Hi I'm trying to access an js object property which has an slash "/" in its name.

The object its somthing like:

{
   my/key : "my value"
   // more stuff here...
}

I try the following construction:

myObject["my/key"]

If I try to it in Chrome DevTools it works correctly but when I execute my code i get a beautiful undefined on browser console (using console.log())

has anybody any idea of what's happening? :S

• javascript
• json

• Try using backslash before slash, this could help. – Jan.J Commented Aug 22, 2013 at 12:09
• 1 / is not an illegal character - see stackoverflow./questions/1661197/… for a prehensive description of what is valid. – knolleary Commented Aug 22, 2013 at 12:09
• 2 Pretty much anything can go into property name (including newlines for example a = {}; a["\n"] = 'foo'; works) as long as you enclose it in quotes and use array access operator. JS objects are key-value maps essentially, and keys can be anything. – Mchl Commented Aug 22, 2013 at 12:20

When you enclose the prop name into quotes, it works also in the code:

var obj = {
    'my/key' : 'my value'
};

You can check this at jsFiddle.

I tried your code in Node.js and it is working as expected, as long as the property name is quoted.

Try outputting the exact value of the key ("my/key") that you use to access the value - maybe, you are using a different key there.
