How to retrieve multiple values using GlideAJAX?

[hyperjam]

Using GlideAjax single call I expect to return multiple data about user and set it on the request form. However, I'm slightly confused with the returning of multiple values. Below script was a try, but not successful. Any suggestions on how to improve and optimize the below scripts?

client-side script

function onLoad() {

    var usr = g_form.getValue('open_on_behalf_of');//getting user sys_id

      var ga = new GlideAjax('GetUserData'); // with this single call i want to receive various user data like user company, division, location and etc.

      ga.addParam('sysparm_name', 'getUserInfo');

        ga.addParam('sysparm_user', usr);

        ga.getXML(AnswerParse);

  function AnswerParse(response) {

  var answers = response.responseXML.documentElement.getElementsByTagName('usr_comp');     // not sure what to receive here

  for (var i = 0; i < answers.length; i++) {

  g_form.setValue(company,answers[i].getAttribute('result'));

  g_form.setValue(company,answers[i].getAttribute('result'));

      }         }      

}

server side script include

var GetUserData = Class.create();

GetUserData.prototype = Object.extendsObject(AbstractAjaxProcessor, {

  getUserInfo: function() {  

              var usr = this.getParameter('sysparm_user');

              this._getComp(usr);

      },

  //query user company

    _getComp: function(usr) {    

          var cp = new GlideRecord('sys_user');

          cp.addQuery('sys_id',usr);

          cp.query();

          if(cp.next()) {    

              var core_comp = cp.company;

                  var glide = new GlideRecord('core_company');

                glide.addQuery('sys_id',core_comp); // query user company

                      glide.query();

                      if(glide.next()){

                      var usr_comp = glide.name;

                      var company = this.newItem('usr_comp');

                    company.setAttribute('result',usr_comp);

        }

        else {

    return '';     }

          }

    else { return '';}   },

      _getDiv: function(usr) {    

          var gr = new GlideRecord('sys_user');

          gr.addQuery('sys_id',usr);

          gr.query();

          if(gr.next()) {    

              var division = gr.u_division;

                      var glide = new GlideRecord('u_division');

                      glide.addQuery('sys_id',u_division); // query user division

                      glide.query();

                      if(glide.next()){

                      glide.query();

                      if(glide.next()){

                      var usr_div = glide.name;

                      var div = this.newItem('usr_div');

                      division.setAttribute('result',usr_div);

                                }

    else { return '';     }  

},

      type: 'GetUserData'

});

Hi Chuck,

I need to call two functions which are defined in same script include.

Can you please suggest me how to do it?

Hi Shamma,

Your script include can have multiple functions. When you make a GlideAjax call, the sysparm_name parameter determines which function gets called.

var ga = new GlideAjax('MyScriptIncludeAjax');

ga.addParam('sysparm_name', 'myFunction');

ga.addParam('sysparm_anotherparm', g_form.getValue('field'));

ga.getXML(myCallBack);

In this example, MyScriptInclude is the name of the script include, myFunction is one of the functions in that script include, and I pass an optional additional parameter that myFunction can use with this.getParameter('sysparm_anotherparm').

If you have another function in your script include, just change the name on the line that sets up the sysparm_name attribute. That's the only 'hard-coded' piece to GlideAjax.

Hi Chuck,

This is my onSubmit Client script which is calling two GLIDEAJAX function:

function onSubmit() {

  var ga = new GlideAjax('AjaxFunctions');

      ga.addParam('sysparm_name','checkServerApplications');

      ga.addParam('sysparm_servers',g_form.getValue('affected_servers'));

      ga.getXMLWait();

  if (ga.getAnswer() == 'noapp'){

  return true;

  }

  else{

  g_form.clearMessages();

  g_form.addErrorMessage(ga.getAnswer());

  return false;

  }

  var cdt = g_form.getValue('end_date');

  var ajax = new GlideAjax('AjaxFunctions');

  ajax.addParam('sysparm_name', 'addDateTimeAmount');

  ajax.addParam('sysparm_end_date', cdt);

  ajax.getXMLWait();

  var res = ajax.getAnswer();

  if(res == 'true')

  {

  g_form.showErrorBox('end_date', 'Please select an end date at least three days from now.', true);

  return false;

  }

  else

  {

  return true;

  }

}

This script is not working however if I comment anyone GLIDEAJAX call then it works fine.However both of them are not working together.

Please suggest how to proceed further?

Hi Shamma,

Take a look at episode 23 of TechNow we did last month. It talks about this almost exactly.

Hi Chuck,

Thank you so much!!

It is resolved now. I mentioned some conditions in Client scripts and it worked.

Thank alot!

Code mentioned below:

function onSubmit() {

var datetime = addDateTimeAmount();

var checkserver = checkServerApplications();

if(datetime == false || checkserver == false)

{

  return false;

}

else if(datetime == true && checkserver == true)

{

  return true;

}

}

function addDateTimeAmount() {  

  var cdt = g_form.getValue('end_date');

  var ajax = new GlideAjax('AjaxFunctions');

  ajax.addParam('sysparm_name', 'addDateTimeAmount');

  ajax.addParam('sysparm_end_date', cdt);

  ajax.getXMLWait();

  var res = ajax.getAnswer();

  if(res == 'true')

  {

  g_form.showErrorBox('end_date', 'Please select an end date at least three days from now.', true);

  return false;

  }

  else

  {

  return true;

  }

}  

function checkServerApplications() {  

  var ga = new GlideAjax('AjaxFunctions');

      ga.addParam('sysparm_name','checkServerApplications');

      ga.addParam('sysparm_servers',g_form.getValue('affected_servers'));

      ga.getXMLWait();

  if (ga.getAnswer() == 'noapp'){

  return true;

  }

  else{

  g_form.clearMessages();

  g_form.addErrorMessage(ga.getAnswer());

  return false;

  }

}
