How to Parse an JS Array?

I have the following information:

1. The city name, in this case Littelside. This is stored in a variable var city

2. I have an array of {} objects. Each contains address, city, name, state and zip-code

[{"address":"07288 Albertha Station",**"city":"Littelside"**,"created_at":"2011-05-25T19:24:51Z","id":1,"name":"Mr. Emmitt Emmerich","state"开发者_开发问答:"Missouri","updated_at":"2011-05-25T19:24:51Z","zip":"75475-9938"},{NEXT OBJECT WITH ADDRESS CITY ETC}]

How do you use the var city as a search term to parse the array, and return address, city, state, name and zip of the array with the matching city?

Thanks!

The function you're looking for is $.grep().

var city='Littelside';

var cucc=$.grep(your_array, function (a) {
    return a.city==search;
})[0];

$.grep will still return an array, with all the elements inside that satisify the filter function. Here I've use [0] to get the first result, which is fine in case you're sure that there will be one result. So cucc will have the whole object you're looking for.

var myarr  =  [{"address":"07288 Albertha Station","city":"Littelside","created_at":"2011-05-25T19:24:51Z","id":1,"name":"Mr. Emmitt Emmerich","state":"Missouri","updated_at":"2011-05-25T19:24:51Z","zip":"75475-9938"}];
var city = 'Littelside';
$.each(myarr,function(key,value){
    if(value['city']== city){
        alert('hello');
    }
})

here's a working demo

A function I use.

function arrayIndexOfProp(arr, prop, obj) {
        var i = arr.length;
        while (i--) {
            if (arr[i] && arr[i][prop] === obj) {
                return i;
            }
        }
        return -1;
    }

var index = arrayIndexOfProp(theArray, "city","Littelside");
// do stuff with theArray[index]

Array.prototype.reduce as in

Array.prototype.reduce(
    function (prev, current) {
      return prev || current.city === "Littelside" ? current : null;
    })

Loop over the array until you find one where the_array[i].city matches.
