DOM Operations

Three aspects; DOM core Html-dom Css-dom

Note the point:

Remove three ways to remove nodes in an event remove detach empty

Remove does not explain

Detach does not remove the matched element from the jquery object to the data attached to the reserved bound event

<script type="Text/javascript">$ (function () {$ ("ul Li"). Click (function () {alert ($ ( This). HTML ())})//var $li = $ ("ul Li:eq (1)"). Remove (); No events                      var$li = $ ("ul Li:eq (1)"). Detach (); With Event $li. AppendTo ("ul"); })         </script>

Determine if there is a style

Hasclass () determines if a function has a class that returns true False

Is () determines whether there is a value of $ ("P"). Is (". Anthor")

DefaultValue form Element Initial value

This.defaultvalue The current text box default value

Drop-down box selection mode

Val () $ (": CheckBox"). Val (["Check2"]);

attr () $ (). attr ("selected", true);

To traverse a node:

Children () Gets a collection of matched sub-elements that only considers the child element regardless of its descendant elements

Parent () parents () closet () difference

Wait for updates .....
