Example 6.18:
Breaking Out of Loops--break
The button calls function1(), which uses a 'for' loop. This displays the contents of the counter variable ( i ) in a confirm dialog box. Clicking on OK continues the loop, clicking on Cancel executes the break and ends the loop:
This is the script we used:
<![CDATA[
<SCRIPT LANGUAGE="JavaScript">
<!--
function function1() {
var bResult
for (i = 1; i < 4; i++) {
bResult = confirm("i = " + i + "\nClick cancel to execute a \'break\' statement","")
if (bResult == false) {
break;
}
}
alert("The loop has finished\ni = " + i)
}
//-->
</SCRIPT>
</HEAD>
<BODY>
<BR>
<form>
<input type="button" value=" Button A " onclick="function1()">
</form>
