根据json对象的某一属性对其进行排序

compare(property) {
            return function(a, b) {
                var value1 = a[property];
                var value2 = b[property];
                return value1 - value2;
            }
        },

<script>
	var json1 = [
				  {"name":"小明","avg":"80"},
				  {"name":"小红","avg":"70"},
				  {"name":"小绿","avg":"90"}	
				]
	console.log(json1);
</script>

var json2 = json1.sort(compare("avg"));
     console.log(json2)
