我需要更新的时候在我的的setInterval 。该值是由的setInterval 正在执行函数返回。

I need to update the time in my setInterval. The value is returned by the function that setInterval is executing.

read_log（）; 返回一个整数

var loop = setInterval(function(){count = read_log();}, count);

这将返回计数是undefiend。所以，我需要得到计数并将其传递给的setInterval

This returns that count is undefiend. So I need to get the count and pass it to setInterval

推荐答案

如果您需要在每次调用 read_log（）后更改重复间隔，你不能使用的setInterval（） - 使用一类常重复。你需要使用的setTimeout ，所以你可以在每次更换周期：

If you need to change the repetition interval after each call to read_log(), you can't use setInterval() -- that uses a constent repetition. You need to use setTimeout, so you can change the period each time:

function call_read_log() {
    var count = read_log();
    setTimeout(call_read_log, count);
}
call_read_log();
