Internet Explorer cannot open the Internet site, the requested site is unavailable or cannot be found

I recently met a magical problem, colleagues in the development of the Google Browser, the implementation of a download function, testing is no problem, but the tester feedback that he could not download, reported abnormal. Pop-up box

Colleagues ran to discuss this problem with me, the author was at that time, so hurriedly find relevant information, after long time constantly test (at that time this project restart a particularly slow), finally fix!

The cause of the problem is: (url: Download path);

Before: window.open (url, ' _blank '), this method is not a problem in Google, Firefox and IE9 above, but IE8 and the following version will pop up the above image;

Modified: window.location = URL; tested Google, Firefox, IE9 and IE8 and the following versions are okay.

Summary: After development, it is best to try more than one browser at a time.

Internet Explorer cannot open the Internet site, the requested site is unavailable or cannot be found
