JavaScript setInterval調用form.submit

Question

我需要根據超時定時器提交表單。它不是調用表單提交。請給我建議

我打電話的document.ready

$(document).ready(function(){ 
    var duration = 60*20; 
    display = $('#timer'); 
    startTimer(duration, display); 

    $.fn.disableSelection = function() { 
    return this 
      .attr('unselectable', 'on') 
      .css('user-select', 'none') 
      .on('selectstart', false); 
    }; 

    $("#question_container").disableSelection(); 
}); 

function startTimer(duration, display) { 
    var timer = duration, minutes, seconds; 
    setInterval(function() 
    { 
     minutes = parseInt(timer/60, 10); 
     seconds = parseInt(timer % 60, 10); 

     minutes = minutes < 10 ? "0" + minutes : minutes; 
     seconds = seconds < 10 ? "0" + seconds : seconds; 

     display.text(minutes + ":" + seconds); 

     if (--timer < 0) { 
      $("#questionform").submit(); 
     } 
    }, 1000); 
} 
setInterval ("autosubmit()", 5000000); 
function autosubmit() 
{ 
document.theFormName.submit; 
} 

Answer 1

的startTimer所只要改變

setInterval ("autosubmit()", 5000000); 

到

setInterval (autosubmit, 5000000);

Answer 2

document.theFormName.submit;什麼也沒做。它只是訪問一個函數，然後忽略它。

如果你想調用它，那麼你確實有調用它：

document.theFormName.submit();
