document.getElementById('id').src =不从缓存重新加载 [英] document.getElementById('id').src = reload not from cache
问题描述
无法从缓存中重新加载元素会遇到问题.
i´ve a problem by reload elements not from cache.
第一拳，我的头
<meta http-equiv="expires" content="0"><!-- no cache-->
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-store" />
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"/>
<meta http-equiv="content-script-type" content="text/javascript">
因此，我在.php编写和更改的外部.txt文档中使用了JavaScript var 我的任务是将该变体实现为HTML，并每10秒保持它们不变. 我使用了以下代码:
So I´ve JavaScript var in external .txt documents written and changed by .php My task is to implement this var into HTML and keep them actual every 10 sec. I used following code:
<script type="text/javascript" id="Perso_UHS_1"></script>
<script>
function reldataperso(){
var dper = new Date();
document.getElementById('Perso_UHS_1').src =
"PersonalkapazitatUHS1.txt?time" + dper.getTime();
};
setInterval(function(){
reldataperso();
alert("test")
}, 10000);
</script>
</head>
<body onload="reldataperso()">
好的，这适用于.jpg或.html，但不适用于头部的.txt.浏览器不要尝试重新加载，因为警报每10秒就要来一次...
OK, this works with .jpg oder .html but not by .txt in the head. The Browser don´t try to reload, by the alert was coming every 10 seconds...
你有什么主意吗?
推荐答案
您对'cache-control'的定义有误，也许可以解决
You have the 'cache-control' one wrong defined, maybe it fixes it
<meta http-equiv='cache-control' content='no-cache'>
