variables problem

**becknetstat** · 01-04-2005 05:53 AM

i would like to do this, but no works:

function putOn()
{
for (i = 0; i <document.f.elements.length; i++)
{
document.f.c"i".checked = true; ( checkbox)
document.f.st"i".value ='5'; (combo box)
}
}

I have multiple checkboxes, and combo boxes with this names:
document.f.c1, document.f.st1
document.f.c2, document.f.st2
"""

and I woul like to reference all documents
I tried to do this:

document.f.c+i+.checked = true;
document.f.st+i+.value ='5';

but no works

Objects in JavaScript can also be addressed as associative arrays:

document.f.c['i'].checked = true

thanks Charles

I tried to to this, but no works

function putOn()
{
for (i = 0; i <document.f.elements.length; i++)
{
document.f.c['i'].checked = true;
document.f.st['i'].value = '5';
}
}

for example, in Php I can do:

PHP Code:


for ($i=1; $i<$max; $i++)

{

document.f.st".$i.".value= '5';

document.f.c".$i.".checked = 1;

}

and create a loop for for do this:

document.f.st1.value='5'
document.f.c1.checked= 1

document.f.st2.value='5'
document.f.c2.checked= 1

document.f.st3.value='5'
document.f.c3.checked= 1

document.f.st4.value='5'
document.f.c4.checked= 1

but I don´t know hom do something similar in javascript

Try:

function putOn()
{
for (i = 0; i <document.f.elements.length; i++)
{
document.f.c[i].checked = true;
document.f.st[i].value = '5';
}
}

<HTML>
<Head>
<Script Language=JavaScript>

function putOn(isForm){

nElements = isForm.length;
for (i=0; i<nElements; i++)
{
if (isForm[i].type == 'checkbox'){isForm[i].checked = true}
if (isForm[i].type == 'text'){isForm[i].value = '5'}
}
}

</Script>
</Head>
<Body>
<Form name='f'>
C1: <input type=checkbox name='c1'>
C2: <input type=checkbox name='c2'>
C3: <input type=checkbox name='c3'>
<br>
ST1: <input type=text name='st1' size=5>

thanks for your answers

I tried to do

i = 1;
document.f.c[i].checked = true;

no works

error: object 'document.f.c' is null or not an object

but if I do this:
document.f.c1.checked = true;

WORKSSS

!!!!!, checkbox "c1" its selected, but I can´t do a bucle for select all the checkboxes "c[i]" example.(c1, c2, c3, c4, c5,....)

WHY????

Just use something like this in your loop:

document.f['c'+i].checked=true;
