我的角度控制器中有变量,我想在变量中获取数据并在我的html中放入脚本标记,但我不知道如何执行此操作。我这样做是因为我想拍照并用分享按钮把它放到我的LinkedIn帖子中。基于文档here,如果我可以将控制器中的数据放入脚本标记中,那么它似乎非常简单。
例如:
controller.js
.controller('PostCtrl', function ($scope, $http, $stateParams) {
$scope.test = "something";
$scope.hope = 5
$scope.array = [things];
}
HTML
<script>
var payload = {
"comment": $scope.test "content": {
"title": $scope.hope,
"someArray": $scope.array,
"submitted-url": window.location.href
}
};
</script>
////////////////////////// 感谢大量的评论。以下是我在LinkedIn上更详细的尝试:
<script type="IN/Share" data-url={{webAddress}} data-counter="right">
$.get( "https://public-api.wordpress.com/rest/v1.1/sites", function( response ) {
var post = _.first(_.filter(response.posts, function(n){return n.title.replace(/ /g,"-").replace(/[:]/g, "").toLowerCase() === $stateParams.id}));
var post1 = _.assign(post, {category: _.first(_.keys(post.categories)), pic: _.first(_.values(post.attachments)).URL, credit: _.first(_.values(post.attachments)).caption, linkCredit: _.first(_.values(post.attachments)).alt, fullStory: post.content.replace(/<(?!\s*\/?\s*p\b)[^>]*>/gi,'')});
**var image = post1.pic;**
**var title = post1.title;**
**var webAddress = window.location.href;**
function onLinkedInLoad() {
IN.Event.on(IN, "auth", shareContent);
}
function onSuccess(data) {
console.log(data);
}
function onError(error) {
console.log(error);
}
function shareContent(title, image, webAddress) {
var payload = {
"content": {
"title": title,
"submitted-image-url": image,
"submitted-url": webAddress
}
};
IN.API.Raw("/people/~/shares?format=json")
.method("POST")
.body(JSON.stringify(payload))
.result(onSuccess)
.error(onError);
}
});
</script>
我仍然认为出现了问题。但是什么?我是否正确使用http,因为到目前为止我只使用Angular。

请参阅下面的代码片段,了解如何访问角度以外的角度范围:)
编辑(阅读更新后的问题)
你最好将所有LinkedIn
脚本转码为角度方式,如kicken建议你:):
如果您仍想这样做:) ==&gt;
var app = angular.module('app', []);
app.controller('MainCtrl', function($scope) {
$scope.test = 'toto';
$scope.hope = 'My Title';
$scope.array = ['A', 'B', 'C'];
$scope.payload = {};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script>
var myFunction = function() {
var e = document.getElementById('app');
var $scope = angular.element(e).scope();
console.log($scope.payload);
$scope.payload = {
"comment": $scope.test,
"content": {
"title": $scope.hope,
"someArray": $scope.array,
"submitted-url": window.location.href
}
};
$scope.$apply();
};
</script>
<body ng-app="app" ng-controller="MainCtrl" id="app">
<p>Hello {{payload}}!</p>
<button onclick="javascript:myFunction()">Click me</button>
</body>

不是尝试将数据从Angular传递到通用<script>
标记,而是需要将LinkedIn代码移动到Angular中。
快速浏览the JavascriptSDK documentation表明这是在请求中进行链接的关键代码:
IN.API.Raw("/people/~/shares?format=json")
.method("POST")
.body(JSON.stringify(payload))
.result(onSuccess)
.error(onError);
您可以做的就是将代码放在角度代码中,无论您需要它。您提到有效负载的数据来自$ http请求,因此您可能希望将其放入$ http成功处理程序中。
$http({url:'/whatever'}).then(function(response){
var payload = { /* Generate payload */ };
IN.API.Raw("/people/~/shares?format=json")
.method("POST")
.body(JSON.stringify(payload))
.result(onSuccess)
.error(onError);
function onSuccess(){ /* LinkedIn success */ }
function onError(){ /* LinkedIn error */ }
});

正如其他人所建议的那样,如果可能的话,将所有javascript代码移动到控制器中将是最佳解决方案。为此,您的控制器看起来像这样:
.controller('PostCtrl', function ($scope, $http, $stateParams) {
$scope.test = "something";
$scope.hope = 5
$scope.array = [things];
$scope.sendData = function () {
var data = $.param({
"comment": $scope.test,
"content": {
"title": $scope.hope,
"someArray": $scope.array,
"submitted-url": window.location.href
});
var config = {
headers : {
'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
}
}
$http.post('https://api.linkedin.com/v1/people/~/shares?format=json', data, config)
.success(function (data, status, headers, config) {
//it worked
})
.error(function (data, status, header, config) {
//there was an error
});
};
}
然后,在你的html中,你会在你用来分享的表格上加上ng-submit =“sendData()”。如果共享内容不在表单中,则可以执行ng-click =“sendData()”。
