[pallav_nagar]

Please assist with an OnChange Client Script for below scenario:

Scenario 

When Completion Status is changed to Completed, automatically populate the Completion Date with today's date.

If status changes to another value, the date is cleared.

Hi @pallav_nagar 

Here is a community article that explains how to do the date time scripting - this should help you out:

@pallav_nagar ,Use the following script and replace the variables with your actual values and fields

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    // Replace 'Completed' with the actual value if the field is a Choice field
    if (newValue == 'completed') {

        var currentDateObj = new Date();
        var currentDateUsr = formatDate(currentDateObj, g_user_date_time_format);

        g_form.setValue('completion_date', currentDateUsr);

    } else {

        // Clear the Completion Date
        g_form.clearValue('completion_date');
        // Alternatively:
        // g_form.setValue('completion_date', '');

    }
}

If my response helped, mark it as helpful and accept the solution.

Thanks,

Hi @pallav_nagar 

Try with it:

Create an onChange Client Script configured for your Completion Status field.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
if (newValue === 'completed') {
var today = new Date();
g_form.setValue('u_completion_date', formatDate(today, g_user_date_format));
} else {
g_form.clearValue('u_completion_date');
}
}
