如果要包括文本节点，则需要使用contents()并弄清相对于其父级的.son索引:>

If you want to include text nodes, you will need to use contents() and figure out the index of .son in relation to its parent:

var $contents = $(".mother").contents();
var sonIdx = $contents.index($(".son"));
var elements = $contents.filter(function(i) {
    return i > sonIdx;
}).get();

这是一个小提琴，它可以演示.
