Option trigger event for JavaScript

Author: User

First of all, it's easy to say jquery's option trigger event.

$ ("option:selected")//This will trigger the choice of option directly.


In JavaScript it's a bit of a hassle, in fact <option> doesn't trigger event methods, we only trigger in the OnChange method in select.

<select id= "pid" onchange= "Gradechange (this.value)" >   <option grade= "1" value= "a" > Option one </a>   <option grade= "2" value= "B" > option two </a></select>

JavaScript code

function Gradechange (value) {    alert (value)
