Two different ways to get parent elements and delete child elements using js and jquery_javascript skills

var obj=document.getElementById("id"); What you get is the dom object. Use the js method when operating on the object

var obj=$("#id"); What you get is a jquery object. Use the jquery method when operating on this object

1. Traverse the objects obtained above

(1).js method for(vat i=0;j

(2).jquery method $(“#id”).each(function(){ $(this) to get the corresponding element});

2. Get the parent element of the element that meets the condition

(1).js method: var o=obj[i].parentNode

(2).jquery method: var o=$(this).parent()

2. After getting the parent element, you can delete the child elements of the parent element

(1).js method: o.removeChild(obj[i]);

(2).jquery method: o.empty()
