JavaScript突出显示内联样式

Posted 2021-02-26

Puts a red border around anything with an inline style. Prefix with "javascript:" and paste into the address bar to run on a page directly, or run with a load event.

var elements = document.getElementsByTagName("*"); for (i = 0; i < elements.length; i++) { if (elements[i].getAttribute('style')) { var oldstyle =  elements[i].getAttribute('style'); elements[i].setAttribute('style', oldstyle + "border: 1px solid #f00;"); } }
