[英]button in popup.html not working
I have a popup.html, and what I thought was pretty simple listener event. 我有一个popup.html,我认为这是非常简单的监听器事件。
This is my popup.html: 这是我的popup.html:
<!DOCTYPE html>
<html>
<body>
<button id="button">Starting Now</button>
<script>
function blah(){
alert("blah");
}
$(document).ready(function(){
document.getElementById('button').addEventListener("click", blah);
});
</script>
</body>
</html>
There's no alert when I press the button; 当我按下按钮时没有警报; what am I doing wrong?
我究竟做错了什么?
Your code is okay from normal web-page point of view but from the guidelines of Chrome Extension Development you need to check Content Security Policy (CSP) which says: 从正常的网页角度来看,您的代码是可以的,但是根据Chrome扩展程序开发的准则,您需要检查内容安全政策(CSP) ,其中指出:
Inline JavaScript will not be executed.
内联JavaScript将不会执行。 This restriction bans both inline
<script>
blocks and inline event handlers (eg<button onclick="...">
).此限制禁止内联
<script>
块和内联事件处理程序(例如<button onclick="...">
)。
So, what you can do to test your code is place the script code in a separate .js
file and then refer it in your html. 因此,您可以将脚本代码放在单独的
.js
文件中,然后在html中进行引用,以测试代码。
As suggested by Xan in comments about the usage of alert()
: 正如Xan在有关
alert()
用法的评论中所建议的那样:
In place of alert()
you can use simple console.log()
if the purpose is only to test the button click or else if you really want pop-up alert like thing then create a modal dialog. 如果目的只是为了测试按钮单击,或者如果您确实想要像这样的弹出警报,然后创建一个模式对话框,则可以使用简单的
console.log()
代替alert()
。
Just for reference only ( Probably OP is already aware of it though ): 仅供参考 ( 虽然OP可能已经知道了 ):
Since you are using jQuery
check this guideline also about loading jQuery or other libraries . 由于您使用的是
jQuery
请同时检查有关加载jQuery或其他库的本指南 。
