Please, **1.** Say what you want to do exactly. **2.** Say what the problem is. **3.** Say what error appears. **4.** Say where the error appears. We cant do anyting, when you dont describe your problem! — Ba5t14n, Jan 30 '15 at 08:20
@Dyrandz Yes. Because it is business flow. But it is not necessary that backslash will come with every name. — Ishwar Lal, Jan 30 '15 at 08:45
`Uncaught SyntaxError: Unexpected token ILLEGAL` is this the error that you get? — Dyrandz Famador, Jan 31 '15 at 00:26

in Javascript you escape character with a backslash as well. When you want to write one in a string, use var str = "Ishwar Lal \\"

sorry, I dont understand what your problem is exactly, could you explain it a bit more detailed? – Ba5t14n Jan 30 '15 at 08:16
I have updated my question. Basically in my db there are number of names. Any name may contains "\". I can not hard code only for "Ishwar Lal \\" value. – Ishwar Lal Jan 30 '15 at 08:44

This javascript function will escape all special characters..

function addslashes(str) {
      return (str + '')
        .replace(/[\\"']/g, '\\$&')
        .replace(/\u0000/g, '\\0');
    }

I have used your mentioned method but not resolved. This message is coming "Unterminated string Constant" in JS error. @Dyrandz – Ishwar Lal Jan 30 '15 at 09:20
