警报返回值显示正确的字符串，而作为变量存储则返回未定义

Question

This returns the expected value:

alert($('#previous a').attr("href"));

This returns undefined :

var a = $('#previous a').attr("href");
alert(a)

I could not figure out why. Can someone help me :)

Answer 1

Your code is working fine.Try below.

 var a = $('#previous a').attr("href"); alert(a) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="previous"> <a href="www.google.com">Google</a> </div>
