Juqery five documents process packages, replace, delete, and copy

Wrap (html)
Enclose all matched elements with the structured tags of other elements.
This packaging is most useful for inserting additional structured tags into a document and does not compromise the semantic quality of the original document.
The principle of this function is to check the first provided element (it is dynamically generated by the provided HTML Tag Code ), in the code structure, find the ancestor element at the top-this ancestor element is the wrapped element.

This function cannot be used when an element in the HTML Tag Code contains text. Therefore, if you want to add text, you should add it after the package is complete.

--------------------------------------------------------------------------------

Wrap all matched elements with a structure of other elements.
This wrapping process is most useful for injecting additional structure into a document, without ruining the original semantic qualities of a document.
This works by going through the first element provided (which is generated, on the fly, from the provided HTML) and finds the deepest ancestor element within its structure -- it is that element that will enwrap everything else.

This does not work with elements that contain text. Any necessary text must be added after the wrapping is done.
Return Value
JQuery

Parameters
Html (String): HTML Tag code String, used to dynamically generate elements and wrap target elements

Example
Wrap all the paragraphs with a newly created div

HTML code:

<P> Test Paragraph. </p>
JQuery code:

$ ("P"). wrap ("<div class = 'wrapp'> </div> ");
Result:

<Div class = "wrap"> <p> Test Paragraph. </p> </div>
Certificate -------------------------------------------------------------------------------------------------------------------------------------------------
Wrap (elem)
Wrap all matching elements with the structured tags of other elements.

--------------------------------------------------------------------------------

Wrap all matched elements with a structure of other elements.
Return Value
JQuery

Parameters
Elem (Element): DOM Element used to wrap the target Element

Example
Wrap each section with a div whose ID is "content"

HTML code:

<P> Test Paragraph. </p> <div id = "content"> </div>
JQuery code:

$ ("P"). wrap (document. getElementById ('content '));
Result:

<Div id = "content"> <p> Test Paragraph. </p> </div> <div id = "content"> </div>
Certificate -------------------------------------------------------------------------------------------------------------------------------------------------
WrapAll (html)
Wrap all matching elements with a single element
This is different from '. wrap ()', and '. wrap ()' is wrapped once for each matching element.
This packaging is most useful for inserting additional structured tags into a document and does not compromise the semantic quality of the original document.

The principle of this function is to check the first provided element and find the top ancestor element in its code structure-this ancestor element is the packaging element.

--------------------------------------------------------------------------------

Wrap all the elements in the matched set into a single wrapper element.
This is different from '. wrap ()' where each element in the matched set wocould get wrapped with an element.
This wrapping process is most useful for injecting additional structure into a document, without ruining the original semantic qualities of a document.

This works by going through the first element provided (which is generated, on the fly, from the provided HTML) and finds the deepest ancestor element within its structure -- it is that element that will enwrap everything else.
Return Value
JQuery

Parameters
Html (String): TML marks the code String, which is used to dynamically generate elements and package target elements.

Example
Wrap all paragraphs with a generated div

HTML code:

<P> Hello </p> <p> cruel </p> <p> World </p>
JQuery code:

$ ("P"). wrapAll ("<div> </div> ");
Result:

<Div> <p> Hello </p> <p> cruel </p> <p> World </p> </div>
Certificate -------------------------------------------------------------------------------------------------------------------------------------------------
WrapAll (elem)
Wrap all matching elements with a single element
This is different from '. wrap ()', and '. wrap ()' is wrapped once for each matching element.

--------------------------------------------------------------------------------

Wrap all the elements in the matched set into a single wrapper element.
This is different from '. wrap ()' where each element in the matched set wocould get wrapped with an element.
Return Value
JQuery

Parameters

Example
Wrap all paragraphs with a generated div

HTML code:

<Div> <p> Hello </p> <p> cruel </p> <p> World </p> </div>
Certificate -------------------------------------------------------------------------------------------------------------------------------------------------
WrapInner (html)
Wrap the child content (including text nodes) of each matching element in an HTML structure.
The principle of this function is to check the first provided element (it is dynamically generated by the provided HTML Tag Code ), in the code structure, find the ancestor element at the top-this ancestor element is the packaging element.

--------------------------------------------------------------------------------

Wrap the inner child contents of each matched element (including text nodes) with an HTML structure.
This wrapping process is most useful for injecting additional structure into a document, without ruining the original semantic qualities of a document. this works by going through the first element provided (which is generated, on the fly, from the provided HTML) and finds the deepest ancestor element within its structure -- it is that element that will enwrap everything else.
Return Value
