Java - forms[0].buttons

alexx · 21 Jun 2012 at 12:34

I'm having a quirk on one clients computer in all browsers - that when they submit information and click "save changes" sometimes it will save the data and other times it wont. I've never seen this problem or issue with any other client but was wondering if it's worth looking into java compatibility further?

I was using forms[0].buttons to determine existence of something. This uses the shortcut accessor method, whereas longhand you use forms[0].elements['buttons']

shortcut accessor is not defined as W3C method. What I'm wondering is if anyone else on the web has noticed a depracation of this method, as no other clients have complained about this code not working

First of all, Java != Javascript. They are very, very different.

Secondly, can you post your code as it seems a very odd way of doing things.

Sorry for lazy title.

I don't really have any to hand but its easy to make:

create form with <input name="buttons"> and check for existence of form with if (document.forms[0].buttons) alert('yes')

Ahh, I understand now, I thought you were trying to use .buttons as a collection of all the buttons in the form.

I've created a fiddle to test and it seems to work in FF, IE9, Chrome etc.

You could try using document.getElementById instead as that will definitely work in all browsers.

yup like I say it's always worked just this 1 case out of about 1000 accounts.. can't pinpoint it to anything else other than the possibility of this and the clients setup with a local error

If you're really bothered about typing out 'JavaScript' then just call it JS as referring to it as Jave makes it look like you don't know what you're talking about!
