From: Csaba Gabor on 21 Jun 2010 05:13 How can I most reliably detect when a link has been clicked to open in a new tab or to open in a new window? I have not found this question well adressed in the pages returned up my searches. I am doing some statistics gathering. In particular, I have some links that point to external websites (they are product links) and I would like to know when they are clicked, to verify against what the destination site reports. If they are clicked "normally", to open in the same window, it is no problem because one just adds an onclick handler to the link. All my onclick handler does is to send a request out via an embedded Iframe (so it can be logged by the server), and this request gets sent before the new page starts to load. However, the onclick does not fire when the link is opened in a new window or new tab (and that's how I always click my links because I don't want to lose the previous page). It is insufficient to detect oncontextmenu because the user might not activate the link (and I'd rather not have false positives). I don't need a bulletproof solution - I will be quite happy if the detection mechanisms works a good percentage of the time in recent versions of IE and FF. Regards, Csaba Gabor from Vienna

Only by looking at the window. Tabs are browser specific settings that are outside the reach of the DOM. =============== Perhaps you could measure the old and new page witdhs and compare those with the specified wondow.open() width? If the requested width is 20px, and the old and new witdh are both the same value and >250px, I would guess it is a tab. -- Evertjan. The Netherlands.

So, your counter works only if JS is enabled ? ! > All my onclick handler does is to send a request > out via an embedded Iframe (so it can be logged by the server), and > this request gets sent before the new page starts to load. If is only a question of clicks count, instead of onclick maybe onmousedown, onmouseup ? Or detect the no left-click on mouse down ? <a href="http://google.com" onmousedown="var e = event.wich||event.button; if(e>1) parent.myInvisibleIframe.location='myCountr.php?c='+this.href;" onclick="window.open('myCountr.php?c='+this.href,'view','width=300,height=300'); return false;">test with google</a> <iframe name="myInvisibleIframe" style="visibility:hidden;width:1px"></iframe> (not tested with IE) -- sm

Hi Evertjan, these links lead to external pages so that I don't have access to the DOM. The only thing that I can see is possible effects on the original page in which the link has been clicked. > Tabs are browser specific settings that are outside the reach of the DOM. > > =============== > > Perhaps you could measure the old and new page witdhs and compare those > with the specified wondow.open() width? > > If the requested width is 20px, and the old and new witdh are both the same > value and >250px, I would guess it is a tab. I like the brainstorming, but I don't think this is relevant here as there is no window.open() involved. Ie. a right click, open in new tab/window will open what is in href=..." in the relevant window, but not use a javascript window.open() to do so. > -- > Evertjan. > The Netherlands. > (Please change the x'es to dots in my emailaddress) |
