$("#experiences tr")
For the above one,how to judge if it's empty or not?
I thought its boolean value should be false,but seems not.

The is() method is used to check if one of the selected elements matches to the selector element. This method can be used on this element to test if it is empty by using “:empty” selector. The “:empty” selector is used to select all the elements that have no children.
The empty() method removes all child nodes and content from the selected elements. Note: This method does not remove the element itself, or its attributes. Tip: To remove the elements without removing data and events, use the detach() method. Tip: To remove the elements and its data and events, use the remove() method.
Use the childNodes property to check if a div element is empty. The childNodes property returns a NodeList of the element's child nodes, including elements, text nodes and comments. If the property returns a value of 0 , then the div is empty.
use the length property:
$("#experiences tr").length if it's 0 it's empty
