Remove all br from string javascript

I have a string that i would like to remove all occurrences of


I tried this and it did not work.

    productName = productName.replace("
"," ");

However this worked but only for the first


    productName = productName.replace("<br>"," ");

How would I get it to work for all
in the string.

Edit: this is the string...

00-6189 Start Mech Switch<br>00-6189 Start Mech Switch<br>00-6189 Start Mech Switch<br>

My apologies for being a little misleading with the
as it should have been <br>

Using regular expression you can use this pattern

/(<|<)br\s*\/*(>|>)/g
productName = productName.replace(/(<|<)br\s*\/*(>|>)/g,' ');

That pattern matches

 
, 
,
,
,
,
 or <br>, <br/>, <br />

etc...

Looks like your string is encoded so use

productName = productName.replace(/<br>/g," ");

note the g after the regular expression which means globally, to match all occurrences.

You could use the g flag in your regular expression. This indicates that the replace will be performed globally on all occurrences and not only on the first one.

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

Of course you should be aware that this won't replace
nor
but only
.

See an example of this working on ideone.

UPDATE:

Now that you've provided an example with your input here's a working regex you might use to replace:

productName = productName.replace(/<br>/g, ' ');

I've not tested it but you could try something like this

productName.replace(/\/g,' ');

Remove all Line Breaks from a String in JavaScript #

Use the String.replace() method to remove all line breaks from a string, e.g. str.replace(/[\r\n]/gm, '');. The replace() method will remove all line breaks from the string by replacing them with an empty string.

Copied!
const str = 'a\n multi \n line \r string \n!';

const withoutLineBreaks = str.replace(/[\r\n]/gm, '');
console.log(withoutLineBreaks); // 👉️ a multi line string !

We passed a regular expression to the String.replace method.

The forward slashes / / mark the beginning and end of the regular expression.

Let's first cover the g and m flags at the end of the regex.

The g (global) flag is used to specify that we want to match all occurrences of the regex, and not just the first occurrence.

The m (multiline) flag is used to specify that we want to match occurrences over multiple lines.

The square brackets [] are called a character class and are used to match either of the characters between the brackets.

We want to replace both \r and \n because line breaks vary depending on the operating system.

For example, Windows uses \r\n as end of line character, whereas \n is the default in Unix.

The second parameter we passed to the String.replace method is the replacement for each match.

Copied!
const str = 'a\n multi \n line \r string \n!';

const withoutLineBreaks = str.replace(/[\r\n]/gm, '');
console.log(withoutLineBreaks); // 👉️ a multi line string !

For our purposes, we replace each occurrence of a line break with an empty string.

The String.replace() method doesn't mutate the original string, it returns a new string. Strings are immutable in JavaScript.
