javascript弹出问题在Internet Explorer中！ [英] javascript popup issue In Internet Explorer !

问题描述

我在用javascript打开弹出窗口时遇到问题，我有此功能在IE6和IE7中打开弹出窗口:

i have Problem with opening popups in javascript i have this function to open my popups in IE6 and IE7:

function open_window(Location,w,h) //opens new window
{
  var win = "width="+w+",height="+h+",menubar=no,location=no,resizable,scrollbars,top=500,left=500";
  alert(win) ;
  window.open(Location,'newWin',win).focus();

}

正在工作.我的意思是我的新窗口打开，但是发生错误.错误消息是:

it's working . i mean my new window opens but an error occurs. The Error Message is :

'window.open(...)'为null不是对象.
您要在此页面上计算运行脚本吗?

'window.open(...)' is null is not an object.
do you want to countinue running script on this page ?

然后我在onclick事件中有一个按钮，它将调用一个函数来关闭当前窗口并刷新打开器功能

then i have button in onclick event it's will call a function to close current window an refresh the opener function is

function refreshParent(location) 
{
  window.opener.location.href = location ; 
  window.close();
}

它也给我错误:window.opener.location为null或不是对象，但我确定我传递了正确的参数

it's also gives me error : window.opener.location is null or not an object but i'm sure i'm passing correct parameters

我这样称呼它:

第二部分:

<input type="button" name="pay" value="test" onclick="refreshParent('index.php?module=payment&task=default')" >

第一部分:

<a onclick="javascript:open_window('?module=cart&task=add&id=<?=$res[xproductid]?>&popup=on','500' , '500')"  style="cursor:pointer" id="addtocard"> <img src="../images/new_theme/buy_book.gif" width="123" border="0"/> </a>

这真的使我感到困惑.请帮助;)

it's really confuse me . Please Help ;)

推荐答案

使用window.open打开的弹出窗口被弹出窗口阻止程序阻止，这是当今几乎所有现代浏览器的功能，即window.open的返回值. ()不是窗口对象，但为null.

When popup windows opened using window.open are blocked by a popup blocker, a feature of pretty much any modern browser these days, the return value of window.open() is not a window object, but null.

为了避免这些问题，您需要在尝试调用window.open()返回的任何值之前对其进行测试.

In order to circumvent these issues you would need to test the value returned by window.open() before attempting to invoke any methods on it.

下面是一段代码，演示了如何解决此问题:

Below is a piece of code to demonstrate how to go around this problem:

function open_window(Location,w,h) //opens new window
{
  var options = "width=" + w + ",height=" + h;
  options += ",menubar=no,location=no,resizable,scrollbars,top=500,left=500";

  var newwin = window.open(Location,'newWin',options);

  if (newwin == null)
  {
    // The popup got blocked, notify the user
    return false;
  }

  newwin.focus();
}

通常，弹出窗口仅应在不得已时或在受控环境(公司内部网站等)中使用.弹出窗口阻止程序的行为往往会非常不一致，并且在给定的浏览器中可能安装了多个弹出窗口阻止程序，因此指导用户如何允许给定网站的弹出窗口不一定是一种解决方案.例如:IE7 + Google工具栏=两个弹出窗口阻止程序.

In general, popup windows should be used only as a last resort or in controlled environments (internal company website, etc). Popup blockers tend to behave in very inconsistent ways and there may be more than a single popup blocker installed in a given browser so instructing the user on how to allow popups for a given website is not necessarily a solution. Example: IE7 + Google toolbar = two popup blockers.

如果我建议的话，也许您应该考虑使用类似以下的方式: http://jqueryui.com/demos/dialog/

If I may suggest, perhaps you should consider using something like this: http://jqueryui.com/demos/dialog/

优点很多:

1. 皮肤漂亮，因此您可以创建更一致的外观以匹配您的网站.
2. 没有弹出窗口阻止程序.
3. 良好的API和文档，在大多数(即使不是全部)主要浏览器中也保持一致.

如果仍然要求新打开的窗口"包含外部URL，则可以在打开的对话框窗口中使用IFRAME.

If you still require that the newly opened "window" contain an external URL, you could use an IFRAME inside the opened dialog window.

希望这会有所帮助，
