在vue.js模板中包含外部脚本 [英] Including external script in vue.js template
问题描述
我是Vue.js和web-pack的新手，所以我决定使用vue-cli（webpack）来构建一个初始应用程序。我试图在一个全局不需要的模板中包含一个外部脚本（例如< script src =...）（对于每个页面/组件）但是，Vue警告说这是不允许的。
I'm new to Vue.js and web-pack, so I decided to use the vue-cli (webpack) to scaffold an initial application. I'm trying to include an external script (e.g <script src="...") in a template which isn't needed globally (for every page/component), however Vue warns that this isn't allowed.
我的index.html文件类似于最初生成的文件：
My index.html file is similar to the initial generated one:
<html lang="en">
<head>
<title>App</title>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous">
</head>
<body>
<div id="app"></div>
<!-- jQuery first, then Tether, then Bootstrap JS. -->
<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js" integrity="sha384-A7FZj7v+d/sdmMqp/nOQwliLvUsJfDHW+k9Omg/a/EheAdgtzNs3hpfag6Ed950n" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/tether/1.4.0/js/tether.min.js" integrity="sha384-DztdAPBWPRXSA/3eYEEUWrWCy7G5KFbe8fFjk5JAIxUYHKkDx6Qin1DkWx51bBrb" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js" integrity="sha384-vBWWzlZJ8ea9aCX4pEW3rVHjgjt7zpkNpZk+02D9phzyeVkE+jo0ieGizqPLForn" crossorigin="anonymous"></script>
</body>
</html>
我的App.vue也与生成的类似：
My App.vue is also similar to the generated one:
<template>
<div id="app">
<div class="container pt-5">
<router-view></router-view>
</div>
</div>
</template>
我有一条去往 / upload 的路线我的路由文件，映射到需要dropzone.js（外部脚本）的上传组件。我可以将它包含在我的index.html中，类似于如何加载引导程序，但是当只有这个组件需要它时，为每个页面/组件加载它似乎不太理想。
I have a route to /upload in my routes file, which maps to an Upload component which requires dropzone.js (an external script). I could include it in my index.html, similarly to how bootstrap is loaded, however it seems less than ideal to load it for every page/component when only this component requires it.
但是，如上所述，我只是将它包含在我的模板文件中：
However, as stated above, I simply cannon include it in my template file as such:
<template>
<div>
<h2>Upload Images</h2>
<form action="/file-upload" class="dropzone">
<div class="fallback">
<input name="file" type="file" multiple />
<input type="submit" value="upload" />
</div>
</form>
</div>
<script src="https://example.com/path/to/dropzone"></script>
</template>
<script>
export default {
data() {
return {}
}
}
</script>
<style>
</style>
如何只为一个组件包含外部脚本？
How can I include an external script for only one component?
推荐答案
您可以定义一个负责脚本加载的方法，并在挂载或创建的挂钩中调用它，如下所示： / p>
You can define a method that will be responsible for script loading and call it in the mounted or created hook like below:
<script>
export default {
data() {
return {}
},
methods: {
loadJs(url, callback) {
jQuery.ajax({
url: url,
dataType: 'script',
success: callback,
async: true
});
}
},
mounted() {
this.loadJs('url_to_someScript.js', function() {
//Stuff to do after someScript has loaded
});
}
}
</script>
