调用方法,主方法
function dateDiff(date1, date2){
var type1 = typeof date1, type2 = typeof date2;
if(type1 == 'string') {
date1 = stringToTime(date1);
}else if(date1.getTime) {
date1 = date1.getTime();
}
if(type2 == 'string') {
date2 = stringToTime(date2);
} else if(date2.getTime) {
date2 = date2.getTime();
}
return (date1 - date2) / 1000;//结果是秒
}
字符串转成Time(dateDiff)所需方法
function stringToTime(string){
var f = string.split(' ', 2);
var d = (f[0] ? f[0] : '').split('-', 3);
var t = (f[1] ? f[1] : '').split(':', 3);
return (new Date(
parseInt(d[0], 10) || null,
(parseInt(d[1], 10) || 1)-1,
parseInt(d[2], 10) || null,
parseInt(t[0], 10) || null,
parseInt(t[1], 10) || null,
parseInt(t[2], 10) || null
)).getTime();
}
获取相差时间转换成天,小时,分钟,秒
var days = Math.floor(time / 60 / 60 / 24),
hours = Math.floor(time / 60 / 60 - ( days * 24 ));
minutes = Math.floor(time / 60 - (hours * 60) - (days * 24 * 60));
seconds = Math.floor(time - (minutes * 60) - (hours * 60 * 60) - (days * 24 * 60 * 60));
