当标签被更新时,我一直在尝试在谷歌页面中添加 iframe。iframe 显示更新后的 url 和标题。以编程方式显示 iframe 已插入,但我在页面上看不到 iframe。以下是我的内容脚本中的代码:
chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) { //onUpdated should fire when the selected tab is changed or a link is clicked
if (changeInfo.status == "complete") {
chrome.tabs.getSelected(null, function (tab) {
if (tab.url.indexOf(".google.") != -1) {
url = getRetailer(tab.url);
title = tab.title;
title = tab.title.replace(" - Google Search", "");
createiframe(url, title);
}
});
}
});
function createIframe(url, PN, uid) {
var iframe = document.createElement("iframe");
var div = document.createElement("div");
iframe.src = "url:" + url + 'title:" + PN ;
iframe.setAttribute("id", "cr_Iframe");
iframe.setAttribute("style", "position: fixed; z-index: 100001; left: 0pt; right: 0pt; top: 0pt; width: 100%; height: 42px; display: block;");
iframe.setAttribute("scrolling", "no");
iframe.setAttribute("frameborder", "0");
iframe.setAttribute("name", "cr_Iframe");
document.body.insertBefore(iframe, document.body.firstChild);
}
