I have to check if a string contains some special character, and if it does, add a backslash to it.
var spChar=['%','^','!'];
If string is "This contains % and ^ characters".
I want to make it "This contains \% and \^ characters".
I dont want to loop through all the characters. Is there anyway i can achieve this by using regex
You can use a regex like
"This contains % and ^ characters".replace(/([%^!])/g, '\\$1')
But if you are looking to escape regex, you can use a function like
if (!RegExp.escape) {
RegExp.escape = function (s) {
return s.replace(/[\-\[\]{}()*+?.,\\\^$|#\s]/g, "\\$&")
};
}
//then
var newstring = RegExp.escape(mystring)
