jquery Source Parsing----internal Insert external function

Take the Append () implementation of jquery as an example

append:function () {    returnthis. Dommanip (arguments, function (elem) {         if  This 1  This  One  This 9 ) {            varthis, elem); // will be implemented in the following             Target.appendchild (Elem);}}    );}

Implementation of Manipulationtarget ():

 function manipulationtarget (elem, content) { return  jquery.nodename (elem,  " table   ") && Jquery.nodename (content.nodetype !== 11 ? Content:content.firstChild,  " tr  "?  Elem.getelementsbytagname (  " tbody   ") [0 ] | | Elem.appendchild (elem.ownerDocument.createElement ( " tbody   "    

To see the manipulation () implementation above, note that the three-mesh operator is less than the priority of operator &&, so Manipulationtarget () returns the Elem or returns TBODY and its innerhtml;

The NodeName method of jquery has to be viewed on its own page.
