添加分钟到while循环

Question

我试图从用户结束时间添加30分钟，然后开启和显示时间

 function() {

            var toTime = new Date(result2);

            while (true) {

                var toTime30 = new Date(toTime.getTime() + toTime.getTimezoneOffset() *30 * 1000);
                var toTime60 = new Date(toTime30.getTime() + 30 * 60 * 1000);

                var addMin = toTime30 + "" + toTime60;


                    alert(addMin);
                    break;

            }

现在代码只在02:00到02:30之间添加第一个，我怎么能这样做呢？它会增加30分钟的时间吗？

更新

  var toTime = new Date(result2);

            while (true) {

                var iCount = 0;
                var toTime30 = new Date(toTime.getTime() + toTime.getTimezoneOffset() *30 * 1000);
                var toTime60 = new Date(toTime30.getTime() + 30 * 60 * 1000);

                var addMin = toTime30 + "" + toTime60 + (++iCount);


                alert(addMin);
                break;
            }

Answer 1

初始化之前不能使用变量。你应该做点什么

var iCount = 0;
var t = new Date();
var toTime30 = new Date(t.getTime() + t.getTimezoneOffset() * 30 * 1000);
console.log(t.getTime() + " - " + toTime30.getTime() + " - " +  (iCount++));
