2020-09-06 前端JS和jQuery事件

事件有三种形式：

onclick

onclick=function(){}

addEvent

除此之外jQuery还有变通形式：As of jQuery version 1.7, the on() method is the new replacement for the bind(), live() and delegate() methods. This method brings a lot of consistency to the API, and we recommend that you use this method, as it simplifies the jQuery code base.

$("p").click(function(){

  alert("The paragraph was clicked.");

});

$("p").on("click", function(){

  alert("The paragraph was clicked.");

});
