Get value of variable

[Matheus Rissi2]

Hello everyone,

Recently I'm having a lot of difficulty with the following question: I'm having to hide a form field,
But the validation must be done on top of the parent's variables.

But, not the form variables, but those that the user selects on the portal.

How can I do this?

The variable I have to hide (This is the Case Task)

The variable I have to use as validation (This is the Case)

Thanks in advance to everyone who can help me.

Hi @Matheus Rissi2 ,

Write one client script in the child table, send its parent reference to the Server Side using GlideAjax, and use "serversideObj.variables.field_name" to fetch the parent's variable value.

I took a similar kind of example, in my case parent table is Case and this case record is having a variable called priority.

And my child's table is incident. So whenever someone tries to create a child incident to the case then it will check its variable priority value and should display a field called Approver.

Below are my both Server and Client Side Scripts:-

Client Side Script:-

Created one OnLoad Client script on my Child Table (In my example it's Incident Table your's is Case Task Table)

function onLoad() {
//Type the appropriate comment here, and begin the script below
var parent_sysid = g_form.getValue('parent'); 
var ga = new GlideAjax('sendCaseVaribleInfo');
ga.addParam('sysparm_name','sendInfo');
ga.addParam('sysparm_parentSysId',parent_sysid);
ga.getXML(ResponseFunction);

function ResponseFunction(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
alert(answer);
if(answer == 'yes')
{
g_form.setVisible('u_approver',true); // Instead of approver write your hidden field back end value
}
else
{
g_form.setVisible('u_approver',false);
}
}
}

Server Side Code:-

Created one client callable script include.

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

sendInfo: function()
{
var CaseNumber = this.getParameter('sysparm_parentSysId');
var gr = new GlideRecord('sn_customerservice_case');
gr.addQuery('sys_id',CaseNumber);
gr.query();
if(gr.next())
{
if(gr.variables.priority == '4') // Afte variables.addYourVariableBackEndName and built the logic
{
return "yes";
}
else
{
return "no";
}
}
},
type: 'sendCaseVaribleInfo'
});

Please my answer as helpful if it helps!!
