Question

按钮应该可见基于团队。示例如果登录用户部分＆＃34;测试团队＆＃34;，＆＃34;测试按钮＆＃34;应该启用。如果没有禁用。我正在使用webapi。但它给出了null值。任何建议??

 function GetUserTeam() {
var clientUrl1 = Xrm.Page.context.getClientUrl();
var oDataPath1 = clientUrl1 + "/api/data/v8.0/";
var req1 = new XMLHttpRequest();
   try {

    var strTest = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='true'>" +
                    "  <entity name='team'>" +

感谢您发布示例代码。它有一些语法错误，但我认为这是因为你为帖子编辑了它。例如，for循环没有出现，并且缺少括号。

请求是异步的。从您的方法返回未定义。您要么将XMLHttpRequest更改为同步运行（通常不建议出于用户体验原因），要么在有结果时传入回调函数进行调用。在这里我添加了onSuccess和onError。 onSuccess将使用true / false作为参数，即是否找到TestTeam。
在你的for循环中你有reqResults.length [i]你可能在那里reqResults [i]。同样，这可能只是编辑发布的问题。

因此，如果TestTeam是用户团队之一，此代码将调用onSuccess，其值为true。假如果不是。或者如果发生错误，它将调用onError。您可以编辑以构建要传回的团队数组等。或者您可以编辑.open（）调用以使其运行synchronously并且不使用回调。

function GetUserTeam(onSuccess, onError) {
    var clientUrl1 = Xrm.Page.context.getClientUrl();
    var oDataPath1 = clientUrl1 + "/api/data/v8.0/";
    var req1 = new XMLHttpRequest();
    try {

        var strTest = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='true'>" +
