JS实现字体选色板实例代码_javascript技巧



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：

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：

代码如下:

name="fontColor" type="button" value="颜色"
onclick="coloropen(event)" id="fontColor" />

var ColorHex = new Array('00', '33', '66', '99', 'CC', 'FF')
var SpColorHex = new Array('FF0000', '00FF00', '0000FF', 'FFFF00',
'00FFFF', 'FF00FF')
var current = null
function initcolor() {
getArgs();

//chat.js init();
init();

var colorTable = ''
for (i = 0; i < 2; i++) {
for (j = 0; j < 6; j++) {
colorTable = colorTable + ''
colorTable = colorTable
+ ''
if (i == 0) {
colorTable = colorTable
+ ''
} else {
colorTable = colorTable
+ ''
}
colorTable = colorTable
+ ''
for (k = 0; k < 3; k++) {
for (l = 0; l < 6; l++) {
colorTable = colorTable
+ ''
}
}
}
}
colorTable = '

'
+ '

' + '12' + '×关闭' + '

'
+ ''
+ colorTable + '';
document.getElementById("colorpane").innerHTML = colorTable;
var current_x = document.getElementById("fontColor").offsetLeft;
var current_y = document.getElementById("fontColor").offsetTop;
//alert(current_x + "-" + current_y)
document.getElementById("colorpane").style.left = current_x + "px";
document.getElementById("colorpane").style.top = current_y + "px";
}
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";
//alert("ok");
}
function coloropen() {
document.getElementById("colorpane").style.display = "";
}
window.onload = initcolor;




调试的时候，自行修改doclick方法即可。
