replace all </script> tags with <\/script> in javascript or jquery

问题

I need to replace all these tags </script> with these tags </script>

Before: -> <script>..code..</script> <script>..code..</script>

After: ---> <script>..code..<\/script> <script>..code..<\/script>

But this does not work:

function myReplace(){
    var X = document.getElementById("demo").innerText;
    var Y = X.replace(/</script>/ig, '<\/script>');
    document.getElementById("demo").innerText = Y;
}

DEMO

Here's a related post for a better understanding

It looks like your expression isn't going to work. Your slashes aren't being escaped properly. Try this.

function myReplace(){
   var X = document.getElementById("demo").innerHTML;
   var Y = X.replace(/<\/script>/ig, "<\\\/script>");
   document.getElementById("demo").innerText = Y;
}

I also found a good article about how to do this and why. They go to the extent of escaping your < and > sign's, but I believe escaping your your forward slashes is the most important.
