It makes since that, when working with javascript, document.getElementById() can't find the Id of an object that hasn't yet been added to the DOM, however when I nest document.getElementById() in a function and call it after the object has been created, document.getElementById() still can't find the object. is there a way around this? if not, can someone at least explain to me why it doesn't work? Thank You

I'm trying to use the Fb PHP SDK to execute different Js document.getElementById innerHTML functions, depending on whether the user is logged in to Fb or not. For some reason the function won't work for me. I know my API connection is successful, and Javascript can be inserted here, as I can call alternative alert functions ("you are logged in" :you are not logged in") in this way. But the getElementById function won't work. I've tried moving the script to the body etc, nothing working. Any ideas? It's probably a rookie question, but I'd love it if there was a …

I have a problem with google maps. I want to 'click' a marker remotely (that is to say the user will be able to click on a button and affect the marker, as though the marker itself had been clicked). Not a problem except I don't know how to name the marker, or alternatively, find out what it has been named in the google load() process. Once I know its name I can do the rest. Can anybody help ?

Hi forum, This will probably be an easy one but i have a situation where i have multiple PHP/HTML <SELECT> tags. So i hold their id and name in an array. When i go to call this enableBox JavaScript function and i try to call the selectorName[] using the getElementById command, i get a null reference. How can i make this work, using the getElementById command in JavaScript to access the selectorName[] in PHP/HTML so that i can enable and disable a box depending on whether other has been selected in the dropdown selector? PHP [CODE] for($i=0; $i<some number; $i++) …
