Answer 1

This one function would do what you want :

Javascript:

document.getElementById("date").onkeyup=function(){
   return false;
}

And here is HTML :

<input id="date" type="date">

See this JS Fiddle Demo . Hope this helps.

Answer 2

您可以使用 Onchange 事件，然后检查输入是否为数字http://www.w3schools.com/jsref/event_onchange.asp
