Question

I have a multi-dimensional array in javascript defined as :-

myArray[0][0] = Some IMage;
myArray[0][1] = Some price;
myArray[0][2] = Some name;
myArray[0][3] = Some values;
myArray[0][4] = Some otherValues;
myArray[1][0] = Some IMage;
myArray[1][1] = Some price;
myArray[1][2] = Some name;
myArray[1][3] = Some values;
myArray[1][4] = Some otherValues;

Now my job is to sort them according to the price . How can this be done ?

Answer 1

Per my comment above, you should probably use objects instead of multi-dimensional arrays. Here’s an example (imagine your additional attributes like name and IMage included, which I didn’t include for the sake of less typing)

var arr = [
    { price: 12, something: 'a b c' },
    { price: 8, something: 'a b c' },
    { price: 45, something: 'a b c' },
    { price: 10, something: 'a b c' }
];

arr.sort(function(a, b) { return a.price - b.price; });

/*
    arr is now:

    [ 
        { price: 8, something: 'a b c' },
        { price: 10, something: 'a b c' },
        { price: 12, something: 'a b c' },
        { price: 45, something: 'a b c' } 
    ]
