如何让我的页面只刷新一次？

Question

Js:

<script type="text/javascript">

function timedRefresh(timeoutPeriod) {

  var refreshed=true;

  if(refreshed){

    refreshed=false;

    setTimeout("location.reload();",timeoutPeriod);
  }

}
</script>

Html

body onload="JavaScript:timedRefresh(5000);"

i can not get it to load only once its keeps reloading instead of taking the new value

Answer 1

重新加载页面将再次触发加载事件，这将再次重新加载页面...您应该使用cookie或其他客户端数据存储来了解页面是否已加载一次。

Answer 2

You are making the assumption that the browser is keeping the javascript variable values between each page load, but everything is flushed. You might want to use HTML5 local storage so that state is persisted between pages.
