Question

Hi for the below javascript I want a regex which will replace all instances of left square bracket with \Left square bracket ,right square bracket with \ plus right square bracket or full stop with a \ dot

<script type="text/javascript" type="text/javascript">

        $(document).ready(function () {
            var someId = '#Something[0].AnotherSelected[5].Validator';

            alert(s);
        });

    </script>

Answer 1

var str = 'something[.something]].something[';
console.log(str.replace(/[\[\]\.]/g, '\\\\'));

Outputs

something\\\\something\\\\\\something\\';

[EDIT – based on the OP’s comment below:

console.log(str.replace(/[\[\]\.]/g, function($0) { return '\\\\'+$0; }))
