如何使Javascript中的每个字母在文本中不同的随机颜色 [英] How to make each letter in text a different random color in Javascript

问题描述

我想让一行文字中的每一个字母都是不同的随机颜色。我只能似乎使它这样做，当我使用.hover，但我想要它立即做的动作（一旦页面加载）。请帮忙。我也想知道如果有人知道如何只是设置不同的颜色在每个字母（设置颜色）与CSS或Javascript，因为当我试图这样做，它不允许我调用一个函数在同一个div / id （我试图拱文本）。

I am trying to make every letter in a small line of text a different random color. I can only seem to make it do this when I use .hover, but I want it to do the action straight away (once the page loads). Please help. I would also like to know if anyone knows how to just set different colors on each letter (set colors) with css or Javascript because when I tried to do it in that way, it wouldnt allow me call a function on the same div/id (i tried to arch the text). Thank you.

这是我的代码

var colours = ["#000000", "#FF0000", "#990066", "#FF9966", "#996666", "#00FF00", "#CC9933"], 
    idx;

$("#arch").hover(function(){
    var div = $(this); 
    var chars = div.text().split('');
    div.html('');     
    for(var i=0; i<chars.length; i++) {
        idx = Math.floor(Math.random() * colours.length);
        var span = $('<span>' + chars[i] + '</span>').css("color", colours[idx])
        div.append(span);
    }

}, function() {
    $(this).find('span').css("color","#FF0000");
});

推荐答案

    var colours = ["#000000", "#FF0000", "#990066", "#FF9966", "#996666", "#00FF00", "#CC9933"], 
    idx;

$(function() {
    var div = $('#arch'); 
    var chars = div.text().split('');
    div.html('');     
    for(var i=0; i<chars.length; i++) {
        idx = Math.floor(Math.random() * colours.length);
        var span = $('<span>' + chars[i] + '</span>').css("color", colours[idx]);
        div.append(span);
    }
});

适用于我。 jsFiddle

您必须请确保在对其进行任何jQuery作业之前加载DOM。

You have to make sure the DOM is loaded before doing any jQuery stuff on it.
