Create an array in javascript of custom objects

Question

Hi I need some help with javascript.

function PricingData(id,method,freq,service,price) {
            this.ID=id;
            this.PaymentMethod_ID=method;
            this.PaymentFrequency_ID=freq;
            this.Service_ID=service;
            this.Price=price;
        }

I need to create an array in this way.

var temp=new PricingData[]{new PricingData(1,2,3,4,5),new PricingData(1,2,3,4,5)};

but this doesn't work. I'm going to pass the data in through the server so I would prefer syntax similar to this

I am not sure what you mean by pass the data in through the server, but I'd suggest you may want to look at json. json.org You may also want to look at jquery for transferring your data between the server and browser jquery.Ajax() — Andrew

Use array literal notation to create an array:

var tmp = [new PricingData(1,2,3,4,5), new PricingData(1,2,3,4,5)];

For more information about arrays have a look at MDC - Array.

just out of curiosity, when an array is declared like this, how do you reference it?

Felix Kling Over a year ago

@david: tmp is a reference to the array. tmp[i] gives you the ith element. Is that what you wanted to know?

David Over a year ago

Ah - sort of, I meant as in can I do $var price= tmp[i].Price (to return the price), thank you

@David: Yes, you can do that (if you remove the $, it's not PHP ;))

That's how to create an array of custom object by using this syntax:

var myObjArr = new Array(new PricingData(1,2,3,4,5), new PricingData(1,2,3,4,5));

or

var myObjArr = [new PricingData(1,2,3,4,5), new PricingData(1,2,3,4,5)];
