I've a simple form with a text input and a button disabled, this button can be enabled if i write on input text, keyup() is the best way but when i use right click and paste this event isn't called and doesn't trigger that event. So i tried event change(), it's work but not immediately, i must unfocus the input text for have the button enabled. How can i enable this button immediately with copy and paste?
$(document).ready(function () {
$('#id_input').bind('keyup paste click', function () {
if ($('#id_input').val().length === 6 ){
$('#btnSubmit').removeAttr('disabled');
}
else
$('#btnSubmit').attr('disabled', 'disabled');
});
});
Rory is right that your code should work in general especially if you paste using Ctrl + V.
I assume that you experience the issue only if you paste using right-click and then select Paste from the context menu.
Try to monitor the property changes:
$(document).ready(function() {
$('#id_input').bind('input propertychange', function() {
if ($('#id_input').val().length === 6) {
$('#btnSubmit').removeAttr('disabled');
} else
$('#btnSubmit').attr('disabled', 'disabled');
});
});
You need to use the onpaste event.
$(document).ready(function () {
$('#id_input').bind('keyup onpaste click', function () {
if ($('#id_input').val().length === 6 ){
$('#btnSubmit').removeAttr('disabled');
} else {
$('#btnSubmit').attr('disabled', 'disabled');
}
});
});

I use the native HTML date pickers. I want to achieve that the parent form is submitted when a date is selected by the datepickers browsers provide.
If the date is input by keyboard, I only want to submit if the enter key is pressed or on focusout.
Now my problem is that I cannot distinguish between date picker input and keyboard input, at least in Firefox. Some examples:
$(this).on('input', function(event) {
console.log(event.type);
}
This always logs 'input', no matter what I do - I would have expected that to be either "click" or "keydown" or something alike.
The on('click') handler only fires when I click on the input field, not when I click something in the date picker...
Can someone push me in the right direction?
Thanks alot
Philipp
I did a workaround which is close to what I want:
$('#eooMainForm input[type="date"]')
.each(function() {
$(this).data('serialized', $(this).serialize());
$(this).on('focusout', function() {
if($(this).serialize() != $(this).data('serialized')) {
$("#eooMainForm").form('submit');
}
});
$(this).on('keypress', function(event) {
$(this).data('byKeyPress', 1);
});
$(this).on('click', function(event) {
$(this).data('byKeyPress', 0);
});
$(this).on('change', function(event) {
//if change was done by date picker click
if($(this).data('byKeyPress') != 1 && $(this).serialize() != $(this).data('serialized')) {
$("#eooMainForm").form('submit');
}
});
});
So a keypress event listener sets the "flag" "byKeyPress" to 1, while a click events listener sets it to zero. This way, I can determine in the change event listener what caused the change.
The only situation where this does not work is when a user starts typing the date but then selects it by clicking the datepicker. I can live with that.
You'll need to attach an event which supports both event types. Using JQuery: $('a.save').bind('mousedown keypress', submitData(event, this));
Then create a JS condition:
function submitData(event, id)
{
if(event.type == 'mousedown')
{
// do something
return;
}
if(event.type == 'keypress')
{
// do something else
return;
}
}
You can find all the list of event in this image.
$('input').on('blur', function(event) {
alert(event.type);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" />
You can apply all event like the above example. Above example applied blur event on input.
I need to write an event handler when user clears the text field and moves out of focus from the same.
I'm using the following function to catch "focus out" event.
$("input[type=text]").blur(function () {
}
I have the followingfunction to capture clear field event.
$("input[type=text]").keyup(function() {
if (!this.value) {
}
}
I tried using the keyup() function inside blur() since I need to capture the focus out and then clear field. This is how my code looks like:
$("input[type=text]").blur(function () {
$(this).keyup(function() {
if (!this.value) {
}
}
}
But it doesn't work. Clear field event is triggered even before focus is out of the field. Also, it is triggering the event multiple times. What is the problem here?
I think that is more simple:
$('input').on('blur', function(e) {
if(!$(this).val()) {
// IS NO VALUE IN THE INPUT
$(this).trigger('blur'); // trigger the blur event
}
});
Here you are:
$("input[type=text]").on('blur', function() {
alert('blur');
});
$("input[type=text]").on('input', function() {
if (!$(this).val()) {
alert("input nothing");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" />
Hope this helps.
I want to detect a change in the input field when i select a value from the box like in the picture below.
html:
<input type="text" class="AgeChangeInput" id="range"/>
js:(not working)
<script>
$(document).ready(function()
{
alert("Hello");
$("#range").bind('input', function()
{
alert("done");
});
});
</script>
I also tried live on functions but they didn;t work too.
Your date selection box should fire a change event, then you only need to capture it:
$(function () {
$('#range').change(function () {
...
});
});
If the selection box doesn't fire the event, you'll need to trick the dom. Something like:
$(document).ready(function () {
// Asuming your selection box opens on input click
$('#range').click(function () {
$('.special-box-class').click(fireRangeEvent);
});
// Now the firing function
function fireRangeEvent() {
...
}
});
Hope it works
Try to use this code
changeDate - This event is fired when the date is changed.
$('#range').datepicker().on('changeDate', function(ev) {
//example of condition
if (ev.date.valueOf() > checkout.date.valueOf()) {
//make action here
alert('Here');
}
});
When user clicks on input field, two consecutive events are being executed: focus and click.
focus always gets executed first and shows the notice. But click which runs immediately after focus hides the notice. I only have this problem when input field is not focused and both events get executed consecutively.
I'm looking for the clean solution which can help me to implement such functionality (without any timeouts or weird hacks).
HTML:
<label for="example">Example input: </label>
<input type="text" id="example" name="example" />
<p id="notice" class="hide">This text could show when focus, hide when blur and toggle show/hide when click.</p>
JavaScript:
$('#example').on('focus', _onFocus)
.on('blur', _onBlur)
.on('click', _onClick);
function _onFocus(e) {
console.log('focus');
e.preventDefault();
e.stopPropagation();
e.stopImmediatePropagation();
$('#notice').removeClass('hide');
}
function _onClick(e) {
console.log('click');
$('#notice').toggleClass('hide');
}
function _onBlur(e) {
console.log('blur');
$('#notice').addClass('hide');
}
UPDATED Fiddle is here:
I think you jumbled up the toggles. No need to prevent propagation and all that. Just check if the notice is already visible when click fires.
Demo: http://jsfiddle.net/3Bev4/13/
Code:
var $notice = $('#notice'); // cache the notice
function _onFocus(e) {
console.log('focus');
$notice.removeClass('hide'); // on focus show it
}
function _onClick(e) {
console.log('click');
if ($notice.is('hidden')) { // on click check if already visible
$notice.removeClass('hide'); // if not then show it
}
}
function _onBlur(e) {
console.log('blur');
$notice.addClass('hide'); // on blur hide it
}
Hope that helps.
Update: based on OP's clarification on click toggling:
Just cache the focus event in a state variable and then based on the state either show the notice or toggle the class.
Demo 2: http://jsfiddle.net/3Bev4/19/
Updated code:
var $notice = $('#notice'), isfocus = false;
function _onFocus(e) {
isFocus = true; // cache the state of focus
$notice.removeClass('hide');
}
function _onClick(e) {
if (isFocus) { // if focus was fired, show/hide based on visibility
if ($notice.is('hidden')) { $notice.removeClass('hide'); }
isFocus = false; // reset the cached state for future
} else {
$notice.toggleClass('hide'); // toggle if there is only click while focussed
}
}
Update 2: based on OP's observation on first click after tab focus:
On second thought, can you just bind the mousedown or mouseup instead of click? That will not fire the focus.
Demo 3: http://jsfiddle.net/3Bev4/24/
Updated code:
$('#example').on('focus', _onFocus)
.on('blur', _onBlur)
.on('mousedown', _onClick);
var $notice = $('#notice');
function _onFocus(e) { $notice.removeClass('hide'); }
function _onClick(e) { $notice.toggleClass('hide'); }
function _onBlur(e) { $notice.addClass('hide'); }
Does that work for you?
Setting a variable for "focus" seems to do the trick : http://jsfiddle.net/3Bev4/9/
Javascript:
$('#example').on('focus', _onFocus)
.on('click', _onClick)
.on('blur', _onBlur);
focus = false;
function _onFocus(e) {
console.log('focus');
$('#notice').removeClass('hide');
e.preventDefault();
e.stopPropagation();
e.stopImmediatePropagation();
focus = true;
}
function _onClick(e) {
console.log('click');
if (!focus) {
$('#notice').toggleClass('hide');
} else {
focus = false;
}
}
function _onBlur(e) {
console.log('blur');
$('#notice').addClass('hide');
}
If you want to hide the notice onBlur, surely it needs to be:
function _onBlur(e) {
console.log('blur');
$('#notice').addClass('hide'); // Add the hidden class, not remove it
}
When doing this in the fiddle, it seemed to fix it.
The code you have written is correct, except that you have to replae $('#notice').removeClass('hide'); with $('#notice').addClass('hide');
Because onBlur you want to hide so add hide class, instead you are removing the "hide" calss.
I hope this is what the mistake you have done.
Correct if I am wrong, Because I don't know JQuery much, I just know JavaScript.
you can use many jQuery methods rather than add or move class:
Update: add a params to deal with the click function
http://jsfiddle.net/3Bev4/23/
var showNotice = false;
$('#example').focus(function(){
$('#notice').show();
showNotice = true;
}).click(function(){
if(showNotice){
$('#notice').show();
showNotice = false;
}else{
showNotice = true;
$('#notice').hide();
}
}).blur(function(){
$('#notice').hide();
});
I have the following code that run's when a radio button is clicked on. However I am trying to change it so it only runs if the radio button that is being clicked is NOT disabled.
Could anyone help me with this?
$('#divName').on('click', 'input[type="radio"]', function(event) { }
One way would be the use of :not()
$('#divName').on('click', 'input[type="radio"]:not([disabled])', function(event) { }
another would be to exit the function immediately if it is inactive..
$('#divName').on('click', 'input[type="radio"]', function(event) {
if (this.disabled) return;
});
You could use the :enabled selector:
$('#divName').on('click', 'input[type="radio"]:enabled', function(event) { }
But depending on what exactly you want to do, you might want to use the change event instead:
$('#divName').on('change', 'input[type="radio"]', function(event) { }
how about (not tested):
$('#divName').on('click', 'input[type="radio"]:enabled', function(event) { }
