Problems with "if" statement

Copy linkTweet thisAlerts:
May 29.2004

<script>

function lala() {

for (i=0;i<5;i++) {

if (document.forma.elements[“pole[“+i+”]”].value == “1”){

document.forma.elements[“pole[“+i+”]”].value = “Slava”

}

}

}

</script>

<form name=forma>

<input type=text name=pole[1] value=”1″>

<input type=button onclick=”lala()”>

</form>

=========================

Internet Explorer shows error “document.forma.elements[…].value is not an object” and doesn’t do anything

if I replace “<input type=text name=pole[[b]1[/b]] value=”1″>” on “<input type=text name=pole[[b]0][/b]] value=”1″>”, script will work, but still displays error.

Why is it? How to fix&

@SmittyMay 30.2004 — Congratulations, your IF statment does work!

Its your html code thats causing the error.

(i=0;i<5;i++)

goes from 0 -> 4

but you start at pole[1], so its crashing when its trying to find pole[0].

When u change the name to pole[0], the loop then try's to find pole[1],pole[2] ,pole[3] ,pole[4]

Have a crack at tihs below. I haven't changed the If statment, just the html its accessing.

**********************************************************************
<script>

function lala()

{

for (i=0;i<5;i++)

if (document.forma.elements["pole["+i+"]"].value == "1")

document.forma.elements["pole["+i+"]"].value = "Slava"

}

</script>

<form name=forma>

<input type=text name=pole[0] value="0"><br>

<input type=text name=pole[1] value="1"><br>

<input type=text name=pole[2] value="2"><br>

<input type=text name=pole[3] value="3"><br>

<input type=text name=pole[4] value="4"><br>

<input type=button onclick="lala()" value="lala()">

</form>

Success!
