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>

<a href="javascript:;" onClick="if(confirm('Are you sure you want to delete this product')){del_product(id);}else{ }" class="btn btn-xs btn-danger btn-delete" title="Del Product">Delete Product</a>


function del_product(id){
    $('.process').css('display','block');
    $('.process').html('<img src="./images/loading.gif">');
    $.ajax({
        'url':'./process.php?action=del_product&id='+id,
        'type':"post",
        success: function(result){
            info=JSON.parse(result);
            if(result.status==1){
            setTimeout(function(){
                    $('.process').hide();
                    $('.tr_'+id).hide();
                },3000);
                setTimeout(function(){
                    $('.process').html(result.notice);
                },1000);
            }else if(result.status==0){
                setTimeout(function(){
                    $('.process').hide();
                },3000);
                setTimeout(function(){
                    $('.process').html(result.notice);
                },1000);

                }
            }
        });
}
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

当你在PHP和mysql中删除一些东西时,设置一个确认消息…

使用以下脚本代码:

<script>
    function Conform_Delete()
    {
       return conform("Are You Sure Want to Delete?");
    }
</script>

使用下面的HTML代码:

<a onclick="return Conform_Delete()" href="#">delete</a>
var x = confirm("Are you sure you want to send sms?");
if (x)
    return true;
else
    return false;
