something wrong while getting data from url app made in vue js and axios

trying to replace customer js with
export default[
{ id: 0, name: 'some one', title: 'zero' },
{ id: 1, name: 'test last', title:'one'},
{ id: 2, name: 'test first', title:'two'},
{ id: 3, name: 'test second', title:'three'},
{ id: 4, name: 'test third', title:'four'},
{ id: 5, name: 'test fourth', title:'five'},
{ id: 6, name: 'test fifth', title:'six'}
];
My app is fine while using the above raw json.
since i am trying to get the date using axios in same file as per below code
Something i am missing to get the data into app.
import axios from 'axios';
export default {
data () {
return {
info: []
}
},
mounted () {
axios
.get('http://localhost/json/test.json')
.then(response => (this.info = response))
}
}
for getting data from url into customer.js
not working in case.
while my app.vue is
<template>
<div id="app">
<Autocomplete :items="customers"
filterby="name"
#change="onChange"
title="Look for a customer"

</div>

In most of the cases, response consists of several properties and you will need response.data.
if this didn't work then print the response, using console.log(response) and inspect it such that which key holds the JSON data.

How can I prevent users from selecting multiple answers in my quiz?

The issue that I am having is that once a user selects an answer and then clicks 'Submit Answer' and receives their feedback they are able to continue to click around and select other answers before progressing onto the next question. How can I prevent a user from being able to do that once they submit one answer?

Having skimmed through your JS, I'm assuming that the feedback shows on the same page as the question, rather than a new page resulting from submitting it to a server.
When you display the feedback, add a disabled="disabled" property to the item in question, so that your user can't change it. Alternately, hide the selection and display an <output> element: <output>Your Answer: USA<br />Correct Answer: UK</output>
disable All button after checking answers.
$('button').prop('disabled', true);

Why does not work this code with knockout.js tacken fro jsfiddle?

I took an example of Paged grid from jsfiddle.net ( http://jsfiddle.net/rniemeyer/QSRBR/ ) and put it into one *.html file
But it does not work - I got an error in the browser console:

This code works fine at jsfiddle but why doesn't it work when I put it all together an a single file?

Header name not displaying completely in ag-grid angular 2

I am using ag-grid for Angular 2. In that i have multiple headers like token number. It is not displaying completely. It is just like Token N...
Below is my component.ts
import { Component, OnInit } from '#angular/core';
import{ GridOptions } from 'ag-grid';
import { FlightProcessGridStatusComponent } from '../flight-process-grid-status/flight-process-grid-status.component';
import { FetchedFlightInfoBean } from '../../_model/FetchedFlightInfoBean';
#Component({
selector: 'app-user-home-child',
templateUrl: './user-home-child.component.html',
styleUrls: ['./user-home-child.component.css'],
//providers: [FetchedFlightInfoBean]
})
export class UserHomeChildComponent {
private gridOptions: GridOptions;
private refreshFlag: boolean;
fetchedFltBean: FetchedFlightInfoBean [] = [
{tokenNbr:1, flightNbr:"AY01", flightDate: "12-aug-17", flightBrPoint:"DEL", flightoffPoint:"LKO", nbrPax:2, okEmail:"Y", nonOkEmail:"N", okphn:"Y", nonOkPhn:"N", status:"WAIT"},
{tokenNbr:2, flightNbr:"AY02", flightDate: "6-aug-17", flightBrPoint:"BAN", flightoffPoint:"MUM", nbrPax:4, okEmail:"N", nonOkEmail:"Y", okphn:"Y", nonOkPhn:"N", status:"MISSED-CONNECTION"},
{tokenNbr:3, flightNbr:"AY013", flightDate: "22-aug-17", flightBrPoint:"HEL", flightoffPoint:"PAR", nbrPax:1, okEmail:"N", nonOkEmail:"Y", okphn:"Y", nonOkPhn:"N", status:"FLOWN"}
];
constructor() {
this.gridOptions = <GridOptions>{headerHeight: 48,
rowHeight: 35,
rowSelection: 'single',
enableColResize: true,
onGridReady: (params) => {
params.api.sizeColumnsToFit();
}
};
this.gridOptions.columnDefs = [
{headerName: 'Token Number', field: 'tokenNbr'},
{headerName: "Flight Number", field: "flightNbr"},
{headerName: "Flight Date", field: "flightDate"},
{headerName: "Flight Boarding Point", field: "flightBrPoint"},
{headerName: "Flight Off Point", field: "flightoffPoint"},
{headerName: "NBR of Pax", field: "nbrPax"},
{headerName: "Ok Email", field: "okEmail"},
{headerName: "NonOk Email", field: "nonOkEmail"},
{headerName: "Ok Phone", field: "okphn"},
{headerName: "NonOk Phone", field: "nonOkPhn"},
{
headerName: "Status",
field: "status",
cellRendererFramework: FlightProcessGridStatusComponent,
}
];
this.gridOptions.rowData = this.createRowData();
}
public refreshRowData()
{
this.refreshFlag = true;
alert(`inside refreshRowData`);
let rowData = this.createRowData();
this.gridOptions.api.setRowData(rowData);
}
private createRowData() {
if(this.refreshFlag)
{
alert(`refresh call`);
}
let rowData:FetchedFlightInfoBean[] = this.fetchedFltBean;
/* let rowDataLength = rowData.length;
alert(`${rowDataLength}`)
for (var i = 0; i < rowDataLength; i++) {
rowData.push({
tokenNbr: 1,
flightNbr: "",
flightDate: "",
flightBrPoint: "",
flightoffPoint: "",
nbrPax: 3,
okEmail: "",
nonOkEmail: "",
okphn: "",
nonOkPhn: "",
status: "",
});
}
*/
return rowData;
}
}
next is my html part....
<div style="width: 800px; padding-left: 100px" class="ag-fresh ag-header-cell-label">
<button (click)="refreshRowData()">Refresh Data</button>
<button (click)="autoFit()">AutoFit</button>
<ag-grid-angular style="width: 1000px; height: 1000px;"
[gridOptions]="gridOptions"
enableSorting
enableFilter >
</ag-grid-angular>
</div>
my CSS-
#import url("https://fonts.googleapis.com/css?family=Raleway:400,700");
.ag-fresh {
font-family: "Raleway", "Helvetica Neue", Helvetica, Arial, sans-serif;
font-size: 14px;
}
.ag-fresh .ag-root {
border: none;
}
.ag-fresh .ag-header-container {
background: #fff;
}
.ag-fresh .ag-header {
border-bottom: 2px solid #000;
}
.ag-fresh .ag-header-row {
font-weight: bold;
font-size: 13px;
line-height: 1em;
color: #000;
background: #fff;
border: none;
}
.ag-fresh .ag-ltr .ag-header-cell {
padding: 10px;
border: none
}
.ag-fresh .ag-row {
border-bottom: 1px solid #ddd;
}
.ag-fresh .ag-row:nth-child(odd){
border-top: 1px solid #ddd;
background-color: #f9f9f9;
}
.ag-fresh .ag-row:last-child {
border-bottom: none;
}
.ag-fresh .ag-row:hover {
background-color: #d9edf7;
border-top: 1px solid #aaa;
border-color: #aaa;
}
.ag-fresh .ag-row .ag-cell {
color: #333;
padding: 10px 15px;
}
.ag-fresh .ag-row .ag-cell:focus,
.ag-fresh .ag-row .ag-cell:hover {
font-weight: bold;
background-color: #d0edf3 ;
color:#000;
}
.ag-header-cell-label {
text-overflow: clip;
overflow: visible;
white-space: normal;
}
In my component you can see I have fixed the size of the column using params.api.sizeColumnsToFit(). This allow my columns to display without a horizontal scroll bar. So i am getting complete data in one view.
But now my column-headers are not wraaping up there name. I am not getting the complete name displayed.
For example, If the column-header is Token Number then only "token n..." this part is displayed.
Please help.
