Answer 1

In RegEx, the caret symbol is a recognized as a special character. It means the beginning of a string.

Additionally, replace returns the new value, it does not perform the operation in place, youneed to create a new variable.

For your case, you have to do one of the following:

var temp =  "^hall^,^restaurant^";
var newString = temp.replace(/\^/g, ''); // Escape the caret

Or simply replace the character without using RegEx at all:

var temp =  "^hall^,^restaurant^";
while (temp.indexOf('^') >= 0) {
    temp = temp.replace('^', '');
}

Alternative version:

var temp =  "^hall^,^restaurant^";
var newString = temp.split('^').join('');
