本文實例講述了JS控制按鈕10秒鐘後可用的方法。分享給大家參考,具體如下:
<script language="javascript"> function start() { document.getElementById("Button1").disabled = true; document.getElementById("Button1").value = 10; window.setTimeout("tick()",1000); } function tick() { var time = new Number(document.getElementById("Button1").value); if(time>0) { document.getElementById("Button1").value = time-1; window.setTimeout("tick()",1000); } else { document.getElementById("Button1").disabled = false; document.getElementById("Button1").value = "保存"; } } </script> <form> <INPUT TYPE="button" NAME="Button1" id="Button1"> </form> <script language=javascript> start(); </script>
希望本文所述對大家JavaScript程式設計有所幫助。
