页面加载后如何禁用提交按钮10秒钟

Question

My question is probably simple, but I'm only a week into programming, and I cant really understand the relative answers that I could find. So... need your Jedi help. How to disable a submit button for 10 seconds after the page is loaded? Thanks!

Answer 1

You can use javascript like this

<input type="submit" id="submitButton" disabled="disabled" />

using

<script type="text/javascript">
    window.onload=function() {
      setTimeout(function(){
        document.getElementById('submitButton').disabled = null;
      },10000);
    }
</script>

The following will additionally show a countdown in a container with ID="timeLeft" if you need one

 <script type="text/javascript">
    var countdownNum = 10;
    window.onload=function() {
      incTimer();
    }

    function incTimer(){
      setTimeout (function(){
        if(countdownNum != 0){
          countdownNum--;
          document.getElementById('timeLeft').innerHTML = 'Time left: ' + countdownNum + ' seconds';
          incTimer();
        } else {
          document.getElementById('submitButton').disabled = null;
          document.getElementById('timeLeft').innerHTML = 'Ready!';
        }
      },1000);
    }
</script>
