How to encode ' character in Javascript?

Question

I have:

function showMessage(message) {
    alert(message);
}

But when the message comes dynamically from the server as(example): "Men's" it doesn't work.

I've tried:

function myEncode(message) {
    return message.replace("'", "\'");
}

showMessage(myEncode(message));

Doesn't seem to work. This is a simple example, the actual code is more complicated, but essentially this is the issue.

You should specify the g parameter, for a global replace (not only the first match).

You should also escape the slash:

function myEncode(message) {
    return message.replace(/'/g, "\\'");
}
