1. Search nodes ① you can search Nodes Based on the jquery selector ② available. text () to get the text content of the node ③ available. attr ("attr") obtains the attribute value2 to create a node. ① The jquery factory function can be used to complete $ (html) eg: $ ("<li> </li> ") you can add text and properties for the label at the same time. 3. Insert node ① method (see the document). ② The method can not only insert nodes, you can also move a node. 4. delete a node. ① remove () remove all matching elements. ② detach () remove all matching elements, unlike remove, the removed content retains sample data. All bound events and additional data are retained. ③ empty () clears nodes, clear all child nodes of matching elements, including content 5 Copy nodes ① clone (true) Copy matched nodes; if the input parameter is true, the binding event 6 of the element is copied to replace node ① replaceWith () eg:. replaceWith (B) B replace A ② replaceAll () and replaceWith () replace and replaced node opposite 7 Package node ① package node. wrap ("<B> </B>") uses the <B> label to wrap A. If A is A multi-node object, A <B> label Package A for each node. wrapAll ("<B> </B>") if A is A multi-node object, A label is provided for the object, and all nodes are wrapped in A. B label. wrapInner ("<B> </B>") provides A <B> label 8 attribute operation ① To obtain and set attribute A for each node that matches the tag object. attr ("title");. attr ("title", "value") ② Delete attribute. removeAttr ("title"); 9. style operations ① get and set styles (operate class attributes) E. attr ("class"); E. attr ("class", "value"); ② append style addClass ("className") append a className ③ remove style removeClass ("className") Remove a className ④ switch style. toggleClass ("className") removes the class if the style exists.

If multiple elements are selected, an array 11 matching node is returned for search ①. children () searches for all child nodes that match nodes. (Only child nodes are considered, and other child nodes are not considered.) ②. next ()/. prev ()/siblings () searches for peer elements matching nodes (Back/Front/All); ③. parent ()/. parents () Find the parent element of the matching node 12 css-dom operation ① get/set the style value $ ("E" ).css ("cssAttr ") $ ("E" ).css ("cssAttr", "value"); ②. offset ()/. position () is used to obtain the left/top value offset or set the position value relative to the window value to obtain or set the value relative to the first absolute or relative positioning ancestor element ③. scrollTop ()/. scrollLeft () gets or sets the distance between the scroll bar and the top or left side.
