String replace in javascript not working properly

Question

<?php
$str = "this is a . test . string.";
?>

<script>
    var str = '<?php echo $str; ?>';
    wordss = ' . ';
    var res = str.replace(new RegExp(wordss,"g"),". "); //space(.)space convert to (.)space
    console.log(res);
</script>

Output

this is. . test. string.

I want it in "this is a. test. string."

var res = str.replace(/ \. /g, ". "); - you have to quote the . character, and it's easier to use regex literals. — Pointy

Also, you will want to do: var str = <?php echo json_encode($str); ?>; to avoid special characters from spilling over into your JavaScript. — Halcyon

var str = "this is a . test . string.";
var res = str.split(" . ").join(". ");
console.log(res);

Use RegExp /\s+(?=\.)/g to match space character that is followed by . character

var str = "this is a . test . string."
str = str.replace(/\s+(?=\.)/g, "");
document.body.textContent = str;
