12 Section 17.2 Adding Interactivity Using Scripting Client-Side Scripts client-side scripts Some scripting languages, known as client-side scripts, are designed to be transferred to the users computer along with the HTML code. client-side script A script that is executed by the users Web browser. (p. 483) pp

(p. 484) pp More JavaScript elements: Functions Variables Conditional statements
