How do I check whether a checkbox is checked in jQuery?
Posted By: Anonymous
I need to check the checked
property of a checkbox and perform an action based on the checked property using jQuery.
For example, if the age
checkbox is checked, then I need to show a textbox to enter age
, else hide the textbox.
But the following code returns false
by default:
if ($('#isAgeSelected').attr('checked')) {
$("#txtAge").show();
} else {
$("#txtAge").hide();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" id="isAgeSelected"/>
<div id="txtAge" style="display:none">
Age is selected
</div>
How do I successfully query the checked
property?
Solution
This worked for me:
$get("isAgeSelected ").checked == true
Where isAgeSelected
is the id of the control.
Also, @karim79’s answer works fine. I am not sure what I missed at the time I tested it.
Note, this is answer uses Microsoft Ajax, not jQuery
