JavaScript - How to escape quotes in var to pass data through Json

I pass some data through Json to Webservice. My problem is that I am passing html (from tinyMCE input), so var has content using quotes and that gives me problems. I pass the values ​​as follows:

 data: '{ id: "' + news_id + '", title: "' + news_title + '", body: "' + news_body + '" }',

Are there any espace quotes in javascript so i can send html to this news_body var?

thank

if you are familiar with PHP, you can use some functional form based on PHP

phpjs.org

They created a javascript function that works like functions in a PHP library. You can use the addlashes function here.
