How to use synchronous call on service portal.

[Bosco Sahayaraj]

Hi Team,

I want to do date validation. Here getXMLWait() is not working on service portal. Any other alternative solution for this. Because i can not use asynchronous glide ajax, it will not wait for the service response. I am keeping my code below.   I am sure that my script include is working good.

function onSubmit() {

var startDate = g_form.getValue("start");

var endDate = g_form.getValue("end");

if(startDate != undefined && startDate != '' && endDate != undefined && endDate != ''){

var validation = new GlideAjax('OLA_DongleDateValidation');

validation.addParam('sysparm_name','ola_Startvalidation');

validation.addParam('sysparm_Start',startDate );

validation.addParam('sysparm_End',endDate );

//validation.getXMLWait(); not working in portal

//var answer = validation.getAnswer();

validation.getXML(HelloWorldParse);

var valid = new GlideAjax('OLA_DongleDateValidation');

valid.addParam('sysparm_name','ola_currentdatevalidation');

valid.addParam('sysparm_Start',startDate);

valid.addParam('sysparm_End',endDate );

valid.getXMLWait();

var answer1 = valid.getAnswer();

alert(answer1);

valid.getXML(HelloWorld);

    }

function HelloWorldParse(response) {  

    var answer = response.responseXML.documentElement.getAttribute("answer");

    if(answer = false){

    alert("End date should not be before start date");

    return answer;

    }

}

    function HelloWorld(response) {  

    var answer = response.responseXML.documentElement.getAttribute("answer");

    if(answer = false)

    {

    alert("Start date should not be a past date");

    return answer;

    }

    }

Hi Bosco,

If you want to validate input date of RP (using client script - portal), you can use the moment.js lib.

This is example code:

function onSubmit() {

  g_form.hideAllFieldMsgs("error");

  var isValid = true;

var formatDate = getFormatDate();

var today = moment();

      var starts = moment(g_form.getValue('start_date'), formatDate);

if (starts.isBefore(today)) {

            g_form.showErrorBox("start_date", "Start date must be today or a future date!");

            isValid = false;

      }else{

//add anything you want

}

      g_form.submitted = isValid;

      return isValid;

}

function getFormatDate() {

      var formatDate = "DD-MM-YYYY";

      try {

              if (g_user_date_time_format.indexOf("MM-dd-yyyy") !== -1) {

                      formatDate = "MM-DD-YYYY";

              } else if (g_user_date_time_format.indexOf("dd/MM/yyyy") !== -1) {

                      formatDate = "DD/MM/YYYY";

              } else if (g_user_date_time_format.indexOf("yyyy-MM-dd") !== -1) {

                      formatDate = "YYYY.MM.DD";

              }

      } catch (err) {

              formatDate = "DD-MM-YYYY";

      }

      return formatDate + " HH:mm:ss";

}

Hope this will helpful!

The answer is that you don't.  Synchronous calls are not available on portal, so you are stuck with async.  Your goal is to check a remote record's value when you submit the request.  Instead, set a hidden value on your request to true or false based on an onChange to the given field(s).  Here is an example that checks for a manager:

function onChange(control, oldValue, newValue, isLoading) {
	if(newValue != ''){
		var usr = g_form.getReference('requested_for', getManagerInfo);
	}
}

function getManagerInfo(usr){
	if(usr.manager == ''){
		g_scratchpad.hasManager = false;
	}else if( usr.manager.active == false){
		g_scratchpad.hasManager = true;
	}
}

Then use an onSubmit to check if that value is true or false.

function onSubmit() {

	var manager = g_scratchpad.hasManager;
	if (manager){
		alert('Please provide Requested for user with a valid Manager.');
		return false;
	}
}
