问题
I am trying to autoreload my page after every 20 seconds. I am using JavaScript for this instead of the <meta>.
I have <body onload="SetTimer()"> and here is my JavaScript function
function SetTimer(){
setTimeout('window.location.replace(window.location.pathname)', 20000)
}
Now my problem is I also pass a parameter within the querystring when this page is loaded first. But when the page relaods again (window.location.pathname does not include the parameter) hence I am not able to assign values to the labels on the page which is based on the parameters passed.
回答1:
Simple page reload also does a trick
function SetTimer(){
setTimeout('window.location.reload(true)', 20000)
}
回答2:
setTimeout('window.location.replace(window.location.href)', 2000);
did the trick
回答3:
window.location will include the GET parameters that were that was passed.
function SetTimer(){
setTimeout('window.location.replace(window.location)', 20000)
}
If you are submitting parameters through POST, the best method will probably be to create a form with hidden inputs for each parameter. Submit the form every twenty seconds.
