定時(shí)器沒(méi)有你那么寫(xiě)的吧。里面是一個(gè)匿名回調(diào)函數(shù)
oimg[i].onmouseover=function(){
?? ??? ??? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ??? ??? ?clearInterval(timer);
?? ??? ??? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ??? ??? ?timer=setInterval(
?? ??? ??? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ??? ??? ?start(400);
?? ??? ??? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ??? ??? ?},30);
仔細(xì)看，{} 明顯的嵌套不對(duì)
