Is there a way to detect when the disabled attribute of an input changes in JQuery. I want to toggle the style based on the value.
I can copy/paste the same enable/disable code for each change
event (as I did below) but I was looking for a more generic approach.
Can I create a
custom event that will monitor the disabled attribute of specified inputs?
Example:
<style type="text/css">.disabled{ background-color:#dcdcdc; }</style>
<fieldset>
<legend>Option 1</legend>
<input type="radio" name="Group1" id="Radio1" value="Yes" />Yes
<input type="radio" name="Group1" id="Radio2" value="No" checked="checked" />No
<div id="Group1Fields" style="margin-left: 20px;">
Percentage 1:
<input type="text" id="Percentage1" disabled="disabled" /><br />
Percentage 2:
<input type="text" id="Percentage2" disabled="disabled" /><br />
</div>
</fieldset>
<fieldset>
<legend>Option 2</legend>
<input type="radio" name="Group2" id="Radio3" value="Yes" checked="checked" />Yes
<input type="radio" name="Group2" id="Radio4" value="No" />No
<div id="Group2Fields" style="margin-left: 20px;">
Percentage 1:
<input type="text" id="Text1" /><br />
Percentage 2:
<input type="text" id="Text2" /><br />
</div>
</fieldset>
<script type="text/javascript">
$(document).ready(function () {
//apply disabled style to all disabled controls
$("input:disabled").addClass("disabled");
$("input[name='Group1']").change(function () {
var disabled = ($(this).val() == "No") ? "disabled" : "";
$("#Group1Fields input").attr("disabled", disabled);
//apply disabled style to all disabled controls
$("input:disabled").addClass("disabled");
//remove disabled style to all enabled controls
$("input:not(:disabled)").removeClass("disabled");
});
$("input[name='Group2']").change(function () {
var disabled = ($(this).val() == "No") ? "disabled" : "";
$("#Group2Fields input").attr("disabled", disabled);
//apply disabled style to all disabled controls
$("input:disabled").addClass("disabled");
//remove disabled style to all enabled controls
$("input:not(:disabled)").removeClass("disabled");
});
});
</script>
