I have tried much to find solution of this problem but not able to figure out this.

Answer 1

When you put the Javascript in the href, the page also navigates to whatever the Javascript returns. In this case window.open returns a copy of the window object, which can't be navigated to.

You can solve this by moving the Javascript to onclick and having a href="#", or you can add a ;return false after the window.open, or put void() around the window.open,
