例如我想在10.00.00.00 am调用js函数,我该怎么办?
<script type="text/javascript"> var now = new Date(); var millisTill10 = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 0, 30, 0, 0) - now; setTimeout(function{openAPage(), setInterval(openAPage, 60*1000)}, millisTill10) function openAPage() { var startTime = new Date().getTime(); var myWin = window.open("http://google.com","_blank") var endTime = new Date().getTime(); var timeTaken = endTime-startTime; document.write("<br>button pressed@</br>") document.write(new Date(startTime)); document.write("<br>page loaded@</br>") document.write(new Date(endTime)); document.write("<br>time taken</br>") document.write(timeTaken); myWin.close() } </script>
我希望从此代码在00.30开始打开google,然后每隔1分钟就会再次打开它?该代码有什么问题?
您将需要setTimeout来设置计时器,并需要Date来计算计时器需要多长时间才能触发。
var now = new Date(); var millisTill10 = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 10, 0, 0, 0) - now; if (millisTill10 < 0) { millisTill10 += 86400000; // it's after 10am, try 10am tomorrow. } setTimeout(function(){alert("It's 10am!")}, millisTill10);
