JavaScript元素点击事件的相关内容

请在js如何为元素添加特定的点击事件？

是这个意思，jq里面不是可以$('.a').on('click.abc', function(){})这样吗我想知道，js怎么添加类似abc的效果？document.querySelector('.a').addEventListener('click', function(){})这样不能加abc，请问怎么实现呢？

通过js添加的元素点击事件无法触发

js添加div的语句： var blk_have =" ";$("#blk").prepend(blk_have);$(".sw-off").click(function(){ $(this).toggleClass("sw-on"); });只截取了部分代码但是手动在页面上这样写却可以触发click事件..... 想问问这样为什么不会更改class？
