Using regular expressions in JavaScript to substitute an equal sign that is immediately followed by a line break

I need help creating a regex expression that will remove equal signs followed by a new line.

For instance, the text below shows each line ending with an equals sign and a new line character.

<p style=3D"border-bottom: 1px solid lightgrey; padding-bottom: 10px; margi=
n-bottom: 10px">From @mytwitterrrr filtered:<br></p><div><div><a href=3D"ht=
tps://feeder.co/p/076b2f56-af6c-11eb-adf3-1a21cf3a468a?u=3Da6566144-b0a5-4d=

I want to specifically target and replace equal signs occurring at end of each line without affecting other occurrences in the text.

let modified = message.replace(/\n*.+=/g,',')

Any assistance with this would be greatly appreciated! Thank you.

Answer №1

This code snippet should solve the issue:

/=\n/g, ''


const inputString = `<p style=3D"border-bottom: 1px solid lightgrey; padding-bottom: 10px; margi=
n-bottom: 10px">From @sl_steamroom filtered:<br></p><div><div><a href=3D"ht=
tps://feeder.co/p/076b2f56-af6c-11eb-adf3-1a21cf3a468a?u=3Da6566144-b0a5-4d=
`
const outputString = inputString.replace(/=\n/g, '');

document.querySelector('#div').innerHTML = outputString
console.log(outputString)
<div id="div"></div>

Answer №2

The following script will substitute every occurrence of = that is immediately followed by a line break, without replacing the line break character itself.

let modified = text.replace(/=(?=\n)/g,',')

This is achieved by utilizing a look-ahead mechanism (?=\n) which scans for the newline character \n ahead.
