淡入/淡出功能的连续循环 [英] Continuous loop of fade in/out function

问题描述

我想在连续循环中运行以下函数，但我认为这对我有用，但并非如此，因为该函数只运行一次.我不确定问题出在方法，间隔还是我的代码上.我对此很陌生.

I have the following function that I would like to run on a continuous loop and I thought this would work for me, but not so because the function only runs once. I am not sure if the problem is with the method, the interval or my code. I am fairly new at this.

var c = $(".test p").length;    
setInterval(faderepeat(c),20000);

function faderepeat(c){     
  var i = 0;
  while (i<=c) {
var p = $(".para");
($(p[i]).delay(i*3000).fadeIn(2000).fadeOut(1000));
  i++;
    }
}

推荐答案

将setInterval调用更改为:

Change your setInterval call to:

setInterval( function() { faderepeat(c); }, 20000);

调用方式，该函数运行一次，而setInterval反复调用该函数的结果.

The way you are calling it, the function runs once and setInterval calls the result of the function repeatedly.
