New Variable problem

Copy linkTweet thisAlerts:
Oct 28.2006

lol I asked the wrong question in my last post…lol
Here is what I’m really looking for:

[CODE] function checkbox(i) {
var time = new Date();
var hours = time.getHours();
var minutes = time.getMinutes();

if (document.form.check_i.checked == true) {
document.form.text_i.value = hours + “:” + minutes;
} else if (document.form.check_i.checked == false) {
document.form.text_i.value = “”;
}
}[/CODE]

You can see text_i and check_i. I need the ‘i’s to be replaced with the value of ‘i’. Is there a way to do that?

@BuilderQOct 28.2006 — You could try using the elements array, which allows you to refer to each input in a form based on how many preceded it. For example, if i starts at 1, there are no other elements in the form aside from the textboxes and checkboxes, and the form itself is named "form", this function would work:
[code=php]
function checkbox(i) {
var time = new Date();
var hours = time.getHours();
var minutes = time.getMinutes();

if (document.form.elements[i*2-1].checked == true) {
document.form.elements[i*2-2].value = hours + ":" + minutes;
} else if (document.form.elements[i*2-1].checked == false) {
document.form.elements[i*2-2].value = "";
}
}
[/code]

@maiku_no_jutsuauthorOct 28.2006 — okies, i was using getElementbyID at one point, thinking it did what element did....but then i found out it wasnt and was back to square one...i was close, but not close enough, thanks

@NaldzOct 29.2006 — instead of using the dot notation:
[CODE]
document.form.text_i.value;
[/CODE]
you can also refer to elements this way:
[CODE]
document.form['text_'+i].value;
[/CODE]

@KorOct 30.2006 — or even better:
<i>
</i>document.forms['form'].elements['text_'+i].value

Success!
