//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 if (a > b) return reverse * 1;
return 0;
}
}
nodes.sort(SortBy('orderNum', false, parseInt));
把过个字段合并成单个 然后 排序字符串
nodes.sort(function (a, b) { return a.sort.localeCompare(b.sort) });
