If and if ....else
	Looping statement
	Switch statement
	Break statement
	Continue statement

	If Statement
	If...else Statement

The first instruction that enables you to control the flow is called the "if" statement. Basically, it enables you to perform tests inside program code to determine which parts of the program should be run under any given situation.

Syntax :

If ( Condition ) {
            Statement ……
}

Example :

If ( form.marital.Value == "Married" ) {
           document.write("Mrs." );
}
If ( form.marital.Value == "Unmarried" ) {
             document.write("Miss." );
}

You can also write the preceding example in a slightly different way, by using a different version of the "if" Statement that incorporates an else statement.

Syntax :

If ( condition) {
             (Statement….. ) }
else {
             (Statement….. ) }

Example :

If ( form.marital.Value == "Married" ) {
              document.write("Mrs." );
}
else {
              document.write( "Miss.");
}

Assume that you have a web form that asks whether a person is male or female. If the property bas.n.value had been assigned a value of "male", the first document.write( ) method would have been called. If it had been assined a value of "female", the second statement would have been displayed.

Here the bas is the current form and n is the name of the field as a subobject of the form bas.

Type male or female in the first text field and Click the button "Click Me" to view the result in the second text field.
