js实现div模拟模态对话框展现URL内容

本文实例讲述了js实现div模拟模态对话框展现URL内容。分享给大家供大家参考，具体如下：

<script>function sAlert(str){ var msgw,msgh,bordercolor; msgw=800;//提示窗口的宽度 msgh=600;//提示窗口的高度 titleheight=25 //提示窗口标题高度 bordercolor="#336699";//提示窗口的边框颜色 titlecolor="#99CCFF";//提示窗口的标题颜色 var sWidth,sHeight; sWidth=document.body.offsetWidth; sHeight=screen.height; var bgObj=document.createElement("div"); bgObj.setAttribute('id','bgDiv'); bgObj.style.position="absolute"; bgObj.style.top="0"; bgObj.style.background="#777"; bgObj.style.filter="progid:DXImageTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75"; bgObj.style.opacity="0.6"; bgObj.style.left="0"; bgObj.style.width=sWidth + "px"; bgObj.style.height=sHeight + "px"; bgObj.style.zIndex = "10000"; document.body.appendChild(bgObj); var msgObj=document.createElement("div") msgObj.setAttribute("id","msgDiv"); msgObj.setAttribute("align","center"); msgObj.style.background="white"; msgObj.style.border="1px solid " + bordercolor;  msgObj.style.position = "absolute"; msgObj.style.left = "60%";   msgObj.style.top = "20%";   msgObj.style.font="12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif";   msgObj.style.marginLeft = "-525px" ;   msgObj.style.marginTop = -75+document.documentElement.scrollTop+"px";   msgObj.style.width = msgw + "px";   msgObj.style.height =msgh + "px";   msgObj.style.textAlign = "center";   msgObj.style.lineHeight ="25px";   msgObj.style.zIndex = "10001";  var title=document.createElement("h4");  title.setAttribute("id","msgTitle");  title.setAttribute("align","right");  title.style.margin="0";  title.style.padding="3px";  title.style.background=bordercolor;  title.style.filter="progid:DXImageTransform.Microsoft.Alpha(startX=20, startY=20, finishX=100, finishY=100,style=1,opacity=75,finishOpacity=100);";  title.style.opacity="0.75";  title.style.border="1px solid " + bordercolor;  title.style.height="18px";  title.style.font="12px Verdana, Geneva, Arial, Helvetica, sans-serif";  title.style.color="white";  title.style.cursor="pointer";  title.innerHTML="关闭";  title.onclick=function(){  document.body.removeChild(bgObj);   document.getElementById("msgDiv").removeChild(title);   document.body.removeChild(msgObj);   }  document.body.appendChild(msgObj);  document.getElementById("msgDiv").appendChild(title);  var txt=document.createElement("p");  txt.style.margin="1em 0"  txt.setAttribute("id","msgTxt");  txt.innerHTML=str;  document.getElementById("msgDiv").appendChild(txt);  }function ajax_form(url){ $.post(url, {Action:"POST"}, function (data) {  sAlert(data); },  "html");}</script>

用法：
代码如下:<a href='#' onclick="ajax_form('http://localhost/create_user_form.html');">test</a>
