Disable radio buttons based on value
提问by Ajay
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.
我想根据变量的值禁用单选按钮。应禁用等于变量值的无线电。
Ex:
前任:
<input type="radio" name="r1" value="a" />Value a
<input type="radio" name="r1" value="b" />Value b
So if the $variable = 'a';
then the radio button which has the value a
should be disabled.
因此,如果则应禁用$variable = 'a';
具有该值的单选按钮a
。

If you want to disable based by name and value, you can try this
如果你想禁用基于名称和值,你可以试试这个
var a = 'a';
var fieldName = 'r1';
$('input[type=radio][name=' + fieldName + '][value='+ a +']').prop('disabled', true);
