【问题描述】：

我有一个共享点列表，我正在使用 Lists.asmx 使用 ajax 来获取信息，但是服务器没有返回任何内容......我做错了什么？

这是我的代码：

var Currentlocurl;

$(document).ready(function() {
    $(".vincLista").bind("click", function(){
        L_Menu_BaseUrl = "empaquetamiento"
        if (window.location.port != null || window.location.port != '') {
            Currentlocurl = window.location.protocol + "//" + window.location.hostname + ":" + window.location.port + L_Menu_BaseUrl;
           }
        else {
            Currentlocurl = window.location.protocol + "//" + window.location.hostname + L_Menu_BaseUrl;
          }

         var listurl = Currentlocurl + "/_vti_bin/lists.asmx";
         var listname = "Empaquetamiento";
         var query = "<Where>" + 
            "<And>" +
                "<Eq>" + 
                    "<FieldRef Name='Plan' />" + 
                    "<Value Type='Choice'>" + $(this).data("plan") + "</Value>" + 
                "</Eq>" + 
                "<Eq>" + 
                    "<FieldRef Name='Operacion' />" + 
                    "<Value Type='Choice'>" + $(this).data("operacion") + "</Value>" + 
                "</Eq>" + 
            "</And>" +
            "</Where>";

         var soap = "<?xml version=\"1.0\" encoding=\"utf-8\"?> \

            <GetListItems xmlns='http://schemas.microsoft.com/sharepoint/soap/'> \

            </ViewFields></viewFields> \
            </GetListItems> \
            </soapenv:Body></soapenv:Envelope>";

      $.ajax({
           url: listurl,
           beforeSend: function (xhr) {
                       xhr.setRequestHeader("SOAPAction","http://schemas.microsoft.com/sharepoint/soap/GetListItems");
                   },
          type: "POST",
          dataType: "xml",
          data: soap,
          complete: function (xData, status) {
               $(xData.responseXML).find("z\\:row").each(function () {
                    var infoDiv = $('<div/>', {class: "pieza", text: $(this).attr("ows_Nombre") + $(this).attr("ows_Descripcion")});
                    $("#info").append(infoDiv);
                  });
               },
          contentType: "text/xml; charset=utf-8"
        });
    });
});

这是我的html：

正在调用 ajax 方法，但我从来没有从服务器得到答案，甚至没有错误。

【解决方案1】：

我发现问题出在哪里，首先我在列表列中使用了锐元音，例如“operación”和“descripción”，这些词给我带来了一些麻烦，而且我的菜单基本 url 错误。

这是经过一些重构后更正的代码：

var Currentlocurl;

$(document).ready(function() {

    L_Menu_BaseUrl = "/empaquetamiento"
    if (window.location.port != null || window.location.port != '') {
        Currentlocurl = window.location.protocol + "//" + window.location.hostname + ":" + window.location.port + L_Menu_BaseUrl;
    }
    else {
        Currentlocurl = window.location.protocol + "//" + window.location.hostname + L_Menu_BaseUrl;
    }

    var listurl = Currentlocurl + "/_vti_bin/lists.asmx";
    var listname = "Empaquetamiento";

    $(".vincLista").bind("click", function(){
        var query = "<Where>" + 
            "<And>" +
                "<Eq>" + 
                    "<FieldRef Name='Plan' />" + 
                    "<Value Type='Choice'>" + $(this).data("plan") + "</Value>" + 
                "</Eq>" +
                "<Eq>" + 
                    "<FieldRef Name='Operacion' />" + 
                    "<Value Type='Choice'>" + $(this).data("operacion") + "</Value>" + 
                "</Eq>" +
            "</And>" + 
            "</Where>";

         var viewFields = "<ViewFields>\
                <FieldRef Name='Title' />\
                <FieldRef Name='Nombre' />\
                <FieldRef Name='Imagen' />\
            </ViewFields>";

        var soap = "<?xml version=\"1.0\" encoding=\"utf-8\"?> \
            <soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'> \
            <soapenv:Body> \
            <GetListItems xmlns='http://schemas.microsoft.com/sharepoint/soap/'> \
            <listName>" + listname + "</listName><query><Query>" + query + "</Query></query> \
            <viewFields>" + viewFields + "</viewFields> \
            </GetListItems> \
            </soapenv:Body></soapenv:Envelope>";

        $.ajax({
            url: listurl,
            beforeSend: function (xhr) {
                xhr.setRequestHeader("SOAPAction","http://schemas.microsoft.com/sharepoint/soap/GetListItems");
            },
            type: "POST",
            dataType: "xml",
            data: soap,
            complete: function (xData, status) {
                $(xData.responseXML).find("z\\:row, row").each(function () {
                    var infoDiv = $('<div/>', {class: "pieza", text: $(this).attr("ows_Nombre") + " - " + $(this).attr("ows_Imagen")});
                    $("#info").find("#pieza").delete;
                    $("#info").append(infoDiv);
                });
            },
            error: function(xhr, ajaxOptions, thrownError) {
                alert(thrownError);
            },
            contentType: "text/xml; charset=utf-8"
        });
    });
});

【解决方案2】：

您是否尝试过使用 FireBug 或 Chrome 的内置开发者工具调试您的服务器调用？您可以使用这些工具查看服务器调用和服务器响应。

嗨，是的，谢谢我已经发现了一些我遇到的问题，首先 L_Menu_BaseUrl = "empaquetamiento" 应该是 L_Menu_BaseUrl = "/empaquetamiento" 才能正常工作。
