Incrementing variable names in loop??

[WolfShade]

Can it be done?

What I have is a form that is currently static; it will eventually be dynamically generated with tabs that can be anywhere from 1 to 100 tabs, using <DIV id="contentblockx"> surrounding tables that will provide different fields depending upon what tab is clicked. Since the number of tabs will be dynamic, I need to create dynamic form validation.

In normal validation, I create a variable called warn and set it to equal "", then if anything erroneous happens, warn += "blah blah blah"; if warn !="" then alert(warn) else return true.

I'd like to have as many warn variables as there are tabs (warn1 through warn[x]). Unfortunately, I can't figure out how to establish a warn[x] in the for loop.

for (a=1; a<numberOfTabs+1; a++) {
warn[a]="";

-= validation stuff goes here =-
}

.. isn't working. Even putting it within an eval() didn't do it. Any suggestions? I've been searching a lot and have not yet found anyone else asking this question (yet), nor any kind of tutorial on how to do it. Any suggestions?

Thank you for your time.

if I understood you correctly????

in the loop do something along these lines
if(there is an error){
warn[x]="blah blah&lt;br&gt;";
}

and once all is done you check to see if there is data in warn
if(warn.length>0){
//run a loop to print errors
}

I love it when I figure something out that's been kicking my butt for hours. I also hate it when I figure it out AFTER I've posted a question to a forum.

Khalid, thanks for your suggestion. I think it may be similar to what I've done. I've tested it, and it works great. Now, I read your sticky about placing script under the PHP headers; I've never done it before, but I'll test it, here. The following is what finally succeeded:


function checkData() {
warn = "";
df = document.customize;
warnb = new Array(numberOfTabs+1);
warnc = 0;

for (a=1; a<numberOfTabs+1; a++) {

warnb[a] = "";
if (eval("df.TabType"+a+".options[df.TabType"+a+".selectedIndex].value") == 0) {
warnb[a] = "Description of ERROR\n";
}

if (warnb[a] != "") {
warnb[a] = " ----- Tab " + a + " Validation Issue -----\n" + warnb[a];
warnc = 1;
}
warn = warn + warnb[a];
}
if (warnc == 0) {
return true;
}
else {
alert('* * * PLEASE MAKE THE FOLLOWING CORRECTIONS * * *\n_______________________________________________\n\n' + warn);
return false;
}
}


Now, granted, the selectedIndex could just as easily have just been left to selectedIndex as opposed to options.value, but I included that just in case the select value is not the same as the selectedIndex (like an actual word.)

Thanks!
