我想在此网页的末尾注入一个链接。
该链接将从一个记录循环到另一个记录,在链接末尾添加+1,因此当点击下一个链接时,该链接将从http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id=5425
更改为http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id=5426
等。
为此,我创建了一个带有iframe的HTML页面
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head><title>
</title><link href="includes/ls.css" rel="stylesheet" type="text/css" /></head>
<body bgcolor="#373536" >
<iframe
src="http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id=5425"
width="100%" height="500"
sandbox>
<p>
<a href="http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id=5425">
Fallback link for browsers that, unlikely, don't support frames
</a>
</p>
</body>
</html>
加载后的网页运行正常。但是,我不想使用iframe。所以我想创建一个Chrome扩展来注入代码。
我用它作为manifest.json:
{
"name": "Test",
"version": "0.0.1",
"manifest_version": 2,
"description": "This extension was created with the awesome extensionizr.com",
"homepage_url": "http://extensionizr.com",
"icons": {
"16": "icons/icon16.png",
"48": "icons/icon48.png",
"128": "icons/icon128.png"
},
"default_locale": "en",
"permissions": [
"http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id*"
],
"content_scripts": [
{
"matches": [
"http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id*"
],
"css": [
"src/inject/inject.css"
]
},
{
"matches": [
"http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id*"
],
"js": [
"src/inject/inject.js"
]
}
]
}
我的inject.js代码:
chrome.extension.sendMessage({}, function(response) {
var readyStateCheckInterval = setInterval(function() {
if (document.readyState === "complete") {
clearInterval(readyStateCheckInterval);
// ----------------------------------------------------------
// This part of the script triggers when page is done loading
console.log("Hello. This message was sent from scripts/inject.js");
// ----------------------------------------------------------
}
}, 10);
});
var c=5425;
var url="http://lcsyndicate.com.lb/web/popupGuide.aspx?Guide_Id=";
function f(){
document.getElementById("clicks").data = url+c;
c++;
}
var newlink = document.createElement('a');
newlink.innerHTML = 'Next>';
newlink.setAttribute('id','clicks');
newlink.setAttribute('title', 'Next>');
newlink.onclick = f;
newlink.setAttribute('onclick',"f()");
document.body.appendChild(newlink);
然而,当扩展程序运行时,我在页面上收到“未捕获的ReferenceError:f未定义”错误
我不知道如何修复它。我只是想添加一个从一个记录循环到另一个记录的链接。
感谢任何帮助
