你的時(shí)間字符串在數(shù)組中嗎？
你可以使用這樣的東西：
var hours = 0;
var minutes = 0;
var seconds = 0;
var sum = '';
var myArray = ["01:40:40","03:50:50"];
var myFunction = function(){
for(var i in myArray){
hours += parseInt(myArray[i].substring(0, 2))
minutes += parseInt(myArray[i].substring(3, 5))
seconds += parseInt(myArray[i].substring(6))
}
if(seconds > 59){
minutes += parseInt(seconds / 60);
seconds = parseInt(seconds % 60);
}
if(minutes > 59){
hours += parseInt(minutes / 60);
minutes = parseInt(minutes % 60);
}
sum = hours + ":" + minutes + ":" + seconds;
console.log(sum);
}
myFunction();
如果您有任何其他問題，請隨時(shí)詢問。

**This may also work :**
var time1 = "01:00:00";
var time2 = "00:30:00";
var time3 = "00:30:00";
var hour=0;
var minute=0;
var second=0;
var splitTime1= time1.split(':');
var splitTime2= time2.split(':');
var splitTime3= time3.split(':');
hour = parseInt(splitTime1[0])+parseInt(splitTime2[0])+parseInt(splitTime3[0]);
minute = parseInt(splitTime1[1])+parseInt(splitTime2[1])+parseInt(splitTime3[1]);
hour = hour + minute/60;
minute = minute%60;
second = parseInt(splitTime1[2])+parseInt(splitTime2[2])+parseInt(splitTime3[2]);
minute = minute + second/60;
second = second%60;
alert('sum of above time= '+hour+':'+minute+':'+second);
