getting the value of a checkbox like var[id]

[firepages]

Hi, any ideas how I can check via javascript if these checkboxes have been checked or not?

<input name="Oct31[adult]" type="checkbox" value="1" onclick="addit();">
<input name="Nov1[adult]" type="checkbox" value="1" onclick="addit();">
<input name="Nov2[adult]" type="checkbox" value="1" onclick="addit();">
<input name="Nov3[adult]" type="checkbox" value="1" onclick="addit();">

I know if I use "Oct31_adult" etc but I would rather not if there is a straightforward way in javascript ???

<input name="Oct31[adult]" type="checkbox" value="1" onclick="addit(this);">

function addit(objChk){
alert(objChk.checked)
}

Hi glenngv , I can see where you are going... but I am not sure if I can use that in the way I need to ?

err its easier to show than explain :)

http://www.firepages.org/calculate.html

at the moment the form adds up number of tickets * price - but I need it to do that for each day as well ?


(I know the codes a mess but its PHP output)

[glenngv]

do you mean in the addit() function, you always want to check only for Oct31[adult] checkbox? not the one whose checkbox is clicked?

Hi sorry I have problems saying what I mean :)

the addit() function is just meant to recalculate the form totals whenever any of the form inputs is altered (and shoulf by default have at leat one day selected - just not done that yet)

so say someone wants 3 adult tickets @ $13 each then at the moment the form works out that $39 is the total - but thats only for one day

ideally if the user then selected 2 more dates then that would knock the total up to $117 etc

so addit does no more than recalculate all the form values , so the calculation would then be...

(Oct31[adult]+Nov1[adult]+Nov2[adult]+Nov3[adult])*(10 * document.bella1.adult.value);

but 'Oct31[adult]' appears to be meaningless to javascript ... I could do this...

document.bella1.Oct31_adult.value + etc using name="Oct31_adult" etc

but I would rather have the Oct31[adult] array format if possible ?

document.bella1.elements['Oct31[adult]'].checked

Maybe this will be helpful...

If you name all the checkboxes from one row (ie "adult" ticket row or "child", etc.) the same, then you could treat them like an array - just like radio buttons. That would make it easer to add things up and also make the javascript easier to understand I think.
