Apparently I have use asynchronous GlideAjax in onSubmit client script to validate the fields before submit the form which doesn't work right. Keep in mind that I am creating in scoped application, not global. If the box variable is missing, it trigger alert and prevent user from submit by using return false. However in this case, when I click submit form, it does trigger alert but then it close the form(it doesn't submit form at all) instead of staying in same form to fix it and resubmit it. Can anyone give me sample codes of how to do synchronous GlideAjax in onSubmit script? This is what I got for asynchronous GlideAjax,
in client script,
function onSubmit() {
var getExtReqBy = g_form.getValue('u_ext_reqby_lookup');
var ga = new GlideAjax('VerifyExternalCustomer');
ga.addParam('sysparm_name','checkCompany');
ga.addParam('sysparm_item',getExtReqBy);
ga.getXML(showResponse);
function showResponse(response) {
var typeOfRequest=response.responseXML.getElementsByTagName("Type");
var getAnswer = typeOfRequest[0].getAttribute('getAnswer');
if(getAnswer == 'no'){
alert('External customer does not have company name. Please update the company name before submit this form');
return false;
}
}
}
In Script Include,
var VerifyExternalCustomer = Class.create();
VerifyExternalCustomer.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
checkCompany: function(){
var requestedBy = this.getParameter('sysparm_item');
var getAnswer;
var gr = new GlideRecord('x_ibmdc_case_manag_ext_users');
gr.addQuery('sys_id', requestedBy);
gr.query();
if(gr.next()){
if(gr.u_company == ''){
getAnswer = 'no';
}else{
getAnswer = 'yes';
}
}
var typeOfRequest = this.newItem("Type");
typeOfRequest.setAttribute("getAnswer", getAnswer);
},
type: 'VerifyExternalCustomer'
});
