var itemVue = Vue.component("itemTemplate", {
template: `<span><span class='name'>{{data.FirstName}}</span><span class ='city'>{{data.City}}</span></span>`,
data() {
return {
data: {}
};
}
});
export default {
data (){
return {
employeeData : new DataManager({
url: 'https://services.odata.org/V4/Northwind/Northwind.svc/',
adaptor: new ODataV4Adaptor,
crossDomain: true
}),
query : new Query().from('Employees').select(['FirstName', 'City', 'EmployeeID']).take(6),
fields : { text: 'FirstName', value: 'EmployeeID' },
itemTemplate : function(e) {
return {
