JQuery. parseHTML () function details

This article mainly introduces the jQuery. parseHTML () function, which is used to parse HTML strings into corresponding DOM node arrays. For more information, see definitions and usage.

$. ParseHTML () is used to parse an HTML string into a corresponding DOM node array.

Note:

1. This function will use the native DOM element creation function to convert the HTML string into a collection of DOM elements. you can insert these DOM elements into the document.

2. If the context parameter is not specified, or the parameter is null or undefined, the current document is used by default. If the created DOM element is used in another document, for example, iframe, you should specify the document Object of the iframe.

Security considerations: Most jQuery APIs allow HTML strings to include running scripts in HTML. JQuery. parseHTML () does not run scripts in the parsed HTML, unless you explicitly set the keepScripts parameter to true. However, most environments can still execute scripts indirectly, for example, through attributes. The caller should avoid this and clear or escape any untrusted input from sources such as URLs and cookies to prevent this situation. For future compatibility considerations, when the keepScripts parameter is omitted or false, the caller should not rely on any running script content.
