Heris the javascript code.It works ffine but i would like to know what is the meaning of line this.SetData=SetData and next three lines after this(in bold) because when i remove them and try calling the functions via object I am not able to do so. Is it always necessary to do this when using function of these kind.
print("<html>
<head>
<Script language="JavaScript">
function MyClass()
{
var m_data = 15;
var m_text = "indian";
**this.SetData = SetData;
this.SetText = SetText;
this.ShowData = DisplayData;
this.ShowText = DisplayText;**
function DisplayData()
{
alert( m_data );
}
function DisplayText()
{
alert( m_text );
return;
}
function SetData( myVal )
{
m_data = myVal;
}
function SetText( myText )
{
m_text = myText;
}
}
var Obj1 = new MyClass();
var Obj2 = new MyClass();
Obj1.SetData( 30 );
Obj1.SetText( "Obj1: my cuntry" );
Obj2.SetData( 60 );
Obj2.SetText( "Obj2: my first javaScript progarm" );
Obj1.ShowData();
Obj1.ShowText();
Obj2.ShowData();
Obj2.ShowText();
</script>
</head>
</body>
</html>");
