How to get the refernce/choice field value using Onload and Onchange CS ?

PP12 · ‎01-07-2019

Referring to a thread i tried g_form.getDisplayBox('field_name').value;

but it didn't work in onChange Cs whereas in onLoad it worked for some field, not for all.

getValue() -- gives you the value not the name.

getDisplayValue() is not recommended for client side So,

can anyone give me example for both onload and onchange cs , how to get the value of reference/choice field and display in an alert for testing purpose?

no need to use if condition just simply get the the value and display in alert.

Thank You.

Hello PP,

Missed your previous reply, my bad.

Ok Let me share you a client script and a script include with the same what you wanted to do

Based on your script include code what you are doing is exactly correct. just you need to add a couple of additional parameters to pass the values from the client script to your script include so that it can process and give you back the results

Client Script:

function onLoad(){

var ga = new GlideAjax('clientsidecall');

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

ga.addParam('sysparm_asg_grp',g_form.getValue('assignment_group');

ga.addParam('sysparm_asg_to',g_form.getValue('assigned_to;);

ga.getXML(val1);

function val1(response){

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

alert(answer);

}

Client Script :

var ClientsideCall = Class.create();
ClientsideCall.prototype = Object.extendsObject(AbstractAjaxProcessor, {
Getvalue : function(){
var at = this.getParameter('sysparm_asg_to');
var asg_group = this.getParameter('sysparm_asg_grp');
return at+","+asg_group;
},
type: 'ClientsideCall'
});

Hope that helps

For passing multiple values back to the client script from script include you can also use JSON but the thing you are looking for should work with what i have provided above

Mark this response as correct if that really helps

Thanks,

Siva

Both worked for the caller field in the incident table

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
alert(g_form.getDisplayBox('caller_id').value);
//Type appropriate comment here, and begin script below

}

function onLoad() {
//Type appropriate comment here, and begin script below
alert(g_form.getDisplayBox('caller_id').value);
}
