肯定是用onmouseover事件. 请参考下面例程 <DIV> <P>Move the mouse pointer into the text area to fire the onmouseover event. Move it out to clear the text. <TEXTAREA NAME=txtMouseTrack onmouseover="this.value='onmouseover fired'" onmouseout="this.value=''"> </TEXTAREA> </DIV> 还有多种实现方式,如: var str1="..."; 用onmouseover事件,在js中, str1=str1+"...";从而显示全部内容.
