In JavaScript, window.open method can be used to open link in a new window. This method can be used to open a new window when a page is opened. However this method of opening a pop-up window will be blocked by recent browsers as part of their pop-up advertisement blocking feature.

Place the following code in your HTML file.

<script type="text/javascript"><!--
window.open('http://techpulp.com');
//--></script>
