按钮不起作用并更改边框颜色

Question

I tried to code a little Firefox Extension but I don't get the Button in the popup working.我试图编写一个小的 Firefox 扩展，但我没有让弹出窗口中的按钮工作。 What should happen when you click the button is that the red border changes into a green one.当您单击该按钮时，红色边框会变为绿色边框。 I couldn't find the mistake.我找不到错误。

This is my manifest.json这是我的 manifest.json

{

  "manifest_version": 2,
  "name": "Testing",
  "version": "1.0",

  "description": "Testing",

  "icons": {
    "48": "icon.jpg"
  },

  "content_scripts": [
    {
      "matches": ["*://*.allee-abi20.de/*"],
      "js": ["ust.js"]
    }
  ],
    
  "permissions": [
    "activeTab",
    "contextMenus"
  ],
  
  "browser_action": {
        "default_icon": "icon.jpg",
        "default title": "Hallo",
        "default_popup": "view.html"
    }
}

Thats the view.html这就是view.html

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8"/>
        <link rel="stylesheet" href = "style.css" type="text/css"/> 
    </head>
    <body>
        <input type=text id="Kat"></input>
        <input type=text id="Ty"></input>
        <button id= "but">Klicken </button>     
    <script type="text/javascript" src="./popup.js"></script>   
    </body>
</html>

And thats the popup.js这就是 popup.js

document.body.style.border = "5px solid red";
var myLink = document.getElementById("But");
myLink.onclick = function(){
    document.body.style.border = "20px solid green";
}

Answer 1

只是一个关于大写的小语法问题：写but ，而不是But ，因为But是undefined 。
