Referencing Form Fields in JavaScript

From AgileApps Support Wiki

Jump to: navigation, search

JavaScript is a powerful language that can do many things. But one of it's most common uses is to dynamically modify the behavior of Forms, using Form Scripting and Field Scripting.

Referencing the Current Form

In the HTML document object model (DOM), the current form is named _sdForm.
This line of code gets a reference to it and puts it in the form variable:

var form = _sdForm;

Accessing Fields in the Current Form

To find the name of a field in the platform:

  1. Go to GearIcon.png > Customization > Objects > {object} > Fields
  2. Find the label of the field you're interested in
  3. Get its name from the Field Name column
    That name can then be used in the JavaScript code.

All fields can be accessed using the platform's JavaScript functions, as described in the Field Types section below. The most commonly accessed field types (TextField, TextArea, Date, DateTime, Time, and URL) can also be accessed using _sdForm[0]. For example, this line of code gets a reference to the first_name field, and puts it in the variable fName_field:

var fName_field = _sdForm[0].first_name;

Fields have two properties that you can access in JavaScript:

  • name: the name of the field
  • value: the value of the field

So this line retrieves the value of the field:

var fName = fName_field.value;

As does this longer version:

var fName = _sdForm[0].first_name.value;

Other fields can be accessed using the platform's JavaScript functions.
For a complete list, see the Field Types section below.

Updating Fields in the Current Form

The method used to update a field depends on the field type. All of the methods have the general form:

set...Value(_sdForm, field, value);

Below are some examples of common methods. (The section that follows contains a complete list.)

setTextFieldValue(_sdForm, "first_name", "Adam");

setPickListValue(_sdForm, "first_name", "Adam");

setMultiPickListValue(_sdForm, "first_name", ["new","closed"]);
    // value is an array of strings

setRadioButtonValue(_sdForm, "first_name", "Adam");

setCheckboxState(_sdForm, "first_name", true);  // checked
setCheckboxState(_sdForm, "first_name", false); // unchecked

setLookupValue(_sdForm, "project_number", "123456", "My Project");
    // where 123456 is the record ID of the target record
    // "My Project" is the value of the record locator field(s) for that record

Note: To view the field type reference in the new AgileApps user interface, see JavaScript Field Type Reference for New AgileApps User Interface.

The following table shows how to access and update the different field types, where:

  • _sdForm is the variable that references the current form
  • field is a string containing the name of the field
    (as with all strings, literal values must be in quotes)
  • value is a value you specify (generally a string)
  • value is language keyword, typed exactly as shown--as in this line,
    for example, which gets the value from a field called email_address:
_sdForm.email_address.value

Note:
Form data is in User Format. Data entered into the Form must be in that format, as well. Data going to and from the platform, on the other hand, must be in Database Format.
