Hello Component Files

The files for the Hello component establish how to generate the personalized greeting. The template for the Hello page contains the following HTML elements:

<HTML>
<HEAD>
  <TITLE>Hello World!</TITLE>
</HEAD>
<BODY>
  Hello <WEBOBJECT NAME = "NAME_STRING"></WEBOBJECT>!
</BODY>
</HTML>

The declarations file contains the following declaration of a WOString object to substitute the user's name for the NAME_STRING WEBOBJECT element:

NAME_STRING: WOString {value = nameString};

WOString objects, like WOTextField objects, have a value attribute. The WOString is responsible for getting the value in nameString and putting it in the corresponding page.

The script for the second page contains only one line:

id nameString;

The nameString variable must be declared so it can be associated with the NAME_STRING element in the template file. Recall that nameString is set from the Main component in the sayHello method.
