I want to author an anchor tag that executes some JavaScript and then proceeds to go wherever the href was taking it. Invoking a function that executes my JavaScript and then sets window.location or top.location to the href location doesn't work for me.
So, imagine I have an element with id "Foo" on the page. I want to author an anchor similar to:
<a href="#Foo" onclick="runMyFunction(); return false;">Do it!</a> When this is clicked, I want to execute runMyFunction and then jump the page to #Foo (not cause a reload - using top.location would cause it to reload the page).
Suggestions? I am happy to use jQuery if it can help here...

How to make this a tag working with href and onClick? The default behavior of the <a> tag's onclick and href properties are to execute the onclick , then follow the href as long as the onclick doesn't return false , canceling the event (or the event hasn't been prevented).
Using onclick Event: The onclick event attribute works when the user click on the button. When mouse clicked on the button then the button acts like a link and redirect page into the given location. Using button tag inside <a> tag: This method create a button inside anchor tag.
If the link should only change the location if the function run is successful, then do onclick="return runMyFunction();" and in the function you would return true or false. If you just want to run the function, and then let the anchor tag do its job, simply remove the return false statement.
I would generally recommend using element. attachEvent (IE) or element. addEventListener (other browsers) over setting the onclick event directly as the latter will replace any existing event handlers for that element. attachEvent / addEventListening allow multiple event handlers to be created.
Just return true instead?
The return value from the onClick code is what determines whether the link's inherent clicked action is processed or not - returning false means that it isn't processed, but if you return true then the browser will proceed to process it after your function returns and go to the proper anchor.
