Question

I am learning mootools. I have an array in following format.
I want to traverse it in for loop but dont know how to do it.

{'apple' : { 'prize' : 10 , 'color' : 'Red' } ,
'banana' : { 'color' : 'red', 'prize' : 20, 'quantity' : 12 } }

I am getting above structure of array from another module thats why i cant change its structure.

Answer 1

Those are objects, not arrays.

Example: http://jsfiddle.net/AkVvY/

var obj = {'apple' : { 'prize' : 10 , 'color' : 'Red' } ,
'banana' : { 'color' : 'red', 'prize' : 20, 'quantity' : 12 } };

for( var name in obj ) {
    alert( name + ': ' + obj[name].color );
}

You don’t need a library for this.

If you’re concerned that there may be additions to Object.prototype, then do this:

Example: http://jsfiddle.net/AkVvY/1/

for( var name in obj ) {
    if( obj.hasOwnProperty( name ) ) {
        alert( name + ': ' + obj[name].color );
    }
}
