I need to extract data from an HTML form with javascript(+Mootools) in the same kind of nested object format that PHP would see it when the form is posted.
Am I just bad at googling or is there really no native nor a well-known way to achieve this? I see many others have asked the same question in different forums but so far all have accepted solutions like jQuery serializeArray and such.
I tried out serializeArray with jsFiddle http://jsfiddle.net/7quxe/ and the results were disappointing.
I've previously written a script for this myself and it worked quite well except it had some problems when the form had overlapping mixed key type fields (<input name=foo[bar] value=1> and <input name=foo[] value=2. I've already started working on a better version but as I found myself starting over again and again, I thought to myself: There are lots of great js libraries out there that aim to solve many basic everyday problems. Can it really be that wanting to extract data from a form in a properly formatted object is not that common?
Here is an example of what I'm attempting:
<form method=post action=/>
<input name=test value=test>
<input name=nested[a] value=a>
<input name=nested[b] value=b>
<input name=nested[c] value=c>
<input name=arraytest[] value=foo>
<input name=arraytest[] value=foo>
<input name=arraytest[] value=foo>
</form>
Here's how PHP would see this:
$_POST = array(
'test' => 'test',
'nested' => array(
'a' => 'a',
'b' => 'b',
'c' => 'c',
),
'arraytest' => array(
0 => 'foo1',
1 => 'foo2',
2 => 'foo3'
)
)
and this is what I'd like to get in js:
{
test : 'test',
nested : {
a : 'a',
b : 'b',
c : 'c'
},
arraytest : { // This could also be an array ['foo1','foo2','foo3']
0 : 'foo1',
1 : 'foo2',
2 : 'foo3'
}
}
