jquery open window but only when window is not opened already; then show it in front of other windows?

问题

Would it be possible to have on click div open a window but only if that window hasn't opened before? Not modal but just a regular window with a certain size say 300x300.

I have this Jsfiddle but not fully working yet. The idea is to have 1 popup window and just push it in the front if its already opened.

You can use something like this:

$("#element_id").click(function(){
  window.open ("http://your-domain.com/your-url.html","my_window","menubar=1,resizable=1,width=350,height=250");
});

Basically every time you execute this window.open command, the same window will be utilized because of the same window name ("my_window" in this case)...

I hope this helps :)
