The example in this article describes how JQuery limits the number of checkboxes that can be selected. Share it with everyone for your reference. The specific analysis is as follows:
Since the project needs to limit the number of files that can be operated in batches, I wrote a small code
If the number of selected items is greater than the maximum allowed number, other check boxes cannot be selected
If less than then all checkboxes can be selected
<script type="text/javascript">
$(document).ready(function() {
$('input[type=checkbox]').click(function() {
$("input[name='apk[]']").attr('disabled', true);
if ($("input[name='apk[]']:checked").length >= 3) {
$("input[name='apk[]']:checked").attr('disabled', false);
} else {
$("input[name='apk[]']").attr('disabled', false);
}
});
})
</script>
<ul>
<li>
<input type="checkbox" name="apk[]" value=1 />
APK1
</li>
<li>
<input type="checkbox" name="apk[]" value=2 />
APK2
</li>
<li>
<input type="checkbox" name="apk[]" value=1 />
APK3
</li>
<li>
<input type="checkbox" name="apk[]" value=4 />
APK4
</li>
<li>
<input type="checkbox" name="apk[]" value=6 />
APK5
</li>
<li>
<input type="checkbox" name="apk[]" value=7 />
APK6
</li>
<li>
<input type="checkbox" name="apk[]" value=8 />
APK7
</li>
</ul>I hope this article will be helpful to everyone’s jQuery programming.
