This javascript will validate/allow the number only when event key is pressed.
{% highlight html %}
<input id="id_price" type="number" min=0 />
<script type="text/javascript">
function isNumber(evt) {
evt = (evt) ? evt : window.event;
var charCode = (evt.which) ? evt.which : evt.keyCode;
if (charCode > 31 && (charCode < 48 || charCode > 57)) {
return false;
}
return true;
}
document.getElementById('id_price').setAttribute("onkeypress", "return isNumber(event)");
</script>
{% endhighlight %}
For example result of it:
<script async src="//jsfiddle.net/agaust/3qz105nn/embed/html,result/dark/"></script>
