In this article, we will see how to globally replace a forward slash in a JavaScript string. We have a few methods to do this which are described below:
Methods to globally replace forward slash:
- Using replace() method with a regular expression
- Using JavaScript split() method
- Using JavaScript replaceAll() method
Method 1: Using replace() method with a regular expression.
The replace() method is used to replace the given pattern with another string. The pattern string can be a string or a regular expression. This function will return a new string with the replaced string. A regular expression is used to replace all the forward slashes. As the forward-slash (/) is a special character in regular expressions, it has to be escaped with a backward slash (\). Also, to replace all the forward slashes on the string, the global modifier (g) is used. It will replace all the forward slashes in the given string.Â
Syntax:
originalString.replace(/\//g, replacementString);
Example: This example shows the above-explained approach.
Javascript
// Input string let origString = 'string / with some // slashes /'; Â Â // Disply console.log(origString); Â Â // Replacement for slash let replacementString = '*'; Â Â // Replaced string let replacedString = origString.replace(/\//g, replacementString); Â Â // Display output console.log(replacedString); |
string / with some // slashes / string * with some ** slashes *
Method 2: Using the JavaScript split() method
The split() method is used to separate a string into an array of strings based on the separator. The string is first separated on the basis of the forward slash as the separator. It will give an array of strings separated at the point where the forward slash was present. The join() method is used to concatenate an array of strings with a specified separator. The required character to be used instead of the forward character is passed as a parameter here. This will replace all the forward slashes in the given string.Â
Syntax:
origString.split('/').join(replacementString)
Example: This example shows the above-explained approach.
Javascript
// Input String with slashes let origString = 'string / with some // slashes /'; Â Â // Display input string console.log(origString); Â Â // Replacement for slash let replacementString = '*'; Â Â // Replaced String let replacedString = Â Â Â Â Â Â Â Â Â Â Â Â origString.split('/').join(replacementString); Â Â Â Â Â Â Â Â Â Â Â Â Â Â // Display output console.log(replacedString); |
the
string / with some // slashes / string * with some ** slashes *
Method 3: Using JavaScript replaceAll() method
The Javascript replaceAll() method returns a new string after replacing all the matches of a string with a specified string or a regular expression. The original string is left unchanged after this operation.
Syntax:
const newString = originalString.replaceAll(regexp | substr , newSubstr | function)
Example :
Javascript
// Input string let origString = 'string / with some // slashes /'; // Display input string console.log(origString); Â Â // replacement cahracter let replacementString = '*'; Â Â // Replace all slash using replaceAll method; let replacedString = Â Â Â Â Â Â Â Â Â Â Â Â origString.replaceAll('/', '*'); Â Â // Display output console.log(replacedString); |
string / with some // slashes / string * with some ** slashes *
