如何從iframe調用這個jQuery函數？

我想從一個iframe中調用一個jQuery彈出窗口函數。如何從iframe調用這個jQuery函數？

在我的外部.js文件包含在我父框架我有這樣的：

(function($){   
    $.fn.popupWindow = function(instanceSettings){ 

     return this.each(function(){ 

     $(this).click(function(){ 

     $.fn.popupWindow.defaultSettings = { 
      centerBrowser:0, // center window over browser window? {1 (YES) or 0 (NO)}. overrides top and left 
      centerScreen:0, // center window over entire screen? {1 (YES) or 0 (NO)}. overrides top and left 
      height:500, // sets the height in pixels of the window. 
      left:0, // left position when the window appears. 
      location:0, // determines whether the address bar is displayed {1 (YES) or 0 (NO)}. 
      menubar:0, // determines whether the menu bar is displayed {1 (YES) or 0 (NO)}. 
      resizable:0, // whether the window can be resized {1 (YES) or 0 (NO)}. Can also be overloaded using resizable. 
      scrollbars:0, // determines whether scrollbars appear on the window {1 (YES) or 0 (NO)}. 
      status:0, // whether a status line appears at the bottom of the window {1 (YES) or 0 (NO)}. 
      width:500, // sets the width in pixels of the window. 
      windowName:null, // name of window set from the name attribute of the element that invokes the click 
      windowURL:null, // url used for the popup 
      top:0, // top position when the window appears. 
      toolbar:0 // determines whether a toolbar (includes the forward and back buttons) is displayed {1 (YES) or 0 (NO)}. 
     }; 

     settings = $.extend({}, $.fn.popupWindow.defaultSettings, instanceSettings || {}); 

     var windowFeatures = 'height=' + settings.height + 
           ',width=' + settings.width + 
           ',toolbar=' + settings.toolbar + 
           ',scrollbars=' + settings.scrollbars + 
           ',status=' + settings.status + 
           ',resizable=' + settings.resizable + 
           ',location=' + settings.location + 
           ',menuBar=' + settings.menubar; 

       settings.windowName = this.name || settings.windowName; 
       settings.windowURL = this.href || settings.windowURL; 
       var centeredY,centeredX; 

       if(settings.centerBrowser){ 

        if ($.browser.msie) {//hacked together for IE browsers 
         centeredY = (window.screenTop - 120) + ((((document.documentElement.clientHeight + 120)/2) - (settings.height/2))); 
         centeredX = window.screenLeft + ((((document.body.offsetWidth + 20)/2) - (settings.width/2))); 
        }else{ 
         centeredY = window.screenY + (((window.outerHeight/2) - (settings.height/2))); 
         centeredX = window.screenX + (((window.outerWidth/2) - (settings.width/2))); 
        } 
        window.open(settings.windowURL, settings.windowName, windowFeatures+',left=' + centeredX +',top=' + centeredY).focus(); 
       }else if(settings.centerScreen){ 
        centeredY = (screen.height - settings.height)/2; 
        centeredX = (screen.width - settings.width)/2; 
        window.open(settings.windowURL, settings.windowName, windowFeatures+',left=' + centeredX +',top=' + centeredY).focus(); 
       }else{ 
        window.open(settings.windowURL, settings.windowName, windowFeatures+',left=' + settings.left +',top=' + settings.top).focus(); 
       } 
       return false; 
      }); 

     }); 
    }; 
})(jQuery);

在我父框架我有這樣的：

<script type="text/javascript" src="...jquery.js"></script> 
<script type="text/javascript"> 
$(document).ready(function(){ 
    $('.popit').popupWindow({ 
     height:350, 
     width:450, 
     centerBrowser:1 
    }); 
}); 
</script>

如果我把下面一行在我父框架我得到預期的結果 - 彈出作品：

<a href="http://www.bbc.co.uk" title="bbc.co.uk" class="popit" name="windowx">BBC<a/>

popupWindow函數與p opit類 - 沒問題。但是，如何修改上述代碼以便從iframe中調用此函數，以及iframe中的JavaScript是如何實現的？

'調用從你的意思是一個iframe'此功能，彈出的iframe或點擊（或其他事件）的iframe創建彈出？ – 2010-09-14 13:45:48

爲什麼你不能在頁面中使用Javascript和所有內容，只需使用頁面中的Javascript來控制iFrame？接縫更合乎邏輯，更直接。 – Frankie 2010-09-14 13:53:16

基本上我有一個應用程序在iframe中運行。當你嘗試從iframe進行oauth登錄時Twitter會打破iframe，因此我在彈出窗口中執行oauth。 – Owen 2010-09-14 15:38:49

這裏是爲您的iframe一些示例代碼：

<html> 
<head> 
    <title>sample code</title> 
<script type="text/javascript" src="./scripts/jquery.js"></script> 
    <script> 
     (function($){   
      $.fn.popupWindow = window.parent.$.fn.popupWindow; 
     })(jQuery); 
    </script> 
    <script type="text/javascript"> 
     jQuery(document).ready(function(){ 
      jQuery('.popit2').popupWindow({ 
       height:550, 
       width:650, 
       centerBrowser:1 
      }); 
     }); 
    </script> 
</head> 
<body> 

<a href="http://stackoverflow.com" title="stackoverflow.com" class="popit2" name="windowx">stackoverflow.com<a/> 

</body> 
</html>

通知代碼是如何達到最高的母體設定的iframe供本地使用的內部功能。
