Question

怎么在jquery中判断页面文本框输入的的2个时间大小，当起始时间大于结束时间时，提交按钮不可用。

Answer 1

大概意思这样，如果需要在离开文本框时就开始判断，还需要在文本框txt1和txt2的onblur增加一下类似代码
jQuery(function($) {
if(DateDiff("d",$("#txt1").val(),$("#txt2").val()))>0{
$(”#test”).attr(’disabled’,false);
}else{
$(”#test”).attr(’disabled’,true);
}
});

function DateDiff(interval,date1,date2)
{
var TimeCom1 = new TimeCom(date1);
var TimeCom2 = new TimeCom(date2);
var result;
switch(String(interval).toLowerCase())
{
case "y":
case "year":
result = TimeCom1.year-TimeCom2.year;
break;
case "m":
case "month":
result = (TimeCom1.year-TimeCom2.year)*12+(TimeCom1.month-TimeCom2.month);
break;
case "d":
case "day":
result = Math.round((Date.UTC(TimeCom1.year,TimeCom1.month-1,TimeCom1.day)-Date.UTC(TimeCom2.year,TimeCom2.month-1,TimeCom2.day))/(1000*60*60*24));
break;
case "h":
case "hour":
result = Math.round((Date.UTC(TimeCom1.year,TimeCom1.month-1,TimeCom1.day,TimeCom1.hour)-Date.UTC(TimeCom2.year,TimeCom2.month-1,TimeCom2.day,TimeCom2.hour))/(1000*60*60));
break;
case "min":
case "minute":
result = Math.round((Date.UTC(TimeCom1.year,TimeCom1.month-1,TimeCom1.day,TimeCom1.hour,TimeCom1.minute)-Date.UTC(TimeCom2.year,TimeCom2.month-1,TimeCom2.day,TimeCom2.hour,TimeCom2.minute))/(1000*60));
break;
case "s":
case "second":
result = Math.round((Date.UTC(TimeCom1.year,TimeCom1.month-1,TimeCom1.day,TimeCom1.hour,TimeCom1.minute,TimeCom1.second)-Date.UTC(TimeCom2.year,TimeCom2.month-1,TimeCom2.day,TimeCom2.hour,TimeCom2.minute,TimeCom2.second))/1000);
break;
case "ms":
case "msecond":
result = Date.UTC(TimeCom1.year,TimeCom1.month-1,TimeCom1.day,TimeCom1.hour,TimeCom1.minute,TimeCom1.second,TimeCom1.msecond)-Date.UTC(TimeCom2.year,TimeCom2.month-1,TimeCom2.day,TimeCom2.hour,TimeCom2.minute,TimeCom2.second,TimeCom1.msecond);
break;
case "w":
case "week":
result = Math.round((Date.UTC(TimeCom1.year,TimeCom1.month-1,TimeCom1.day)-Date.UTC(TimeCom2.year,TimeCom2.month-1,TimeCom2.day))/(1000*60*60*24)) % 7;
break;
default:
result = "invalid";
}
return(result);
}

//alert(compareDate(''2004-12-01'',''2004-05-02'''));
//目前只支持年－月－日这样的格式
function compareDate(DateOne,DateTwo)
{
var OneMonth = DateOne.substring(5,DateOne.lastIndexOf ("-"));
var OneDay = DateOne.substring(DateOne.length,DateOne.lastIndexOf ("-")+1);
var OneYear = DateOne.substring(0,DateOne.indexOf ("-"));

var TwoMonth = DateTwo.substring(5,DateTwo.lastIndexOf ("-"));
var TwoDay = DateTwo.substring(DateTwo.length,DateTwo.lastIndexOf ("-")+1);
var TwoYear = DateTwo.substring(0,DateTwo.indexOf ("-"));

if (Date.parse(OneMonth+"/"+OneDay+"/"+OneYear) <= Date.parse(TwoMonth+"/"+TwoDay+"/"+TwoYear))
return true;
else
return false;
}
