Please check your instance. I have created a new onchnage client script and script include. It is working as expected.
onChange:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var ga = new GlideAjax('ValidateDate');
ga.addParam('sysparm_name','dateValidation');
ga.addParam('sysparm_date',newValue);
ga.getXML(CallBack);
function CallBack(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
if(answer=='true'){
alert("pls select atleast 48hrs or more from now");
g_form.setValue('lpar_refreshed','');
}
}
}
Script include:
var ValidateDate = Class.create();
ValidateDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {
dateValidation: function(){
return (gs.dateDiff(gs.nowDateTime(),new GlideDateTime(this.getParameter('sysparm_date')), true)/3600<48);
},
type: 'ValidateDate'
});
