on('click',func) 和 $(document).on('click','.smt',func)?

自学小白想问一下两者的分别

$('.stm').on('click',function(){
});  
$(document).on('click','.stm',function(){
});

$(document).on('click','要选择的元素',function(){})
   on方法包含很多事件,点击,双击等等事件。和$().click()的用法一样,最大的区别即优点> 是如果动态创建的元素在该选择器选中范围内是能触发回调函数。
...动态添加的元素也能被点击触发函数
