Question

I am trying to convert select boxes to radio buttons on the fly using jQuery, and I m not sure the best way.

Example HTML:

  <form id="product">    
    <select name="data[123]">
      <option value="1">First</option>
      <option value="2">Second</option>
      ......
      <option value="n">xxxxxx</option>
    </select>
  </form>

I want to convert it at page load using jquery to:

<form id="product">
  <input type="radio" name="data[123]" value="1" />
  <label for="data[123]">First</label><br/>
  <input type="radio" name="data[123]" value="2" />
  <label for="data[123]">Second</label><br/>
  ......
  <input type="radio" name="data[123]" value="n" />
  <label for="data[123]">xxxxxx</label><br/>
</form>

And it needs to be dynamic so it will loop dynamically for each select box and each option inside (as different products have different options)

I m trying to figure the best way. Either to get a multidimensional array of all the values first and then build the radio buttons.. or swap them out one at a time in a loop. Currently attempting the former, but I think I may be overthinking it:

$(document).ready(function(){
    
    //Get Exising Select Options    
    $( form#product select ).each(function(i, select){
        $(select[i]).find( option ).each(function(j, option){
            //alert($(option).text());
            option[j] = [];
            option[j][ text ] = $(option).text();
            option[j][ val ] = $(option).val();
        });
    });
    
    
    //Remove Select box
    $( form#product select ).remove();
});

Has anyone tried this or have some secret/easier way of doing it that I m missing?

Answer 1

I put this together, and tested it in a few browsers, all seem to handle it well. It will take the data out of the <option> elements and create the <input/><label/><br/> for each one, then remove the select box.

//Get Exising Select Options    
$( form#product select ).each(function(i, select){
    var $select = $(select);
    $select.find( option ).each(function(j, option){
        var $option = $(option);
        // Create a radio:
        var $radio = $( <input type="radio" /> );
        // Set name and value:
        $radio.attr( name , $select.attr( name )).attr( value , $option.val());
        // Set checked if the option was selected
        if ($option.attr( selected )) $radio.attr( checked ,  checked );
        // Insert radio before select box:
        $select.before($radio);
        // Insert a label:
        $select.before(
          $("<label />").attr( for , $select.attr( name )).text($option.text())
        );
        // Insert a <br />:
        $select.before("<br/>");
    });
    $select.remove();
});

You re on the right track. Iterate and collect the select data into variables and make as few DOM operation calls as possible (for efficiency) to create the radio inputs.
