如何在浏览器打开新标签页时捕获目标 url

Question

Is it possible to catch the attribute of hyperlink with JavaScript or Jquery on browsers open new tab event?

lets say I have a hyperlink <a href="http://example.com/something">MyLink</a> and using right click on link and opening new tab should alert first " http://example.com "

Answer 1

I think this is only possible with writing a browser extension. You cant control this type of things with JavaScript.

Answer 2

Ok, so this is the best that I can come up with but it ain't pretty.

Have all the links on the page point to another page (we'll call it redir.html). redir.html is passed a parameter via the URL that defines what page it should then open, like redir.html?page=www.example.com/something . redir.html then executes whatever JavaScript you want, perhaps only if it was opened in a new tab/window. This can be detected by checking to see if window.history.length === 1 .

redir.html:

<script>
function getParameter(param) {
            var val = document.URL;
            var url = val.substr(val.indexOf(param))  
            var n=url.replace(param+"=","");
            return n;
}
var page = getParameter("page");
if(window.history.length === 1)
{
    alert("I opened in a new tab or window");
}

window.location.href = page;
</script>

Example anchor tag on source page:

<a href="redir.html?page=http://example.com/something">My link</a>

(I got the getParameter function from this SO post .)
