How to replace " with \" in javascript

Question

I have a textbox that posts info to the server and it's in JSON format. Lets say I want to enter two quotes for the value, and the JSON struct would look like:

{
    "test": """"
}

I need it to look like:

{
    "test": "\"\""
}

so it will follow JSON standards and can be parsable/stringifyable.

I tried using

 var val = myVal.replace('"', "\\\"");

but this didn't work. val ends up with only one escaped quote like so \""Any help is much appreciated!

Answer 1

Use this

var val = myVal.replace(/"/g, '\\"');
