if (numb % 2 == 0) {
document.getElementById('img1').setAttribute('src', '/Uploads/images/1.jpg');
}

document.getElementById('img1').setAttribute('src', 'images/2.jpg');
}*/
//两张图片切换方法2 /*if (numb == 0) {
document.getElementById('img1').setAttribute('src', 'images/2.jpg');
numb = 1;
}
else {
document.getElementById('img1').setAttribute('src', '/Uploads/images/1.jpg');
numb = 0;
}*/
}
/图片轮换/多张 function imgfor() {
imgnumb++;
document.getElementById('img1').setAttribute('src', 'images/' + imgnumb + '.jpg');
if (imgnumb == 9) {
imgnumb = 0;
}

var clearid;
function clearfun() {
clearInterval(clearid);
}
clearid=setInterval(imgfor, 1000);
