如何使用 AngularJS 初始化 SharePoint 脚本编辑器 WebPart 内容

Question

我在使用 SharePoint 脚本 WebPart 和 AngularJS 获取要绑定的初始值时遇到问题。我已经尝试了所有不同的方法来初始化 ng-int、自定义初始化函数、准备好文档。在所有情况下，都会调用函数并设置值，但 UI 不会更新值，直到我再次与控制器交互。

在下面的代码中，{{usertitle}} 没有绑定。

所以直接的问题是在 SharePoint、Script WebPart 和 AngularJS 的上下文中成功初始化值的正确方法是什么？

只是为了展示 UI 在加载后的样子，填充了其他绑定，但没有填充 usertitle。

单击下一步按钮，然后单击上一步（在此期间未调用函数）。

HTML 在脚本编辑器中

<div id="appDiv" ng-app="myapp">
        <div id="controllerDiv" ng-controller="MyController" >
                <div class="item10 mainborder">
                    <div ng-show=showPage1() ng-init="firstFunction(this)">
                            <p class="lead">Welcome {{usertitle}}!</p>
                    </div>
                    <div>
                        <input type="button" value="Previous" ng-click="pagePrevious()" ng-disabled=showPage1() />
                        <span>{{pageXofY()}}</span>
                        <input type="button" value="Next" ng-click="pageNext()" ng-disabled=showPage6() />
                    </div>
                </div>
        </div>
    </div>

Angular 控制器 JS

        $scope.firstFunction = function ($scope) {
            //User Info-------------------------------------
            var userid = _spPageContextInfo.userId;
            var requestUri = _spPageContextInfo.webAbsoluteUrl + "/_api/web/getuserbyid(" + userid + ")";

            var requestHeaders = { "accept": "application/json;odata=verbose" };
            $.ajax({
                url: requestUri,
                contentType: "application/json;odata=verbose",
                headers: requestHeaders,
                success: onSuccessUInfo,
                error: onErrorUInfo
            });

            function onSuccessUInfo(data, request) {
                $scope.usertitle = data.d.Title;
                $scope.email = data.d.Email;
                $scope.loginname = data.d.LoginName;
                //alert(loginName);
            }

            function onErrorUInfo(error) {
                alert("error");
            }

        //End USeriNfo------------------------------------
        };
