有人可以向我解释为什么window.onload在aspx中工作正常,但在xhtml中没有?
这个window.onload示例在aspx中工作正常:
<script type="text/javascript">
//<![CDATA[
//handles the collapse of submenu items on navigation side menu
function toggle() {
document.getElementById('node4').style.display = '';
}
window.onload = toggle;
//]]>
</script>
但是这个window.onload示例在XHTML 1.0 strict中不起作用。 (当加载页面时,它不会立即触发countDownClock):
<script type="text/javascript">
//<![CDATA[
//handles the collapse of submenu items on navigation side menu
function countDownClock() {
today = new Date();
openingDay = new Date();
openingDay.setMonth(2, 23);
(today > openingDay) ? openingDay.setFullYear(2013) : openingDay.setFullYear();
openingDay.setHours(9, 0, 0, 0);
document.getElementById("mallclock").dayNow.value = showDate(today);
document.getElementById("mallclock").timeNow.value = showTime(today);
var daysLeft = dayDiff(today, openingDay);
var hoursLeft = hoursDiff(today, openingDay);
var minutesLeft = minutesDiff(today, openingDay);
daysLeft = ((hoursLeft - 24) >= 0) ? daysLeft + (hoursLeft / 24) : daysLeft;
hoursLeft = ((hoursLeft - 24) >= 0) ? hoursLeft - ((hoursLeft / 24) * 24) : hoursLeft;
hoursLeft = ((minutesLeft - 60) >= 0) ? hoursLeft + (minutesLeft / 60) : hoursLeft;
minutesLeft = ((minutesLeft - 60) >= 0) ? minutesLeft - ((minutesLeft / 60) * 60) : minutesLeft;
document.getElementById("mallclock").days.value = daysLeft;
document.getElementById("mallclock").hours.value = hoursLeft;
document.getElementById("mallclock").minutes.value = minutesLeft;
}
window.onload = countDownClock;
//]]>
</script>
它只会触发body事件,该事件设置为在1分钟后显示countDownClock
<body onload = "setInterval('countDownClock()', 60000)">
答案 0 :(得分:2)
啊哈,编辑完全不同。
一个页面只能有load
个事件的一个处理程序,因此如果您使用window.onload
添加一个,并使用body onload
属性添加另一个,则只有其中一个可以使用。
将两个动作放在同一个处理程序中:
window.onload = function(){
countDownClock();
window.setInterval(countDownClock, 60000);
};
