純JSweb調(diào)色板控件（瀏覽器兼容小巧好用）

1、.;本人第一次做純JS控件，今天拿出來供大伙拍磚，歡迎各位修改完善，如果那位大俠完善后希望能夠給小弟發(fā)一個(gè)版本，以供學(xué)習(xí)（）謝謝。此JS控件是以JQUERY1.4.2為基礎(chǔ)框架實(shí)現(xiàn)WEB調(diào)色板功能，解決了瀏覽器兼容性問題。在同一頁面上可以供多個(gè)控件調(diào)用。效果圖：調(diào)用方法：調(diào)用jquery-1.4.2.min.js 1.4.2版JQUERY調(diào)用頁添加HTML 添加如下JS：$(document).ready(function() ShowColorControl(txtBackgroundColor););txtBackgroundColor 為添加調(diào)色板功能的控件ID實(shí)現(xiàn)方法：/綁定控件 調(diào)用
