比较方便的控制fieldset的高度 <script language="JavaScript"> <!-- function admin_Size(num,objname) { var obj=document.getElementById(objname); if (parseInt(obj.style.height)+num>=50) { obj.style.height = parseInt(obj.style.height) + num; } if (num>0) { obj.width="90%"; } } //--> </script> <fieldset name="ArticleIntro" id="ArticleIntro" style="width:234px;height:100px;text-align:center;color:deeppink;"> <legend style="font-weight:800;">不是太熟悉</legend>就要去学习</fieldset> <a href="javascript:admin_Size(-50,'ArticleIntro')">减小</a> <a href="javascript:admin_Size(50,'ArticleIntro')">增加</a> [Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
