Hi kevin.

Here is a solution:

Add one button in your ASPX page

ex:

        <asp:Button ID="Button1" OnClientClick="return getProperties()" runat="server" Text="Get Object Properties" Width="278px" />

then, in your <head> ... </head> add this JavaScript function

    <script type="text/javascript" language="javascript">        
    function getProperties() {
        var myObject = new Object(); //Create new object
        var objPropertiesString = "";
        myObject["firstName"] = "Hajan";
        myObject["lastName"] = "Selmani";
        
        for(p in myObject)
        {
            objPropertiesString += p + " - Value :" + myObject[p] + "\n";        }
        alert(objPropertiesString); //Show all properties and its value
        }
    </script>

Analyze the code. If you have anything to ask, write back :).

There are two ways to write error-free programs; only the third one works.

Nice Hajan,

Me too was going for similar approach:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">

        var obj = new Object();
        obj.a = 'a1';
        obj.b = 'b1';
        obj.c = 'c1';
        for (f in obj) {
            document.write('o.' + f + ' = ' + obj[f]);
            document.write('<br/>');
        }
       
    </script>
</head>
<body>
</body>
</html>

javascript
