通過javascript進行驗證後html-php表單提交

Question

我打算做的是：首先驗證表單，然後處理滿足一些條件的表單。下面我粘貼了我的代碼原型。 我已經交叉檢查任何次要/愚蠢的錯誤。由於

代碼：

<form id = "myform" action = process.php method = 'post'> 
//some form elements here 
<input type="submit" value="Submit this form"onclick="validate();return false;" /> 
</form> 

<script type="text/javascript"> 
function validate(){ 
if(validated) myform.submit(); 
else Alert(Some message); 
</script> 
} 

Answer 1

我認爲你需要做這樣的事情：

<form id="myform" action="process.php" method="post" onsubmit="return validate();"> 
//some form elements here 
<input type="submit" value="Submit this form" /> 
</form> 

<script type="text/javascript"> 
function validate(){ 
    ... 
    if(!valid) 
     alert('Error'); 
    return valid; 
} 
</script>
