Get API data asynchronously in portal widget.

[M_Taimoor Jawai]

Hi,

I am creating a chart.js widget and it is getting its data from servicenow table using REST api. I want that when data changes in table and I save it. It should automatically be shown on widget without loading the page. Any suggestions?

CLIENT SCRIPT

api.controller=function($scope) {
/* widget controller */
var c = this;

$scope.labels = c.data.labels;

$scope.data = c.data.datas;
};

SERVER SCRIPT:

(function() {
/* populate the 'data' object */
/* e.g., data.table = $sp.getValue('table'); */

data.labels = [];
data.datas = [];
var request = new sn_ws.RESTMessageV2();
request.setEndpoint('https://dev60543.service-now.com/api/now/table/u_story_2_dashboard?sysparm_fields=u_data&sysparm_lim...');
request.setHttpMethod('GET');

//Eg. UserName="admin", Password="admin" for this code sample.
var user = 'admin';
var password = 'Qmyl91I!K/Ib';

request.setBasicAuth(user,password);
request.setRequestHeader("Accept","application/json");

var response = request.execute();
var res =JSON.parse(response.getBody());
//var ar = JSON.parse(res)
//.u_data;
var result = res.result;
for(var i = 0; i<result.length;i++){

data.labels.push((JSON.parse(result[i].u_data).label).toString());
data.datas.push(JSON.parse(result[i].u_data).data);
}
})();
