Dynamically Created Array

Question

I have some <inputs> that are dynamically created, and when checked they create a dynamic array, which gets stuffed into an .ajax post. All of it works with the exception of the dynamically created array. If I manually create the array it works fine, I'm just having trouble creating it dynamically. The numbers used in the ID (infoID1, infoID2, infoID3) and Values (1,2,3) are created via a PHP loop (infoID{$x}).

Sample inputs

<input id="infoID1" type="checkbox" value=1/>
<input id="info1" type="text" value="something good"/>

<input id="infoID2" type="checkbox" value=2/>
<input id="info2" type="text" value="something bad" />

<input id="infoID3" type="checkbox" value=3/>
<input id="info3" type="text" value="something ugly" />

The below dataArray is where I'm having all kinds of problems. I need to put both the ID and Value of the checked boxes in this dynamically created dataArray (using some type of loop) and add sequential numeric values to both the ID variable (infoID + 1 becomes infoID1) and the values (1,2,3)

so it will end up looking like this...

var dataArray = {
    infoID1 : 1,
    info1 : "something good",
    infoID2 : 2,
    info2 : "something bad",
    infoID3 : 3,
    info3 : "something ugly"
};

The dataArray then gets stuffed into the .ajax post below. The .ajax section is working fine.

$.ajax({
    url: "workingPage.php",
    data: dataArray,
    type: 'POST',
    success: function (otherData) {
        $(doStuff);
    }
});

Any help is appreciated!

Here is some changes to do :

1- Add name to your inputs like this :

<form name="myForm" id="myForm">
<input id="infoID1" name="mycheckboxid[]" type="checkbox" value=1/>
<input id="info1" name="mycheckboxvalue[]" type="text" value="something good"/>

<input id="infoID2" name="mycheckboxid[]" type="checkbox" value=2/>
<input id="info2" name="mycheckboxvalue[]" type="text" value="something bad" />

<input id="infoID3" name="mycheckboxid[]" type="checkbox" value=3/>
<input id="info3" name="mycheckboxvalue[]" type="text" value="something ugly" />
</form>

2- Use serialize() function :

$.ajax({
    url: "workingPage.php",
    data: $('form#myForm').serialize(),
    type: 'POST',
    success: function (otherData) {
        $(doStuff);
    }
});

That's it.

I tried a methond of .serialize before and I couldn't get it to work, but I also don't have the inputs in a form. I tried so many different methods that I have them all confused now. I'll give it a shot and let you know. Thank you!

If you can't change your code for some reasons, you can use $.each loop on your inputs and create your array. even knowing this not the best way, the way you do it, but here is the code : $(document).ready(function(){ var inputs = $('input'), dataArray = {}; $.each(inputs, function(index, input){ dataArray[$(input).attr('id')] = $(input).val(); }); // your ajax query here });

I remember why .serialize didn't work for me. I have other data that I can't get from .serialize (div's and spans), but stuffing the data into the array and posting it via .ajax did work. However, your 2nd suggestion of using .each will work very well for what I need. Thanks for both suggestions.
