Question

I saw this on jsfiddle and I wanted to know how I would alter it so that if and only if 45 is checked the rest are disabled, if if 45 is unselected then the rest are enabled. I should be able to do all this with out submitting the form.

The example javascript on jsfiddle:

$(function(){
    $(".rambo").change(function(){
        $(this).siblings().attr("disabled", $(this).is(":checked"));  
    });
});

Answer 1

Just add proper ids and select on that

HTML:

<input type="checkbox" id="cb1" class="rambo" value='1' /> 45 
<input type="checkbox" id="cb2" class="rambo" value='2' /> 56 
<input type="checkbox" id="cb3" class="rambo" value='3' /> 56

JS:

$(function(){
    $("#cb1").change(function(){
        $(this).siblings().attr("disabled", $(this).is(":checked"));  
    });
});
