text - Escape all special characters in a string that is sent by jquery ajax

Question

I am trying to send text in key value pairs while doing a contentType: "application/json; charset=utf-8", ajax post to a web service. The problem I am facing is that if one of the parameters (that accepts text from the user) has quotes (") it breaks the code [Eror message: Invalid object passed in ] . So far I have tried these without any success

var text = $("#txtBody").val(); 
var output1 = JSON.stringify(text); 
var output2 = text.replace(/[-[]{}()*+?.,\^$|#s]/g, "\$&"); 

Any ideas on how to escape the special characters for the jquery ajax post?

Answer 1

Why not use escape?

escape(text);

EDIT!!!!

As mentioned in comments, this is deprecated.

The deprecated escape() method computes a new string in which certain characters have been replaced by a hexadecimal escape sequence. Use encodeURI or encodeURIComponent instead.

Instead use one of the following:
