How to use jquery ajax to submit data in thinkcmfx. After trying to do it myself, I still can't submit it. Please help!

<code>  <script src="__TMPL__Public/js/jquery-1.10.2.min.js" type="text/javascript"></script>
   <div class="form-group">
            <label for="exampleInputEmail1">*姓名</label>
            <input type="text" class="form-control"  placeholder="" id="name" value="{$data}">
          </div>
          <div class="form-group">
            <label for="exampleInputPassword1">*电话</label>
            <input type="password" class="form-control" id="exampleInputPassword1" placeholder="" id="tel">
          </div>
          <label for="exampleInputPassword1">*给我们留言</label>
          <textarea class="form-control" rows="3" id="msg"></textarea>
        
          <button type="button" class="btn btn-default js-ajax-submit" id="subMessage" data-wait="1500">提交留言</button>
    <script type="text/javascript">
    $(function(){
    
        $("#subMessage").click(function(){
            
            $.ajax({
                   url: "__URL__/postMessage",  
                   type: "POST",

                   success: function(data,status){//如果调用php成功    
                      alert(data);
                    //document.write(data);

你ajax里的参数url写的不对吧，你那个__url__应该是一个变量，应该写成url: __URL__+"/postMessage", dataType参数不能注释
$.ajax({

<code>url: __URL__+"/postMessage",  
type: "POST",
data:{name:'name',tel:'tel',msg:'message'},//
dataType: "json",
error: function(){  
    alert('Error loading XML document');  
},  
success: function(data,status){//如果调用php成功    
    alert(data);
}</code>

});
