在點擊取消按鈕之後停留在當前頁面

Question

我在index.jsp中有一個表單，點擊提交後我顯示一條提示「confirm submit？」。如果ok將被點擊，然後確認將會顯示子目錄.jsp。我在0123ms收到confirmationmsubmit.jsp中的文本框名稱，但問題是如果我點擊取消然後confirmmsubmit.jsp正在打開，如何在alert中單擊取消按鈕後留在index.jsp中？

任何幫助，請

的index.jsp

<form action="confirmsubmit.jsp" method="POST"> 
<script type="text/javascript"> 
<!-- 
function confirmation() { 
var answer = confirm("Confirm submit?") 
if (answer){ 

    window.location = "confirmsubmit.jsp";// goes to confirmsubmit.jsp 
} 
else{ 
    //should remain in index.jsp but here also confirmsubmit.jsp is opening 
} 
} 
//--> 
</script> 
<input type="text" name="textboxname"/> 
<input type="submit" onclick="confirmation()"/> 
</form> 

Answer 1

添加以下的其他部分線路：

return false; 

，改變你的onclick到：

return confirmation(); 

= ==更新===

因爲你在表單動作有confirmsubmit.jsp，你不需要window.location：

function confirmation() { 
    if (!confirm("Confirm submit?")) { 
     return false; 
    } 
} 

另見。

    <script type="text/javascript"> 
    <!-- 
    function confirmation() { 
    var answer = confirm("Confirm submit?") 
    if (answer){ 

     window.location = "confirmsubmit.jsp";// goes to confirmsubmit.jsp 
     return true; 
    } 
    else{ 
     //should remain in index.jsp but here also confirmsubmit.jsp is opening 
    return false; 
    } 
    }

    </script> 
    <input type="text" name="textboxname"/> 
    <input type="submit" onclick="return confirmation()"/> 

</form> 

Answer 3

從onclick脫掉return並添加return false;如果!answer

<script type="text/javascript"> 
function confirmation() { 
    var answer = confirm("Confirm submit?") 
    if (!answer){ 
     return false; 
    } 
} 
</script> 

<form action="confirmsubmit.jsp" method="POST"> 
    <input type="text" name="textboxname"/> 
    <input type="submit" onclick="confirmation()"/> 
</form>
