问题
My requirement is that i have a .php page that has to display some graphs/data based on data from a database. I would like refresh the page automatically and periodically so that graphs/data can be updated, as the data is obtained only on loading of the page. How can i do this ?
回答1:
Maybe you can try the setTimeout javascript method
setTimeout("location.reload(true);",timeoutPeriod);
this would refresh the page on every timeoutPeriod interval.
回答2:
You can use javascript.
JS function
function timedRefresh(timeoutPeriod) {
setTimeout("location.reload(true);",timeoutPeriod);
}
Add below line on body tag.
<body onload="JavaScript:timedRefresh(5000);"> // time : 5000= 5 secs
