSpellCheckOnPeoplePickersAllChildren(elem.childNodes[i]);
}
}
catch(e) {
}
}
This code is working partially only,because if you put the people picker value again checking the people picker garbage value for one time.
