Using JavaScript to Remove All Pipe Characters From String

In JavaScript, we can remove all pipe characters from a string easily by making use of the JavaScript String replace() method.

var someString = "|This is |a |string with pipe characters|";

someString = someString.replace(/\|/g, '');

console.log(someString);

#Output:
This is a string with pipe characters

Since pipe characters are special characters we must escape them by putting a backslash in front of them, as seen in the code above.

Notice in the replace method above, that instead of using .replace("\|", '') we use replace(/\|/g, ''). If we used the expression "\|" in the replace function, it only replace the FIRST instance of a pipe character. Using the regular expression /\|/g makes it so we replace ALL instances of a pipe character in the string.

When using string variables in JavaScript, we can easily perform string manipulation to change the value of the string variables.

One such manipulation is to remove characters from a string variable. Pipe characters can be troubling characters to deal with in string variables.

We can easily remove pipe characters from a string in JavaScript.

The easiest way to get rid of a pipe character in a string using JavaScript is with the JavaScript String replace() function.

The replace() function takes two arguments: the substring we want to replace, and the replacement substring. In this case, to remove pipe characters, we pass the pipe character (“\|”) character as the first argument and an empty string as the second argument.

Below is our example again of how you can remove pipe characters from strings in JavaScript using the replace() function.

var someString = "|This is |a |string with pipe characters|";

someString = someString.replace(/\|/g, '');

console.log(someString);

#Output:
This is a string with pipe characters
