Post Selection JavaScript

About Post Selection JavaScript

Lookup fields can perform additional operations using JavaScript. The code runs whenever the user selects a target record in an object Form.

Post Selection JavaScript is similar in nature to Form Scripting and Field Scripting, but it provides additional variables that are pertinent to a Lookup field.

Working with Post Selection Scripts

Follow these steps to add or change scripting for a Lookup field:

1. Click > Customization > Objects > {object} > Fields
2. Click the name of the Lookup field.
3. Enter or change the code in Post Selection JavaScript.
4. Click the Save button.

Lookup Variables

In the JavaScript code, the following variables are available:

• objectId - The identifier for the Object
• id - The identifier for the selected record
• name - The label of the selected record, as defined by the Record Identifier configured for the object.

• Field Name and Field Value syntax
• Use AJAX and REST to communicate with the platform in JavaScript code.
• Global JavaScript Variables
• Accessing Additional Lookup Variables in a Form

Examples

Display the Label of the Selected Record

This example uses the name variable to display the label of the record.

<syntaxhighlight lang="javascript" enclose="div">

alert("You have selected record: " + name); </syntaxhighlight>

Copy a Field from Another Record

This code accesses the record targeted by a Lookup, retrieves a field value, and places it into the current form. Here, the current record is an OrderItem. When the user selects the Order the item is part of, this code retrieves the Order number and stores it in the current record.

Here, an AJAX call accesses a platform REST API to retrieve data.

<syntaxhighlight lang="javascript" enclose="div">

$.ajax({

 type: 'GET', 
 url: '/networking/rest/record/'+objectId+'/'+id+'?alt=json', 
 async: false,
 dataType: 'json', 
 success: function(response) { 
   // Get a value from the target record.  Set it in current record.
   var value = response.platform.record.somefieldname; 
   setTextFieldValue(_sdForm, "myfieldname", value);
 }, 
 error: function(xhr) { 
   var response = eval( "(" + xhr.responseText + ")" ); 
   alert(response.platform.message.description); 
 } 

}); </syntaxhighlight>

Considerations

• The code adds the record ID to the object ID, and uses the REST API:record Resource to retrieve data from the target record.
• The resource URL includes the query param alt=json, which tells the platform to return the data in the standard JavaScript data format.
• The datatype parameter is set to json, as well. That setting tells the JavaScript code how to parse the returned data.
• Since the code runs in an object Form, the copied data is immediately visible when the lookup is made.
• The JavaScript is always executed in the context of a Form. Fields referenced in the JavaScript must be part of any form in which the user can do a Lookup. (Their field properties can be set to "hidden", but they should not be removed from the form.)
• The JavaScript functions that can be used to set and get form fields are shown below.

JavaScript Field Type Reference

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. Learn more: Localization#JavaScript Programming

Note: JavaScript functions mentioned in the table does not support Web Forms.
