$ (' #id '). Siblings ()   the current element for all sibling nodes $ (' #id '). Prev () The       current element before a sibling node $ (' #id '). Prevaall ()   the current element precedes all sibling nodes $ (' #id '). Next () The       current element after the first sibling node $ (' #id '). Nextall ()    all sibling nodes after the current element

  $ (' #id '). Parent (expr)//Find parent Element
  $ (' #id '). Parents (expr)//finds all ancestor elements, not limited to parent elements
  $ (' #id '). Children (expr)//Find all child elements and will only find the immediate child node and will not return all descendants
  $ (' #id '). Contents ()//Find everything below, including nodes and text.
  $ (' #id '). Prev ()//Find the previous sibling node, not all sibling nodes
  $ (' #id '). Prevall ()//Find all previous sibling nodes
  $ (' #id '). Next ()//Find the next sibling node, not all sibling nodes
  $ (' #id '). Nextall ()//Find all subsequent sibling nodes
  $ (' #id '). Siblings ()//Find sibling nodes, no front and back
  $ (' #id '). Find (expr)//Unlike jquery.filter (expr), jquery.filter (expr) is a partial filter from the initial collection of
  JQuery objects. The return result of Jquery.find () will not have the initial set
        filter out part, and Jquery.find () will not have the contents of the initial collection, such as:
  $ (" P "). FIND (" span ") is found starting from the element, equal to $ (" p span ")

// The picker gets the element under which an element traverses $ ("#queryTableDilog table"). each (function () {}); // finds all specified elements under an element collection of $ ( This

// The radio box gets the selected item $ ("Input[name= ' 1isopen ']:checked"). Val ();

// Ajax $.ajax ({            ' POST ',            "login.htm",            data: {                dbName: $ ("#"). Val ()            } ,            DataType:"JSON",            success:function (data) {            },            error:function (Request, Textstatus) {            }});
