我的编码有什么问题？

Question

So on a site they have a "level" where I need to take a lot of words put them in alphabetical order and then paste it in the answer box and then hit submit and all doing this in five seconds? I am using the console to execute the code which is as follows:

var id = document.getElementsByTagName("textarea")[0].innerHTML;
id = id.sort();    
id = id.join(",");
document.getElementsByName("answer")[0].innerHTML = id;

can someone tell me why it doesnt work though? I get the

/* Exception: TypeError: id.sort is not a function @Scratchpad/1:11:6 */

Can anyone tell me whats wrong? Thanks in advance!

Answer 1

It is because id is a string, not an array. You probably want to have a line like:

id = id.split(" ") //whatever the separator is

above the id.sort() line.
