Creating a 2d associative array javascript (same as a php assoc array)

I am trying to create an array in javascript which will allow me to access data like this:

var name = infArray[0]['name'];

however I cant seem to get anything to work in this way. When i passed out a assoc array from php to javascript using json_encode it structured the data in this way. The reason why i have done this is so i can pass back the data in the same format to php to execute an update sql request.

Solution

  • JavaScript doesn't have associative arrays. It has (numeric) arrays and objects.

    What you want is a mix of both. Something like this:

    var infArray = [{
    name: 'Test',
    hash: 'abc'
}, {
    name: 'something',
    hash: 'xyz'
}];

    Then you can access it like you show:

    var name = infArray[0]['name']; // 'test'

    or using dot notation:

    var name = infArray[0].name; // 'test'
