本文實(shí)例講述了js實(shí)現(xiàn)div模擬模態(tài)對(duì)話框展現(xiàn)URL內(nèi)容。分享給大家供大家參考，具體如下：

<script>

function sAlert(str){

 var msgw,msgh,bordercolor;

 msgw=800;//提示窗口的寬度

 msgh=600;//提示窗口的高度

 titleheight=25 //提示窗口標(biāo)題高度

 bordercolor="#336699";//提示窗口的邊框顏色

 titlecolor="#99CCFF";//提示窗口的標(biāo)題顏色

 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="關(guān)閉";

  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：

代碼如下:

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

希望本文所述對(duì)大家JavaScript程序設(shè)計(jì)有所幫助。
