[Help] How to create a Pop up error message for a variable in catalog items

[SUDCHAK]

If a variable of type date/ time or just date is created then in the client scripts what should be coded if the user enters previous/future date where the variable accepts only future/previous date, for this an error message should pop up just around the variable field?

Hi @SUDCHAK ,

U can create a UI policy for this mentioning in the condition if date field is before today . Then go to ur script tab n select run for all n under when condition is true u can specify the alert or field message

Thanks,

Hi @SUDCHAK ,

In order to showcase error for a respective field u can try this

g_form.showFieldMsg('variable_name','Enter your message here','error');

Thanks,

Danish

Hi,
This can be done by UI policy without writing any code.

Actually the code that u shared i have already used it but the requirement is to make an error pop up message if wrong date/time or just date entry is made which should appear just below or above the variable field.

Hi @SUDCHAK 
Hi,
You can write

g_form.clearValue("name_of_variable");
g_form.showErrorBox("name_of_variable","You cannot add a past date");

I tried the code that u shared but the error pop up is not shown while trying out the catalog form.
