Getting information from a user-provided account list into an array in Javascript

Users will paste an account list in this format, with a username, a colon, and a password on each line.

    username1:password1
    username2:password2
    username3:password3
    username4:password4

What is the best way to 开发者_如何学JAVAseparate each line and then each part in Javascript? I'd really like it to be as simple as accounts[1].username or accounts[3].password to retrieve data. Thanks!

What you need is JSON. You need to parse that information and form the json objects array. Example from previous link

var myJSONObject = {"bindings": [
        {"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"},
        {"ircEvent": "PRIVMSG", "method": "deleteURI", "regex": "^delete.*"},
        {"ircEvent": "PRIVMSG", "method": "randomURI", "regex": "^random.*"}
    ]
};

myJSONObject.bindings[0].method    // "newURI"

I hope passwords are not allowed to have colons in them or they're encoded somehow prior to you having to split on a colon. :)

// for each account string, split it on a colon.
var accountString = 'username1:password1';
var accountInfo = accountString.split(':');

// initialize an accounts array.
var accounts = [];

// add a new item (in JSON format here) to the accounts array.
accounts.push({username : accountInfo[0], password : accountInfo[1] });

replace : with ,password: for each line

insert {username: at beginning of each line

insert }, at end of line

trim last comma ","

concat with {accounts:[ + modified string + ]}

this gives you a json string, eval it as json
