My problems is that I have a drop down list and its values populated with Ajax from a jQuery call. How can I make a specific option set as the default selected option?

html

<li>
     <label>Type</label>
     <select  name="type"class="TypeSelector"></select>
     <span class="errorMessage"></span>
</li>

jQuery

$.getJSON("http://localhost/Mar7ba/Type/getAllTypes/TRUE",function(data){
            var options = '';
            options+="<option>Select Type</option>";
            for(var i=0;i<data.length;i++){
                options += "<option>"+data[i]+"</option>";
            }
            if($("#addPlace #apTypeSelect").length){
                $("#addPlace #apTypeSelect").html(options);
            }
            if($('.TypeSelector').length){
                $('.TypeSelector').html(options);
            }
        });

and the options selected is

<?php echo $question['name'];?>

I tried like this:

<li>
         <label>Type</label>
         <select  value="<?php echo $question['name'];?>"name="type"class="TypeSelector"></select>
         <span class="errorMessage"></span>
</li>

...but doesn't work what am i doing wrong ?

Do it via jQuery. Give your select an ID (I've used mySelect) and do:

$(function() {
    $("#mySelect").val("<?php echo $question['name'];?>");
});
