Client-side code should not use synchronous AJAX methods (e.g., g_form.getReference, getXMLWait)

Hi,

Need a solution that for client side code,  synchronous AJAX methods should not be used then how we can use some other thing like script include for the requirement.

Script: function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var caller = g_form.getReference('caller_id');
if (caller.vip == 'true')

{
g_form.setValue('urgency','1');
g_form.setValue('impact','2');
}
else
return;
//Type appropriate comment here, and begin script below

}

Please suggest me the solution that how this can be improved by not using g_form.getReference().

I have also tried this by using UI policy but still not getting any appropriate result.

Thanks

Hi 

If you dont want to use getReference , Go with Script include and use GlideAjax to call it. 

Refer the below thread and follow :-

Hi Omkar,

I have tried to write a client sript with script include but no luck.

Please take a look and help me.

Client script:

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

//Type appropriate comment here, and begin script below
var ga = new GlideAjax('chkUserRole');

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

ga.addParam('sysparm_caller',g_form.getValue('caller_id'));

ga.getXML(HelloWorldParse);

function HelloWorldParse(response) {

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

if(answer)

g_form.setValue('impact','2');
g_form.setValue('urgency','1');

}

}

script include:

var chkUserRole = Class.create();

chkUserRole.prototype = Object.extendsObject(AbstractAjaxProcessor, {

chkCallerUserRole: function() {

var caller = this.getParameter('sysparm_caller');

return gs.getUser().getUserByID(caller).hasRole('zTestVIP');

}

});

What should I write for the VIP to check the condition that if the caller is VIP then impact and urgency should set to 2 and 1 respectively.

Thanks

Hi 

In Script include GlideRecord to sys_user_has_role with the caller and get his role and return from script include.

Hi Omkar,

Could you please modify the script.

It will be very helpful.

Thanks
