Validation on Date field to allow users to only select upto 7 days in future.

[Sai Sachi]

Need to create a client script to validate that date I enter there should not be more than 30 days from today, There is another field called Impact. Is user selects any impact than date should not be more than 7 days from today.

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

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

Kind regards,

Hi,

Here is an example of a no code solution.

You can use a ui policy with condition like below and in the script throw the error.

Hi Sai,

You can do this using 2 UI policies as well. No need of using client script.

UI Policy for Impact is empty

Condition 1: Impact is empty AND //you can remove this condition if not needed.

Condition 2: Date before Today OR // My guess is you dont need dates from the past

Condition 3: Date relative after 30 days from now

UI Policy for Impact is NOT empty

Condition 1: Impact is empty AND //you can remove this condition if not needed.

Condition 2: Date before Today OR

Condition 3: Date relative after 7 days from now

Add below script(In Script section select Run Script is True and add code in Execute if True) in both the policies to clear the date field value and to show error message.(if needed)

function onCondition() {

g_form.clearValue('date_field_name');
g_form.showErrorBox('date_field_name', 'Select a date from today upto the next 30 days', 'error');

return false;
}
