Return hello world to olleh dlrow in javascript

Question

Was wondering if you can reverse a string and still maintain the order.

Below is a function that returns "dlroW olleH" and I want to return "olleH dlroW"

var myFunction = function() {
var userdata = document.getElementById('data').value,
    uRev = userdata.split("").reverse().join("");
document.getElementById('results').innerHTML = uRev;
};

Thanks!

@JamesDonnelly That question is about reversing the whole string, not one word at a time. See the duplicate I found. — Barmar, Oct 28 '13 at 15:48

Reverse the words and then the characters:

var myFunction = function() {
    var userdata = document.getElementById('data').value,
    uRev = userdata.split(" ").reverse().join(" ").split("").reverse().join("");
    document.getElementById('results').innerHTML = uRev;
};

function reverseString(s){
    return s.split("").reverse().join("");
}

function reverseEachWord(s) {
    return s.split(" ").map(reverseString).join(" ");

Didn't see your answer :) lost between all the others. The other answers reverse the order of the words, then the string (Hello World -> World Hello -> olleH dlroW). This version reverses each individual word. It might be better suited. – Tibos Oct 28 '13 at 15:52

first split your string in an array of words using split(" "), then split each array segment using the method above.

Try this,

var myFunction = function() {
    var resArr=[];
    var userdata = document.getElementById('data').value,
    uRev = userdata.split("");
    for (var i=0;i<uRev.length;i++){
      resArr.push(uRev[i].reverse());
    }

    document.getElementById('results').innerHTML = resArr.join('');
};

        /\w+/g , 
        function(a){return a.split('').reverse().join('');}
    )
);
