[英]How to load an Angular2 component directly on the index.html file?
[英]Angular2: Index.html doesn't display the file, only says “loading…”
我不確定如何將文件綁定到“ my-app”選擇器。 這是plnkr鏈接: http ://plnkr.co/edit/2L5jSRK3adPZWTUwWdcP?p=preview
編輯:我認為如果我將模板代碼放在index.html文件中的標簽內的插件,插棒匠可以顯示一些內容
我想知道是否有人知道如何將模板網址附加到index.html文件,以便它顯示模板網址而不是“正在加載...”
index.html文件:
<!DOCTYPE html>
<html>
<head>
<script>document.write('<base href="' + document.location + '" />');</script>
<title>Angular 2 Tour of Heroes</title>

<body>

您的配置文件有點混亂。
將文件目錄從src
更改為app
。 對於例如src/main.ts
到app/main.ts
將您的index.html
腳本標記更改為此
<script>
System.import('app').catch(function(err){ console.error(err); });
</script>
和您的config js
到
(function(global) {
var map = {
'app': 'app', // 'dist',
'rxjs': 'https://npmcdn.com/rxjs@5.0.0-beta.6',
'angular2-in-memory-web-api': 'https://npmcdn.com/angular2-in-memory-web-api' // get latest
};
var packages = {
'app': { main: 'main.ts', defaultExtension: 'ts' },
'rxjs': { defaultExtension: 'js' },
'angular2-in-memory-web-api': { defaultExtension: 'js' },
};
var packageNames = [
'@angular/common',
'@angular/compiler',
'@angular/core',
'@angular/http',
'@angular/platform-browser',
'@angular/platform-browser-dynamic',
'@angular/router',
'@angular/router-deprecated',
'@angular/upgrade',
];
packageNames.forEach(function(pkgName) {
map[pkgName] = 'https://npmcdn.com/' + pkgName + ngVer;
});
packageNames.forEach(function(pkgName) {
packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
});
var config = {
transpiler: 'typescript',
typescriptOptions: {
emitDecoratorMetadata: true
},
map: map,
packages: packages
}
if (global.filterSystemConfig) { global.filterSystemConfig(config); }
System.config(config);
})(this);
您的代碼和代碼有一些錯誤,這是代碼正確的代碼
這是在angular 2 Component中指定templateUrl和StyleUrl的方法
@Component({
selector: 'my-app',
templateUrl:"src/app.component.html",
styleUrls: ['src/app.component.css'],
})
要更改目錄或文件名,只需雙擊即可。
