JavaScript/jQuery HTML Encoding

I am passing info down to the client as Json and I am generating some HTML from my javascript code. I have a field called name which I pass into the title of an image like this:

  html.push(<img  title=' + person.Name + ' src . . .

the issue is if the person.Name is Joe O'Mally' as it only shows up as Joe O when i hover over the image (because of the ' in the name)

I don't want to strip the ' on the serverside as there are other places where I want to show the exact string on the page.

Is there an Equivalent of HttpUtility.HtmlEncode in javascript that will show the full name in the image title, when I hover of the image?

No but you can write one pretty easily.

function htmlEnc(s) {

  return s.replace(/&/g, '&amp;')

    .replace(/</g, '&lt;')

    .replace(/>/g, '&gt;')

    .replace(/'/g, '&#39;')

    .replace(//g, '&#34;');

}

I've played with ways of making that faster (basically to do things with one replace call) but this performs well enough for most purposes, especially in modern browsers.
