Hello, in this study that I did over two days, I created a catalog item with 3 string fields, free text type, so that the person can type the incident number and thus bring up the short description and the incident description. I am aware that there are ways to do this without having to create a catalog client script or an include script, but I did it this way for a challenge that was proposed, so that I could go deeper and better understand the relationship between a GlideAjaz and catalog client script.
Script Include:
var DetalhesIncident = Class.create();
DetalhesIncident.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getDescription: function() {
var getIncident = this.getParameter('sysparm_incident');
var obj = {};
var inci = new GlideRecord('incident');
inci.addQuery('number', getIncident);
inci.query();
if (inci.next()) {
obj.campo2 = inci.description.getValue();
obj.campo3 = inci.short_description.getValue();
}
var log = JSON.stringify(obj);
//gs.addInfoMessage('Retorno objeto: ' + log + ' | Retorno parâmetro: ' + getIncident);
return JSON.stringify(obj);
},
type: 'DetalhesIncident'
});
Catalog Client Script:
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var ga = new GlideAjax('DetalhesIncident'); // Nome do Script Include
ga.addParam('sysparm_name', 'getDescription'); // Método
ga.addParam('sysparm_incident', newValue); // Parâmetro correto
ga.getXML(callback);
function callback(response) {
// Obtendo a mensagem (comments) do XML de resposta
var comments = response.responseXML.documentElement.getAttribute("answer");
// Convertendo a string JSON em um objeto
var obj = JSON.parse(comments);
// Atribuindo as mensagens às variáveis
var campo_2 = obj.campo2; // "Unable to access the shared folder. Please provide access."
var campo_3 = obj.campo3; // "Unable to access"
g_form.setValue('campo_2', campo_2);
g_form.setValue('campo_3', campo_3);
}
}
The challenge and reaching the result this way was fun. I believe there are ways to create better and more dynamic code, but for now I think this works very well.
