Hi @Ajay Singh2 

if it onchange then use onchange method as per your requirement and try below code

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if(newValue !=''){ //newValue is onchange of your field

 var ga = new GlideAjax('myScriptUtils');
 ga.addParam('sysparm_name', 'nameOfInstance');
 ga.getXML(InstanceName);
}
 function InstanceName(response) {
 var answer = response.responseXML.documentElement.getAttribute("answer");
 g_form.setValue('short_description', answer); 
 }  
}

Script Include: 

var myScriptUtils = Class.create();
myScriptUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

nameOfInstance:function() { 

var instanceName = gs.getProperty('instance_name');

return instanceName; 

} ,

type: 'myScriptUtils'
});

@Ajay Singh2 You can use below client script and script include

Script include : instanceDetails

In below script you can replace the actual keyword present in your instance name like dev, qa & prod under indexOf function

var instanceDetails = Class.create();
instanceDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getInstanceName:function(){
		var instanceName = gs.getProperty('instance_name');

		if (instanceName.indexOf('dev') > -1)
		return "Dev";

		if (instanceName.indexOf('qa')  -1)
		return "QA";

		if (instanceName.indexOf('prod') > -1)
		return "Prod";

	},
	

    type: 'instanceDetails'
});

Client script 

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var getInstanceDetails = new GlideAjax('global.instanceDetails');
    getInstanceDetails.addParam('sysparm_name', 'getInstanceName');
    getInstanceDetails.getXML(InstanceName);

    function InstanceName(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer")
        g_form.setValue('instance_name', answer); // where you want to set the instance name set in that field
    }
    

}
