Regex To allow Only number comma separated

Question

I want to add JavaScript validation to my input.

The Form is generated dynamically as per the information from database. I have field called regex where i store the expression to be applied to that field So I fetch the regex but how to apply it to the form ? I want to allow only comma separated numbers how to do this:

This is my generated HTML

<tr>
    <td>Codec</td>
    <td><input type="text" name="Codec" value="8"/></td>
</tr>

This is the regex i want to apply to my input : ^[0-9 _ ,]*$

What should be my java-script to check the input?

It depends on what kind of validation you mean. For an on-submit validation, you can use ``. — Wiktor Stribiżew, Mar 14 '16 at 08:50
@WiktorStribiżew So Easy ? Just need to add pattern and then the regex i want to apply ? — Rajan, Mar 14 '16 at 08:51
Why do you add `/`s? `pattern` attribute only accepts a string, not a RegExp object. — Wiktor Stribiżew, Mar 14 '16 at 08:54
No, `^` and `$` are added by default. The final regex that will be applied is `^(?:[0-9 _,]*)$`. — Wiktor Stribiżew, Mar 14 '16 at 08:54

You can validate the input on the html input tag. Just use pattern="[0-9 _,]*"
