Var obj = document. GetElementById (" id "); What you get is a dom object, which you manipulate using the js method
Var obj = $(" # id "); You get a jquery object, and you use jquery methods when you manipulate that object
1. Iterate over the objects obtained above
(1). Js method For (VAT I = 0; J< Obj. Length; I ++){obj[I] to get a corresponding element}
(2). The jquery method $(" #id ").each(function(){$(this) to get the corresponding element};
2. Gets the parent of the element that satisfies the condition
(1). Js method: var o=obj[I]. ParentNode
(2). Jquery method: var o=$(this).parent()
2. After obtaining the parent element, you can delete the child element of the parent element
(1). Js method: o.removeChild(obj[I]);
(2). Jquery method: o.epty ()
