使用jQuery:

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

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


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

<SCRIPT LANGUAGE="javascript">
function Del()
{
var r=confirm("Are you sure?")
if(r==true){return href;}else{return false;}
}
</SCRIPT>

你的链接:

<a href='edit_post.php?id=$myrow[id]'> Delete</a>

<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);

                }
            }
        });
}

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>

在按钮的onclick事件中写入以下内容:

var result = confirm("Want to delete?");
if (result) {
    //Logic to delete the item
}
