setInterval(function()，time)在运行时更改时间 [英] setInterval(function(),time) change time on runtime

问题描述

我想在代码运行时更改setInterval函数的时间.

I want to change setInterval function time when my code is running.

我尝试

<script type="text/javascript">
        $(function () {
            var timer;
            function come() { alert("here"); }
            timer = setInterval(come, 0);
            clearInterval(timer);
            timer = setInterval(come, 10000);
        });
    </script>

第一个SetInterval不起作用！

First SetInterval does not work!

推荐答案

您正在清除下一行的间隔，因此第一个间隔将不起作用，因为它会立即被清除:

You're clearing the interval on the next line, so the first one wont work, as it gets cleared right away :

        timer = setInterval(come, 0);
        clearInterval(timer);
        timer = setInterval(come, 10000);

而且，正如gdoron所说，设置无间隔时间并不是真正有效，也不是一个好主意，请改用setTimeout，或者在不需要延迟的情况下直接运行该函数.

Also, as gdoron says, setting a interval of nothing isn't really valid, and not a really good idea either, use setTimeout instead, or just run the function outright if no delay is needed.

        come();
        clearInterval(timer);
        timer = setInterval(come, 10000);
