它可以简化为:

<button onclick="return confirm('Are you sure you want to delete?');" />

<form onsubmit="return confirm('Are you sure?');" />

适用于表单。表单特定的问题:JavaScript表单提交-确认或取消提交对话框

onclick处理程序应该在函数调用后返回false。如。

onclick = " ConfirmDelete ();返回错误;" >

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>

<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);

                }
            }
        });
}

您可以更好地使用以下方法

 <a href="url_to_delete" onclick="return confirm('Are you sure you want to delete this item?');">Delete</a>
