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>

如果你对一些快速漂亮的解决方案与css格式感兴趣，你可以使用SweetAlert

$(function(){ $(".delete").click(function(){ swal({ title: "Are you sure?", text: "You will not be able to recover this imaginary file!", type: "warning", showCancelButton: true, confirmButtonColor: "#DD6B55", confirmButtonText: "Yes, delete it!", closeOnConfirm: false }).then(isConfirmed => { if(isConfirmed) { $(".file").addClass("isDeleted"); swal("Deleted!", "Your imaginary file has been deleted.", "success"); } }); }); }); html { zoom: 0.7 } /* little "hack" to make example visible in stackoverflow snippet preview */ body > p { font-size: 32px } .delete { cursor: pointer; color: #00A } .isDeleted { text-decoration:line-through } <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script> <script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script> <link rel="stylesheet" href="http://t4t5.github.io/sweetalert/dist/sweetalert.css"> <p class="file">File 1 <span class="delete">(delete)</span></p>

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>

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。：）

<form onsubmit="return confirm('Are you sure?');" />

适用于表单。表单特定的问题:JavaScript表单提交-确认或取消提交对话框

使用jQuery:

$(".delete-link").on("click", null, function(){
        return confirm("Are you sure?");
    });
