基于团队可见的按钮

Question

按钮应该可见基于团队。示例如果“测试团队”的登录用户部分，“测试按钮”应该启用。如果不禁用。我正在使用 webapi。但它给出的是空值。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'>" +
                    "    <attribute name='name' />" +
                    "    <attribute name='businessunitid' />" +
                    "    <attribute name='teamid' />" +
                    "    <attribute name='teamtype' />" +
                    "    <order attribute='name' descending='false' />" +

            // debugger;
            req1.onreadystatechange = null;
            if (this.status == 200) {
                var reqResults = JSON.parse(this.response).value;
                if (reqResults != null && reqResults.length > 0) {
                    if ("TestTeam"==reqResults.length[i].name){return true;}

                else{return false;}
                }

感谢您发布示例代码。它有一些语法错误，但我认为这是因为您为帖子编辑了它。例如，for 循环不存在并且括号丢失。

1. 请求是异步的。从您的方法返回未定义。您要么希望将 XMLHttpRequest 更改为同步运行（出于用户体验原因通常不推荐），要么在有结果时传入回调以调用。这里我添加了 onSuccess 和 onError。 onSuccess 将 true/false 作为参数，即是否找到了 TestTeam。

2. 在你的 for 循环中，你有 reqResults.length[i]，你可能指的是 reqResults[i]。同样，这可能只是发布编辑的问题。

因此，如果 TestTeam 是用户的团队之一，则此代码将调用值为 true 的 onSuccess。如果不是，则为 false。或者如果发生错误，它将调用 onError。您可以进行编辑以构建一组要传回的团队等。或者您可以编辑 .open() 调用，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'>" +
                        "  <entity name='team'>" +
                        "    <attribute name='name' />" +
                        "    <attribute name='businessunitid' />" +
                        "    <attribute name='teamid' />" +
                        "    <attribute name='teamtype' />" +
                        "    <order attribute='name' descending='false' />" +
                        "    <filter type='and'>" +
