How to access custom fields in javascript?

I have Account with both standard and custom fields. I use the default Page Layout to display and edit any acc. It is necessary to populate some of fields in javascript, so I need access to each of them.

Standart Account fields have a readable ids, such as acc1, acc15, acc16 (see attachments). They are the same for each account.

But custom fields have unique ids, so I cant identify them in DOM (attachments)

What is the best to have access to custom fields on standard Account Page Layout? Thanks a lot.

  • Do you have a Visualforce Page for this already?

  • Do you want to do this purely in javascript or do you have a controller that you can utilise? Sep 18, 2014 at 6:22
  • I already have a controller and I could utilize this. Sep 18, 2014 at 6:30
  • Can you please edit the question and post the code you already have?

In general there are a lot of solution for prepopulating fields on the standard layout page.

As you can see there are some solutions for this problem. You decide what you are taking.

  • Thank a lot! As I understand many of these approaches solve problem of pre-populating (on page load). But how to populate values (retrieved using ajax) into custom field ids on already loaded page? Good luck you too) Sep 18, 2014 at 9:59
  • @AdelNazirov If you have got ID's you can set these values easily with Javascript using access to the field ID: document.getElementById('XXXXXX').value = XX for the input field for example. Sep 18, 2014 at 10:05

Without your code its really hard to suggest anything...

Depending on your requirement:

  1. A simple Document.getElementByID may work
  2. ActionFunction can also be used to invoke controller methods from JavaScript
  3. You can also use @RemoteAction

For code example of these refer to my Blog post VISUALFORCE: PASSING VALUES FROM JAVASCRIPT TO CONTROLLER

The ID values rendered into Visualforce pages for custom fields are hard to get hold of and vary from org to org.

For purely client-side JavaScript I've resorted to basing the logic on the label text of a field. The data value is in a td of class dataCol and the label is in a td of class labelCol. So you can find the label and then find the data value input field in the peer td.

It is possible at some effort to get the field ID values using the tooling API (or some hacks) - see Querying Custom Object and Field IDs via Tooling API. So you could do this in your controller and then reference those field ID values in your Visualforce JavaScript logic.
