Javascript 颜色选择器更新输入值
好吧，我花了一整天的时间在这上面，我错过了一些东西，就是想不出来。我正在使用这个简单的颜色选择器 我试图做的是更新背景颜色，然后是字体颜色，让用户看到实时结果，并在文本输入框中自动更新十六进制颜色代码。下面是我的代码Javascript 颜色选择器更新输入值,javascript,jquery,html,forms,color-picker,Javascript,Jquery,Html,Forms,Color Picker,好吧，我花了一整天的时间在这上面，我错过了一些东西，就是想不出来。我正在使用这个简单的颜色选择器 我试图做的是更新背景颜色，然后是字体颜色，让用户看到实时结果，并在文本输入框中自动更新十六进制颜色代码。下面是我的代码 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transit

问题是它不会实时更新输入

var field2update = $('#divUpdateID')[0].innerHTML;
if (field2update=='colorcode') {

什么不起作用？你的问题是什么？我需要它来更新颜色十六进制值，这很有帮助，我有一个工作，但我如何为每个不同的选择器？下面是@smitty再次更新的实时示例，展示了如何更新
