regex replace in javascript/jquery

Question

I've never really used regex so this is probably a basic question, but I need to reformat a string in javascript/jquery and I think regex is the direction to go.

How can I convert this string:

\"1\",\"2\",\"\\",\"\4\"

into:

"1","2","","4"

These are both strings, so really they'd be contained in "" but I thought that may confuse things even more.

I've tried the following but it doesn't work:

var value = '\"1\",\"2\",\"\\",\"\4\"'.replace(/\"/, '"').replace(/"\//, '"');

why are you not replacing only \ ..does it need to be before " only — Anirudha

Try:

var value = your_string.replace(/\\/g, "");

to remove all the "\"

thanks, this doesn't appear to do anything, in chrome's console i entered: $('.inputParameters').val().replace(/\//g, ""); which returned "\"1\",\"2\",\"3\",\"\\"" where $('.inputParameters').val() contains the original value

1. $("inputParameters").val() will not be changed, until you change it with val(newvalue) 2. Seems like "\"1\",\"2\",\"3\",\"\\"" has an extra slash or an unescaped quote at the end

thanks for the help, i have it now, needed to be /\\/g instead of /\//g

It's a lot of escaping... Your string is:

var str = '\\"1\\",\\"2\\",\\"\\\\",\\"\\4\\"'

console.log(str.replace(/\\/g, '')) // "1","2","","4"

However, if you want only to replace \" with " use:

console.log(str.replace(/\\"/g, '"')) // "1","2","\","\4"
