获取用于 jQuery 操作的弹出窗口的 DOM 元素

2022-01-20 00:00:00 popup jquery javascript

我正在创建一个弹出窗口，如下所示:

I am creating a popup as follows:

   var comet = {

        popup: null, 

        newPopup: function(windowsname, w, h){
            this.popup = window.open(windowsname, windowsname, 'width=' + w + ',height=' + h);
            var self = comet;
            var logOut= null;
            $(this.popup.document).ready(function(){
                logOut = self.popup.document.getElementById('logout');
                console.log(logOut);
                $(logOut).live('click', function(){
                    alert('HELLO');
                    return false;
                })
            })
        },

        some_function: function(){
             //calling it here:
             this.newPopup('index.php',1120,550);
        }
    }

logOut 有时(通常在第一个窗口打开时)返回 null.此外，点击处理程序永远不会通过，原始点击处理程序会运行.

The logOut sometimes (usually on the 1st window open) returns null. Also, the click handler never goes through and the original click handler operates.

如何覆盖弹出窗口的真实点击处理程序?
这两个页面都在我的网站上，所以应该没有跨站问题..

How do I overwrite the real click handler of the popup?
Both pages are on my site, so there should be no cross site issues..

$(function()

        newPopup: function(url, w, h)
        {
            this.popup = window.open(url, url, 'width=' + w + ',height=' + h);
            var self = this;

            this.popup.onload = function ()
            {
              var doc = this.document,
                  script = doc.createElement('script');
              script.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js';
              script.onload = function ()
              {
                  function setup()
                  {
                      $('#logout').click(function () { alert('It worked!'); });
                  }

                  script = doc.createElement('script');
                  script.textContent = "(" + setup.toString() + ")();";
                  doc.body.appendChild(script);
              };

              doc.head.appendChild(script);
            };
        },

        foo: function()
        {
            this.newPopup('http://jsbin.com/amuza3/2', 600, 400);
        }
    };

    $('#clickme').click(function ()
    {
        comet.foo();
    });
});
