javascript - 随机颜色字符串

Question

首先，这不是 Generate random string/characters in JavaScript 的重复项

我特别想要一个字符串更改为从绿色开始的随机颜色。我是用JS写的

function changeColor()
{
  var change;
  for( var i=0; i < 11; i++ )
  {
    change += script.charAt(Math.floor(Math.random() //Input ur suggestion here, I suspect it is the script variable and different colours
    script = document.getElementById('txt');
    script.style.color = "#33cc33";
  }
}

Answer 1

for 循环立即完成，您需要一个超时才能实际看到颜色变化，需要一个随机颜色生成器来生成颜色，然后放入递归 IIFE 就可以了:

var color = '#33cc33',
    elem  = document.getElementById('txt');

(function fn() {
    elem.style.color = color;
    setTimeout(function() {
        color = '#'+Math.floor(Math.random()*16777215).toString(16);
        fn();
    }, 500);
})();
