window.opener.location not working in IE
提问by benjamin54
I'm trying to redirect from child page to parent page with this javascript:
我正在尝试使用此 javascript 从子页面重定向到父页面：
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Close", "ClosePopUp();", true);
<script language="javascript" type="text/javascript">
function ClosePopUp() {
window.opener.location= 'ParentPage.aspx';
self.close();
}
</script>
It works with Firefox & Chrome. But not with IE 9. The error I'm getting is:
它适用于 Firefox 和 Chrome。但不适用于 IE 9。我得到的错误是：
Unable to get value of the property 'location': object is null or undefined
Unable to get value of the property 'location': object is null or undefined
alert(window.opener)returns nullin IE 9.
alert(window.opener)null在 IE 9 中返回。

window.openeris a non-standard property and is not available in all browsers. It will also evaluate to nullif the window wasn't opened from another window, so it seems pretty unreliable.
window.opener是一个非标准属性，并非在所有浏览器中都可用。它还将评估null该窗口是否不是从另一个窗口打开的，因此它看起来非常不可靠。

I think I have got it now. Add an eventhandler in your parent window to your child's unload event.
我想我现在已经明白了。在您的父窗口中将一个事件处理程序添加到您孩子的卸载事件中。
var win = window.open("ChildPage.aspx");
function popUpUnLoaded() {
window.location = "ParentPage.aspx";
}
if (typeof win.attachEvent != "undefined") {
win.attachEvent("onunload", popUpUnLoaded );
} else if (typeof win.addEventListener != "undefined") {
win.addEventListener("unload", popUpUnLoaded, false);
}
This means that when the function below executes your parent page picks up on it.
这意味着当下面的函数执行时，您的父页面会接收它。
function ClosePopUp() {
self.close();
}
