如何停止setInterval,setTimeout
setInterval( "a() ",1000)启动后如何停止，还有递归的setTimeout,
如function a(){i++;setTimeout( "a() ",1000);},我想在按一下按钮后让他们停下来，该用什么语句，谢谢！
[解决办法]
function start()
{
var t = setTimeout( "start ",1000);
}
function stop()
{
clearTimeout(t)
}
[解决办法]
var t = setInterval( "start() ",1000);
clearInterval(t)
