i need jquery to work on a browser locally. how do i know if it is installed and how do i install it ?
my question is specific to being able to run this code:
onmouseover="evt.target.setAttribute('opacity', '0.5'); $('#someDiv').show();"
onmouseout="evt.target.setAttribute('opacity', '1'); $('#someDiv').hide();"
If you are going to include jQuery locally, as per Robert’s suggestion, you will first have to download it from here: http://code.jquery.com/jquery-1.4.2.min.js
