    glideDateTime.addParam("sysparm_name", "currentDateTime");

    //glideDateTime.getXMLWait();

    glideDateTime.getXML(getResponse);

    //var answer = glideDateTime.getAnswer();

    function getResponse(response) {

        alert('Hi121');

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

        if (g_form.getValue('state') == '2') {

            alert('Hi' + answer);

            g_form.setValue('u_hold_start', answer);

            g_form.setValue('u_hold_end', '');

                g_form.setValue('u_hold_end', answer);

            }

        }

    }

}

script include:-

var DOMSPOAjaxUtils = Class.create();

DOMSPOAjaxUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    currentDateTime: function() {

        var glideRecord = new GlideDate();

        var gDate = glideRecord.getByFormat('MM/dd/YYYY hh:mm:ss a');

  gs.log('Hi3242342'+gDate);

        return gDate;

    },

    type: 'DOMSPOAjaxUtils'

});

@Narayana Swamy GlideAjax call is an asynchronous operation and if you are using it in the onSubmit client script it is quite possible that the form is already submitted by the time response comes from the Server, hence the values you are setting using g_form.setValue are not reflecting on the form.

If you wish to perform some validation on onSubmit using a client script, I recommend you refer to the article https://www.servicenow.com/community/developer-articles/async-validation-in-onsubmit-catalog-client-... and apply the same approach.

Hi @Narayana Swamy 

The issue is most likely because the submit action occurred before the value was returned in your GlideAjax call. These lines indicate that g_form.setValue was not reached.

It appears that you're setting the value of the u_hold_end field based on the state field. To address this, you can change your client script from OnSubmit to OnChange on the State field.

Hello @Narayana Swamy ,

The issue you're facing is due to the asynchronous nature of GlideAjax. The g_form.setValue is being executed before the GlideAjax response is received. To resolve this, you need to ensure that the form submission waits until the GlideAjax response is received. Here's how you can do it:

Client Script: 

function onSubmit() {
g_scratchpad.flag = false;
var glideDateTime = new GlideAjax("DOMSPOAjaxUtils");
glideDateTime.addParam("sysparm_name", "currentDateTime");
glideDateTime.getXML(getResponse);

function getResponse(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
if (g_form.getValue('state') == '2') {
g_form.setValue('u_hold_start', answer);
g_form.setValue('u_hold_end', '');
} else {
if (g_form.getValue('u_hold_start') != '') {
g_form.setValue('u_hold_end', answer);
}
}
g_scratchpad.flag = true;
}

while(!g_scratchpad.flag) {
// Waiting for the response
}
return true;
}

Script Include: 

var DOMSPOAjaxUtils = Class.create();
DOMSPOAjaxUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
currentDateTime: function() {
var glideRecord = new GlideDate();
var gDate = glideRecord.getByFormat('MM/dd/YYYY hh:mm:ss a');
return gDate;
},
type: 'DOMSPOAjaxUtils'
});
