How to refresh a pop-up window using javascript

I am using

window.open("http://something...")


to open a pop-up window which shows a PDF file with some report on it when certain ajax success gets hit. However my PDF file doesn't show the updated data every-time I open the pop-up window. If I manually hit the F5 or refresh the page it shows the updated data.
I tried something like this but to no avail.

window.open("http://something...").location.reload();


How can I refresh the pop-up window everytime it loads.

Answer

You can append a timestamp into the url to avoid the browser cache

var url = "http:/myurl/myFile.pdf?"+ Date.now();
window.open(url);

for older browsers that doesn't support Date.now() you can use new Date().getTime();
