如何使用jQuery来调用ASP.NET web服务？ [英] How to use jQuery to call an ASP.NET web service?

问题描述

我试图使用jQuery来得到一个ASP.NET Web服务（SharePoint Server 2007的lists.asmx）的数据，但对Web服务的任何调用将真正帮助作为朝着这个方向迈出的第一步。

I'm trying to use jQuery to get data from an ASP.NET web service (SharePoint Server 2007 lists.asmx), but any call to a web service will really help as a first step in that direction.

推荐答案

我用这个方法作为包装，这样我可以发送参数。还利用变量的方法的顶部允许它在一个较高的比率被最小化，并允许一些code重用如果使多个类似的呼叫。

I use this method as a wrapper so that I can send parameters. Also using the variables in the top of the method allows it to be minimized at a higher ratio and allows for some code reuse if making multiple similar calls.

function InfoByDate(sDate, eDate){
    var divToBeWorkedOn = "#AjaxPlaceHolder";
    var webMethod = "http://MyWebService/Web.asmx/GetInfoByDates";
    var parameters = "{'sDate':'" + sDate + "','eDate':'" + eDate + "'}";

    $.ajax({
        type: "POST",
        url: webMethod,
        data: parameters,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            $(divToBeWorkedOn).html(msg.d);
        },
        error: function(e){
            $(divToBeWorkedOn).html("Unavailable");
        }
    });
}

我希望帮助。

请注意，这需要3.5框架以暴露可以以这种方式被消耗的JSON的webMethods

Please note that this requires the 3.5 framework to expose JSON webmethods that can be consumed in this manner.
