Question

I tried many different methods but can’t seem to work this one out.
I have a JSon array which populates my JQuery list. The list displays correctly, but I cant seem to be able to filter it.

I’d like to be able to filter by name or price. I tried the JQuery .Filter method and many others, and they all failed. I’d also like to make it as a link. ( The user clicks sort by name, and it sorts… )

Heres what I have so far, which I was convinced would work.

Any help is greatly appreciated, Thanks !

.js file :

// Json array
var productList = {"products": [
    {"description": "Product 1", "price": "3.25"},
    {"description": "Product 4", "price": "9.97"},
    {"description": "Product 3", "price": "4.21"},
    {"description": "Product 2", "price": "5.24"},
    {"description": "Product 5", "price": "8.52"}
]
};

function loadList() {

var list = $("#productList").listview();

// load array into list
$(productList.products).each(function(index) {
    $(list).append('<li id="listitem">' + this.description + "  " +
            "    :     " + this.price + '</li>');

     // sort by price 
     $(productList.products).filter(function ()
     { return parseFloat(this.price) < 11;})

});
    $(list).listview("refresh");
}

How about this for sorting:

var prods = productList.products.sort(function(a, b) {return parseInt(a.price) < parseInt(b.price);});
$.each(prods, function() {
    list.append("<li>" + this.description + " : " + this.price + "</li>");
});

To sort by description, you could use this instead:

var prods = productList.products.sort(function(a, b) {return a.description < b.description;});

If you just want to filter, you could substitute:

var prods = productList.products.filter(function(item) {return parseInt(item.price) < 5;});
