How to Auto-Populate Fields in a Target Catalog Item from the Source Catalog Item on Link Click

[E555]

Hello,

I would like to auto populate a field in the target catalog item with the request name of the source catalog item when clicking a link within the Description field.

I saw the steps in the post below and created an onLoad client script, but unable to retrieve the value from the previous catalog item:
Pre-populate a record producer form after clicking link on the catalog item

The target catalog item has a Reference field that refers sc_cat_item table. I want to auto-fill this field based on the source catalog item from which the link was clicked.

Has anyone implemented a similar feature or can guide me on how to achieve this?

Thank you!

@E555 

how have you defined the link? have you included some URL parameter in it?

if yes then did you use onLoad catalog client script on your Test Catalog Item inquiry catalog item to get value from url and set in that variable?

if yes then only it will work fine.

If not then you need to create one.

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi @E555 ,

To achieve the functionality of auto-populating a field in the target catalog item with the name of the source catalog item when clicking a link within the description field, you can utilize URL parameters and client scripts. This method allows the source catalog item to pass relevant information to the target catalog item upon redirection.

Modify the description field of the source catalog item to include a clickable link that directs users to the target catalog item. Pass the name or sys_id of the source catalog item as a URL parameter. Here's an example:

<a href="/com.glideapp.servicecatalog_cat_item_view.do?sys_id=<TARGET_CATALOG_ITEM_SYS_ID>&source_item_name=${current.name}">
    Click here to proceed to the next item
</a>

Replace <TARGET_CATALOG_ITEM_SYS_ID> with the sys_id of the target catalog item. The ${current.name} placeholder dynamically inserts the name of the source catalog item.

now 

In the target catalog item, create an onLoad client script to read the URL parameter and populate the desired field. The script retrieves the source item's name from the URL and sets it in the Reference field.

(function executeRule(gForm, gSNC, gUser) {
    // Helper function to get URL parameter by name
    function getParameterByName(name) {
        var url = window.location.href;
        name = name.replace(/[[]/, "\\[").replace(/[\]]/, "\\]");
        var regex = new RegExp("[\\?&]" + name + "=([^&#]*)");
        var results = regex.exec(url);
        return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
    }

    // Retrieve the source item name from the URL
    var sourceItemName = getParameterByName("source_item_name");

    // If the parameter exists, populate the Reference field
    if (sourceItemName) {
        gForm.setValue("reference_field_name", sourceItemName);
    }
})(gForm, gSNC, gUser);

here :The getParameterByName function extracts the source_item_name parameter from the URL.

The gForm.setValue function populates the Reference field (reference_field_name) with the extracted name.
