onclick或内联脚本在扩展程序中不起作用 [英] onclick or inline script isn't working in extension
问题描述
这似乎是最简单的操作，但它不起作用.在普通的浏览器中，.html和.js文件可以完美运行，但是在Chrome/Firefox扩展程序中，onClick函数无法执行应有的功能.
This seems to be the easiest thing to do, but it's just not working. In a normal browser the .html and .js files works perfectly, but in the Chrome/Firefox extension the onClick function is not performing what it's supposed to do.
.js文件:
function hellYeah(text) {
document.getElementById("text-holder").innerHTML = text;
}
.html文件:
<!doctype html>
<html>
<head>
<title>
Getting Started Extension's Popup
</title>
<script src="popup.js"></script>
</head>
<body>
<div id="text-holder">
ha
</div>
<br />
<a onClick=hellYeah("xxx")>
hyhy
</a>
</body>
</html>
因此，基本上，一旦用户单击"hyhy"，"ha"，应更改为"xxx".再说一遍-它在浏览器中完美运行，但在扩展程序中不起作用.你知道为什么吗?以防万一我还要在下面附加manifest.json.
So basically once the user clicks "hyhy", "ha" should change into "xxx". And again - it works perfectly in the browser but does not work in the extension. Do you know why? Just in case I'm attaching the manifest.json below as well.
manifest.json:
manifest.json:
{
"name": "My First Extension",
"version": "1.0",
"manifest_version": 2,
"description": "The first extension that I made.",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"permissions": [
"http://api.flickr.com/"
]
}
推荐答案
Chrome扩展程序不允许您使用内联JavaScript(文档).
Chrome Extensions don't allow you to have inline JavaScript (documentation).
The same goes for Firefox WebExtensions (documentation).
您将必须执行以下操作:
You are going to have to do something similar to this:
为链接分配一个ID(<a onClick=hellYeah("xxx")>变为<a id="link">)，然后使用 addEventListener 绑定事件.将以下内容放入您的popup.js文件:
Assign an ID to the link (<a onClick=hellYeah("xxx")> becomes <a id="link">), and use addEventListener to bind the event. Put the following in your popup.js file:
document.addEventListener('DOMContentLoaded', function() {
var link = document.getElementById('link');
// onClick's logic below:
link.addEventListener('click', function() {
hellYeah('xxx');
});
});
popup.js应该作为单独的脚本文件加载:
popup.js should be loaded as a separate script file:
<script src="popup.js"></script>
