Javascript: Using eval() with a string containing double quotes and single quotes

Hello all.

I am trying to "push" values into an array after they've been used in an eval() statement. The issue I'm running into is that with the way I'm concatenating the string, the double quotes inside the "text being evalled" is causing the eval() function to choke.

Here is an example.

Description fields is equal to -------->        This is a test, "yes", a test

eval("obj." + "description" + " = '" + $('#description').val() + "'");      

With this as an example, the " in "yes" messes things up. I've tried using " but the & then messes it up. I've also tried replacing the " with \".

Any suggestions on how to "escape" the double quote?

have you tried replacing " with \\\" OR \\\\\"

That is escaping the the escaping character

instead of
eval("obj." + "description" + " = '" + $('#description').val() + "'");
have u tried like below
eval("obj." + "description" + " = '" + $('#description').val().replace('"','\"') + "'");

replacing " with \" generates this JS error in firebug.

Error: missing ; before statement

Line: 38, Column: 22
Source Code:
obj.description = '9' 6" 2PC 3LBL testing 3'

Well, looking at the message closely, why would this be tied to jQuery?

var xx = htmlEncode($('#description').val());
eval("obj." + "description" + " = '" + xx + "'");

function htmlEncode(value){
  return value.replace(/"/g,'\"');

Might it be the single quote messing it up?
WebspeederAuthor Commented:
I've tried escaping both with \' and \"
can you paste that portion of the code if you don't mind.

Just use
obj["description"] = $("#description").val();
