jQuery can be used to access checkbox value using jQuery.attr(“value”) and it checked state using jQuery.prop("checked"). Note that we can not use jQuery.attr() for checked state. Here is example code snippet.
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
<input id="cb1" type="checkbox" value="val1" checked>chekbox1
<pre id="msg"></pre>
<script>
function display_cb_info() {
var value = $("#cb1").attr("value");
var isChecked = $("#cb1").prop("checked");
$("#msg").text("value=" + value + " isChecked=" + isChecked + "\n");
}
$(function() {
display_cb_info();
$("#cb1").change(display_cb_info);
});
</script>
