onclick处理程序应该在函数调用后返回false。如。

onclick = " ConfirmDelete ();返回错误;" >

我认为最简单不显眼的解决方案是:

链接:

<a href="http://link_to_go_to_on_success" class="delete">Delete</a>

Javascript:

$('.delete').click(function () {
    return confirm("Are you sure?");
});

<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>

<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

我用这种方法(laravel)-

<form id="delete-{{$category->id}}" action="{{route('category.destroy',$category->id)}}" style="display: none;" method="POST">
 @csrf
 @method('DELETE')
</form>

<a href="#" onclick="if (confirm('Are you sure want to delete this item?')) {
           event.preventDefault();
           document.getElementById('delete-{{$category->id}}').submit();
         }else{
           event.preventDefault();
         }">
  <i class="fa fa-trash"></i>
</a>

我想提供我的方法:

<form action="/route" method="POST">
<input type="hidden" name="_method" value="DELETE"> 
<input type="hidden" name="_token" value="the_token">
<button type="submit" class="btn btn-link" onclick="if (!confirm('Are you sure?')) { return false }"><span>Delete</span></button>
</form>
