Module 8: Events and Input Fields

CMPS 162: Introduction to Programming


JavaScript can be embedded into webpages in multiple ways and depending on the context one may be better than another. It is also possible to include comments about the source code to help the reader understand the code. Interaction of the user with the browser is driven by events and we will look at several different kinds. An event is an action that results in a function call, for example, when someone clicks their mouse on the page a function is called that can then update the page depending on where the mouse was clicked. Events often get and set the content of text fields.
