我在AngularJS应用程序中使用SharePoint的JavaScript对象模型,并且需要在页面加载时执行其中一个函数,以便填充数组并由ng-repeat使用。
目前,它在页面加载时向控制台记录数组push,但似乎没有将值提交到数组中以便在页面/ $ scope上使用,直到我单击/然后输出输出框,单击OK在一个警告框,或一个让我在页面上的虚拟链接。这是我很困惑的原因,为什么它可以在加载时正确地记录数组,但没有在页面的$ scope中准备好数组。
我尝试了以下内容,但没有成功:
1)我已将调用执行函数移至控制器底部
2)我尝试过angular.element(document).ready
3)我尝试将其包装在以下函数中:
$scope.initTaxonomy = function () {
$(function () {
// Function here
});
};
我不明白为什么下面这个调用REST服务的内容在页面加载时执行/通过推入$ scope用于ng-repeat而完美地工作,而我的函数并没有这样做。 T:
// Array holding items for display on homepage
$scope.items = [];
appItems.query(function (result) {
// Data is within an object of "value", so this pushes the server side array into the $scope array
var result = result.value;
var userInfo;
// Foreach result, push data into items array
angular.forEach(result, function (resultvalue, resultkey) {
$scope.items.push({
title: resultvalue.Title,
status: resultvalue.Status
});
});
});
这是在页面加载时成功登录控制台的功能,但不会在我的ng-repeat中填充数组,直到我在页面上点击:
var termsArray = [];
$scope.termsArray = termsArray;
execOperation();
function execOperation() {
//Current Context
var context = SP.ClientContext.get_current();
//Current Taxonomy Session
var taxSession = SP.Taxonomy.TaxonomySession.getTaxonomySession(context);
//Term Stores
var termStores = taxSession.get_termStores();
//Name of the Term Store from which to get the Terms.
var termStore = termStores.getByName("Taxonomy_1111");
//GUID of Term Set from which to get the Terms.
var termSet = termStore.getTermSet("1111111");
var terms = termSet.getAllTerms();
context.load(terms);
context.executeQueryAsync(function () {
var termEnumerator = terms.getEnumerator();
while (termEnumerator.moveNext()) {
var currentTerm = termEnumerator.get_current();
var guid = currentTerm.get_id();
var guidString = guid.toString();
termsArray.push({
termName: currentTerm.get_name(),
termGUID: guidString,
});
//getLabels(guid);
}
console.log($scope.termsArray)
}, function (sender, args) {
console.log(args.get_message());
});
};
我的控制器通过app.js加载页面,如下所示:
$routeProvider.
when('/', { templateUrl: '/views/home.html', controller: 'appHomeItemsCtrl' }).
when('/add-item', { templateUrl: '/views/add-item.html', controller: 'appItemPostCtrl' }).
otherwise({ redirectTo: '/' });
这是一个问题,SharePoint的JSOM需要正确执行某些内容,我是如何尝试在AngularJS中执行的,还是其他什么?
答案 0 :(得分:0)
我能够让这个工作。问题是Angular似乎不尊重非Angular函数,因此使用$ scope.apply将数组推送到$ scope是有效的。请注意,包装整个函数会导致Angular的摘要出现问题:
var termsArray = [];
execOperation();
function execOperation() {
//Current Context
var context = SP.ClientContext.get_current();
//Current Taxonomy Session
var taxSession = SP.Taxonomy.TaxonomySession.getTaxonomySession(context);
//Term Stores
var termStores = taxSession.get_termStores();
//Name of the Term Store from which to get the Terms.
var termStore = termStores.getByName("Taxonomy_1111");
//GUID of Term Set from which to get the Terms.
var termSet = termStore.getTermSet("1111");
var terms = termSet.getAllTerms();
context.load(terms);
context.executeQueryAsync(function () {
var termEnumerator = terms.getEnumerator();
while (termEnumerator.moveNext()) {
var currentTerm = termEnumerator.get_current();
var guid = currentTerm.get_id();
var guidString = guid.toString();
termsArray.push({
termName: currentTerm.get_name(),
termGUID: guidString,
});
}
console.log(termsArray)
$scope.$apply(function () {
$scope.termsArray = termsArray;
});
}, function (sender, args) {
console.log(args.get_message());
});
};
