Javascript to target specific form name?

[DSchragg]

I have a form that loads with the following hidden field:

<input type="hidden" name="packageID" value="1" />

This value can be either a 1 or 4 depending on what group you are part of on the site, however the form doesn't change.

What I want to do is customize the form a bit based on the value using something like this:

    var package = document.getElementsByName("packageID"); 
    if(package.value == '1'){
    $("#field_price_current_wrapper").hide();

    }else{

    if(package.value == '4'){
    }
}

I'm loading this in my footer after the form but it just isn't working, I'm hoping someone can tell me where I went wrong?

Thanks!

Assign an id = "packageID" to the field and then use

var package = document.getElementsById("packageID");

I'm not trying to assign a PackageID, that's already done, I want to hide fields and force values depending on whether the PackageID is a 1 or 4...

Thanks

If "PackageID" is, indeed, the ID of the element then you need to use

document.getElementById("PackageID")

to refer to it - as Philip advised you!

document.getElementsByName("SomeName")

returns an array of elements, the first of which is referred to by

document.getElementsByName("SomeName")[0]

What does your Console say? It probably confirms the above with an error message.

Guys, thank you so much for your help, and please excuse my ignorance if I wasn't getting the message you were trying to relay. I wasn't trying to add an ID to the field, nor did I want to since this is a Wordpress plugin, and I'd rather not customize it so that I can have clean updates in the future. It was adding the [0] that the did the trick....now if I could ask one more question?

How to I hide a div id/class?
Using

$("#field_price_current_wrapper").hide();

isn't working for me, what am I doing wrong?

Thanks again!

EDIT: Managed to hide the div using:

field_price_current_wrapper

Thanks again for all your help guys!
