我需要加载一个模块,尽管它在网络上很普遍,并且我尝试了一些解决方案,但似乎无法解决该错误:
我有一个这样的班级:
export class Example{
public Name: string;
public Id: number;
}
将类导入app.js文件:
import { Example } from "./exampleClass";
let example = new Example();
example.Name = "Hello World";
document.write(example.Name);
尝试过:
首先在tsconfig中
"module": "system"
<html>
<head>
<meta charset="UTF-8">
<title>Title of the document</title>
<script src="node_modules/systemjs/dist/system.js"></script>
</head>
<body>
<script>
SystemJS.config({
baseURL: '/',
defaultJSExtensions: true
});
SystemJS.import('./dist/app.js');
</script>
</body>
</html>
这:
<script>
SystemJS.config({
baseURL: '/',
packages: {
'/': {
defaultJSExtensions: 'js'
}
}
});
SystemJS.import('./dist/app.js');
</script>
答案 0 :(得分:0)
使用方法“ System.import()”代替方法“ SystemJS.config()”。例如,请参见HTML文件“ index.html”文件:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Learning TypeScript</title>
<script src='node_modules/systemjs/dist/system.js'></script>
</head>
<body>
<div id="app">Change it with jQuery</div>
<script>
System.import('./app.js');
</script>
</body>
</html>
请确保在“ package.json”文件中包含以下代码,因为您将SystemJS用作模块加载器:
"dependencies": {
"systemjs": "^6.1.2"
},
请确保在TypeScript配置文件“ tsconfig.json”文件中包含以下代码,因为您将SystemJS用作模块加载器:
"compilerOptions": {
"module": "system", /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */
