我有像
这样的JSON文件[{"id":"38", "youtube":"https://www.youtube.com/watch?v=PEnuHN-Mqvg"}]
我曾试过像
这样的php JavaScriptvar str = data[i].youtube;
var res = str.split("?v=");
//raplace & is ?
var str2 = res[1];
var res2 = str2.replace("&", "?");
//asign iframe to url variable
var url = "<iframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/"+res2+"\" frameborder=\"0\" allowfullscreen></iframe>";
$("#youtube").append(url); //show tag iframe
那么我如何在AngularJS中申请?

首先,我建议使用正则表达式从youtube网址获取视频ID。 str.split("?v=");
无法在所有情况下使用,因为有效的YouTube视频网址可以采用以下任何一种形式:
其次,您需要为iframe构建html标记(嵌入代码),并使用有效的src和 bind 生成带有视图的结果字符串。像{{<iframe src="..">}}
这样的简单插值不起作用。所以使用 ng-bind-html
<div ng-bind-html="<iframe src='...'>"></div>
最后,您需要$sce
服务才能使AngularJS绑定,从而导致标记为可安全用于该上下文的值。
<div ng-bind-html="getTrustedHTML('<iframe src=...>')"></div>
其中getTrustedHTML()
是为角度上下文返回可信HTML的函数。
$scope.getTrustedHTML=function(str){
return $sce.trustAsHtml(str);
}
这是你的控制器应该是什么样子:
app.controller('MainCtrl', function($scope,$sce, yourService) {
$scope.name = 'World';
$scope.data = {};
//If you want to get the video links from a JSON
yourService.getData().then(function(res){
$scope.data = res.data;
})
$scope.postContent = ''
/* or directly use $scope.postContent = <youtube URL>
*/
$scope.parseVideoURL = function(text) {
var re = /https?:\/\/(?:[0-9A-Z-]+\.)?(?:youtu\.be\/|youtube(?:-nocookie)?\.com\S*[^\w\s-])([\w-]{11})(?=[^\w-]|$)(?![?=&+%\w.-]*(?:['"][^<>]*>|<\/a>))[?=&+%\w.-]*/ig;
return text.replace(re,
'<iframe height="100%" width="100%" src="http://www.youtube.com/embed/$1" allowfullscreen></iframe>');
}
$scope.publishVideo = function(vid){
return $scope.parseVideoURL(vid)
}
$scope.getTrustedHTML=function(str){
return $sce.trustAsHtml(str);
}
});
这里是标记
Enter a Youtube URL. Eg: 'https://www.youtube.com/watch?v=PEnuHN-Mqvg'
<br><br><br>
<input type='text' ng-model="postContent" >
<div ng-bind-html="getTrustedHTML(publishVideo(postContent))"></div>
<h3>VIDEOS FROM JSON</h3>
<div ng-repeat="v in data" ng-bind-html="getTrustedHTML(publishVideo(v.youtube))"></div>

var myApp = angular.module('myApp', []);
myApp.controller('yourController', function ($scope, testService) {
$scope.data = {};
testService.getData().then(data) {
$scope.data = data;
//loop through data I have direcctly passed 1 array element for eg
var str = data[0].youtube;
var res = str.split("?v=");
//raplace & is ?
var str2 = res[1];
var res2 = str2.replace("&", "?");
//asign iframe to url variable
$scope.url = "<iframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/"+res2+"\" frameborder=\"0\" allowfullscreen></iframe>";//please use
});
});
myApp.service('yourService', function ($http) {
this.getData = function () {
return $http.get('data.json');
}
});
在您的HTML上,如果您的div已经id为youtube(请通过此链接https://docs.angularjs.org/api/ng/directive/ngBindHtml)
<div id="youtube" ng-bind-html = "url"></div>
