未提交HTML表單的Java腳本

Question

我正在使用以下JavaScript提交表單，但它未提交。

if(timeup) 
     { 
     alert("welcome to time up."); 
     var id = document.getElementById("test_id").value; 
     var no = document.getElementById("noq").value; 
     var action = 'result.php?id='+id+'&no='+no+''; 

    exercisenew.action = action; 
    alert("form"+exercisenew.action); 
    exercisenew.submit(); 
     alert("form submitted."); 
    } 

完整代碼here。

Html表單。

<form method="post" action="" id="exercisenew" name="exercisenew"> 

Answer 1

創建exercisenew

var exercisenew = document.getElementById("exercisenew") 

對象，並盡一切你都做

Answer 2

if(timeup) 
{ 
    alert("welcome to time up."); 
    var id = document.getElementById("test_id").value; 
    var no = document.getElementById("noq").value; 

    //use encodeURIComponent() 
    var action = encodeURIComponent('result.php?id='+id+'&no='+no+''); 

    //get the form 
    var exercisenew = document.getElementById("exercisenew") 
    exercisenew.action = action; 

    alert("form"+exercisenew.action); 
    exercisenew.submit(); 
    alert("form submitted."); 
}
