Don't allow typing alphabetic characters in a <input type=number />

Question

I need to have a textbox, where, whenever typed inside should ONLY allow numbers [0-9]. I\'ve used type=\"number\" which definitely holds the client side valida

Answer 1

You will have to have your input box inside a form and with a submit button. The form validation happens at the submission of the form. See a demo here: http://jsfiddle.net/ds345/Q4muA/1/

<form>Number:
    <input type="number" name="Number" value="10">
    <br>
    <input type="submit" value="Submit" />
</form>

Answer 2

Try this:-

 $("#txtAge").keydown(function (e) {
       if(e.key=='e' || e.key=='.' || e.key=='-')
        return false;
    });

Answer 3

Browsers behave differently. In Chrome the following code:

<input type="number" id="txt_number" maxlength="70" name="txt_name" placeholder="Number">
  <input type="submit">

will work for you only if it is in a form and only after the user clicks the submit button.
