DOM Mutation Events seemed like a great idea at the time - as web developers create a more dynamic web it seems natural that we would welcome the ability to listen for changes in the DOM and react to them. In practice however DOM Mutation Events were a major performance and stability issue and have been deprecated for over a year 这是因为MutationObserver是监听DOM树变化的接口,一开始的时候后div先加载,然后是js加载,此时DOM树没有发生变化,所有MutationObserver的回调函数没有执行,当我们动态的改变DOM树的结构时,MutationObserver监听到了变化,所以回调函数起了作用。这就是我们最后看到的结果

By design, any jQuery constructor or method that accepts an HTML string — jQuery(), .append(), .after(), etc. — can potentially execute code. This can occur by injection of script tags or use of HTML attributes that execute code (for example, <img onload=>). Do not use these methods to insert strings obtained from untrusted sources such as URL query parameters, cookies, or form inputs. Doing so can introduce cross-site-scripting (XSS) vulnerabilities.
