[Service Portal] How to validate start and end dates in portal

[Paul Bayani]

Hi! Appreciate your advice about how to correctly put a date validation in the servical portal.

What I'm trying to achieve:

There are 2 dates in the portal form:

Start Date

End Date

Validation: The end date should not be prior the start date

I tried that using below client script but it did not work.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var first=g_form.getValue('u_effective_date_of_leave');
var last=g_form.getValue('u_last_worked_day');

if(last<=first){
alert("Last day worked should be on or prior to effective date of leave");
g_form.setValue('u_effective_date_of_leave','');
//Type appropriate comment here, and begin script below
}
}

Anything I'm missing? thanks in advance

Hi there,

Have you considered using a (Catalog) UI Policy to achieve date validations? There's almost no-code needed to achieve date validations this way. Have a look at an article I wrote on this:
No Code date validations thru (Catalog) UI Policies

And a copy/paste from the article:

Comparing two entered dates with each other. Date 2 should not be before Date 1 (image, planned end date should not be before planned start date)

Hello Mark! Thanks for sharing this.

I used the Catalog UI Policy route for the 2 date fields I'm creating (comparing 2 entered dates). So what would I add then in the Catalog UI Policy actions for this one? Like where do I enter the error message.

Thanks,

Paul

Have a look at the article, you can generate the message through the Script fields if true, if false.

No catalog UI policy actions needed.
