Question

我正在尝试找出一种方法来计算同一字段中两个数字（24小时制）之间的差异

{
  xtype: "textfield",
  fieldLabel: "Monday",
  name: "mon1"
}, {
  xtype: "numberfield",
  fieldLabel: "Hours",
  name: "hoursMon1",
}

基本上，用户输入看起来像这样：

mon1 = 7.15-16.45

然后，我需要一个函数来计算hoursMon1字段中的差异（即“ 9.30”）。

由于程序的工作原理，我不能仅将输入分成2个字段并比较差异，所以有什么办法可以使我仅从1个字段执行类似的操作？

Answer 1

在console.log函数中获取时差

var time = "7.15-16.45".split("-");
console.log(msToTime(getMillsec(time[1])- getMillsec(time[0])))  //output 09-30


//get milliseconds
function getMillsec(ctime){
      var timeParts = ctime.split(".");
        return ((+timeParts[0] * (60000 * 60)) + (+timeParts[1] * 60000));
}

//convert millisecond to hour:min format
function msToTime(duration) {
    var milliseconds = parseInt((duration%1000)/100)
        , seconds = parseInt((duration/1000)%60)
        , minutes = parseInt((duration/(1000*60))%60)
        , hours = parseInt((duration/(1000*60*60))%24);

    hours = (hours < 10) ? "0" + hours : hours;
    minutes = (minutes < 10) ? "0" + minutes : minutes;
    seconds = (seconds < 10) ? "0" + seconds : seconds;

    return hours + "-" + minutes;
}
