Several ways to add nodes

$ ("P"). Prepend ("<b> How are you? </b>);//forward "B" to P

$ ("P"). Before ("<b> How are you? </b>);//Add "B" before the P element
$ ("<b> how are you? </b> "). InsertBefore (" P ");//insert" B "in front of P element
Several ways to delete nodes
var $li =$ ("ul li:eq (1)"). Remove ();//delete the 2nd element node in the UL node
$ ("ul"). Append ($li);//Add the newly deleted element node to the UL element
$ ("ul Li"). Remove ("li[title!= pineapple");//Remove the LI element under the title attribute of the UL element not equal to "pineapple"
$ ("ul Li:eq (1)"). empty ();//Empty the contents of the 2nd Li element under the UL node
Replication nodes
/* $ ("ul Li"). Click (function () {
$ (this). Clone (True). AppendTo ("ul");//Copy the currently clicked node and append it to the "ul" element, copying its event when adding a parameter
});
*/

$ ("P"). ReplaceWith ("<strong> Your least favorite fruit? </Strong> ");
$ ("[name= ' RP ']"). ReplaceWith ("<tr><td>gg</td><td>gg</td><td>gg</td> <td>gg</td></tr><tr><td>gg</td><td>gg</td><td>gg</td ><td>gg</td></tr> ");
});
