获取浏览器选项卡索引/ ID [英] Get Browser Tab Index/Id

问题描述

因此​​，在最新的浏览器有标签的功能，有没有办法让标签指数？

So in most current browsers there is the feature of Tabs, is there a way to get the Tab index?

所以选项卡1已经在www.google.com开业和Tab 2已经在www.google.com它打开了，有没有办法来识别标签指数是什么？

so Tab 1 has www.google.com opened in it and Tab 2 has www.google.com opened in it, is there a way to identify what the Tab index is?

伪code：

if($tab == 2) {
  alert "Tab 2 is active\n";
}

if($tab == 1) {
  alert "Please use Tab 2 as this is Tab 1\n";
}

有趣，因为一切我搜索有关的标签是关系到网页本身的选项卡索引，叹了口气......

Funny as everything I search for about tabs is related to the tab index of the webpage itself, sigh...

Google does this with JavaScript and Cookies. For every instance of the page opened, increment a cookie counter. If the counter > 1, use AJAX to display an error message. Also, prohibit the page from functioning if cookies or JavaScript is disabled.
