我下面的脚本在 ie 中工作,但在 Firefox 中我得到:
Mon, July 16th 2012 //this is ok
NaN:NaN:NaN (UTC +2) //but the time???
...
var weekdaystxt = ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"];
function showLocalTime(container, servermode, offsetMinutes, displayversion) {
if (!document.getElementById || !document.getElementById(container)) return
this.container = document.getElementById(container)
this.displayversion = displayversion
var servertimestring = (servermode == "server-php") ? '<? print date("D, F jS Y H:i:s", time())?>' : (servermode == "server-ssi") ? '<!--#config timefmt="%B %d, %Y %H:%M:%S"--><!--#echo var="DATE_LOCAL" -->' : '<%= Now() %>'
this.localtime = this.serverdate = new Date(servertimestring)
this.localtime.setTime(this.serverdate.getTime() + offsetMinutes * 60 * 1000) //add user offset to server time
this.updateTime()
this.updateContainer()
}
showLocalTime.prototype.updateTime = function() {
var thisobj = this
this.localtime.setSeconds(this.localtime.getSeconds() + 1)
setTimeout(function() {
thisobj.updateTime()
}, 1000) //update time every second
}
showLocalTime.prototype.updateContainer = function() {
var thisobj = this
if (this.displayversion == "long") this.container.innerHTML = '<? print date("D, F jS Y")?>'
else {
var hour = this.localtime.getHours()
var minutes = this.localtime.getMinutes()
var seconds = this.localtime.getSeconds()
var ampm = (hour >= 12) ? "PM" : "AM"
var dayofweek = weekdaystxt[this.localtime.getDay()]
this.container.innerHTML = formatField(hour, 1) + ":" + formatField(minutes) + ":" + formatField(seconds) + " (UTC +2)"
}
setTimeout(function() {
thisobj.updateContainer()
}, 1000) //update container every second
}
function formatField(num, isHour) {
if (typeof isHour != "undefined") { //if this is the hour field
var hour = (num > 24) ? num - 24 : num
return (hour == 0) ? 24 : hour
}
return (num <= 9) ? "0" + num : num //if this is minute or sec field
}
