Jquery, getting input value with a variable

I have an post action, and when it success, i call a method and pass a the json result. Then i loop through each json object, in that loop i want to get a checkbox with objects id as a value attribute, here is how i did:

$.each(roles, function (index, role) {
        var checkboxes = $('input[value="role.RoleId"][type="checkbox"]').attr("checked",true);



    });

As you can see, i have a list of checkboxes and i want to select them when their value attribute is equal to "role.RoleId". But i couldn't manage to do it, how can i do it?

Edit: Well how can i select the wrapper element of that checkbox. it's in . so i need also select element?

Thanks

You can use the :checkbox selector to shorten your code up just a bit:

$(":checkbox[value=" + role.RoleId + "]").prop("checked", true);

You want to use concatenation here so that role.RoleId isn't interpreted literally, as plain text, but instead we want to use the value of role.RoleId.

You should use .prop instead of .attr.

.prop("checked",true);

Also you need to append the role.RoleId.. see below,

$.each(roles, function (index, role) {
        var checkboxes = $('input:checkbox[value="' + role.RoleId + '"]').prop("checked",true);
});

 var checkboxes = $('input[value="'+role.RoleId+'"][type="checkbox"]').prop("checked",true);

But set ids to the checkboxes will make problem more simple.

You have to use the value or role.RoleId like this

 var checkboxes = $('input[value="'+role.RoleId+'"][type="checkbox"]').attr("checked",true);

as role is a object from $.each loop.
