How do i compare an as3 string with a json array? - arrays

Question

Im trying to compare two specific bits of information. One is in the form of a as3 string the other is in the form of a Json array.
The Json array shows customer data from a shop website. What i want to do is have as3 compare the string(i.e a customer name) with the data , and when it has found the matching name, only trace that customers specific information.
Im amusing id have to use a loop for the comparison , but im having trouble getting my head around how to convert the Json into specific junks that can then be compared individually with a string. Any help would be perfect.
Thanks

Answer 1

Be aware that JSON is just a standard AS3 object. There's no magic going on here; loop through it as you would any other structure and run your comparisons as usual.
Solution
var jsonObj:Object = {
"customers": [
{
"id": "04aa1ab3-521b-11e3-a29a-bc305bf5da20",
"name": "fake name",
"customer_code": "00000002",
"customer_group_id": "6012cd22-5166-11e3-a29a-bc305bf5da20",
"customer_group_name": "All Customers",
"first_name": "test",
"last_name": "test",
"company_name": "",
"email": "testest#yahoo.com"
}
]
}
var myString:String = "fake name";
for (var k:String in jsonObj.customers[0]) {
var v:String = jsonObj.customers[0][k];
if (v == myString) {
trace(myString + "'s email is " + jsonObj.customers[0].email)
}
}

Answer 2

Use a Dictionary Object to store customer objects using their unique names (or ids ) as reference;
You certainly do not want to write unnecessary loop search for a customer in question.
Solution.
var jsonObj:Object = {
"customers": [
{
"id": "04aa1ab3-521b-11e3-a29a-bc305bf5da20",
"name": "fake name",
"customer_code": "00000002",
"customer_group_id": "6012cd22-5166-11e3-a29a-bc305bf5da20",
"customer_group_name": "All Customers",
"first_name": "test",
"last_name": "test",
"company_name": "",
"email": "testest#yahoo.com"
}
]
}
//Dictionary Object to store customers
var customers:Dictionary=new Dictionary();
//customer object in the json
var customer:Object;
//loop json object to retrieve customers and
//store them in Dictionary using either unique name or id
for each(customer in jsonObj)
customers[customer.name]=customer;
//retrieve customer in question
function getCustomer(id:String):Object
{
return customers[id] as Object;
}
