晕,超简单的问题,改成这样就行了
function showme(obj1, obj2)
{//alert(moving);
if (moving)
return;
//moving = true;//实际上就是只要注掉这里就行了,多余
for(i=0;i<document.all.tags('td').length;i++)
if (document.all.tags('td')[i].className.indexOf('headtd') == 0)
document.all.tags('td')[i].className = 'headtd1';
obj2.className = 'headtd2';
moveme(obj1);
}
//还有,你的代码格式不好,所以,我把格式对齐后,1分钟就发现的了问题,试试看对不对
声明一下,你的代码没读完,我只针对你说的问题进行调试.测过后是你说的问题没了,但由于没详细去了解你的moving的作用,有没有带来新的问题,你自己应该清楚.
一句话就是,实际发现,连点两次每一贴会造成moving==true;而不能执行到后面的代码.发现这点后,要怎么改你应该很清楚了.
