        jQuery("#submit_button").val(eval(subBut));
        jQuery("#ui-dialog-title-dialog").text(eval(dialogTitle));


    }
  </script>

  Everything is working fine for the labels. But in the case of dynamic drop down i     got    problem. How to localize the dynamic drop down data when the user selected the   language.
 The data in the drop down is coming from the database.



 I have a language select drop down box, after selecting one language from dropdown list am able to change the text filed names and all other text in the language that is selected.

同时我有另一个下拉列表，因为数据是从数据库中动态生成的。用户从下拉列表中选择语言后，我还必须更改此下拉列表中的数据。如果你有任何想法，请建议我。

谢谢。

Answer 1

我建议你在这个问题上使用ajax。

您可以bind ajax首先下拉，然后根据从后端获得的数据填写secound下拉列表。

Answer 2

您可以这样做：

<select name='lang'>
<option value='eng'>Eng</option>
<option value='french'>French</option>

</select>

<!-- below div is another div whose data changes as per the language selected -->
<div id="another_div"></div>

JS：

$("select[name='lang']").live({
change: function(e){
    var selected_lang = $("select[name='lang'] option:selected").html();

    data = {}
    data['selected_lang'] = selected_lang;
    $.ajax({
        url: "required url",
        data: data,
        success: function(res){
           $("#another_div").text(res); // if result is a direct text sent from server
            // or
            $("#another_div").text(res.content); //if result is an object with the required content present in the key 'content'
        },
        error: function(err){
            alert("error occured");                 
        }

    });        


}
 });

我会使用众多Cascading jQuery Dropdown中的一个：
