//How to use the following function to display or hide the block:
//1. Please put your content what you want to display or hide into the 
//   "div" tag, and define the "div" as "<div class="collapse" id="yourElement"></div>".
//2. You want to use button or <a> link to display or hide the block, 
//    use like this in the button or <a> link:
//    want to expand:   onClick="javascript:setClassById('yourElement','expand');"
//    want to collapse: onClick="javascript:setClassById('yourElement','collapse');".
//3. The function will use the css.css to display or hide the block.
//4. The detail example please view the "/en/common/user/community/communityEdit.jsp".
