RegEx for non-numeric + allow only single "." for input validation

Question

Kindly help me out for below requirement.

Here is my requirement

var a = "$150.00"

Now when user tab out on this input value; it should remain as it is. But it is getting as $15000

This is regex I am using.

this.value.split('').reverse().join('').replace(/[\D]/i,'').split('').reverse().join('');

Validation is happening on keydown event.

Add an optional period into the regex.

this.value.split('').reverse().join('').replace(/[\D]\.?[\D]/i,'').split('').reverse().join('');
