getDisplayValue() ) gives you the value that is displayed for the field's value. You might think a field's value is what it is, but certain field types can have a disparity between the actual value, and the display value. For example, drop-down fields can have a label as well as a value.

To return multiple values from a function in C, you can either use an array, a structure, or pointers. You can store the values you want to return in an array or structure, and then return its reference (memory address) or modify the values directly using pointers passed as function parameters.

JavaScript does not return multiple values just by calling the function therefore it can be achieved using arrays or objects. To return multiple values from a function using arrays, create an array of the variables that are to be returned and then call the array.

Using an Array

Another way to assign multiple variables using a command's output is to assign the command output fields to an array. In the example, we used the Bash built-in readarray command to read the date command's output. The default delimiter used by the readarray command is a newline character.

If you need the Javascript variable to go through any logic on the server, then checkout LiveView Javascript Hooks, which work very well and you can create GenServer-like LiveControllers that react to client events. Most of the boilerplate is already setup in the included LiveView javascript.

However, GlideAjax is complex and requires creation of both a server-side and client-side script, so in many cases it's just fine to use another asynchronous method (such as GlideRecord ) to retrieve data from the server, when we need to access related records in a Client Script, UI Policy script, or other client-side ...

The g_scratchpad object used for passing information from the server to the client when the client requires information not available on a form. This can be accomplished by creating a business rule to put the information in the g_scratchpad object and accessing the information in a client script.

To pass variable to processing script, similarly to client script, you will need a hidden field but for processing script, you just use the name attribute of input field as variable name. Note that input elements should be placed inside g:ui_form so that its values can be sent to server as form data.

The approach of using an array to return multiple values from a JavaScript function involves organizing the values into an array and then utilizing array destructuring to extract and assign those values to individual variables.
