js运用sort对json 数组进行排序

var p = [5, 2, 3, 1, 7, 5, 6, 9, 6, 0];
function down(a, b) {
return   (a < b) ? 1 : -1
}
p.sort(down)
alert(p)
json排序

var p = [
{name:"kitty", age:12},
{name:"sonny", age:9},
{name:"jake", age:13},
{name:"fun", age:24}
]
function down(x, y) {
return (x.age < y.age) ? 1 : -1

}
p.sort(down)
var $text = "<div>"
$.each(p, function (key, value) {
var $div = "<div>"
$.each(value, function (key, value) {
$div += "<span>" + key + ":</span>" + "<span>" + value + "</span>" + "         "
})
$div += "</div>"
$text = $text + $div
})
$text += "</div>"

$(".text").html($text)

<script type="text/javascript">
