Hi,

In onChange client script i can't able to get the error message please help me out the reason.

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    var currentDate = new Date();

    var selectedDate = new Date(newValue);

    if (selectedDate > currentDate) {

        g_form.showErrorBox('Invalid Date', 'Future dates are not allowed.');

        g_form.setValue('issue_date', ''); // Replace 'your_date_field' with the actual field name

    }

}

Hi,

This kind of date comparison will not work, because it's different in the formatting.

the "new Date()" will return something like this: "Mon Dec 11 2023 07:28:47 GMT+0100..."

while the newValue probably will return something like: "2023-01-31 Tue 04:33:54"

I would recommend sending the existing date (newValue) to a scriptInclude and do the comparison serverside, then return true/false back from the function, and use the returnvalue from the function in your clientscript.

HI @kranthi2 ,

Please use "  g_form.addErrorMessage('message goes here'); " not g_form.showErrorBox('Invalid Date', 'Future dates are not allowed.');

Hi,

if it is simple validation then you can use UI Policy:

Hi @kranthi2  You can achieve this with UI Policy like below

Alternatively you can use the client script below

   var currentDate = new Date().getTime(); // todays date

    var refreshDate = new Date(g_form.getValue('date')).getTime(); // user selected date

    if (refreshDate > currentDate) {

        var message = 'Cannot select Future Date';

        g_form.clearValue('date');

        g_form.showErrorBox('date', message);

    }
