我想要得到一个确认消息点击删除(这可能是一个按钮或图像)。如果用户选择“Ok”,那么删除就完成了,否则如果点击“Cancel”,什么都不会发生。
当点击按钮时,我尝试回显这个,但是回显的东西使我的输入框和文本框失去了它们的样式和设计。

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>

function confirmDelete()
{
var r=confirm("Are you sure you want to delte this image");
if (r==true)
{
//User Pressed okay. Delete
}
else
{
//user pressed cancel. Do nothing
}
}
<img src="deleteicon.png" onclick="confirmDelete()">
您可能希望使用confirmDelete传递一些数据,以确定要删除哪个条目
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>
下面是纯JS中使用className和绑定事件的另一个简单例子。
var eraseable = document.getElementsByClassName("eraseable"); for (var i = 0; i < eraseable.length; i++) { eraseable[i].addEventListener('click', delFunction, false); //bind delFunction on click to eraseables } function delFunction(){ var msg = confirm("Are you sure?"); if (msg == true) { this.remove(); //remove the clicked element if confirmed } }; <button class="eraseable"> <img class="eraseable" src="http://zelcs.com/wp-content/uploads/2013/02/stackoverflow-logo-dumpster.jpg" style="width:100px;height:auto;"> Delete me</button> <button class="eraseable"> <img class="eraseable" src="http://zelcs.com/wp-content/uploads/2013/02/stackoverflow-logo-dumpster.jpg" style="width:100px;height:auto;"> Delete me</button> <button class="eraseable"> <img class="eraseable" src="http://zelcs.com/wp-content/uploads/2013/02/stackoverflow-logo-dumpster.jpg" style="width:100px;height:auto;"> Delete me</button>
HTML:
<a href="#" class="delete" data-confirm="Are you sure to delete this item?">Delete</a>
使用jQuery:
$('.delete').on("click", function (e) {
e.preventDefault();
var choice = confirm($(this).attr('data-confirm'));
if (choice) {
window.location.href = $(this).attr('href');
}
});
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
