js异常处理
javascript同java一样，都有异常处理机制。在javascript中，也是用try...catch来进行异常处理。例如：<div class="dp-highlighter" style="font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; width: 694px; margin-left: 9px; line-height: 25px; text-align: left; padding: 1px;"><div class="bar"><div class="tools" style="font-weight: bold; padding: 3px; margin: 0px;">Js代码 http://zpball.iteye.com/images/icon_star.png
