如何点击Chrome扩展程序中的按钮

我只想设置一个简单的Chrome扩展程序,只需在点击扩展程序按钮后单击某个元素即可。

我对此进行了一些研究,我找不到一个简单的答案,说明如何点击,其他人都有非常精细的代码,我无法理解,也不知道是否有必要。我的意思是,每当我搜索“点击”时,我发现一个比我的级别更高级的问题。

(我即将从这个扩展中赚取很多钱,所以请你帮助一个兄弟;)

使用我所看到的,我已将代码拼凑在一起:

popup.js:

var evt = document.createEvent ("HTMLEvents");
evt.initEvent ("click", true, true);

document.getElementById('product-addtocart-button').dispatchEvent (evt);

的manifest.json:

{
  "manifest_version": 2,

  "name": "Shoe BOT",
  "description": "This extension shows a Google Image search result for the current page",
  "version": "1.0",

  "browser_action": {
    "default_icon": "icon.png",
    "default_popup": "popup.html"
  },
  "permissions": [
    "activeTab",
    "https://shop.adidas.ae/en/"
  ]
}

popup.html:

<!doctype html>
<!--
 This page is shown when the extension button is clicked, because the
 "browser_action" field in manifest.json contains the "default_popup" key with
 value "popup.html".
 -->
<html>
  <head>
    <title>Getting Started Extension's Popup</title>
    <style>
      body {

      }
      #status {

      }
    </style>

    <script src="popup.js"></script>
  </head>
  <body>
    <!--<div id="status"></div>
    <img id="image-result" hidden>-->
  </body>
</html>

目前尚不清楚您使用document.createEvent()的原因。该接口已弃用。要创建活动,您应该使用event constructors。但是,对于HTML元素上的通用click event,您只需使用click() method而无需实际构建事件。

当您点击id="product-addtocart-button"按钮时,一个简单,完整的Chrome扩展程序会点击content script点按browser_action按钮,这将是:

background.js

chrome.browserAction.onClicked.addListener(function(tab) {
    chrome.tabs.executeScript(tab.id,{
        code: "document.getElementById('product-addtocart-button').click();"
    });
});

的manifest.json

{
    "description": "Click a button with ID=product-addtocart-button",
    "manifest_version": 2,
    "name": "click-product-addtocart-button",
    "version": "0.1",

    "permissions": [
        "activeTab"
    ],

    "background": {
        "scripts": [
            "background.js"
        ]
    },

    "browser_action": {
        "default_icon": {
            "32": "myIcon.png"
        },
        "default_title": "Click product-addtocart-button"
    }
}
