I have a website for which I have implemented livechat, when user clicks on livechat link it opens a new window that is fine. I want to do is when no operator is online then it should not open a new window when livechat link clicked instead it should redirect to the contact us page of the website in the same window in the currently opened tab, Is it possible? I do not know how is it possible, what I have tried is this , it redirects to this page but opens in a new window.
The problem is somewhere in the code around that. You need to call that code in the old window.
If you want to call it in the chat window, try:
href property instead:
window.location.href = 'http://mywebsite.com/index.php?route=information/contact';
