jQueryUI对话框替换确认？ [英] jQueryUI dialog replacement for confirm?

问题描述

我试图用jQueryUI对话框覆盖默认确认框，这是我的尝试：

I am trying to override the default confirmation box with the jQueryUI dialog box, and here is my attempt:

window.confirm = function (message_confirm) {
        $(document.createElement('div'))
            .attr({ title: 'Please confirm', 'class': 'confirm', 'id': 'dialogconfirm' })
            .html(message_confirm)
            .dialog({
                buttons: { YES: function () { return true; }, NO: function () { $(this).dialog('close'); } },
                close: function () { $(this).remove(); },
                draggable: true,
                modal: true,
                resizable: false,
                width: 'auto',
                hide: { effect: "fade", duration: 300 },

            });

    };

一旦运行此脚本，调用常规确认显示jQueryUI对话框，但 YES 选择不起作用。我有一个像下面这样的ajax调用：

This works in that once this script is run, calling a regular confirm shows the jQueryUI dialog, however, the YES selection does not work. I have an ajax call like below:

if (confirm("Are you sure you want to delete this user?"))
{
      alert("test");
     //ajax call
}
return false;

并且没有出现测试警报。对话框的NO选择工作正常。如何让YES工作？

And the test alert did not appear. The NO slection of the dialog works fine. How can I get the YES to work?

谢谢。

推荐答案

因为对话框是异步的，你可以使用延迟方法：

Because the dialog is asynchronous you can use a deferred approach:

window.confirm = function (message_confirm) {
  var defer = $.Deferred();
  $('<div/>', {title: 'Please confirm', 'class': 'confirm', 'id': 'dialogconfirm', text: message_confirm})
  .dialog({
    buttons: {
      YES: function () {
        defer.resolve("yes");
        $(this).attr('yesno', true);
        $(this).dialog('close');
      }, NO: function () {
        defer.resolve("no");
        $(this).attr('yesno', false);
        $(this).dialog('close');
      }
    },
    close: function () {
      if ($(this).attr('yesno') === undefined) {
          defer.resolve("no");
      }
      $(this).remove();
    },
    draggable: true,
    modal: true,
    resizable: false,
    width: 'auto',
    hide: {effect: "fade", duration: 300}
  });
  return defer.promise();
};

$(function () {
  confirm("Are you sure you want to delete this user?").then(function(yesno) {
    console.log(yesno);
  });
});
