如何切换内容？

Question

I would very much like to be able to toggle having an x and not having an x in

<td class="checkbox"> <input name="signed" type="checkbox" checked /> x </td>

See JSFiddle for example

http://jsfiddle.net/littlesandra88/GMSCW/

The code that is triggered when Submit is pressed is

$('form').live('submit', function(){
   $.post($(this).attr('action'), $(this).serialize(), function(response){
         // do something here on success
   },'json');
   return false;
});

I assume I have to something in the lines of

$(this).getElementByClass("checkbox").td.toggle('x');

But checked should still be updated in the <input name="signed" type="checkbox" checked />

Does anyone know how to do this?

Answer 1

Wrap the X in a span and then hide that

<td class="checkbox"> 
      <input name="signed" type="checkbox" checked />
      <span id='toggleme'>x</span>
 </td>

 //change the visibility of the x
 $('#toggleme').toggle();

// check the checkbox
$('input[name=signed]').attr('checked', true);

Answer 2

To check a checkbox in jQuery use you ELEMENT.attr("checked","checked") or the jQuery 1.6 way with ELEMENT.prop("checked", true)

Answer 3

The best idea, IMO, is to put a <label> right next to the checkbox and then toggle it with $("input[type=checkbox] + label", this).toggle() .

To change the checkbox, the examples other users gave work just fine.

This assumes you don't want to change the checkbox, just the text next to it. If you want both, here's another example:

Try looking at the code here it's based off the work by Bryan.

Answer 5

$({some identifier for your checkbox}).attr("checked",true)
