How to call JavaScript function instead of href in HTML

Question

I have some mockup in HTML

Answer 1

Your should also separate the javascript from the HTML.
HTML:

javascript:

myLink = document.getElementById('function-click');
myLink.onclick = ShowOld(2367,146986,2);

Just make sure the last line in the ShowOld function is:

return false;

as this will stop the link from opening in the browser.
