What causes the return of undefined when accessing an item from an object?

In order to extract the item "Errors" from the data object provided below:

{Id: 15, Date: "22-02-2019", Time: "22:45", Sport: "Football", Country: "United Kingdom", …}
    Bet: "Win"
    Bookie: "Bet365"
    Competition: "Premier League"
    Country: "United Kingdom"
    Currency: "Euro"
    Date: "22-02-2019"
    Home: "Cardiff"
    Id: 15
    Odds: "1.45"
    Sport: "Football"
    Stake: "5.110"
    Status: "Won"
    Time: "22:45"
    Visitor: ""
    Εrrors: Array(2)
        0: (2) ["date", Array(1)]
        1: (2) ["visitor", Array(1)]
        length: 2
        __proto__: Array(0)
    __proto__: Object

This object is part of an array of objects retrieved as a response from an ajax call to an API endpoint.

$.ajax({
        type: "POST",
        url: "/api/import",
        headers: {"X-CSRFToken": Cookies.get('csrftoken')},
        data: formData,
        cache: false,
        contentType: false,
        processData: false,
        success: function (res) {
        ....}
    })

Accessing rowData["Date"] or rowData["Time"] successfully returns their respective values.

However, when trying rowData["Errors"], I am getting undefined. The reason behind this is unclear - whether it's because the Errors attribute is not found or due to another issue.

The goal is to retrieve the Errors in order to iterate through them and showcase on the webpage.

Mainly experienced with JavaScript for DOM manipulation, this particular challenge has left me puzzled.

Remember the importance of accurate spelling, especially when dealing with words that overlap between English and other languages.

Answer №1

To properly access the "Errors" property, you can utilize square brackets like so:

rowData["Errors"];

Alternatively, if the property name doesn't contain spaces or special characters, you can use dot notation for a simpler approach:

rowData.Errors;
