As we know we can associate some JavaScript function with am HTML button or an image and we used JavaScript on buttons images, same way can be follow with hyperlinks.  The code to associate some JavaScript function on Hyperlink will be as under.

Syntax for JavaScript associated with Hyperlink

<a href="" onClick="someFunctionName()"> Any thing else </a>

In this example we can change the text and the URL of a hyperlink. We can also change the target attribute for the hyperlink. The target attribute is by default set to "_self", which means that the link will open in the same window. By setting the target attribute to "_blank", the hyperlink will open in a new window as shown in below code.
