How to use jQuery to get the checked checkboxes values, and put it into

  • 0

How to use jQuery to get the checked checkboxes values, and put it into a textarea immediately?

Just like this code:

<html>   <head>   </head>    <body>     <div id='c_b'>       <input type='checkbox' value='one_name' checked>       <input type='checkbox' value='one_name1'>       <input type='checkbox' value='one_name2'>     </div>        <textarea id='t'></textarea>   </body> </html>

If the id='c_d' is updated by Ajax, the below of altCognito’s code doesn’t work. Is there any good solution?

  1. Here’s one that works (see the example):

     function updateTextArea() {               var allVals = [];      $('#c_b :checked').each(function() {        allVals.push($(this).val());      });      $('#t').val(allVals);   }  $(function() {    $('#c_b input').click(updateTextArea);    updateTextArea();  });

    Update

    Some number of months later another question was asked in regards to how to keep the above working if the ID changes. Well, the solution boils down to mapping the updateTextArea function into something generic that uses CSS classes, and to use the live function to monitor the DOM for those changes.
