Kendo toolbar button not firing click event after being enabled

This is my logic, here I am trying to disable the save changes button and prevent click event on it if the user enters a duplicate value and enable it again if the user changes the values but after enabling it the update / save event does not occur am I doing something wrong? This is my code
function OnChange(data) {
//data.preventDefault();
$(".k-grid-save-changes")
.attr("role", "button")
.removeClass("k-state-disabled")
//.addClass("k-grid-save-changes")
.click(function () {
return true;
});
//console.log("data", data.items["0"].ProviderTypeName);
var name = data.items["0"].ProviderTypeName;
var Id = data.items["0"].Id;
var grid = $("#grid").data("kendoGrid");
//console.log("Grid ", grid);
grid.tbody.find('>tr').each(
function () {
$(this).css('background', 'white');
var dataItem = grid.dataItem(this);
//console.log(dataItem.ProviderTypeName)
if (dataItem.ProviderTypeName == name && dataItem.Id != Id) {
$(this).css('background', 'red');
$(".k-grid-save-changes")
//.removeClass("k-grid-save-changes")
.addClass("k-state-disabled")
//.removeAttr("role")
.click(function () {
return false;
});
}
});
}
This is where is call the on change event
.Events(events => events.RequestStart("OnRequestStart").Change("OnChange").RequestEnd("OnRequestEnd").Error("onError"))
If I remove the "return false;" it is working as expected but this allows duplicated values to be saved. So I have used this.

If I understand correctly in your code you do exactly what you mention as a problem. At every change you disable the save functionality with the return false. You don't enable it again at any point.
If you add an event handler to the button then you have to undo it at a later point. Since though I don't believe that the validation should occur at the change event but at the button click I would suggest to use the grid Save event where you could iterate dataSource.data() of your grid (much better) do your check and if anything happens return false.
One other way to go since you probably want the css effect with the background is to keep your code and discard the click event. Just set a flag that you could use in the save event. Something like this:
if(// your control){
$(this).css('background', 'red');
duplicatedValue = true;
}else{
.removeClass("k-grid-save-changes");
duplicatedValue = false;
}
And in the save event
function onSave(){
if(duplicatedValue){
return false;
}
}

jQuery button click once do this, click twice restart

I would like a button to turn a text element to a certain string and then restart once it is off and make it blank again.
I tried this:
$('#checkbox5').on('toggle', function() {
$("#texty5").text("Video/film");
$('#checkbox5').on('toggle', function() {
$("#texty5").text("");
});
});
But it only works the one time you press and unpress it. Thanks!

You should probably only define one "toggle" event callback, and handle both scenarios.
$('#checkbox5').on('toggle', function() {
if ($("#texty5").text() === "") {
$("#texty5").text("Video/film");
} else {
$("#texty5").text("");
}
});

Can you stop the jQuery focusout from firing when losing focus?

I've got an input box that I want to have save its value when it loses focus.
Pretty straightforward stuff and I'm able to get that done via jQuery's focusout event.
The problem however, is that I want to NOT fire the focusout event when the user clicks on an "X" icon next to the input box (example shown below)
So when the user tabs out of this input box, or clicks outside of the box or they click the green checkbox it should fire the focusout event... but if they click the red "X", it should NOT fire the focusout.
Is this possible to do with JavaScript / jQuery?
EDIT:
Some of you have recommended using event.relatedTarget, but it seems like that's returning null. I'll include my code in question for clarity:
// This is the cancel button with the red X
$("body").on("click", "span[id*='Cancel']", function(e)
{
showLabel($(this));
});
// this is the code to trigger the blur / focusout event
// trouble is that the "e.relatedTarget" is null
$("body").on("focusout", "input, textarea", function (e) {
if($(e.relatedTarget).is("span[id*='Cancel']")){
return false;
}
$(this).siblings("span[id*='OK']").trigger("click");
return false;
});
Here's a screen grab of me debugging this in JS (you'll see that the $(e.relatedTarget) selector returns nothing):

You can cancel de event returning the focus to previous element.
$('#inputText').focusout(function(event) {
setTimeout(function(){
if (document.activeElement.id == "btnCancel") {
$(event.target).focus();
return false;
}
},1);
});
This jsFiddle shows how to do it: https://jsfiddle.net/mpervh3t/
Hope it helps

You must use relatedTarget like this :
$(document).ready(function(){
$(".btn").on("focusout",function(e){
if($(e.relatedTarget).hasClass("red")) {
alert("You clicked on X button");
}
else {
alert("Fire Focus out")
}
})
})
Final code :
<!DOCTYPE html>
<html>
<head>
<style>
.gr {
color: green;
}
.red {
color: red;
}
</style>
</head>
<body>
<input type="text" class="btn"><button class="gr">Ok</button><button class="red">X</button>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(".btn").on("focusout",function(e){
if($(e.relatedTarget).hasClass("red")) {
alert("You clicked on X button");
}
else {
alert("Fire Focus out")
}
})
})
</script>
</body>
</html>

As per my comment:
"I have had to do a similar type of thing with a blur event. Basically what I had to do was call a setTimeout on the blur to execute my function to save the data, and then on the click event of the X, cancel the timeout. That way, unless the X is clicked, the save function will fire. The delay can be pretty negligable, too."
I found the relevant code
var sliderTimeout = null;
$(".slider-trigger").on("blur", function () {
sliderTimeout = setTimeout(function () {
$(".slider").hide();
}, 100);
});
$(".ui-slider-handle").on("focus", function () {
clearTimeout(sliderTimeout);
});
Here is the full demo of the code in action. It does much more than demonstrate this, but if you examine the behavior of focusing/blur on the "margin" input, you will see that if you blur the margin input, the slider hides, but if you click on the slider, it cancels the hide and stays shown. It's the exact same concept, just a slightly different application.

Here, I did the thing.
https://jsfiddle.net/kowmLf2a/1/
In the blur event I target the related target. See if that related target is the item that I don't want to blur with. If it is then return false.
Code for reference:
$('#input').blur(function(event){
if($(event.relatedTarget).is('#bt2')){
return false;
}
alert($(this).val());
});

javascript event handlers list

I am trying to prioritize click event in case two events click and change are fired.
I have a global function similar to "ValidateOnChange" and "ValidateOnClick" to validate input of text box on change and on click event.
Enter some text, it shows up error message. Then try to input correct value and click the Submit button, the error vanishes and this makes user to click the button twice. Here I am trying to fix this double click.
Here is mock up code:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</head>
<body>
<div>Enter any string:</div>
<div><input type="text" id="txtInput" ></input></div>
<div id="divError" style="color: red; display: none;">Please enter 0</div>
<input type="button" value="Submit" id="btnSubmit" ></input>
<script type="text/javascript">
var mouseevent_var = null;
function ValidateOnChange(e) {
var input = $('#txtInput').val();
if (input == '0') {
$('#divError').hide();
} else {
$('#divError').show();
}
}
function ValidateOnClick(e){
alert("Hurray!!! You got it right!");
}
$('#txtInput').mousedown(function (e) {
mouseevent_var = e;
});
jQuery(document).ready(function(){
$('#btnSubmit').click(function(e){
ValidateOnClick(e);
});
$('#txtInput').change(function(e){
ValidateOnChange(e);
});
//User don't want error when they are typing in.
//$('#txtInput').keyup(function() {
//$('#txtInput').trigger("change");
//});
});
</script>
</body>
</html>
The keyup event seemed to be solution but users don't want the error to popup when they are typing in.
Is there any way to list all the triggered events so that I could filter "mousedown" and "mouseup" events for submit button? Or is there any alternative way to prioritize click event ?

There can be many alternatives depending on the situations. I have made few minor changes to avoid the double click issue (comments amended). Basically we need to bind the mousedown event on the button object. There we will set a temporary flag variable to true. In the same time if input's change event gets fired then you can skip the checking if the temporary flag variable is true. Reason behind the double click for triggering the button's click event is better explained here: How to get jQuery click event after append in change event handler
Your updated js code below:
var mouseevent_var = false;
function ValidateOnChange(e) {
// Skip validation if the change event is fired due to user's click on submit button
if(mouseevent_var){ return false; }
var input = $('#txtInput').val();
if (input == 0) {
$('#divError').hide();
} else {
$('#divError').show();
}
}
function ValidateOnClick(e){
mouseevent_var = false; // Reset mouseevent_var to false
alert("Hurray!!! You got it right!");
}
$('#btnSubmit').mousedown(function (e) {
mouseevent_var = true;
});
jQuery(document).ready(function(){
$('#btnSubmit').click(function(e){
ValidateOnClick(e);
});
$('#txtInput').change(function(e){
ValidateOnChange(e);
});
//User don't want error when they are typing in.
//$('#txtInput').keyup(function() {
//$('#txtInput').trigger("change");
//});
});
The above code is just a fix as per your need. But there are other better alternatives too. Ideally you should not have two different validation functions for validating same fields on different events. You must think of managing it with a single function.

X-Editable: stop propagation on "click to edit"

I have an editable element inside a div which itself is clickable. Whenever I click the x-editable anchor element, the click bubbles up the DOM and triggers a click on the parent div. How can I prevent that? I know it's possible to stop this with jQuery's stopPropagation() but where would I call this method?
Here's the JSFiddle with the problem: http://jsfiddle.net/4RZvV/ . To replicate click on the editable values and you'll see that the containing div will catch a click event. This also happens when I click anywhere on the x-editable popup and I'd like to prevent that as well.
EDIT after lightswitch05 answer
I have multiple dynamic DIVs which should be selectable so I couldn't use a global variable. I added an attribute to the .editable-click anchors which get's changed instead.
editable-active is used to know if the popup is open or not
editable-activateable is used instead to know if that .editable-click anchor should be treated like it is
$(document).on('shown', "a.editable-click[editable-activateable]", function(e, reason) {
return $(this).attr("editable-active", true);
});
$(document).on('hidden', "a.editable-click[editable-activateable]", function(e, reason) {
return $(this).removeAttr("editable-active");
});
The check is pretty much like you've described it
$(document).on("click", ".version", function() {
$this = $(this)
// Check that the xeditable popup is not open
if($this.find("a[editable-active]").length === 0) { // means that editable popup is not open so we can do the stuff
// ... do stuff ...
}
})

For the click on the links, simply catch the click event and stop it:
$("a.editable-click").click(function(e){
e.stopPropagation();
});
The clicks within X-editable are a bit trickier. One way is to save a flag on weather the X-editable window is open or not, and only take action if X-editable is closed
var editableActive = false;
$("a.editable-click").on('shown', function(e, reason) {
editableActive = true;
});
$("a.editable-click").on('hidden', function(e, reason) {
editableActive = false;
});
$("div.version").click(function(e) {
var $this;
$this = $(this);
if(editableActive === false){
if ($this.hasClass("selected")) {
$(this).removeClass("selected");
} else {
$(this).addClass("selected");
}
}
});
Fixed Fiddle

It's not pretty, but we solved this problem with something like:
$('.some-class').click(function(event) {
if(event.target.tagName === "A" || event.target.tagName === "INPUT" || event.target.tagName === "BUTTON"){
return;
}
We're still looking for a solution that doesn't require a specific list of tagNames that are okay to click on.
