这篇文章主要介绍了javascript弹出层输入框(示例代码)。需要的朋友可以过来参考下，希望对大家有所帮助
如下所示：
代码如下:
<script language="javascript" type="text/javascript">
function alertWin(title, msg, w, h) {
var titleheight = "22px"; // 窗口标题高度
var bordercolor = "#666699"; //窗口的边框颜色
var titlecolor = "#FFFFFF"; // 窗口的标题颜色
var titlebgcolor = "#666699"; // 窗口的标题背景色
var bgcolor = "#FFFFFF"; // 内容背景色
var iWidth = document.documentElement.clientWidth; //这个窗口的宽度
var iHeight = document.documentElement.clientHeight; //这个窗口的高度
//背景层的格式
var bgObj = document.createElement("div");
bgObj.style.cssText = "position:absolute;left:0px;top:0px;width:" + iWidth + "px;height:" + Math.max(document.body.clientHeight, iHeight) + "px;filter:Alpha(Opacity=30);opacity:0.3;background-color:#000000;z-index:1000;";
document.body.appendChild(bgObj);
var iframe2 = document.createElement("iframe");
iframe2.style.cssText = "position:absolute; top:0px;filter:Alpha(Opacity=30);opacity:0.3;background-color:#000000; z-index:1001; border-style:none; border-width:0px; border:0px;width:" + iWidth + "px;height:" + iHeight + "px";

//创建一个弹出层
var msgObj = document.createElement("div");
//设置弹出的层的样式
msgObj.style.cssText = "position:absolute;font:11px '宋体';top:" + (iHeight - h) / 2 + "px;left:" + (iWidth - w) / 2 + "px;width:" + w + "px;height:" + h + "px;text-align:center;border:1px solid " + bordercolor + ";background-color:" + bgcolor + ";padding:1px;line-height:22px;z-index:1001;";
document.body.appendChild(msgObj);
//创建一个table用于容纳层上的内容
var table = document.createElement("table");
//将Table放到弹出层上
msgObj.appendChild(table);
//设置table的格式
table.style.cssText = "margin:0px;border:0px;padding:0px;";

//插入一行用于显示标题
var tr = table.insertRow(-1);
//插入一个单元格用于容纳标题
