JavaScript-SetInterval无法正常运行

问题描述

我得到了这段脚本(在本地运行):

I got this piece of script (runned locally):

<script>

last = 0;

function uploadnew(){

var randomnumber=Math.floor(Math.random()*6);
if(randomnumber != last){
    document.forms['f'+randomnumber].submit();
} else { uploadnew(); }

}

setInterval (uploadnew(), 1000*60*5);

</script>

但是似乎setInterval不起作用/发送表单函数不起作用...

But it seems that setInterval is not working / send form function doesn't work...

任何帮助将不胜感激！

谢谢！

推荐答案

您需要致电 setInterval() 在函数上不带括号，例如:

You need to call setInterval() without parenthesis on your function, like this:

setInterval(uploadnew, 1000*60*5);

使用括号立即将其称为 并分配结果( undefined )以一定的间隔运行，而不是使用括号来传递函数本身，而不是函数的结果.

Using parenthesis you're calling it immediately and assigning the result (undefined) to be run on an interval, instead don't use parenthesis to pass the function itself, not the result of the function.
