问题描述
我从 this 下载了一个主题 链接.我必须在 index.html 文件中定义脚本和 CSS.
I have downloaded a theme from this link. I have to define script and CSS in index.html file.
index.html(正文部分)
index.html (body section)
<body>
<app-root></app-root>
<script type="text/javascript" src="./assets/js/main.85741bff.js"></script>
<script type="text/javascript" src="./assets/js/common.js"></script>
</body>
我在 common.js 中定义了我的函数并从 main.85741bff.js 文件中调用它.
I have defind my function in common.js and call it from main.85741bff.js file.
common.js(函数)
common.js (function)
document.addEventListener("DOMContentLoaded", function (event) {
masonryBuild();
navbarToggleSidebar();
navActivePage();
});

The issue is that I am able to call the function while page reloads but can't call the function while content load.
谁能帮我解决这个问题?任何帮助将不胜感激.

推荐答案
您可以在 Angular 应用程序中使用 javascript.
You can use javascript in the Angular application.
步骤 1. 在 assets/javascript 文件夹中创建 demo.js 文件.
Step 1. Create demo.js file in assets/javascript folder.
export function test1(){
console.log('Calling test 1 function');
}
步骤 2. 在 assets/javascript 文件夹中创建 demo.d.ts 文件.
Step 2. Create demo.d.ts file in assets/javascript folder.
export declare function test1();
步骤 3. 在你的组件中使用它
Step 3. Use it in your component
import { test1 } from '../assets/javascript/demo';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
constructor() {
console.log(test1());
}
}
注意:js和.d.ts文件名要一致
