why php form input arrays act funny in jquery?

is there way overcome this?

hi, wrote code , works.. updating form of 21 radio inputs emphasize label next checked radio(s).

*visually - not in html tag 

$(function() {        for(count = 0;count<21;count++) {     result = $("input:radio[name=choice"+count+"]:checked").val();     $("input[name=\"choice"+count+"\"][ value=\""+ result +"\"]").attr("class", "magic");     $("div.radio:has(input.magic)").attr("class", "radio spell");    } $("input").click(function() {     $("div.radio:has(input.magic)").attr("class", "radio");     $("input.magic").removeattr("class", "magic");      var count = 0;     var result = 0;     for(count = 0;count<21;count++)     {         result = $("input:radio[name=choice"+count+"]:checked").val();         $("input[name=\"choice"+count+"\"][ value=\""+ result +"\"]").attr("class", "magic");         $("div.radio:has(input.magic)").attr("class", "radio spell");        } }); });

here css

input[type="radio"] { height: 20px; }  input[type="radio"] + label { color: #777; font-weight:100; letter-spacing: 1px; }  input[type="radio"].magic + label { color: black; font-style: italic; /*text-decoration:underline;*/ font-weight: 600; letter-spacing: 0px; text-align: center; display:inline-block; width: 80px; }  div.radio.spell { border: outset white 2px; }

now radio names used choice0 - choice20 , works ok.

before used choice[0] - choice[20] , did not work @ all. behaved weird.

the jquery code like: result = $("input:radio[name=choice["+count+"]]:checked").val(); ...

i wondering, there anyway around that?

thank valuable input.

[ , ] used attribute selectors in jquery, need escape them use them part of string: $(":radio[name=choice\["+count+"\]]").

that said, rather uncomfortable way of manipulating element groups. easy way create html structure reflects groups, , use find other members of group:

$(function() {     $(":radio[name^=choice]:checked").each(function() {         $(this).closest('div.radio').attr("class", "radio spell")             .find("input[name^=choice]").attr("class", "magic");     }); });

etc.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
