Collection Functions (Arrays or Objects) _.each(list, iterator, [context]) Alias: forEach Iterates over a list of elements, yielding each in turn to an iterator function. The iterator is bound to the _.map(list, iterator, [context]) Alias: collect P
代码如下: //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; return 0; }
