Question

我想在删除一些数据之前做出确认，那么我怎样才能使用jquery？

Answer 1

$('#deleteBtn').click(function() {
  if(confirm("Are you sure?")) {
    //delete here
  }
});

Answer 2

一种可能性是使用javascript confirm函数。

$(function() {
    $('#someLink').click(function() {
        return confirm('Are you sure you want to delete this item?');
    });
});

Answer 3

要进行对话，请使用jQueryUI dialog。它包括模态和非模态对话框以及良好的视觉效果和强大的日期选择器。还有一些插件可用于扩展jQueryUI。

    var button = $("<span>Kill</span>").appendTo("#killer").click(function () {
        var form = $("#killer")

        $(dialog).dialog(

                title: "Confirm",
                modal: true,
                buttons: {
                    "Delete em": function () {
                        // This will invoke the form's action - putatively deleting the resources on the server
                        $(form).submit();
                        $(this).dialog("close");
                    },
                    "Cancel": function() {
                        // Don't invoke the action, just close the dialog
                        $(this).dialog("close");
                    }
                }
            });
        return false;
    });
    // Use jQuery UI styling for our button
    $(button).button();
}
</script>

<body onload="setupKiller();">
<form id='killer' method='POST'>
<p>Some Text</p>
</form>
</body>
