AppendTo ($('# wu')); $('Lu Xun'). PrependTo ($('# wu')) / / add existing nodes and change the location of $('# shu'). Prepend ($('# wu li:eq (1)'); / / 2. Addition of sibling. After. Before. InsertAfter. InsertAfter. InsertBefore / / active $('# liu'). After ('Zhao Yun'); $('# liu'). Before ('Zhuge Liang'); / / passive $(Huang Yueying). InsertAfter ($('# liu')) $(Sun Shangxiang). InsertBefore ($('# liu'))

Delete node .empty () .remove ()

$('# wu'). Empty (); / / clear the corresponding child node $('# fei') .remove (); / / delete the matching node
