javascript - 如何通过单击特定段落来激活事件

Question

我有这个功能:

$(document).ready(function(){

 $("p").click(function(){
     alert("The paragraph was clicked.");
 });
});

它有效，但我想将它限制在特定的段落中，例如:

<p class="titleM" id="tituloExist">ENTER WITH A NEW ACCOUNT</p>

Answer 1

你可以通过id或者class来选择你想要的

// by Class
$("p.titleM").click(function(){
   alert("By Class");
});

// by ID
$("p#tituloExist").click(function(){
   alert("By ID");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="titleM" id="tituloExist">ENTER WITH A NEW ACCOUNT</p>
