Essence of XSS InjectionThat is, an executable js Code is generated on a webpage based on user input, and the JavaScript code is executed by the browser. the string sent to the Browser contains an invalid js code, which is related to the user input.

There are countless discussions about how XSS is formed, how it is injected, how it can be done, and how to prevent it. Almost every article that talks about XSS will mention how to prevent it at the end. However, most of them remain unchanged. Escape, filter, or forget something.
