Replace a backslash comma to double backslash comma

Question

How do I change replace a "\\," to "\\\\," ? So that, the string OU=b\\,aditi,DC=zeus2,DC=com becomes OU=b\\\\,aditi,DC=zeus2,DC=com ??

I need some javascript solution, regex or replace function will do.

Answer 1

You can use the following:

str = str.replace(/\\,/g, "\\\\,");

See DEMO

 var str = 'OU=b\\\\,aditi,DC=zeus2,DC=com'; alert("before: "+str); str = str.replace(/\\\\,/g, '\\\\\\\\,'); alert("after: "+str);

var result = str.replace(re, subst);

 var re = /\\\\/; var str = 'OU=b\\\\,aditi,DC=zeus2,DC=com'; var subst = '\\\\\\\\'; var result = str.replace(re, subst); document.getElementById("results").innerHTML = result
