How to check if Date field is empty

davilu · ‎12-05-2017

Hi Community,

This is kind of a silly question, but I'm writing a client script that checks to see if a date field is empty. If it is empty I want it to clear a couple other fields:

var start = g_form.getValue('from');

var end = g_form.getValue('to');

if(start=='' || null) {

g_form.setValue('year', '');

g_form.setValue('month', '');

g_form.setValue('day', '');

}

Right now, when I delete the date field, the other fields don't clear out. However, if I delete the date field and press the space bar, the other fields clear out. What's the syntax to see if a date field is empty or not?

Thanks!

I believe it's because we are checking newValue === '' in onChange() function and then returning from there, kindly replace this line

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

to

if (isLoading) {

please try with below script and see if that helps:

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

if (isLoading) {

return;

}

//Type appropriate comment here, and begin script below

if(newValue == ''){

g_form.setValue('year', '');

g_form.setValue('month', '');

g_form.setValue('day', '');

}

Try this:

var start = g_form.getValue('from');

var end = g_form.getValue('to');

if(start == false) {
..
}
