How to call a System Property to the Catalog Client Script?

[Alfiya]

Hi All,

So we have a custom table, there are multiple records in this table and this table has a field called 'name', 

There another field on Catalog item called 'cat_name',Now this 'cat_name' field is a reference field to the above mentioned custom table

So below is the either of the ways we were getting the values of the custom table:

                        1) By using getReference() and then hard coding the value of the 'name' Field to identify the record in the                                catalog item Script in catalog item.

or

                        2) By Hard coding the sysid of that record in the catalog Client Script in the catalog item.

So as hard coding is not recommended, I want to do it with system properties. So for each of this record I want to create a system property and then call this system property to the Catalog Client script.

So as gs.getProperty() can't be used in the catalog client script. How can it be fetched?

I now understand that this can be achieved by using a  script Include, But I'm not sure how this can be done.

Also if there is any other way we can do this, please guide me.

Thanks in Advance..

Hi,

only way is to use GlideAjax and then use gs.getProperty() and return the value

OR

1) create hidden string variable and hide it always

2) in the default value give this

javascript: gs.getProperty('property_name')

3) then you can access the property value using g_form.getValue('hiddenVariableName');

Hi there,

GlideAjax with getXMLAnswer would be the best way to go. Unfortunately, it will be a bit of work 😞
See some info in this article which I wrote a while ago:
Client Side Scripting: Go for GlideAjax (with getXMLAnswer)!

The suggestion from Ankur about a hidden variable wouldn't be that hard to achieve and is a nice workaround. Be aware though: this also actually submits and creates a variable with that value. 

If my answer helped you in any way, please then mark it as helpful.

Kind regards,
Mark
