I want to disable radio buttons based on the value of a variable. The radio that is equal to the variable value should be disabled.

Ex:

<input type="radio" name="r1" value="a" />Value a
<input type="radio" name="r1" value="b" />Value b

So if the $variable = 'a'; then the radio button which has the value a should be disabled.

Answer

Try -

var a = 'a';
$("input[type=radio][value=" + a + "]").prop("disabled",true);

var a = 'a';
$("input[type=radio][value=" + a + "]").attr("disabled",true);

If you're using an older jQuery version.
