I'm a little stuck on this. I have a javascript function that, on page load, generates a form:
All the checkboxes have the class 'cls-select'. I am trying to then run another function (I've put a console.log in for now) when any of these checkbox states are changed but it's not detecting any changes.
$(function() {
FormGenerate();
$('.cls-select').change(console.log('Something changed...'));
// ...
});
When the page is first opened, the log message appears. But, no matter what is checked / unchecked, no additional log entries appears.
Can some one explain to me why this occurs? I'm guessing it's because when the .js file is loaded by the browser, there are no checkboxes with cls-select that exist on the page so there is nothing 'there' to fire the trigger.
Is there a way around this without having to start over? Any help / advice is greatly appreciated.
Your logic is assigning the result of console.log('Something changed...') execution as event handler and that's not what you are expecting to do.
Change your code by
$('.cls-select').change(function(){
console.log('Something changed...');
});
I think it happens because when you trying to set 'onchange' event for checkboxes, they didn't appear yet. So you should use jQuery 'on' like this:
$( 'body' ).on( 'change', '.cls-select', function() {
console.log('changes!');
});
There is a problem in your code you should do like this
$(function() {
FormGenerate();
$('.cls-select').change(function(){
console.log('Something changed...');
});
});

im trying to get a lil project going but im stuck on a very annoying thing.
$(document).ready(function() {
$("#search-button").click(console.log('hello'))
});
as you can see im targeting a search button with the id search-button and as soon as i click it something should happen. in this case i put a console.log in to test if it works but it doesn't. it always logs it as soon as i load the page , not when i click the button i target. ... what am i doing wrong
if you need more info on this pls tell me i tried to keep it as simple as i could
ty for your help
O.k
The click handler needs a function argument, not just the console.log by itself. Try this:
$(document).ready(function() {
$("#search-button").click(function() {
console.log('hello');
});
});
Inside of .click should be a handler .click(handler) and the handler should be a function. The browser is reading the code and when it hits console.log('hello'), it does it! It's seeing .click etc, but it doesn't matter; it next sees console.log and does it.
Try
$(document).ready(function() {
$("#search-button").click(function() {
console.log('hello');
});
});
As others have mentioned, the click function requires its own callback function. You can also use this, without requiring the use of document:
$("#search-button").on('click', function() {
console.log('hello')
})
I hope You're using jQuery version 3 or up. if you use 3 or up jquery version the good practice is you use Document binding Example:
jQuery(document).on('click', '#search-button', function(event) {
//your Code here...
console.log('hello');
});
this is my first question here and I hope I'm asking it correct.
I'm making an userscript. The website has a chat and when a user for example clicks a message it should copy it. The website has removed right click and selecting. I know how to copy the message, but I don't know how to add the click feature part.
This is the code I have so far:
$(document).ready(function(){
$('.msg').click(function(){
$('#someinput').val($(this).text())
.select();
document.execCommand('copy');
});
});
This gives me the error Cannot read property 'click' of null, and I guess that is because the chat message isn't created yet. How do I fix this?
You must use jQuery event delegation: http://learn.jquery.com/events/event-delegation
If your .msg elements are inside a container you can write
$(document).ready(function() {
$('#container').on('click', '.msg', function() {
// your click function
});
});
I can't seem to find a solution to this problem I posted in the comments of this question
… I'm using the pace.js plugin and I would love to load/show parts of my page immediately without having to wait for the preloader to load all content.
I thought of doing this by simply calling the start event and show the selector immediately.
However I can't seem to find the cause why my done event is fired, but start is not. I also tried with hide which is also fired, but stop or restart is not.
$(window).load(function(){
Pace.on('start', function() {
alert('start') // not fired
});
Pace.on('done', function() {
alert('done') // fired!
});
});
Any ideas?
Call Pace.start(), right after event bindings. You then will be able to get the start event.
You will need to call
Pace.restart();
if the current page has already loaded with pace progress.
You have to put
Pace.on('start', function() {
alert('start');
});
outside $(window).load....
After that it will get start status, You are calling These methods after documentation is loaded so start must be already triggred.
after registering script and css, on your htlm section add this script
<script type="text/javascript">
window.onbeforeunload = renderLoading;
function renderLoading() {
Pace.stop();
//Pace.start();
Pace.bar.render();
}
I have a function which when the div is loaded it executes code:
$("#row").ready(function () {
When the page has first loaded, it fires fine, my data loads up without any problems.
How ever I would like to reload the div every time the value of a textbox is changed.
$("#startDatePicker").change(function () {
$("#row").load(document.URL);
});
Which is why I have that code there.
However when I change it, the .change event is fired, however it doesn't reload my div? Now I'm not sure if the div has been reloaded and it just doesn't fire the event or the event is not being loaded again at all.
EDIT
Thanks to the comment using an alert to check if the div is being called, I found out that is it not being called after I load it, so the next question is, how do I recall the (div).ready function again?
I think the issue is with jquery-cache.
Try it:
$("#startDatePicker").change(function () {
$("#row").load(document.URL+'?dt='+new Date().getTime(), function() {
alert( "Load was performed." ); // perform the operations here that
// that you wish to perform on .ready
});
});
See if it helps.
This is a button to close the click but it fail and not work. I would like to know what is the tab ID since i did not think i assign one when i create a tab.
Thank you.
This is my attempt
js
$("#closeTab").click(function() {
window.parent.$('#tt').tabs('close','Create List');
});
html
<input type="button" id="closeTab" value="Cancel" class="submit"/>
I found my js code is working but the button can not trigger it? Why? thank you
latest try:
<script>
$(document).ready(function(){
$("#addlist").validate();
});
$(function(){
$("#closeTab").click(function() {
window.parent.$('#tt').tabs('close','Create List');
});
});
</script>
It still doesn't work so i think it is because the upper function ? How to fix this?
================================================================================
Also, are there any ways to clear my session in using this jquery function (what should i add for instance)?**Thanks
With javascript, you have to delay the execution of certain functions (like event handlers) until the page loads fully. Otherwise, it is attempting to bind a function to an element that doesn't yet exist. With jQuery, you can pass a function to jQuery to be executed on page load very easily like this:
$(function(){ /* code goes here */ });
So to use this with your code, you would do this:
$(function(){
$("#closeTab").click(function() {
window.parent.$('#tt').tabs('close','Create List');
});
});
This way, when the jQuery attempts to bind the function to #closeTab, it happens after the page has loaded (and after #closeTab exists).
Do you have any errors in the console?
Do you include jQuery before that click binding?
Try changing the window.parent.... to alert('clicked!'); and make sure you're actually getting there.
Also, make sure the click binding is inside of a:
$(document).ready(function(){
// here
});
A script can close only the windows it creates. It cannot close the tab which it didn't create.
To rephrase, cannot close tab only if unless but when created tab by script which is same that close window.
I hope this makes sense.
Maybe the form is submitted and the browser navigates to another URL before the code could run? Try replacing function() with function(e) and adding e.preventDefault(); to the beginning of the event handler.
