Answer 1

onclick=""里面的内容可以串联吗？怎么写啊？<img id="tImg" src='<%=srcpath%>' width="18" height="16">onclick="document.all.tImg.src="ima/line_01_2.gif";
<div id="main" style="color:blue" onclick="document.all.child.style.display=(document.all.child.style.display=='none')?'':'none'">

Answer 2

i=01_2
eval("document.all.tImg.src='ima/line_"+i+".gif'";)

Answer 3

晕啊~..我是说~把
onclick="document.all.tImg.src="ima/line_01_2.gif";和onclick="document.all.child.style.display=(document.all.child.style.display=='none')?'':'none'">
怎么写在一起啊?
