将HTML插入视图 [英] Insert HTML into view
问题描述
是否可以在AngularJS控制器中创建HTML片段,并在视图中显示此HTML?
Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view?
这来自于要求将不一致的JSON blob成为 id:value
对的嵌套列表。因此,HTML是在控制器中创建的,我现在正在寻找显示。
This comes from a requirement to turn an inconsistent JSON blob into a nested list of id : value
pairs. Therefore the HTML is created in the controller and I am now looking to display it.
我已经创建了一个模型属性,但是不能在视图中渲染这个属性,而只是打印HTML。
I have created a model property, but cannot render this in the view without it just printing the HTML.
更新
看起来这个问题产生于将创建的HTML作为引号内的字符串进行角度渲染。将尝试找到一个方法。
It appears that the problem arises from angular rendering the created HTML as a string within quotes. Will attempt to find a way around this.
示例控制器:
var SomeController = function () {
this.customHtml = '<ul><li>render me please</li></ul>';
}
示例视图:
<div ng:bind="customHtml"></div>
提供:
<div>
"<ul><li>render me please</li></ul>"
</div>
推荐答案
对于Angular 1.x,使用 ng-bind-html
在HTML中:
For Angular 1.x, use ng-bind-html
in the HTML:
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
在这一点上,您将得到一个尝试使用不安全的值安全上下文
错误,因此您需要使用 ngSanitize 或 $ sce 来解决。
At this point you would get a attempting to use an unsafe value in a safe context
error so you need to either use ngSanitize or $sce to resolve that.
在控制器中使用 $ sce.trustAsHtml()
转换html字符串。
Use $sce.trustAsHtml()
in the controller to convert the html string.
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml(someHtmlVar);
ngSanitize
有两个步骤:
ngSanitize
There are 2 steps:
-
包括angular-sanitize.min.js资源,即:
< script src =lib / angular / angular-sanitize.min.js>< / script>
在js文件(控制器或通常是app.js)中,包括ngSanitize,即:
angular.module('myApp',['myApp.filters','myApp。服务','myApp.directives','ngSanitize'])
In a js file (controller or usually app.js), include ngSanitize, i.e.:
angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives', 'ngSanitize'])
