Converting between JavaScript and jquery __javascript

Dom object: A DOM element object obtained by the traditional JS method; jquery object: A new object generated after wrapping the original DOM object through the jquery method.

<script type= "Text/javascript" >
        $ (function () {
            //***** Dom object converted to jquery object *****//
            //dom object
            var ObjDom0 = document.getElementById ("Div0");
            Convert to jquery object
            var $obj 0 = $ (objDom0);
            Call the method in jquery to set the content
            $obj 0.html ("content set after the DOM object is converted to a jquery object");

            The jquery object is turned into a DOM object *****//
            //jquery object
            var $obj 1 = $ ("#div1");
            Convert to Dom object
            var objDom1 =  $obj 1[0];//or $obj1.get (0);
            Call object method in JavaScript set content
            objdom1.innerhtml = "content to be set after the JQuery object has been converted to a DOM object";
        }
    </script >
