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>

function ConfirmDelete()
{
  return confirm("Are you sure you want to delete?");
}


<input type="button" onclick="ConfirmDelete()">

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>

使用jQuery:

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

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。：）

<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>

<!-- language: lang-js -->
<script>
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);
            }
        }
    });
}
</script>
