I need to draw like image 1 in file attach.

But after i write code:

Code:

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<script type="text/javascript">
function Ve()
{
    var n = document.getElementById("txtGiatri").value;
    var i,j; 
    
   for(i=1;i<=n;i++)
   {
       for(j=0;j<n-i;j++)
      document.getElementById ("place").innerHTML +="&nbsp;";
       for(j=i;j>0;j--)
            {
              document.getElementById ("place").innerHTML +=j;
            
         }
      document.getElementById ("place").innerHTML +="<br/>";
   }

}
</script>
<body>
<table>
    <tr>
        <td><input name="txtGiatri" type="text" id="txtGiatri" /></td>
        <td><input name="btnVe" type="button" value="Ve" onclick="Ve();" /></td>
    </tr>
    <tr>
        <td><div id="place"></div></td>
        <td></td>
    </tr>
</table>
</body>
</html>

i only have like image 2.

All you need is some spacing. Try adding some more  s in between your numbers (after the number is echoed).

EDIT: Oops, didn't look quite that closely. I see, it's more than that. I'll try to think of something. Sorry!

I wouldn't - make him solve it himself!

To the OP: lesson 1: don't just write (copy?) some code and hope it might magically provide the solution. Try phrasing the aim in plain English. Actually writing that down should clarify and lead you to a solution.
