ajax thinkphp配合ajax的简单列子

我自己使用的一个ajax的列子：

HTML：

 <select class="form-control m-b" id="clien"  name="name"><option value="0">请选择</option><option value="1">蔬菜</option><option value="2">水果</option></select> <select class="form-control m-b" id="clien_state"  name="state"><option value="0">请选择</option></select>

           JS:<script src="/Public/js/jquery-1.8.3.min.js" type="text/javascript" charset="utf-8"></script><script type="text/javascript">$('#clien').change(function(){var id = $(this).val();$.ajax({url:'/Cuac/ajax_name',type:'POST',dataType:"JSON",data:{'id':id},success:function(data){if(data.status == 2){alert(data.message);return;}if(data.status == 1){$("#clien_state").html(data.message); //门店}}})});</script>  

PHP:

   public function ajax_name(){$Fruits = M('Fruits'); //水果表$id=I('post.id',0,'intval');$list = $Fruits->where('id='.$id)->select();$fru = '';foreach($list as $v){$fru .= '<option value="'.$v['id'].'">'.$v['name'].'</option>';}$this->ajaxReturn(array('list'=>$fru));   }

完成
