changing the "name" attribute of an item doesn't seem to be working when trying to change it with .attr();

in Using jQuery • 13 years ago

I don't know why but it's not working no matter how much i try to do it. I was planning on posting some elements on a page's div and one of them allows for mutiple things going on at once, as in allows for someone to have more than one of something. And since i don't think that it'll be working right if i try to pull it from 1+ items with the same name it'd just show the last one? Or is it that PHP would show them as a list... either way it's seeming that .attr() doesn't allow for a name change for some odd reason. And i was wondering if there was any function to allow for this to be changed easily written within jquery.

Hey,

An example of this problem would be nice. Cause you can change the names of elements easy with, for example:

//Change all div elements names to 'newName'
$('div').attr('name', 'newName');

Just give some example code, and the people here will help :)

var b = parseInt($('.counts').attr('id'));
var a = b+1;
$('.counts').val(a);
if (a>=2){
var ids = '.dasbonus'+a;
var ibs = '.dasbonus'+b;
var as = '.bonus stat'+a
$(ibs).attr('class',ids);
$(ibs).attr('name',as);
}
if (a==1){
$('.das bonus').attr('class','.dasbonus1');
$('.das bonus').attr('name','bonus stat1');
}

that seems to be it right there that's not allowing me to do much of anything :/ also incase you were wanting the .das bonus class it's a bunch of selects, and counts is a hidden <input> that i was using to try to track how many there were since i couldn't think of a better way to do that.

I don't thinkt the selector $('.das bonus') will work. How does the element look? Like <input class="das bonus" /> ? If so the correct selector should be $('.das.bonus').

Let me know if that is the case.

<select name="bonus stat" class="das bonus"><option value="">Stat</option><option value="1">Agility</option></select>

Well than the selectors should be:

$('.das.bonus').attr('class','.dasbonus1');
$('.das.bonus').attr('name','bonus stat1');

Only thing I can think of that would be the problem.

holy...shit i feel like a complete moron... i forgot a freaking space... from now on... i'm sticking with _ for spaces(since my spacebar is being finicky as of late). I don't know why i thought i could just put an actual " " instead of the _ knowing how things work now a days... oh well glad that i had someone else show me my moronic mistake... i can't believe i didn't see it... spent ~30min trying to figure why that one thing wasn't working for me. Since the rest of the page has dynamic DOM, changing of elements, values, etc. etc.

Yeah that could the error right there. Just a little heads up: jQuery standard uses the camelback notation. So it should be dasBonus instead of das_bonus :)

yeah i guess but naming stuff like that's never really sat well with me as far as remembering it later down the line.

ok that's not it apparently.... now the second part's not writing the variables for some reason and i cannot figure out why.

Also it seems that name still doesn't work but the class part was changing for the first one the rest are not and i've even changed it so that that part of the code is now this.

var b = $('.counts').attr('value');
var c = parseInt(b);
var a = c+1;
$('.counts').attr('value',a);
if (a>2){
a=a+'';
c=c+'';
var ids = '.das_bonus'+a;
var ibs = '.das_bonus'+c;
var as = '.bonus stat'+a;
alert(ibs);
alert(ids);
alert(as);
$(ibs).attr('name',as);
$(ibs).attr('class',ids);
}
alert(a);
if (a==1){
$('.das_bonus').attr('class','.das_bonus1');
$('.das_bonus1').attr('name','bonus_stat1');
}

the alerts are telling me that it's all working properly/as it should.... so i don't know why it's not just taking it and doing what it's supposed to as it was in the lower part. It seems that it's just i don't know... i have no logical reasoning for why it's not working.

Think about these two lines of code:
      $('.das_bonus').attr('class','.das_bonus1');
      $('.das_bonus1').attr('name','bonus_stat1');

The first line selects an element with the class das_bonus and gives it the class.das_bonus1. literally, .das_bonus1. asin, <div class=".das_bonus1"></div>

Therefore, for the second line to work, the class selector would be .\\.das_bonus because "." is a reserved character in jquery and has to be escaped if used as a literal charater in a class name. Try changing those two lines of code to:
      $('.das_bonus').attr('class','das_bonus1'); // removed "."
      $('.das_bonus1').attr('name','bonus_stat1');

Edit: you could also chain those attr or combine them:

1: $('.das_bonus').attr('class','das_bonus1').attr('name','bonus_stat1');
2: $('.das_bonus').attr({'class':'das_bonus1','name':'bonus_stat1'});

i see what my old problem was i had to basically add a new one with it's name being "das_bonus0" and "bonus_stat0" so that it'd actually read/write properly silly me.

ok now there's a new problem .val still doesn't work so that's still up in the air.
