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。

function myConfirm() {
  var result = confirm("Want to delete?");

实践

<form name=myform>
<input type=button value="Try it now" 
onClick="if(confirm('Format the hard disk?'))
alert('You are very brave!');
else alert('A wise decision!')">
</form>

Web最初:

对于“删除确认消息”使用:

                       $.ajax({
                        type: "POST",
                        contentType: "application/json; charset=utf-8",
                        url: "Searching.aspx/Delete_Student_Data",
                        data: "{'StudentID': '" + studentID + "'}",
                        dataType: "json",
                        success: function (data) {
                            alert("Delete StudentID Successfully");
                            return true;
                        }

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>

我想提供我的方法:

<form action="/route" method="POST">
<input type="hidden" name="_method" value="DELETE"> 
<input type="hidden" name="_token" value="the_token">
<button type="submit" class="btn btn-link" onclick="if (!confirm('Are you sure?')) { return false }"><span>Delete</span></button>
</form>

HTML

<input onclick="return myConfirm();" type="submit" name="deleteYear" class="btn btn-danger" value="Delete">

Javascript

<script>
function myConfirm() {
  var result = confirm("Want to delete?");
  if (result==true) {
   return true;
  } else {
   return false;
  }
}
