Question

I have some JSON data which is in the following format:

[
    {
        "id": 145,
        "Name": "John",
        "company_name": "A",
        "email": "[e-mail]",
        "country": "USA"
    },
    {
        "id": 500,
        "Name": "Mike",
        "company_name": "B",
        "email": "[e-mail]",
        "country": "London"
    },
    {
        "id": 100,
        "Name": "Sally",
        "company_name": "C",
        "email": "[e-mail]",
        "country": "USA"
    }
]

Now, suppose I ask the user to enter an id, say 100. Then I need to display all the details for this id.

I am supposed to do this as a part of a web application,where I have to invoke an display the fields of a particular id. This would have been easy if I had a hash like implementation and could display all parameters based on the key-id.

Can anybody tell me how this can be done using such kind of data?

Thanks!

You could use something like this:
(Assuming the you have a variable data with your Json Object).

function getid(id) {
 var nobj;     
data.forEach(function(obj) {
if(obj.id == id)
    nobj = obj;
});
return nobj    
}
var neededobj = getid(100);
    console.log(neededobj.Name + "\n" + neededobj.email + "\netc...");

But to get the Object you have to loop through your complete array,
until it finds the right Object
