To replace the dots in a string, you need to escape the dot (.) and replace using the replace() method.
Example
You can try to run the following code to replace all dots in a string −
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<script>
var str = 'Demo.Text.with.dots';
document.write("Text with dots- "+str);
var res = str.replace(/\./g,' ');
document.write("<br>Text without dots- "+res);
</script>
</body>
</html>
