Data table on click on dynamic controls - datatables

I have a jquery data table that I am populating from a drop down on change event. I have two check boxes in the data table and I am running an onclick on the check boxes. But on the first click the jquery does not fire only when I click it a second time does the jquery fire, also happens on switching pages.I added the .on() for the click, because I researched and saw that dynamic controls would work that way. Is there something I'm missing also to get this click function to work on first click? Below is some of my code.
data table click on check box control no jquery click event on first click
data table click on check box control on second click
$('#my-table').on('click', function () {
var i = -1;
$("input[id*='secondary']:checkbox").on("click", function () {
if ($(this).is(':checked')) {
i = selectedIds.indexOf($(this).val());
if (i === -1) {
selectedIds.push($(this).val());
}
CheckedSecondary(this);
}
else {
jQuery(this).closest("tr").css("background-color", "");
if (selectedIds.length > 0) {
i = selectedIds.indexOf($(this).val());
if (i != -1) {
selectedIds.splice(i, 1);
}
}
if (!primaryChecked)
$(this).closest('tr').find('input[type="checkbox"]').not(this).attr('disabled', false);
}
});
$("#my-table").find("input[id*='primary']:checkbox").on("click", function () {
if ($(this).is(':checked')) {
primaryChecked = true;
primaryID = this.value;
CheckedPrimary(this);
}
else {
primaryID = "";
primaryChecked = false;
$(this).closest('tr').find('input[type="checkbox"]').not(this).attr('disabled', false);
$('input:checkbox[id^="primary"]').each(function () {
if (!$(this).closest('tr').find('input[type="checkbox"]').is(':checked'))
$(this).attr('disabled', false);
});
jQuery(this).closest("tr").css("background-color", "");
}
});
});

You're attaching click handler inside another click handler which doesn't make sense.
Remove first click handler:
$('#my-table').on('click', function () {
});
Attach the click handler to the checkboxes as follows:
$('#my-table').on('click', "input[id*='secondary']:checkbox", function () {
});
and
$('#my-table').on('click', "input[id*='primary']:checkbox", function () {
});

How to preview image in element ui?

I am using element ui el-image. And I want to preview my image when clicked with (:preview-src-list). But When I click first time it doesnt preview anything. just add's my downloaded image. So I need to click 2 times. But I want to click 1 time.
Here is my template code:
<el-image :src="src"
:preview-src-list="srcList"
#click="imgClick"></el-image>
ts code:
src = null;
srcList = [];
product = 'shoe1';
imgClick() {
prevImg(product).then(resp => {
const url = window.URL.createObjectURL(new Blob([resp.data]));
this.srclist = [url];
});
}
#Watch("product")
changed(value) {
getProductImage(value).then(resp => {
const url = window.URL.createObjectURL(new Blob([resp.data]));
this.src = url;
}).catc(e => {
alert(e);
});
}
mounted() {
this.changed(product);
}
I think these things happen because when you click on that image it will trigger clickHandler:
...
clickHandler() {
// don't show viewer when preview is false
if (!this.preview) {
return;
}
...
}
...
From source
And the preview is the computed property:
...
preview() {
const { previewSrcList } = this;
return Array.isArray(previewSrcList) && previewSrcList.length > 0;
}
...
From source
So nothing happened in the first click but after that you set preview-src-list and click it again then it works.
If you code is synchronous you can use event like mousedown which will trigger before click event.
<el-image
:src="url"
:preview-src-list="srcList"
#mousedown="loadImages">
</el-image>
Example
But if you code is asynchronous you can use refs and call clickHandler after that.
...
// fetch something
this.$nextTick(() => {
this.$refs.elImage.clickHandler()
})
...

Triggering remove event of kendo upload on click of button is not working

I want to remove selected file of kendo upload control on click event of another button and I followed the below link
Triggering OnCancel event of kendo upload on click of button the remove event fired but not clear the file below is my code. please can any one help me what i am doing wrong.
$(document).ready(function () {
$("#files").kendoUpload({
"multiple": false,
select: function (event) {
console.log(event);
var notAllowed = false;
$.each(event.files, function (index, value) {
if ((value.extension).toLowerCase() !== '.jpg') {
alert("not allowed! only jpg files!");
notAllowed = true;
}
else if (value.size > 3000000) {
alert("file size must less than 3MB ");
notAllowed = true;
}
if (event.files.length > 1) {
alert("Please select single file.");
e.preventDefault();
}
});
var breakPoint = 0;
if (notAllowed == true) event.preventDefault();
var fileReader = new FileReader();
fileReader.onload = function (event) {
var mapImage = event.target.result;
$("#sigimage").attr('src', mapImage);
document.getElementById("sigimage").style.display = 'block';
}
fileReader.readAsDataURL(event.files[0].rawFile);
},
remove: function (e) {
alert("remove");
e.preventDefault();
},
});
$("#closewindow").click(function (e) {
$("#files").data("kendoUpload").trigger("remove");
});
});
You can use the following code for removing the file inside your click function.
$(".k-delete").parent().click();
Please visit the fiddle here for a working example
You can create your custom function like this:
function remove(){
$(".k-upload-files").remove();
$(".k-upload-status").remove();
$(".k-upload.k-header").addClass("k-upload-empty");
$(".k-upload-button").removeClass("k-state-focused");
};
It will delete trigger delete of uploaded files.

dojox/checkedMultiSelect add option on top AS 'select all'

I am trying to populate the dojox/form/checkedMultiSelect with a top option named: 'select all'.
One way to do this is to use declare function to change the '_addOptionItem' function.
The problem is that this '_addOptionItem' function is using a declared object named: 'formCheckedMultiSelectMenuItem' inside the 'CheckedMultiSelect' widget, AND gives an error with: 'formCheckedMultiSelectMenuItem is not defined'.
How to fix this?
My JS code:
declare_CheckedMultiSelect: function(formCheckedMultiSelectItem){
return declare(CheckedMultiSelect, {
startup: function() {
this.inherited(arguments);
setTimeout(lang.hitch(this, function() {
this.dropDownButton.set("label", this.label);
}));
},
_addOptionItem: function(item){
var item;
if(this.dropDown){
item = new formCheckedMultiSelectMenuItem({
option: option,
parent: this.dropDownMenu
});
c(item)
this.dropDownMenu.addChild(item);
}else{
item = new formCheckedMultiSelectItem({
option: option,
parent: this
});
this.wrapperDiv.appendChild(item.domNode);
}
this.onAfterAddOptionItem(item, option);
}
});
}
Here is working prototype of what you are trying to achieve http://jsfiddle.net/894af/750/ please feel free to ask any follow up question. it is done in different way, but what I simply did is:
1) when create the mutliselect get each check box after creating using
onAfterAddOptionItem
2) listen to the select all checkbox and then override the onclick fucntion and then change the selection of all the checkboxs, based on the selection of the checkbox.
if(option.value == "SA"){
on(item, "click", function(evt){
var optionsToSelect = checkedMultiSelect.getOptions();
for(var i = 0 ; i < optionsToSelect.length;i++){
if(optionsToSelect[i].value == "SA"){
if(optionsToSelect[i].selected){
checkedMultiSelect.set("value",optionsToSelect);
}else{
checkedMultiSelect.set("value",[]);
}
}
}
});
}

dojo1.8 - Need on.pausable(fire, 'change', function()) to trigger select toggleDropdown and focus methods

Hi I have a problem and the error stated:- "Error: Target must be an event emitter."
If there is a change in fire variable and selectHandler is resumed, shouldn't the methods be triggered - toggleDropDown and focus?
Here's my code below:-
var fire = false;
var toggle1, toggle2 = true;
var select = new Select
({
store:storeA
}, 'node_Select');
select.startup();
fire = true;
var switchStore = new button
({
onClick: function()
{if (toggle1)
{
select.setStore(storeB);
toggle1 = false;
}
else
{
select.setStore(storeA);
toggle1 = true;
}
fire = true;
}
}, 'node_switchStore');
switchStore.startup();
var selectHandler = on.pausable(fire, 'change' function()
{
if(fire)
{
select.toggleDropDown();
select.focus();
fire=false;
}
})
var switchPause = new button
({
onClick: function()
{if (toggle2)
{
selectHandler.resume();
toggle2 = false;
}
else
{
selectHandler.pause();
toggle2 = true;
}
}
}, 'node_switchPause');
switchPause.startup();
What is event emitter? Only input change, button and DOM elements' events?
It seems that the fire variable is not event emitter, isn't it?
Please advise
Clement
It has to do with this line:
var selectHandler = on.pausable(fire, 'change' function()
You're trying to listen to one of javascripts primitive types, Boolean. In order for "dojo/on" to work, it has to listen to something that can fire off events. From what I'm seeing in your code sample, what you probably need is a function that handles the changing of the "fire" variable. How about something like this:
var openFire = function() {
select.toggleDropDown();
select.focus();
fire = false;
}
now instead of setting
fire=true;
you can just call
openFire();

Can we implement On key up filter option in Yii's cGridview?

I am currently trying to implement automatic filtering in Yii cGridview, By default it filters 'onclick', or 'enter' key press, But I need to change that event to "onkeyup"|
my code is like this
Yii::app()->clientScript->registerScript('search',"
$('.filters > td >input').keyup(function(){
$('#grid-id').yiiGridView('update', {
data: $(this).serialize()
});
return false;
});
");
?>
when I entered the first letter filtering occured, but after filtering and rendering the code fails.. please give me a solution.. Is there any php yii gridview extension which has filtering onkeyup
You need to change the way you attach the keyup listeners. After the gridview refreshed through AJAX, all elements inside the grid are replaced. So there's no keyup attached anymore. You can try something like:
$('body').on('keyup','.filters > td > input', function() {
$('#grid-id').yiiGridView('update', {
data: $(this).serialize()
});
return false;
});
#Michael Härtl's answer is right. But 2 Problem occur when you use this code.
1) When User Search in filter at that time, every time grid will be refresh so focus of input box will be lost.
2) When you search in one filter input and if you go to second input field field at that time first input box will be lost.
So now I have got the solution for that.
Set this java script code on your grid view.
Yii::app()->clientScript->registerScript('search', "
$('body').on('keyup','.filters > td > input', function() {
$(document).data('GridId-lastFocused',this.name);
data = $('#GridId input').serialize();
$('#GridId').yiiGridView('update', {
data: data
});
return false;
});
// Configure all GridViews in the page
$(function(){
setupGridView();
});
// Setup the filter(s) controls
function setupGridView(grid)
{
if(grid==null)
grid = '.grid-view tr.filters';
// Default handler for filter change event
$('input,select', grid).change(function() {
var grid = $(this).closest('.grid-view');
$(document).data(grid.attr('id')+'-lastFocused', this.name);
});
}
// Default handler for beforeAjaxUpdate event
function afterAjaxUpdate(id, options)
{
var grid = $('#'+id);
var lf = $(document).data(grid.attr('id')+'-lastFocused');
// If the function was not activated
if(lf == null) return;
// Get the control
fe = $('[name=\"'+lf+'\"]', grid);
// If the control exists..
if(fe!=null)
{
if(fe.get(0).tagName == 'INPUT' && fe.attr('type') == 'text')
// Focus and place the cursor at the end
fe.cursorEnd();
else
// Just focus
fe.focus();
}
// Setup the new filter controls
setupGridView(grid);
}
// Place the cursor at the end of the text field
jQuery.fn.cursorEnd = function()
{
return this.each(function(){
if(this.setSelectionRange)
{
this.focus();
this.setSelectionRange(this.value.length,this.value.length);
}
else if (this.createTextRange) {
var range = this.createTextRange();
range.collapse(true);
range.moveEnd('character', this.value.length);
range.moveStart('character', this.value.length);
range.select();
}
return false;
});
}");
Add this line to your gridview widget code.
'afterAjaxUpdate'=>'afterAjaxUpdate',
For example:
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'GridId',
'afterAjaxUpdate'=>'afterAjaxUpdate',
));
