我想知道ng-bind
,ng-bind-html
和ng-bind-html-unsafe
之间的区别。
此外,当我在代码下面运行时,我收到的错误如下所述:
代码:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<script type="text/javascript" src="/js/angular.js"></script>
<script type="text/javascript">
angular.module("myApp", []).controller("myController",function($scope)
{
$scope.getValue = function()
{
return "<b>Hello World</b>";
};
});
</script>
</head>
<body>
<div ng-app="myApp" ng-controller="myController">
<span ng-bind-html="getValue();"></span>
<span>Normal Text</span>
</div>
</body>
</html>
错误:

这是什么意思?我知道在命令式代码中使用声明性代码并不是一种好的做法,尽管我只是在<b>Hello World</b>
指令中使用ng-bind-html
。
答案 0 :(得分:2)
搜索后,我从https://docs.angularjs.org/guide/migration#ngbindhtmlunsafe-has-been-removed-and-replaced-by-ngbindhtml得到以下信息:在Angular 1.3版中,他们已经从ng-bind-html-unsafe迁移到ng-bind-html,虽然还有一个问题,为什么我会得到帖子中提到的错误?
