I have a bunch of checkboxes like this. If the "Check Me" checkbox is checked, all the other 3 checkboxes should be enabled, else they should be disabled. How can I do this using jQuery?
<form name="frmChkForm" id="frmChkForm">
<input type="checkbox" name="chkcc9">Check Me
<input type="checkbox" name="chk9[120]">
<input type="checkbox" name="chk9[140]">
<input type="checkbox" name="chk9[150]">
</form>

Change your markup slightly:
$(function() {
enable_cb();
$("#group1").click(enable_cb);
});
function enable_cb() {
if (this.checked) {
$("input.group1").removeAttr("disabled");
} else {
$("input.group1").attr("disabled", true);
}
}<script src=""></script>
<form name="frmChkForm" id="frmChkForm">
<input type="checkbox" name="chkcc9" id="group1">Check Me <br>
<input type="checkbox" name="chk9[120]" class="group1"><br>
<input type="checkbox" name="chk9[140]" class="group1"><br>
<input type="checkbox" name="chk9[150]" class="group1"><br>
</form>You can do this using attribute selectors without introducing the ID and classes but it's slower and (imho) harder to read.
This is the most up-to-date solution.
<form name="frmChkForm" id="frmChkForm">
<input type="checkbox" name="chkcc9" id="group1" />Check Me
<input type="checkbox" name="chk9[120]" class="group1" />
<input type="checkbox" name="chk9[140]" class="group1" />
<input type="checkbox" name="chk9[150]" class="group1" />
</form>
$(function() {
enable_cb();
$("#group1").click(enable_cb);
});
function enable_cb() {
$("input.group1").prop("disabled", !this.checked);
}
Here is the usage details for .attr() and .prop().
jQuery 1.6+
Use the new .prop() function:
$("input.group1").prop("disabled", true);
$("input.group1").prop("disabled", false);
