[Proto-Scripty] Re: how to change selectedIndex?
Hi Cristisor,
I think that what are u seeking is more or less this code:
1990
1998
2000
1990
1995
1998
field = 'birthdate_smarty_select';
for(var i=0;i<$(field).childNodes.length;i++){
if($(field).childNodes[i].tagName == "SELECT") {
$(field).childNodes[i].selectedIndex = 0;
}
}
So, pay attention on index of childNodes (i) not always be 1 and 2 because
this I think its good do a FOR of all elements inside of SPAN and verify if
that element is a SELECT, if is put the value 0 using selectedIndex
statement, if not dont do anything.
I test this issue on Firefox and IE 7 and works great.
Regards,
Luiz Paulo

Be wary of using direct access to the childNodes array. IE represents
all text nodes, even those that are just a newline character for your
HTML markup as an item in the childNodes array, so you're probably
referencing a text node instead of the select element you intended to.
I'd give the select element an id and reference them directly.

Why don't you use Prototype methods?
$(field).select('select').each(function(control){
control.selectedIndex = 0;
});
