Javascript RegEx: validate time
提问by Sri Reddy
I have a stopwatch variable that can get value in the following format:
HH:MM:SSmost of the time. 'HH'can go past 24 hours - basically any valid number.
我有一个秒表变量，可以按以下格式获取值：
HH:MM:SS大部分时间。'HH'可以超过 24 小时 - 基本上任何有效数字。
I am not that good with this regex thingy, but was able to write something that is good for most part but fails to validate if the hour is single digit. Ex. below regex pass the time 1:10:09, though it is invalid. valid hour part should be 01.
我对这个正则表达式不太好，但能够写出大部分都很好的东西，但无法验证小时是否是个位数。前任。下面的正则表达式通过时间1:10:09，虽然它是无效的。有效小时部分应该是01.
//var stopWatchTime = '02:10:09'; //Valid
//var stopWatchTime = '00:10:09'; //Valid
//var stopWatchTime = '1234:10:09'; //Valid
//var stopWatchTime = ':10:09'; //Invalid
//var stopWatchTime = 'ax:10:09'; //Invalid
var stopWatchTime = '1:10:09'; //Invalid, should be 01:10:09.
if(!stopWatchTime .match(/^\d+:\d{2}:\d{2}$/)){
alert('invalid time- ' + stopWatchTime);
}
else{
alert('valid time - ' + stopWatchTime);
}
What should I change in the regex to say it should check for any number but should have 2 digits or more in hour part?
我应该在正则表达式中更改什么以表示它应该检查任何数字，但在小时部分应该有 2 位或更多位？

/^\d{2,}:\d{2}:\d{2}$/
Change the + to a {2,} to allow it to have two or more characters
将 + 更改为 {2,} 以允许它有两个或更多字符
If you want to see the things that matches and doesn't match you can play with it here http://regexr.com?31fu4

EDIT: Also if you only want to match up to 59 in the hours/minutes part use
编辑：此外，如果您只想在小时/分钟部分中匹配多达 59 个，请使用
^\d{2,}:(?:[0-5]\d):(?:[0-5]\d)$

// use this function to validate time in HH:mm formate
function validate_time(time){
var a=true;
var time_arr=time.split(":");
if(time_arr.length!=2){
a=false;
}else{
if(isNaN(time_arr[0]) || isNaN(time_arr[1])){
a=false;
}
if(time_arr[0]<24 && time_arr[1]<60)
{
} else{
a=false;
}
}
return a;
}

Another solution could be:
另一种解决方案可能是：
$('#input-horaIni, #input-horaFin').blur(function () {
var validTime = $(this).val().match(/^([01]?[0-9]|2[0-3]):[0-5][0-9]$/);
if (!validTime) {
$(this).val('').focus().css('background', '#fdd');
} else {
$(this).css('background', 'transparent');
}
});
This works for me... Based on page: http://www.mkyong.com/regular-expressions
这对我有用......基于页面：http: //www.mkyong.com/regular-expressions

Here is my answer for this validation!
这是我对此验证的回答！
function checkTimes(val){
val=new String(val);
if(val.length!=5){
return false;
}
else{
var hour=val.substring(0,2);
var min=val.substring(3,5);
if(val.substring(2,3)!==":") return false;
if(isNaN(hour)) return false;
if(isNaN(min)) return false;
if(parseInt(hour)<24){
if(parseInt(min)<60){
return true;
}
else return false;
}else return false;
}
}
You can extend my answer for 8chars...
