This javascript will validate/allow the number only when event key is pressed.
For example result of it:
<iframe width="100%" height="350" src="//jsfiddle.net/agaust/3qz105nn/embedded/html,result/dark/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
\ No newline at end of file
<iframe width="100%" height="350" src="//jsfiddle.net/agaust/3qz105nn/embedded/html,result/dark/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
tutorial above, when you can not directly add the attribute inside html tag.
but if you can add it, you can following this bellow:
{% highlight html %}
<input id="id_price" type="number" min=0 onkeypress="return isNumber(event)"/>
<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;
}
</script>
{% endhighlight %}
hope it usefull.
