    jQuery调用WebService详解

    我在这里将jQuery Ajax 调用Aspx.Net WebService 的几个常用的方法做了一个整理。

    <script src="jquery.js" type="text/javascript"></script>

    <style type="text/css">
    .hover
    {
    cursor: pointer; /*小手*/
    background: #ffc; /*背景*/
    }
    .button
    {
    150px;
    float: left;
    text-align: center;
    margin: 10px;
    padding: 10px;
    border: 1px solid #888;
    }
    #dictionary
    {
    text-align: center;
    font-size: 18px;
    clear: both;
    border-top: 3px solid #888;
    }
    #loading
    {
    border: 1px #000 solid;
    background-color: #eee;
    padding: 20px;
    margin: 100px 0 0 200px;
    position: absolute;
    display: none;
    }
    #switcher
    {
    }
    </style>

    <script type="text/javascript">


    //无参数调用
    $(document).ready(function() {
    $('#btn1').click(function() {
    $.ajax({
    type: "POST", //访问WebService使用Post方式请求
    contentType: "application/json", //WebService 会返回Json类型
    url: "WebService1.asmx/HelloWorld", //调用WebService的地址和方法名称组合 ---- WsURL/方法名
    data: "{}", //这里是要传递的参数,格式为 data: "{paraName:paraValue}",下面将会看到 
    dataType: 'json',
    success: function(result) { //回调函数,result,返回值
    $('#dictionary').append(result.d);
    }
    });
    });
    });


    //有参数调用
    $(document).ready(function() {
    $("#btn2").click(function() {
    $.ajax({
    type: "POST",
    contentType: "application/json",
    url: "WebService1.asmx/GetWish",
    data: "{value1:'心想事成',value2:'万事如意',value3:'牛牛牛',value4:2009}",
    dataType: 'json',
    success: function(result) {
    $('#dictionary').append(result.d);
    }
    });
    });
    });


    //返回集合(引用自网络,很说明问题)
    $(document).ready(function() {
    $("#btn3").click(function() {
    $.ajax({
    type: "POST",
    contentType: "application/json",
    url: "WebService1.asmx/GetArray",
    data: "{i:10}",
    dataType: 'json',
    success: function(result) {
    $(result.d).each(function() {
    //alert(this);
    $('#dictionary').append(this.toString() + " ");
    //alert(result.d.join(" | "));
    });
    }
    });
    });
    });


    //返回复合类型
    $(document).ready(function() {
    $('#btn4').click(function() {
    $.ajax({
    type: "POST",
    contentType: "application/json",
    url: "WebService1.asmx/GetClass",
    data: "{}",
    dataType: 'json',
    success: function(result) {
    $(result.d).each(function() {
    //alert(this);
    $('#dictionary').append(this['ID'] + " " + this['Value']);
    //alert(result.d.join(" | "));
    });

    }
    });
    });
    });

    //返回DataSet(XML)
    $(document).ready(function() {
    $('#btn5').click(function() {
    $.ajax({
    type: "POST",
    url: "WebService1.asmx/GetDataSet",
    data: "{}",
    dataType: 'xml', //返回的类型为XML ,和前面的Json,不一样了
    success: function(result) {
    //演示一下捕获
    try { 
    $(result).find("Table1").each(function() {
    $('#dictionary').append($(this).find("ID").text() + " " + $(this).find("Value").text());
    });
    }
    catch (e) {
    alert(e);
    return;
    }
    },
    error: function(result, status) { //如果没有上面的捕获出错会执行这里的回调函数
    if (status == 'error') {
    alert(status);
    }
    }
    });
    });
    });




    //Ajax 为用户提供反馈,利用ajaxStart和ajaxStop 方法,演示ajax跟踪相关事件的回调,他们两个方法可以添加给jQuery对象在Ajax前后回调
    //但对与Ajax的监控,本身是全局性的
    $(document).ready(function() {
    $('#loading').ajaxStart(function() {
    $(this).show();
    }).ajaxStop(function() {
    $(this).hide();
    });
    });

    // 鼠标移入移出效果,多个元素的时候,可以使用“,”隔开
    $(document).ready(function() {
    $('div.button').hover(function() {
    $(this).addClass('hover');
    }, function() {
    $(this).removeClass('hover');
    });
    });
