根据age排序显示：
var arr = [{name: "zlw", age: 24}, {name: "wlz", age: 25},{name: "wlz", age: 28},{name: "wlz", age: 23}];
var compare = function (prop) {
return function (obj1, obj2) {
var val1 = obj1[prop];
var val2 = obj2[prop];if (val1 < val2) {
return -1;
} else if (val1 > val2) {
return 1;
} else {
return 0;
}
}
}
alert(JSON.stringify(arr));
console.log(arr.sort(compare('age')));
alert(JSON.stringify(arr));</script>
