在表单提交之前确认

Question

我找了一个答案却找不到答案!

我有一个简单的表格,

<form action="adminprocess.php" method="POST">
    <input type="submit" name="completeYes" value="Complete Transaction" />
</form>

在处理表格之前,我该如何调整以确认？

我试过onclick,但无法让它工作.

有任何想法吗？

更新 - 我现在拥有的.

<script type="text/javascript">
var el = document.getElementById('myCoolForm');

el.addEventListener('submit', function(){
return confirm('Are you sure you want to submit this form?');
}, false);
</script>

<form action="adminprocess.php" method="POST" id="myCoolForm">
     <input type="submit" name="completeYes" value="Complete Transaction" />
</form>

Answer 1

HTML:

<form action="adminprocess.php" method="POST" id="myCoolForm">
    <input type="submit" name="completeYes" value="Complete Transaction" />
</form>

JavaScript的:

var el = document.getElementById('myCoolForm');

el.addEventListener('submit', function(){
    return confirm('Are you sure you want to submit this form?');
}, false);

编辑:你总是可以像这样使用内联JS代码:

<form action="adminprocess.php" method="POST" onsubmit="return confirm('Are you sure you want to submit this form?');">
    <input type="submit" name="completeYes" value="Complete Transaction" />
</form>

Answer 2

<input type="submit" onclick="return confirm('Are you sure you want to do that?');">
