jQuery和AJAX元素调用具有JavaScript代码吗？

Question

I have a simple form which has only one textarea element.

We use this text area to pass JavaScript code and save it into a MySQL database using PHP.

It works fine with any text, but not with text which has the JavaScript

$(function(){

      $("#hotbar").submit(function(){
          $.ajax({type:'POST', 
            url: 'modules/hotbar.php', 
            data:$('#hotbar').serialize(),
            beforesubmit : function() {
              return $('#hotbar').validate().form();
               },
            success: function(response) {
            $('#action').html(response);
        }
    });

       return false ;   
      });


});

It works fine with any text only; when passing the JS code we want to save it does nothing and never lets the value pass to the PHP page

没有更多细节很难说，但是我首先要检查jQuery验证插件或服务器端的某些表单处理组件是否正在删除脚本标签，以尝试保护您免受跨站点脚本（XSS）攻击。
