自己整理得一个JavaScript写的一个DIV 弹出网页对话框

网上搜索到的代码,做了一些修改该,

修正无法自定义颜色,修正IE8 下错误,以及其他小BUG 兼容IE6~8以及火狐

可以自定义

// 提示窗口标题高度 
// 提示窗口的边框颜色  
// 提示窗口的标题颜色  
// 提示窗口的标题背景色 
// 提示内容的背景色
// 提示内容文字对齐方式

功能 可以弹出一个大DIV遮住页面(IE下 透明) 然后在屏幕中央显示显示一个小DIV

可用作功能提示 操作提示 以及公告等

提示内容可以使带HTML标记的文字,也可是一个页面链接

 function MessageBox(){ this.titleheight = "21"; // 提示窗口标题高度 this.bordercolor = "#666699"; // 提示窗口的边框颜色 this.titlecolor = "#1259a4"; // 提示窗口的标题颜色 this.titlebgcolor = "#e4f1fb"; // 提示窗口的标题背景色 this.bgcolor = "#FFFFFF"; // 提示内容的背景色 this.MsgAlign="left"; this.Show=function(title, msg, framesrc, w, h) { var iWidth = document.documentElement.clientWidth; var iHeight = document.documentElement.clientHeight+document.documentElement.scrollTop*2; 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:101;"; document.body.appendChild(bgObj); var msgObj=document.createElement("div"); 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 "+this.bordercolor+";background-color:"+this.bgcolor+";padding:1px;line-height:22px;z-index:102;"; document.body.appendChild(msgObj); var table = document.createElement("table"); msgObj.appendChild(table); table.style.cssText = "margin:0px;border:0px;padding:0px;"; table.cellSpacing = 0; var tr = table.insertRow(-1); var titleBar = tr.insertCell(-1); titleBar.style.cssText = ";width:"+(w-84)+"px;height:"+this.titleheight+"px;text-align:left;padding:3px;margin:0px;font:bold 13px '宋体';color:"+this.titlecolor+";cursor:move;background-color:" + this.titlebgcolor; titleBar.style.paddingLeft = "10px"; titleBar.innerHTML = title; var moveX = 0; var moveY = 0; var moveTop = 0; var moveLeft = 0; var moveable = false; var docMouseMoveEvent = document.onmousemove; var docMouseUpEvent = document.onmouseup; titleBar.onmousedown = function(){ var evt = getEvent(); moveable = true; moveX = evt.clientX; moveY = evt.clientY; moveTop = parseInt(msgObj.style.top); moveLeft = parseInt(msgObj.style.left); document.onmousemove = function(){ if (moveable) { var evt = getEvent(); var x = moveLeft + evt.clientX - moveX; var y = moveTop + evt.clientY - moveY; if ( x > 0 &&( x + w < iWidth) && y > 0 && (y + h < iHeight) ) { msgObj.style.left = x + "px"; msgObj.style.top = y + "px"; } } }; document.onmouseup = function (){ if (moveable) { document.onmousemove = docMouseMoveEvent; document.onmouseup = docMouseUpEvent; moveable = false; moveX = 0; moveY = 0; moveTop = 0; moveLeft = 0; } }; } var closeBtn = tr.insertCell(-1); closeBtn.style.cssText = "cursor:pointer; padding:2px;background-color:" + this.titlebgcolor; closeBtn.innerHTML = "<span style="font-size:10pt;color:"+this.titlecolor+";" mce_style="font-size:10pt;color:"+this.titlecolor+";" id='closeBtn'>×关闭窗口"; closeBtn.onclick = function(){ document.body.removeChild(bgObj); document.body.removeChild(msgObj); } var msgBox = table.insertRow(-1).insertCell(-1); msgBox.style.cssText = "font:10pt '宋体';"; msgBox.colSpan = 2; if(framesrc != "") { msg = "<iframe name='frmAlertWin' id='frmAlertWin' src="about:blank" mce_src="about:blank" frameborder=0 marginwidth=0 marginheight=0 style='height:"+(h-this.titleheight-10)+"px;width:100%;'></iframe>"; } msgBox.innerHTML = "<div style="/" mce_style="/""text-align:"+this.MsgAlign+";/">"+msg+"</div>"; if(document.getElementById("frmAlertWin") != null) { document.getElementById("frmAlertWin").src = framesrc; } function getEvent(){ return window.event || arguments.callee.caller.arguments[0]; } }}

 

调用方式

var msgbox=new MessageBox();

 msgbox.Show('站内公告',"小小提示","",500,220);///参数:标题,内容(提示为连接页面时可为空),连接页面地址(使用文字是可为空),宽度,高度

 

要注意的是如果在页面加载时就要弹出提示 请将调用代码放在body标记以后 否则在IE8下回出现错误
