Due Date Field GlideDateTime comparison

[Anubhav24]

Hi All,

We have a field Due Date on catalog task form and I have to compare the old and new values on change of due date field in a onChange Client Script.

I am simply getting the value using g_form and then doing the equal to check , do I need to convert these dates or a simple comparison is fine.

Thanks in advance.

simply comparing won't work

If you want to compare 2 date/time in client script, take this as example where I am comparing the start and end dates

function onSubmit() {
	//Type appropriate comment here, and begin script below

	g_form.hideErrorBox('start_date');
	g_form.hideErrorBox('end_date');

	if(g_form.getValue('start_date') != '' && g_form.getValue('end_date')){
		var start = new Date(g_form.getValue('start_date')).getTime();
		var end = new Date(g_form.getValue('end_date')).getTime();
		if(end < start){
			var message = 'Please give valid start and end dates';
			g_form.showErrorBox('start_date', message);
			g_form.showErrorBox('end_date', message);
			return false;
		}

	}
}

Hi @Ankur Bawiskar ,

This piece of code will not work :

  if (oldValue != newValue) {

alert ('date is changed');

}

Currently I have this code and it is working as I expect it to execute.

Please advise accordingly

@Anubhav24 

okay so you want to compare oldValue and newValue

then oldValue != newValue will work and you should be good to use that.

Just a discussion point out here @Ankur Bawiskar  , I had this confusion of whether to use getTime or not that is why I created this thread however  if oldValue and newValue will work in comparison will something like you posted in your piece of code for start date and end date , not work unless it is converted to milliseconds using getTime function ? 

Also comparing oldValue and newValue is that a good and recommended practice?
