How to find if current date has passed the due date in ServiceNow client scrip?t

[Snehal13]

My requirement : I have a field on the form as 'Due Date'  and want to check if current date has past this due date or not when user opens the form

Accordingly,  need to show infoMessage on the form.

@Snehal13 

you can use onLoad client script and compare like this

function onLoad() {
    var nowDateTime = new Date().getTime();
    var dueDate = new Date(g_form.getValue('due_date')).getTime();
    if (dueDate < nowDateTime) {
        g_form.addInfoMessage('Your message here');
    }
}

Another way is to use UI policy

One correction i missed to ask in.the original question

If current date is past the due date,  I need to update a field on the form. So can you suggest a server side solution as well

@Snehal13 

you can use a before update business rule and check this

var nowDateTime = new GlideDateTime().getNumericValue();
var dueDateTime = new GlideDateTime(current.due_date).getNumericValue();

if (dueDateTime < nowDateTime) {
    current.u_field = 'your value';
}

Hi @Snehal13 ,

create a display Business rule

with script

(function executeRule(current, previous /*null when async*/ ) {

    // Add your code here
    g_scratchpad.isPastDueDate = GlideDateTime.subtract(current.due_date.getGlideObject(), new GlideDateTime()).getNumericValue(); //replace due_date with your field name

})(current, previous);

replace due_date with your field name if required

create a client script of your requirement onLoad or onChange
I have created a onload client script for testing (use the scratchpad object to know if the due date has passed and directly display the message

function onLoad() {
    //Type appropriate comment here, and begin script below
    if (g_scratchpad.isPastDueDate > 0) {
        g_form.addErrorMessage('already passed due date')
    }
}

 result
