通过 Angular 2 中的所有组件加载脚本 [英] Load scripts through all components in Angular 2

问题描述

我一直在使用带有 AdminLTE 的 Angular 2，它需要运行一些脚本才能正确加载.所以我在我的 .anglular-cli.json 中添加了它们:

I have been using Angular 2 with AdminLTE which needs to run some scripts to load properly. So I have added them in in my .anglular-cli.json:

"scripts": [
    "../node_modules/jquery/dist/jquery.min.js",
    "../node_modules/bootstrap/dist/js/bootstrap.min.js",
    "../node_modules/admin-lte/dist/js/adminlte.min.js",
    "../node_modules/moment/min/moment.min.js"
],

不幸的是，这并不总是有效.页面第一次加载正常，但是当我路由到另一个页面时，不会为组件模板重新加载脚本.

Unfortunately, this does not work all time. The page loads fine the first time but when I route to another page, scripts are not reloaded for the component template.

我找不到任何关于此的信息，这让我感到非常惊讶，因为我认为这将是一个普遍的问题！我可能会完全迷失于此！

I could not find any information about this which is very surprising for me since I thought it would be a general problem! I might be totally lost with this!

推荐答案

您可以在每次需要时在 DOM 中删除和重新创建脚本元素，如下所示:

You can remove and recreate your script elements in DOM every time you need, like this:

document.getElementById("myScript").remove();
var testScript = document.createElement("script");
testScript.setAttribute("id", "myScript");
testScript.setAttribute("src", "assets/js/script.js");
document.body.appendChild(myScript);

我在 GitHub 上发布了一个问题，我解释了如何去做.

I posted a question in GitHub where I explain how to do it.
