Selected date should be current or onwards. If previous date is selected, it will show an error msg.

Hello everyone,

The requirement is for the user to not be able to select a previous date, if they select a date not of the current date or onwards. It will show a red message saying "Please Select Current Date or On wards".

Is it possible to do using ajax or client scripts if so how should it be done?

Hi @MelvinBulan ,

Please try adding the below script include and the client script, update the name for your "date_variable" in the client script, and see how you go.

Script Include: 

var checkDateUtils = Class.create();
checkDateUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	
	dateDiff: function() {
		var firstDate = this.getParameter('sysparm_first_date');
		var secondDate = this.getParameter('sysparm_second_date') || gs.now();
		
		return gs.dateDiff(secondDate, firstDate, true);
	},

    type: 'checkDateUtils'
});

Client Script - onChange date variable

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

	// Start Date cannot be backdated
	var dateAjax = new GlideAjax('checkDateUtils');
	dateAjax.addParam('sysparm_name', 'dateDiff');
	dateAjax.addParam('sysparm_first_date', newValue);
	dateAjax.getXMLAnswer(processResponse);
}

function processResponse(answer) {
	// If Start Date is in the past (Less than 0) show an error and clear the value
	if(answer < 0) {
		g_form.clearValue('date_variable');
		g_form.showErrorBox('date_variable', 'Date cannot be in the past!');
	} else {
		g_form.hideErrorBox('date_variable');
	}
}

 
Hope this helps!

Hello,

You do not require to write any script. You can achieve this using UI policy
