用 JavaScript 计算时差 [英] Calculate Time Difference with JavaScript

问题描述

我有两个 HTML 输入框，需要计算 JavaScript onBlur 中的时间差(因为我需要实时)并将结果插入新的输入框.

格式示例:10:00 &12:30需要给我:02:30

谢谢！

解决方案

这是一种可能的解决方案:

function diff(start, end) {start = start.split(":");end = end.split(":");var startDate = new Date(0, 0, 0, start[0], start[1], 0);var endDate = new Date(0, 0, 0, end[0], end[1], 0);var diff = endDate.getTime() - startDate.getTime();var hours = Math.floor(diff/1000/60/60);差异 -= 小时 * 1000 * 60 * 60；var 分钟 = Math.floor(diff/1000/60);//如果使用 24 小时格式的时间选择器，请添加以下行以获取准确的小时数如果(小时<0)小时 = 小时 + 24；return (hours <= 9 ? "0" : "") + hours + ":" + (minutes <= 9 ? "0" : "") + 分钟；}

I have two HTML input boxes, that need to calculate the time difference in JavaScript onBlur (since I need it in real time) and insert the result to new input box.

Format example: 10:00 & 12:30 need to give me: 02:30

Thanks!

解决方案

Here is one possible solution:

function diff(start, end) {
    start = start.split(":");
    end = end.split(":");
    var startDate = new Date(0, 0, 0, start[0], start[1], 0);
    var endDate = new Date(0, 0, 0, end[0], end[1], 0);
    var diff = endDate.getTime() - startDate.getTime();
    var hours = Math.floor(diff / 1000 / 60 / 60);
    diff -= hours * 1000 * 60 * 60;
    var minutes = Math.floor(diff / 1000 / 60);

    // If using time pickers with 24 hours format, add the below line get exact hours
    if (hours < 0)
       hours = hours + 24;

    return (hours <= 9 ? "0" : "") + hours + ":" + (minutes <= 9 ? "0" : "") + minutes;
}
