Using jQuery, how to locate an element when the Name and Value are known

Question

Thanks for reading this

I thought I could use find(), but couldn't make it work. I know I can add IDs or classnames, but would like to know how with the current markup.

Thanks

Here is the HTML

<input name="keywordCheckbox" type="checkbox" value="S" />
<input name="keywordCheckbox" type="checkbox" value="C" />
<input name="keywordCheckbox" type="checkbox" value="A" />

and the js

<script language="Javascript" src="javascript/jquery-1.2.6.min.js"></script>
<script type="text/JavaScript">

 $(function(){
  $('[name="keywordCheckbox"]').bind("click",
   function() {
    if($(this).attr("checked") == true) {
     switch(this.value) {
      case "A":
       var $_this = $(this) ;
       $('[name="keywordCheckbox"]').each(function() {
        if($(this).val() != $($_this).val()) { $(this).attr("checked",false); }
       });
       break ;
      default:
 DOESN'T WORK --> $('[name="keywordCheckbox"]').find('[value="A"]').attr("checked", false);}
      } // END Switch
    } // END If
  }); // End BIND
 }); // End eventlistener
 </script>

Answer 1

You should be able to chain the attribute selectors:

 $('input[name="keywordCheckbox"][value="A"]').attr("checked",false);

Will set checked to false for the input with name keywordCheckbox and value of A.

 $('input[name="keywordCheckbox"][value!="A"]').attr("checked",false);

will set checked to false for the inputs with name keywordCheckbox whose values are not A.

EDIT

I just tested the following in Firefox/Macintosh with the latest jQuery. Works fine. What version of jQuery are you using?

$(document).ready( function() {
    $('input[name=keywordCheckbox]').bind( 'click', function() {
       if (this.checked) {
          if (this.value == 'A') {              
             $('input[name="keywordCheckbox"][value!="A"]')
                .attr("checked",false);
          }
          else {
             $('input[name="keywordCheckbox"][value="A"]')
                .attr("checked",false);
          }
       }
    });
});

Answer 2

Or you could do:

$("input[name='keywordCheckbox']").filter("input[value='A']")

Then there is no need for an each function.
