[英]Get current url when changing tabs in xul in firefox
I am trying to get the current URL after changing tabs in Firefox. 我正在尝试在Firefox中更改选项卡后获取当前URL。 Is it possible? 可能吗?
A complete example that logs the current URL to the Error Console each time a new tab is selected: 一个完整的示例,每次选择一个新选项卡时,会将当前URL记录到错误控制台:
function LOG(msg) {
var consoleService = Components.classes["@mozilla.org/consoleservice;1"]
.getService(Components.interfaces.nsIConsoleService);
consoleService.logStringMessage(msg);
}
function onTabChange() {
var href = gBrowser.contentDocument.location.href;
LOG(href);
}
window.addEventListener("load", function(e) {
gBrowser.tabContainer.addEventListener("TabSelect", onTabChange, false);
}, false);
window.addEventListener("unload", function(e) {
gBrowser.tabContainer.removeEventListener("TabSelect", onTabChange, false);
}, false);
