I have some question with these events.
My code is something like this:
dialogX.find('#inputExample').blur(function() {
var button = $(this).parent().find('#buttonExample');
if(!(button.is(':clicked'))) //this doesn't work, just test
button.hide();
});
dialogX.find('#buttonExample').live('click', function() {
alert('Test!');
$(this).hide();
});
The question is, when I'm on input (#inputExample) and later click on button (#buttonExample), blur is called and live event is never called.
***I have to use live instead of on, because JQuery version.
Someone could help me?
dialogX.find('#inputExample').blur(function() {
var button = $(this).parent().find('#buttonExample');
if(disableBlur)
button.hide();
});
var disableBlur = false;
dialogX.live('mousedown', function(e) {
if($(e.target).prop('id')=='buttonExample')
disableBlur = true;
else
disableBlur = false;
});

I have an input and a clear button. If the user type something in the input field and blur it, change() will be trigger and do something. But if I want to click clear button and trigger click(), change() will still be triggered. How do I solve this?
I tried this, but it doesn't work. var clear will never be true.
$("#inputid").change(function() {
var clear = false;
$("#clearbtn").click(function() {
// if clear button is clicked, do something
clear = true;
});
if (clear) {
return;
}
// if clear button is not clicked, do something else
...
this is quite tricky
the problem is onchange event is called before the clear button click event is called
to overcome this you can introduce a timer in the onchange event so that it waits for user's immediate action
like this:
$(document).ready(function(){
var clear = false;
var isTimerOn = false;
function HandleChange(){
if(clear){
// if clear button is clicked, do something
$("#inputid").val("");
}else{
// if clear button is not clicked, do something else
alert("do something else");
}
clear = false;
isTimerOn = false;
}
$("#inputid").change(function() {
isTimerOn = true;
setTimeout(HandleChange, 80);
});
$("#clearbtn").click(function() {
clear = true;
if(!isTimerOn){
HandleChange();
}
});
});
here's fiddle: https://jsfiddle.net/6d9r1qsc/
You should move the click event outside of the change event.
$("#clearbtn").click(function() {
// if clear button is clicked, do something
$("#inputid").val("");
});
I have function which has keyup event on input field which is working fine.
I want to trigger this function also upon click on other button.
Here is my function
function validateChild(el) {
var validated = {};
console.log('Remove button clicked');
var dateOfBirthField = $(el).find('.date_of_birth');
$(dateOfBirthField).on("keyup", function () {
var dateOfBirthValue = $(el).find('.date_of_birth').val();
console.log('Check DoB');
if(validateDateOfBirth(dateOfBirthValue, dateOfBirthField)){
console.log('True');
validated.dateOfBirth = true;
} else {
validated.dateOfBirth = false;
}
validateButton(validated);
});
}
I'm calling this function on document load
function validateForms() {
$(document).find(".child-form").each(function () {
validateChild(this);
});
}
Here i have click event
.on('click', '.removeButton', function (event) {
validateForms();
});
When i click on this remove button it trigger but stop working after this
console.log('Remove button clicked');
How can i trigger keyup event also on this remove button, or there is better way to do this in javascript.
Can anyone help me with this?
Thanks
I have reviewed your three code blocks. Please try following three code blocks respectively.
Your function
function validateChild(dateOfBirthField) {
var validated = {};
var dateOfBirthValue = $(dateOfBirthField).val();
console.log('Check DoB');
if(validateDateOfBirth(dateOfBirthValue, dateOfBirthField)){
console.log('True');
validated.dateOfBirth = true;
} else {
validated.dateOfBirth = false;
}
validateButton(validated);
}
Call this function on document load
function validateForms() {
$('.child-form').on('keyup', '.date_of_birth', function() {
validateChild(this);
});
}
Click event
.on('click', '.removeButton', function() {
console.log('Remove button clicked');
$('.child-form .date_of_birth').each(function() {
validateChild(this);
});
});
Can someone explain me why this snippet can't work ?
I can't use specific features like window.location, submit(), (instead of trigger()), because this function is bound to elements that are very differents.
$('a, button').bind('click', function(oEvent, oData) {
var oButton = $(this);
var bSkip = (oData && oData.skip);
if(true === bSkip) {
return true;
} else {
oEvent.preventDefault();
//oEvent.stopPropagation();
if(confirm('This is a confirm box')) {
$(oButton).trigger('click', { skip: true });
}
}
});
Thanks in advance ! ;)
In your case even though the click event gets fired the default behavior of the links may not be triggered because of the constraints imposed by the browser
If I understand what you are trying to do correctly(if the action s not confirmed then cancel the default behavior), then you can achieve it by the below... there is no need to fire the event again
$('a, button').bind('click', function (oEvent, oData) {
if (confirm('This is a confirm box')) {
return true;
} else {
oEvent.preventDefault();
}
});
Demo: Fiddle
I need to temporarily change the click event for an element as follows:
var originalEvent = '';
$("#helpMode").click(function (e) {
originalEvent = $("#element").getCurrentClickEventHandler();
$("#element").click(function (e) {
//Do something else
});
});
//Later in the code
$("#helpModeOff").click(function (e) {
$("#element").click(originalEvent);
});
How would I store the current function that is an event handler in a global variable for later reuse?
EDIT: Here's what im trying to do:
var evnt = '';
$("#helpTool").click(function (e) {
if(!this.isOn){
evnt = $("#Browse").data('events').click;
$("#ele").unbind('click');
$("#ele").click(function (e) {
alert('dd');
});
this.isOn=true;
}else{
this.isOn = false;
alert('off');
$("#ele").unblind('click');
$("#ele").click(evnt);
}
});
Here you go, figured it out:
Now with e.srcElement.id you can get either HelpMode or HelpModeOff and then can turn on/off your help stuff!
http://jsfiddle.net/zcDQ9/1/
var originalEvent = '';
$('#element').on('yourCustomEvent', function (e) {
// do stuff
alert(originalEvent);
$(this).toggleClass('toggleThing');
//test for helpMode or helpModeOff here now...
});
$("#helpMode").on('click', function (e) {
originalEvent = e.srcElement.id;
$("#element").trigger('yourCustomEvent');
});
//Later in the code
$("#helpModeOff").on('click', function (e) {
originalEvent = e.srcElement.id;
$("#element").trigger('yourCustomEvent');
});
Okay. In jQuery 1.7 I guess it's a little different.
//get the handler from data('events')
$.each($("#element").data("events"), function(i, event) {
if (i === "click") {
$.each(event, function(j, h) {
alert(h.handler);
});
}
});
http://jsfiddle.net/yQwZU/
This is the reference.
Not sure if the following works with 1.7.
originalEvent = $('#element').data('events').click;
jQuery stored all the handlers in data. See here to learn more about data('events').
Personally, I think I would avoid manually binding and unbinding handlers.
Another way to approach this is to bind click events to classes, then all you need to do is add and remove classes from the appropriate elements when switching to/from help mode.
Here's a jsfiddle illustrating what I mean.
Switching to and from help mode then just involves adding removing classes:
$('#btnhelpmode').click(function(){
if(!helpMode){
helpMode = true;
$('.normalmode').addClass('helpmode').removeClass('normalmode');
$(this).val('Switch to normal mode...');
}else{
helpMode = false;
$('.helpmode').addClass('normalmode').removeClass('helpmode');
$(this).val('Switch to help mode...');
}
});
and you just create the handlers required, binding them to the appropriate classes:
$('#pagecontent').on('click', '#element1.normalmode', function(){
alert('element1 normal mode');
});
$('#pagecontent').on('click', '#element1.helpmode', function(){
alert('element1 help mode');
});
$('#pagecontent').on('click', '#element2.normalmode', function(){
alert('element2 normal mode');
});
$('#pagecontent').on('click', '#element2.helpmode', function(){
alert('element2 help mode');
});

Following the jsfiddle link there is a simplified sample of what I need. Currently it shows the calendar on button click, and hides it on input blur.
What I cannot implement additionally is hiding calendar on button click.
So - calendar should:
open on button click if hidden (done)
hide on blur (done)
hide on button click if opened (this is what I'm in stuck with, because blur is triggered before button click event so I have no chance to handle it properly)
UPD:
the solution is expected to work correctly in all cases, like "mousedown on button, drag below, mouseup" (otherwise I wouldn't ask it ;-)
Try this:
var $calendar = $('#calendar');
var mousedown = false;
$('#calendar-input').blur(function() {
if (!mousedown)
$calendar.hide();
});
$('#calendar-button').mousedown(function() {
mousedown = true;
});
$('#calendar-button').mouseup(function() {
mousedown = false;
});
$('#calendar-button').click(function() {
if ($calendar.is(':visible')) {
$calendar.hide();
}
else {
$calendar.show();
$('#calendar-input').focus();
}
});
Demo here: http://jsfiddle.net/Tz73k/
UPDATE: OK, I moved the mouseup event to the document level. I don't think the mouse state can be tricked now by dragging the mouse before releasing it:
var $calendar = $('#calendar');
var mousedown = false;
$('#calendar-input').blur(function() {
if (!mousedown)
$calendar.hide();
});
$('#calendar-button').mousedown(function() {
mousedown = true;
});
$(document).mouseup(function() {
mousedown = false;
});
$('#calendar-button').click(function() {
if ($calendar.is(':visible')) {
$calendar.hide();
}
else {
$calendar.show();
$('#calendar-input').focus();
}
});

It's helpful to think of the calendar and the button as a set, where you only hide the calendar when everything in the set has blurred. To do this you need a system where focus can be "handed off" between the calendar and button without triggering your hide function. To do this you'll need a focus and blur handler on both your calendar and your button, as well as a state variable for isFocused.
var isFocused;
jQuery('#calendar,#calendar-button,#calendar-input').blur(function(){
isFocused = false;
setTimeout(function() {
if (!isFocused) { hide(); }
}, 0);
});
jQuery('#calendar,#calendar-button,#calendar-input').focus(function(){
isFocused = true;
});
The setTimeout is because, when you click the button, focus is lost on calendar before it's gained on the button, so there's momentarily nothing in focus.
Edit
I guess there's actually three elements in the set, the button, the textbox, and the calendar. I updated the example. This also fixes the issue that, in your example, you can't click between the calendar and the textbox without the calendar hiding. Presumably the real calendar can be manipulated by clicking it.
Edit 2
For this to work you'll need to make your calendar focusable by giving it a tabindex.
<span id="calendar" tabindex="-1">I'm a calendar ;-)</span>
