wrap() method description

wrap() method usage Wrap each selected element with the specified HTML element, that is, add a parent element outside the selected element.

This kind of wrapping is most useful for inserting additional structured markup into the document without destroying the semantic quality of the original document. The principle of this function is to examine the first element provided (which is dynamically generated from the provided HTML markup code) and find the top-level ancestor element in its code structure - this ancestor element is the wrapping element. This function cannot be used when the element in the HTML markup code contains text. Therefore, if you want to add text, you should add it after the package is completed.

Grammar:

$(selector).wrap(html|ele|fn)
