$(function(){ $("#bt").click(function(){ $.ajax({ type:"Post", url:"antzone.aspx/mytest", data:"{'first':'蚂蚁部落','second':'欢迎您'}", contentType:"application/json;charset=utf-8", dataType:"json", success:function(data){ //返回的数据用data.d获取内容 alert(data.d); }, error:function(err){ alert(err); } }); //禁用按钮的提交 return false; }); });
