HELP!! Script won’t work!!

Copy linkTweet thisAlerts:
Jun 04.2009

I’ve been using Javascript for a while and I usually get things done (though, not always in the best way…:-))

I need to create a simple script to run a loop that has to output several strings.

Basically, what I need is to create a variables such as var title1 = “This is TITLE 1”; var title2 = “This is TITLE 2”; and so on. Then I need to run a loop:

for (i=i;i>=j;i=i-1) {
var whichTitle = ‘title_’ + i;

document.write(whichTitle);
}

The thing is rather than getting the text I’ve defined, I get title1 and title2 (not “This is TITLE 2”). For some reason, javascript’s not considering the original variables as the one’s needed to be passed. I’m sure I’m facing this the wrong way. HELP!!!

@astupidnameJun 04.2009 — Change this:
var whichTitle = 'title_' + i;[/QUOTE]
to the following:
[CODE]var whichTitle = window['title' + i]; //assuming you have global variables named in format: var title[number in this character position] = 'whatever'[/CODE]

This is what arrays are for.... rather than cluttering up the global namespace with a pile of variables each defining a single string, stick all the strings in an array and loop through the array instead.

@manlomasanauthorJun 04.2009 — Arrays was the way to go (or the first that worked at least!!)

Thanks guys. Hope I can pay you all back sometime.
