Creating while Loop StatementsThere are other loops besides the for loop in JavaScript, such as the while loop. The while loop tests a condition each time the loop is executed. If the condition is true, it executes the code in the loop. Here's what this loop looks like in outline: while ( condition ){ code } For example, here's how you write the example we used in the discussion of for loops as a while loop: Listing ch06_09.html<HTML> <HEAD> <TITLE> Using the while Statement </TITLE> </HEAD> <BODY> <CENTER> <H1> Using the while Statement </H1> </CENTER> <SCRIPT LANGUAGE = "JavaScript"> var loopIndex = 0 while(loopIndex < 10){ loopIndex++ document.writeln("The loop index value is " + loopIndex + "<BR>") } </SCRIPT> </BODY> </HTML> You can see the results of this code in Figure 6-9.
