[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
[System.Web.Script.Services.ScriptService]

[解决办法]
function clickone() {
alert('检查是否执行了这里？');
var par = { str: "大家好！！！"};
var json_str = $.toJSON(par);
$.ajax({
url: "TestData.asmx/HelloWorld",
type:"POST",
contentType:"application/json;charset=utf-8",
dataType: "json",
data:json_str,
success: function (result) {
alret(result.d);
}
});
}
[解决办法]
仔细比对，少了什么
[解决办法]
方法里多加几个alert;看走到哪一步..
