如何在删除前显示确认消息?

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。

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>

它非常简单，只有一行代码

<a href="#" title="delete" class="delete" onclick="return confirm('Are you sure you want to delete this item')">Delete</a>

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

var txt;
var r = confirm("Press a button!");
if (r == true) {
   txt = "You pressed OK!";
} else {
   txt = "You pressed Cancel!";
}

var txt; var r =确认(“按下按钮!”); 如果(r == true) { txt = "You pressed OK!"; }其他{ txt = "You pressed Cancel!"; }

<script>
function deleteItem()
{
   var resp = confirm("Do you want to delete this item???");
   if (resp == true) {
      //do something
   } 
   else {
      //do something
   }
}
</script>

使用onClick调用此函数

试试这个。这对我很有用

 <a href="delete_methode_link" onclick="return confirm('Are you sure you want to Remove?');">Remove</a>
