function mov_left() {
if (parseInt(document.getElementById('fold').style.left, 10) == 430) {
clearInterval(animel);
}
document.getElementById('fold').style.left = (parseInt(document.getElementById('fold').style.left, 10) - 10) + 'px';
}
animel = setInterval('mov_left()', 100);
This is the code I'm trying to use to move a <div>
containing 2 images so they can display the two images one at a time. However, the image just keeps moving to the left ignoring the if
statement in the function.
Help please.
well I've fiddled with it, not really much change but I know this works:
function mov_left() {
var el = document.getElementById('fold');
if (parseInt(el.style.left, 10) == 430) {
clearInterval(animel);
}
el.style.left = (parseInt(el.style.left, 10) - 10) + 'px';
}
animel = setInterval(function () {mov_left(); }, 100);

如果未设置element的左css属性,则element.style.left将返回一个空字符串,而parseInt将返回NAN。
