您可以通过Jquery ajax实现.假设您有一个Web方法Report1，该方法带有2个参数fromDate和toDate.

You can achive this by Jquery ajax. Lets say you have a web method Report1 that takes 2 parameter fromDate and toDate.

[WebMethod]
public static String Report1(String fromDate,String toDate)
{
  //function body
}

现在您可以通过jquery ajax调用上述方法

now you can call the above method by jquery ajax

.ajax({ 输入:"POST"， 网址:"default.aspx/Report1"， 数据:"{fromDate:" 1/1/2011，toDate:" 6/30/2011}" contentType:"application/json; charset = utf-8"， dataType:"json"， beforeSend:function(){

.ajax({ type: "POST", url: "default.aspx/Report1", data: "{fromDate:''1/1/2011'',toDate:''6/30/2011''}" contentType: "application/json; charset=utf-8", dataType: "json", beforeSend: function () {
