How to access Json

Question

I am trying to read from a JSON array with a nested array which has its value name spaced out. So I get an error whenever I run the code.

var error = [
    {
        "LessonName":"Understanding Multiplication",
        "LessonID":"13343",
        "no of questions":[{"Locked":"31","Unlocked":5}]
    },

    {
        "LessonName":"Finding Unknown Values ",
        "LessonID":"13424",
        "no of questions":[{"Locked":"34","Unlocked":5}]
    }
]


function jsd(){
    document.write(error[0].LessonName);
    document.write(error[0].'no of questions'[0].Locked);
}

document.write(error[0]."no of questions"[0].Locked); Doesn't seem to display.

1.**First** of all don't make space between the keys."no of questions". 2. **Secondly** the `error[0].Locked` doesn't exists. error[0]["no of questions"][0].Locked Does exists — Javasamurai, Oct 06 '16 at 10:27

You may use a property accessor with brackets for the string.

error[0]['no of questions'][0].Locked

You must use this syntax for strings with spaces.

document.write(error[0]['no of questions'][0].Locked);
