问题描述
您好我在渲染简单的角度代码时遇到一个常见错误
< pre > < ！DOCTYPE html >
< html ng-app >
< head >
< script data-require = angular.js @ * data-semver = 4.0.0 src = https://ajax.googleapis.com/ajax/libs/angularjs/1.6 .10 / angular.min.js > < / script >
< script data-require = angular.js @ * data-semver = 4.0.0 src = script.ts > < / script >
< script data-require = angular.js@* data-semver = 4.0.0 src = system.config.js > < / script >
< script data-require = angular.js @ * data-semver = 4.0.0 src = tsconfig.json > < / script >
< 链接 rel = stylesheet href = style.css / >
< script src = script.js > < / script >
< / head >
< body ng-controller =' mainctrl' >
< h1 > Hello Plunker！< / h1 >
< < span class =code-leadattribute> p > {{message}} < / p >
< / body >
< / html >
我的Javascript代码是：
让 mainctrl = function （$ scope）{
$ scope.message = ' Hello Angular！' ;
}
当我渲染这段代码时，我得到一行错误
[$ controller：ctrlreg] http://errors.angularjs.org/1.6.10/$controller/ctrlreg?p0=mainctrl
我是Angular的初学者，可能出现什么问题？
我尝试了什么：
我尝试渲染代码，但找不到任何可能产生错误的东西。我也尝试删除行
< pre>< script data-require = angular.js @ * data-semver = 4.0.0 src = system.config.js> ; < / script>
因为它在此行显示错误
解决方案
< blockquote> scope）{
scope.message = ' Hello Angular！'< /跨度>;
}
当我渲染这段代码时，我得到一行错误
controller：ctrlreg] http://errors.angularjs.org/1.6.10/
Hi I am coming across one common error in rendering simple angular code
<pre><!DOCTYPE html>
<html ng-app>
<head>
<script data-require="angular.js@*" data-semver="4.0.0" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.10/angular.min.js"></script>
<script data-require="angular.js@*" data-semver="4.0.0" src="script.ts"></script>
<script data-require="angular.js@*" data-semver="4.0.0" src="system.config.js"> </script>
<script data-require="angular.js@*" data-semver="4.0.0" src="tsconfig.json"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller='mainctrl'>
<h1>Hello Plunker!</h1>
<p>{{ message }}</p>
</body>
</html>
My Javascript code is:
let mainctrl = function($scope) {
$scope.message='Hello Angular!';
}
When I render this code I get a line of errors
[$controller:ctrlreg] http://errors.angularjs.org/1.6.10/$controller/ctrlreg?p0=mainctrl
I am a beginner to Angular, What could be the possible problem?
What I have tried:
I tried rendering the code, but could not find any thing which could create error. I also tried removing line
<pre><script data-require="angular.js@*" data-semver="4.0.0" src="system.config.js"> </script>
since it showed error in this line
解决方案
scope) {
scope.message='Hello Angular!'; }
When I render this code I get a line of errors
controller:ctrlreg] http://errors.angularjs.org/1.6.10/
