Use javascript to open the modal dialog box of the sample code

**1. The standard approach **

<script type="text/javascript">  
function openWin(src, width, height, showScroll){  
window.showModalDialog (src,"","location:No;status:No;help:No;dialogWidth:"+width+";dialogHeight:"+height+";scroll:"+showScroll+";");  
}  
</script>

Example: < Span style = “CURSOR: pointer” onclick = “openWin (’ / / www.jb51.net ’, ‘500 px’, ‘400 px’, ‘no’) ”> Click < / span>

Window. Open (‘openwin.html’,‘newWin’, ‘modal=yes, width=200,height=200,resizable=no, scrollbars=no’);

**3. How to automatically determine the browser **

<input type="button" value=" Open the dialog box " onclick="showDialog('#')"/> 
  <SCRIPT   LANGUAGE="JavaScript"> 
  <!-- 
  function   showDialog(url) 
  { 
   if(   document.all   ) //IE 
   { 
   feature="dialogWidth:300px;dialogHeight:200px;status:no;help:no"; 
   window.showModalDialog(url,null,feature); 
   } 
   else 
   { 
     //ModelessDialog can replace modal with dialog=yes ;
   feature ="width=300,height=200,menubar=no,toolbar=no,location=no,"; 
   feature+="scrollbars=no,status=no,modal=yes";   
   window.open(url,null,feature); 
   } 
  } 
  //--> 
</SCRIPT>

4. In IE, modal dialogs hide the address bar, but not necessarily in other browsers

Note: in a Google browser, this mode is also disabled.

**How does this work? **

        /// displays the details of an order through a modal dialog, and the screen changes color
        function ShowOrderDetails(orderId) {
            var url = "details.aspx?orderID=" + orderId;
//            $("body").css("filter", "Alpha(Opacity=20)");
            //filter:Alpha(Opacity=50)
            $("body").addClass("body1");
            ShowDetailsDialog(url, "600px", "400px", "yes");
            $("body").removeClass("body1");
        }

In addition, there is a style sheet definition The body1 { Background - color: # 999999; The filter: Alpha (Opacity = 40); }
