分享初学javascript,请教怎样用javascript控制一段HTML是否执行
我想用javascript做一个选择，条件为a,b
if(a)
HTML代码如下：
<a href="../Visit/QueryMenu.aspx" target="_top" onClick="MM_nbGroup('down','group1','menu_out_v','../Common/Img/menu_over_v.jpg',1)" onMouseOver="MM_nbGroup('over','menu_out_v','../Common/Img/menu_over_v.jpg','',1)" onMouseOut="MM_nbGroup('out')"><img src="../Common/Img/menu_over_v.jpg" alt="" name="menu_out_v" width="135" height="30" border="0" onload="MM_nbGroup('init','group1','menu_out_v','../Common/Img/menu_out_v.jpg',1)"></a>
else
HTML代码如下：
<img src="../Common/Img/menu_over_v.jpg" alt="" name="menu_out_v" width="135" height="30" border="0" onload="MM_nbGroup('init','group1','menu_out_v','../Common/Img/menu_out_v.jpg',1)">
我怎样去写这个控制结构？

必须那样写吗？那些带引号的地方如何转义，HTML代码好长啊，写起来累死我
