AngularJS:插入HTML进入视野 [英] AngularJS : Insert HTML into view
问题描述
是否有可能在一个角控制器创建一个HTML片段,并在视图中显示这个HTML?
这是来自一个要求把不一致的JSON一滴到 ID的嵌套列表:值
对。因此,HTML是在控制器中创建和我现在正在显示它。
我创建了一个模型属性,但在视图,而不只是打印HTML无法呈现这一点。
更新
看来,问题的角度产生渲染创建的HTML作为引号中的字符串。将试图找到解决的办法。
例如控制器:
VAR SomeController =功能(){ this.customHtml ='< UL><立GT;渲染我请< /立GT;< / UL>';
}
例视图:
< DIV NG:绑定=customHtml>< / DIV>
给出:
< DIV>
< UL><立GT;使我请< /立GT;< / UL>中
< / DIV>
有关角1.x中,使用 NG-绑定-HTML
中的HTML:
< DIV NG绑定-HTML =thisCanBeusedInsideNgBindHtml>< / DIV>
在这一点上,你会得到一个试图在安全的前提下,所以你必须要么使用的错误=https://开头的文档.angularjs.org / API / ngSanitize /服务/ $的sanitize> ngSanitize 或 $ SCE 一>,以解决这个问题。
$ SCE
使用 $ sce.trustAsHtml()
在控制器中的HTML字符串转换。
$ scope.thisCanBeusedInsideNgBindHtml = $ sce.trustAsHtml(someHtmlVar);
ngSanitize
有2个步骤:
-
包括角sanitize.min.js资源,即:结果
<脚本SRC =LIB /角/角sanitize.min.js>< / SCRIPT>
-
在一个js文件(控制器或通常app.js),包括ngSanitize,即:结果
angular.module('对myApp',['myApp.filters','myApp.services','myApp.directives','ngSanitize'])
Is it possible to create an HTML fragment in an Angular controller and have this HTML shown in the view?
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.
I have created a model property, but cannot render this in the view without it just printing the HTML.
Update
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.
Example controller :
var SomeController = function () {
this.customHtml = '<ul><li>render me please</li></ul>';
}
Example view :
<div ng:bind="customHtml"></div>
Gives :
<div>
"<ul><li>render me please</li></ul>"
</div>
For Angular 1.x, use ng-bind-html
in the HTML:
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
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.
$sce
Use $sce.trustAsHtml()
in the controller to convert the html string.
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml(someHtmlVar);
ngSanitize
There are 2 steps:
include the angular-sanitize.min.js resource, i.e.:
<script src="lib/angular/angular-sanitize.min.js"></script>
In a js file (controller or usually app.js), include ngSanitize, i.e.:
angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives', 'ngSanitize'])
