javascript - 如何从列表中删除@yahoo.com 并对其进行排序？

Question

<p id="demo"></p>

<script>

//This is the email list
var emailList =["adam@yahoo.edu\n", "henry@yahoo.edu\n", "john@yahoo.edu\n", "sally@yahoo.edu\n", "adam@yahoo.edu\n", "david@yahoo.edu\n", "myhome@yahoo.edu\n", "david@yahoo.edu\n", "david@yahoo.edu\n", "hunger@yahoo.edu\n", "madison@yahoo.edu\n", ];

document.getElementById("demo").innerHTML = emailList;

//I want to remove the @yahoo.com and then sort the list
function myFunction() {
   var myEmailList = emailList.replace("@yahoo.com", " ");
   myEmailList.sort();
   document.getElementById("demo").innerHTML = myEmailList;
}

</script>

</body>

Answer 1

一句俏皮话，人们喜欢俏皮话

var names = emailList.map(function(e){ return e.split('@').shift(); }).sort();

如果您想专门取出@yahoo*，请将分割参数更改为“@yahoo”

 var names = emailList.map(function(e){ return e.split('@yahoo').shift(); }).sort();

这将使非雅虎地址保持不变。
