Hi,

g_form.showFieldMsg("u_date_field",'You can not select a Past Date'); 

we need to mention the field on which we need to show field message.

Hi, 

Try Below...It works.

Client Script : Onchange Client Script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    var udt = newValue;
    var ga = new GlideAjax("GetCurrentDateAndTime");
    ga.addParam('sysparm_name', 'GetDate');
    ga.addParam('sysparm_get_date', udt);
    ga.getXML(HelloWorldParse);

    function HelloWorldParse(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        if (answer == '5') {
            g_form.setValue('date_field_name', "");
            return false;
    }
}
}

Script Include

var GetCurrentDateAndTime = Class.create();
GetCurrentDateAndTime.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    GetDate: function() {
        var getNum = this.getParameter('sysparm_get_date');
        var nd = new GlideDateTime();
        if (getNum > nd) {
            return 5;
    },
    type: 'GetCurrentDateAndTime'
});
