Question

There is a link in my webpage, the link itself triggers a function that I could not modify, but I want to make the link, when clicked, also calls another JavaScript function at the same time or preferably after the first function is done. So one click to call two functions…could it be implemented? Thanks

<a title="Next Page" href="javascript:__doPostBack('Booklet1','V4504')">Next</a>

is the sample tag I want to modify, how could make it also call “myFunc” at the same time or preferably after _doPostBack is done.

P.S. the function parameter for _doPostBack such as V4504 is dynamically generated by the ASP user control. So I cannot simply treat it as a static function and bind it with another. I think I could only append some function to it? Unless I parse the whole page first and extract the function name with its current parameters…Since every time I click the link, the parameter such as V4504 changes its value….

Thanks!

You should be able to attach multiple event handlers to a single anchor tag, either with .onclick or .addEventListener('click', function)
