我知道这是老问题了，但我需要一个答案，这些答案都不是，但alpesh的答案对我有用，我想与可能有同样问题的人分享。

<script>    
function confirmDelete(url) {
    if (confirm("Are you sure you want to delete this?")) {
        window.open(url);
    } else {
        false;
    }       
}
</script>

普通版:

<input type="button" name="delete" value="Delete" onClick="confirmDelete('delete.php?id=123&title=Hello')">

我的PHP版本:

$deleteUrl = "delete.php?id=" .$id. "&title=" .$title;
echo "<input type=\"button\" name=\"delete\" value=\"Delete\" onClick=\"confirmDelete('" .$deleteUrl. "')\"/>";

这可能不是公开的正确方式，但在一个私人网站上，这对我来说是有效的。：）

改进user1697128(因为我还不能评论它)

<script>
    function ConfirmDelete()
    {
      return confirm("Are you sure you want to delete?");
    }
</script>    
    
<button Onclick="return ConfirmDelete();" type="submit" name="actiondelete" value="1"><img src="images/action_delete.png" alt="Delete"></button>

如果按“取消”键，会取消提交表格吗

您可以更好地使用以下方法

 <a href="url_to_delete" onclick="return confirm('Are you sure you want to delete this item?');">Delete</a>

它可以简化为:

<button onclick="return confirm('Are you sure you want to delete?');" />

对于选择选项框，要做到这一点要困难得多。 下面是解决方案:

<select onchange="if (this.value == 'delete' && !confirm('THIS ACTION WILL DELETE IT!\n\nAre you sure?')){this.value=''}">
    <option value=''> &nbsp; </option>
    <option value="delete">Delete Everything</option>
</select>

我认为最简单不显眼的解决方案是:

链接:

<a href="http://link_to_go_to_on_success" class="delete">Delete</a>

Javascript:

$('.delete').click(function () {
    return confirm("Are you sure?");
});
