To split a string on every occurrence of ~, split the array. After splitting, add a line break i.e. <br> for each occurrence of ~.
This is demo text 1!~This is demo text 2!~~This is demo text 3!
After the split and adding line breaks like the following for ~ occurrence −
This is demo text 1! This is demo text 2! This is demo text 3!
Let’s see the complete example
<!DOCTYPE html> <html> <body> <h2>Adding line break</h2> <script> var myArray = 'This is demo text 1!~This is demo text 2!~ ~This is demo text 3!~This is demo text 4!~ ~This is demo text 5!'; document.write("Original Array: " +myArray); var brk = myArray.split('~'); var res = brk.join(" <br> "); document.write("<br><br>"+res); </script> <p>Each occurrence of ~ adds a line break above.</p> </body> </html>
