我无法从我的内容脚本中获得响应以显示在我的popup.html中.当此代码运行并单击"查找"按钮时,"Hello from response!" 打印,但变量响应打印为未定义.最终目标是将当前选项卡的DOM放入我的脚本文件中,以便我可以解析它.我正在使用单个时间消息到内容脚本来获取DOM,但它没有被返回并且显示为未定义.我正在寻找任何可能的帮助.谢谢.
popup.html:
<!DOCTYPE html>
<html>
<body>
<head>
<script src="script.js"></script>
</head>
<form >
Find: <input id="find" type="text"> </input>
</form>
<button id="find_button"> Find </button>
</body>
</html>
manifest.json的:
{
"name": "Enhanced Find",
"version": "1.0",
"manifest_version": 2,
"description": "Ctrl+F, but better",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"permissions": [
"tabs",
"*://*/*"
],
"background":{
"scripts": ["script.js"],
"persistent": true
},
"content_scripts":[
{
"matches": ["http://*/*", "https://*/*"],
"js": ["content_script.js"],
"run_at": "document_end"
}
]
}
的script.js:
var bkg = chrome.extension.getBackgroundPage();
function eventHandler(){
var input = …javascript message google-chrome google-chrome-extension content-script
