JavaScript Primer

This is a very basic JavaScript primer. It should get you going in a matter of minutes. There's a lot more you can do with JavaScript...this is only meant to get true beginners started.

To start a script inside an HTML document
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
<SCRIPT LANGUAGE="JavaScript">
<!-- This hides the script
.
.
.
// This stops hiding -->
</SCRIPT>


If the script is in another document
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
<SCRIPT LANGUAGE="JavaScript" SRC="path_to_file">

After the </SCRIPT> you can add a message for those without JS capability
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
<NOSCRIPT>
Sorry, you don't have JavaScript
</NOSCRIPT>

Basic Commands
-=-=-=-=-=-=-=
document.write("Writes to HTML document - Can be HTML")
document.writeln("Same as above, but adds a return")

var varName="string"
var varName = 324
var varName             //Defines a variable

function funName() {    //Defines a function
  //Code
}

alert("Message")    //Displays an alert...user can just click OK
confirm("Message")  //Displays a Yes/No prompt and returns a boolean
prompt("Msg","Def") //Prompts for text with an inital value of Def

NOTE: You can set varnames to function calls and the value returned will be 
      stored.
