摘要：JS实现字体选色板实例代码

哎，前段开发真心不容易。。。。弄了1个小时，找找了各种素材，终于，字体选色板基本功能弄好了，UI设计技能亟待提升。先看效果： [img]http://files.jb51.net/file_images/article/201311/20131120153209652.jpg[/img] 功能介绍：点击颜色按钮，弹出选色板，选中一个颜色，保存设置，隐藏选色板。。。实现源码如下：

[u]复制代码[/u] 代码如下:

    '00FFFF', 'FF00FF')

  function initcolor() {
   getArgs();

   //chat.js init();

   document.getElementById("colorpane").innerHTML = colorTable;

  function doclick(obj) {
   //document.getElementById("fontColor").value = obj;
   document.getElementById("colorpane").style.display = "none";
   document.getElementById('msgbox').style.color = obj;
   //alert(obj);
   //var chatArea = frames["chat"].document
    // .getElementsByName('chatArea');
   //for ( var i = 0; i < chatArea.length; i++) {
   // chatArea[i].style.color = obj;
   //}
  }
  function colorclose() {
   document.getElementById("colorpane").style.display = "none";

  }
  function coloropen() {
   document.getElementById("colorpane").style.display = "";

</body>
</html>

调试的时候，自行修改doclick方法即可。
