Using JQuery we can check whether a checkbox is checked or not.
Consider you have a check box like below
<input type="checkbox" id="checkbox1"/>
Using the below JQuery code, you can check whether the above checkbox is checked or not
if ($("#checkbox1").is(':checked')) { alert("checked"); // checked } else { alert("not checked"); // unchecked }
Note: is(':checked') returns TRUE if the checkbox is checked else it returns false.
You can also use below code to check checkbox is checked:
if ($("#checkbox1").attr("checked")) { alert("Checked"); } else { alert("Unchecked"); }
Note: Since jQuery 1.6, The behavior ofjQuery.attr() has changed. So it is recommended not to use it.
Javascript Code to check checkbox's checked property:
var myCheckbox = document.getElementById('checkbox1'); myCheckbox.onchange = function () { if (this.checked) { alert("checked"); } else { alert("not checked"); } }
In this way you can check whether a checkbox is checked ot not using JQuery
