Example 9.4:
A Shortcut to Array Creation
Click on the buttons to see what is held in the specified positions in the arrays. This page is the same as Example 9.1, except that we've used an informal method for creating the array. All but the last button will work correctly:
This is the script we used in the HEAD:
<![CDATA[
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
function makeArray(n) { }
var acode = new makeArray(187)
var area = new makeArray(187)
area[1] = "Alabama "; acode[1] = 205
area[2] = "Alabama "; acode[2] = 334
area[3] = "Alaska "; acode[3] = 907
area[4] = "Alberta "; acode[4] = 403
area[5] = "Antigua "; acode[5] = 268
area[6] = "Arizona "; acode[6] = 520
area[7] = "Arizona "; acode[7] = 602
area[8] = "Arkansas "; acode[8] = 501
area[9] = "Bahamas "; acode[9] = 242
area[10] = "Barbados "; acode[10] = 246
area[11] = "Bermuda "; acode[11] = 441
area[12] = "British Columbia "; acode[12] = 250
area[13] = "British Columbia "; acode[13] = 604
//-->
</SCRIPT>
]]>
And this form:
<![CDATA[
<FORM>
<INPUT TYPE="BUTTON" VALUE="What's in area Position 12?" onclick="alert(area[12])"><P>
<INPUT TYPE="BUTTON" VALUE="What's in acode Position 12?" onclick="alert(acode[12])"><P>
<INPUT TYPE="BUTTON" VALUE="What's in area Position 110?" onclick="alert(area[110])"><P>
<INPUT TYPE="BUTTON" VALUE="What's in area Position 500?" onclick="alert(area[500])"><P>
<INPUT TYPE="BUTTON" VALUE="What's the area length (area.length)?" onclick="alert(area.length)"><P>
</FORM>
