I'm new to JQuery in general and I want to have a function activate when ANY checkbox on the page is checked or not. Then it should check what state the checkbox is "checked" or not.
I'm not sure how to do this as all the examples I'd seen require the name of the checkbox in order to work. I'd be fine if this was in Javascript aswell.
Anyone have any ideas?
$('input[type="checkbox"]') would select all checkboxes on your page.
The following would run a function when any of your checkboxes are changed, and when checked:
$('input[type="checkbox"]').change(function(){
if($(this).is(':checked')) {//do something}
})
Bind dynamically your checkboxes to change event, and check if they are checked, then do a function of your choice.
$(document).on("change", ".chkelement", function(){
if( $(this).is(":checked") )
{
//DO SOMETHING
}
});
I recommend use a container other than "document", as close as possible to where checkboxes will be, but you get the idea right?

I am currently working with a JQuery function that determines if there are any checkboxes checked in my form. I'm using JQuery v1.10.2
This code works fine whenever I execute it with a button, but when I try to use a checkbox within the form to execute it, it does nothing. I've tested with a JFiddle, and that worked, but in my form, the alert does not fire. I've checked for redundant names, and my form id is unique. Could it be the div/table structures within the form causing some sort of conflict? The form is wrapped inside of a hidden div. Thanks for any help.
Below is the code:
<script>
$(document).ready(function(){
//$(".ksa_button_check").click(function(){
$(".ksa_check_k, .ksa_check_s").click(function(){
if ($("#ksaChecks input:checkbox:checked").length > 0) {
alert('is checked');
}
});
});
</script>
You could use something like this.
var checkboxes = $("input[type='checkbox']");
checkboxes.click(function() {
alert("Checkbox Is Checked");
});

Not sure which language you are using. If you are using PHP you could check if $_POST has a value etc. If a checkbox is checked it would have $_POST data if not it would not.
Something like this.
if(isset($_POST['submit'])) {
$checkboxes = isset($_POST['checkbox']) ? $_POST['checkbox'] : array();
foreach($checkboxes as $value) {
Do something
);
};
};
Other than that I am wondering if your checkboxes are losing its state on your form submit. So yea as others said would help to see the code.
Hi I have numbers of check boxes and below that I have a Button, which will filter data as per check box selection..
When I will click on filter button it will transfer to other page and when I click on back button the checkbox reamains checked.
but I want that when I click on back button then checkbox should be uncheck.
Any help.
For those who have similar issues, add autocomplete="off" to checkbox might help.

You can reset the checkboxes on page load using jQuery
$('input:checkbox').prop('checked', false);
Demo (Checkbox will be never checked as onload am getting rid of checked property)
ondomready (Place the below code anywhere in your document)
$(document).ready(function(){
$('input:checkbox').prop('checked', false);
});
You may use below code :
window.onbeforeunload = function() {
//unchecked your check box here.
$("input[type='checkbox']").prop('checked', false)
};
Try this when back button is clicked
Use Jquery to clear the checkboxes
$("input[type='checkbox']").each( function() {
$(this).removeAttr('checked');
});
I want to be able to run the jquery UI effect on this page:
http://jqueryui.com/toggle/
but when the user ticks or unticks a checkbox rather than clicking a button. I only want the one effect so I don't need the selection box. Basically I want some form fields to slide in or out depending on if the user checks or unchecks the checkbox.
Thanks
I've adapted the code from the jQuery UI and made this JS fiddle:
http://jsfiddle.net/m5sTY/13/
You can just add a click even to the the checkbox and see if it's checked:
$( "#effect" ).toggle( false );
$("#run_effect").click(function(){
if($('#run_effect').is(':checked')){
runEffect();
//you can do something else if the checkbox is checked here
}else{
runEffect();
//you can do something else if the checkbox is unchecked here
}
});
I removed the return false and it works fine. Try that.
I am trying to test the status of a checkbox upon its click.
My problem is that it always reports as true as it reports the status after the change event has taken place and not before.
Is there anyway I can test before the change.
Current code using jQuery - the checkboxes all of class 'package':
$(".package").click(function(){
if($(this).is(":checked")){
alert($(this).attr("checked"));
}
});
This always returns true even if selecting a checkbox that is not currently checked.
EDIT : Ok seems there was some old js interfering with the process, after cleaning that up the click function did indeed work. Thanks all.
Using the onchange event on a checkbox is not cross-browser (hello IE! And yes, even with jQuery).
The following works:
$('.package').click(function() {
console.log(this.checked) // There is no need for jQuery here
})
Logs 'true' when you check the checkbox, and 'false' when you uncheck it.
And seriously, using $(this).attr('checked') or $(this).is(':checked') is just jQueryception for nothing.
You can use the change event instead, this way you are sure the previous checked state is always the oposite of what you read now
$(".package").change(function() {
alert($(this).attr("checked"));
});
The click event fires before the actual textbox change takes place, you need to subscribe to the change event:
$(".package").change(function(){
if($(this).is(":checked")){
alert($(this).attr("checked"));
}
});
Edit: Try querying the actual Javascript object itself, should work
$(".package").change(function(){
if(this.checked){
alert(this.checked);
}
});
im very new in javascript and jquery. I have this checkbox:
<label for="editable">Editable </label><input name="editable" type="checkbox" id="edita"/>
And this jquery action:
$('#slickbox1').toggle(400);
return false;
I want to execute that action when the checkbox is checked. Thanks!
You could try:
$('#edita').change(
function() {
if ($(this).is(':checked')) {
$('#slickbox1').toggle(400);
}
});
Although it's worth noting that running the toggle() method only when it's checked (assuming that it starts off un-checked) involves the user clicking the input once to show it, and then again to remove the check and again to re-check it so that it hides as a result of the toggle().
It might be worth considering:
$('#edita').change(
function() {
if ($(this).is(':checked')) {
// checked
$('#slickbox1').show(400);
}
else {
// un-checked
$('#slickbox1').hide(400);
}
});
Which shows $('#slickbox1') if the check-box is checked, and hides it if not,
Or:
$('#edita').change(
function() {
$('#slickbox1').toggle(400);
});
Which toggles the $('#slickbox1') between show() and hide() when the input is checked and un-checked.
Edited to address the question raised by DomingoSL (the OP) in comments:
...can you please make an edit to see the procedure if now the triger is not a checkbox but a button?
There are two changes that need to be made to accommodate this:
a button has no change event, so it would have to use click() instead, and
a button has no :checked (or equivalent) state, so the if/else becomes redundant.
One way of doing it, though, and I'm assuming your element names remain the same since you've posted no information to the contrary, is:
$('#edita').click(
function(){
$('#slickbox1').toggle(400);
});
