JSON 数字排序多字段排序介绍

//排序数组 
function SortBy(field, reverse, primer) { 
reverse = (reverse) ? -1 : 1; 
return function (a, b) { 
a = a[field]; 
b = b[field]; 
if (typeof (primer) != 'undefined') { 
a = primer(a); 
b = primer(b); 
} 
if (a < b) return reverse * -1; 
if (a > b) return reverse * 1; 
return 0; 
} 
} 
nodes.sort(SortBy('orderNum', false, parseInt));

nodes.sort(function (a, b) { return a.sort.localeCompare(b.sort) });
