Example 6.19:
Returning to the Top of The Loop—continue
The button calls function1(), which uses a 'while' loop. This displays the value held by the counter variable ( i ) in a confirm box. If you press the Cancel button, a continue statement is executed and processing goes back to the top of the loop rather than incrementing the counter variable i:
This is the script we used:
<![CDATA[
<SCRIPT LANGUAGE="JavaScript">
<!--
function function1() {
var bResult
var i = 0
while (i < 4) {
bResult = confirm("i = " + i + "\nClick cancel to execute a \'continue\' statement","")
if (bResult == false) {
continue;
}
i++
}
alert("The loop has finished\ni = " + i)
}
//-->
</SCRIPT>
</HEAD>
<BODY>
<BR>
<form>
<input type="button" value=" Button A " onclick="function1()">
</form>
]]>
