如果满足条件，则自动单击“提交”按钮

Question

I am making an online examination system in PHP.this is a part of my huge examination code..every thing is working well.When the time is up, the page is redirecting to result page by

window.location = "http://localhost/result.php";//which is in comment line

but here the value of answers are not posting. But when i click the submit button it works. So i make a function to submit the form automatically.but it is not working , dont know why. Here "if" block is checking whether the time is up or not. if up then do the following. Inside "if" I want either to click the "submit button"

 echo '<input type="submit" name="submit" id="submit" value="SUBMIT"/></FORM>'; 

or submit the the form, so that i can get the result in next page- "result.php".

<FORM name ='form1' id='form1' method ='post' action='result.php' >

Thanks in advance. Hope you understand my problem.

function myfunc () {
    var frm = document.getElementById("form1");
    frm.submit();
}

document.getElementById("remain").innerHTML = hours+" hours : "+minutes+" minutes : "+seconds+" seconds";
SD=window.setTimeout( "setCountDown()", 1000 );
if (minutes == '00' && seconds == '00') { seconds = "00"; window.clearTimeout(SD);
    window.alert("Time is up. Press OK to continue.");
    window.onload = myfunc;
    //document.form1.submit();
    //window.location = "http://localhost/result.php"
}

Answer 1

Try this..

window.onload = function(){
    myfunc();
};

Answer 2

If you're trying to submit the form after window.alert("Time is up. Press OK to continue.") shows, you don't need a load event. You can just put your code immediately after the alert and it will run once the alert is closed (by clicking 'okay'):

alert("Time is up. Press OK to continue.");
myfunc();

Alternatively, you could use confirm instead of alert :

var timesUp = confirm("Time is up. Press OK to continue.");

if (timesUp) {
    myfunc();
}

With a confirm you'll get two buttons and could run a different event for ok (true) and cancel (false). One of these options should solve your problem though.

只需使用此document.form1.submit.click（）;
