How do conversions between DOM objects and Jquer objects convert a jquery object to a DOM object? Test is a span element var arr = $ ("P"); Get a jquery object to see the related properties alert (arr.length); 16 Elements Alert (arr[0].tostring ());//span object 1. Convert jquery to a DOM object var ardom = arr[0]; alert (ardom.innerhtml); Test//Since it is an array why not execute it? Because Jquer cashes cannot use the DOM object's method if (Arr.constructor = = Array) {alert ("yes");//Do not execute arr is a jquery object, so the DOM method does not work} 2. Converts a DOM object to a jquery object var d = document.getElementById ("Domobj"); var cr = $ (d); alert (cr.html ()); Methods for invoking jquery objects
