javascript的作品，但聯繫表格仍然發送郵件

我有一個聯繫頁面，我使用JavaScript來作出「驗證碼」。所以peaople必須做一個數學，如果這是正確的，他們可以給我發一封電子郵件。現在我的問題是，javasctipt警告數學是錯誤的或沒有填寫，但電子郵件仍然被視爲。

我的html：

<script type="text/javascript"> 
function validate() { 
    var ta = document.getElementById("ta").value; 
    var answer = document.getElementById("answer").value; 
    var digit1 = parseInt(document.getElementById("digit1").innerHTML); 
    var digit2 = parseInt(document.getElementById("digit2").innerHTML); 
    var sum = digit1+ digit2; 
    if (answer === null || answer === "") { 
    alert("reken de cijfers uit"); 
    return false; 
    } else if (answer != sum){ 
    alert("je som is fout"); 
    } else if (ta === null || ta === ""){ 
    alert("schrijf een bericht"); 
    } else { 
    document.getElementById("answer").innerHTML = "bezig met sturen"; 
    document.getElementById("answer").innerHTML = ""; 
    } 
} 

function randNums() { 
    var rand_num1 = Math.floor(Math.random()*10)+1; 
    var rand_num2 = Math.floor(Math.random()*10)+1; 
    document.getElementById("digit1") .innerHTML=rand_num1; 
    document.getElementById("digit2") .innerHTML=rand_num2; 
} 

</script> 

<body onload="randNums() ;">

您應該顯示php以及伴侶。 – Darren

我不使用PHP，因爲遠程登錄我的提供商不支持PHP ... –

你的驗證函數需要返回FALSE的所有錯誤，從停止提交表單。你似乎只有一個錯誤。

function validate() { 
    var ta = document.getElementById("ta").value; 
    var answer = document.getElementById("answer").value; 
    var digit1 = parseInt(document.getElementById("digit1").innerHTML); 
    var digit2 = parseInt(document.getElementById("digit2").innerHTML); 
    var sum = digit1+ digit2; 
    if (answer === null || answer === "") { 
    alert("reken de cijfers uit"); 
    return false; 
    } else if (answer != sum){ 
    alert("je som is fout"); 
    return false; 
    } else if (ta === null || ta === ""){ 
    alert("schrijf een bericht"); 
    return false; 
    } else { 
    document.getElementById("answer").innerHTML = "bezig met sturen"; 
    document.getElementById("answer").innerHTML = ""; 
    } 
}
