.Each() with input array

Question

I'm having trouble getting .each() function to work with an array of textboxes. I can't seem to figure out what I'm missing.

If I used $("input[type=text]").each() it works fine.

If I used $("[name=age[]]").each() it doesn't work.

<?php 
  //this code is abbreviated
  foreach ($dbresult as $obj) {$output = "<input type='text' name='age[]' value='" . $obj['age'] . "'";}
?>
$(document).ready(function () {
    $("#form").submit(function () {
        $("[name=age[]]").each(function () {
            if (!$.isNumeric($(this).val())){return false;}
        return true;});
});

Post your rendered HTML, not the PHP.

You need to esacpe [], thus change your selctors as

 $("[name=age\\[\\]]")

DOCS

To use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[]^`{|}~ ) as a literal part of a name, it must be escaped with with two backslashes: \.

Or you can use Attribute Starts With Selector [name^="value"], like

$("[name^=age]")

if you are using array you have to try following code

$.each( yourarrayname, function( key, value ) {
  alert( key + ": " + value );
});

$("[name=age[]]") doesn't seem to be a valid selector. Try $("[name^=age]") instead.

This doesn't work if you have also other fields with names starting with the letters "age", for example "agelimit"
