window.opener正在重用null [英] window.opener is returing null
问题描述
我在www.abc.com中有一个链接，单击该链接会打开www.def.com中的弹出窗口.
www.def.com的弹出窗口中有一个表单.单击表单上的保存"按钮后，我希望关闭当前窗口
并且父级应重定向到某个位置.
I have a link in www.abc.com , clicking on which it opens up a popup from www.def.com .
There is a form in that popup from www.def.com. After clicking upon the "Save" button on the form I want the current window to be closed
and the parent will should redirect to a location.
在进行此更改之前，当我从www.abc.com显示表单时，以下代码可以正常工作.
Before this change when I was showing the form from www.abc.com, the below code was working fine .
<script language="JavaScript">
parent.window.close();
parent.opener.parent.window[1].location.replace('/abc.jsp?custid=12345');
</script>
但是现在"parent.opener" is returning null.因此，我能够关闭弹出窗口，但无法将父窗口重定向到
地理位置.
But now "parent.opener" is returning null. So I am able to close the popup but not able to redirect the parent window to
disired location.
我知道我要问的是有线的，但这是必需的.
I know what I am asking is bit wired, But this the requirement.
推荐答案
在"abc.moc"处
At "abc.moc"
<!DOCTYPE html>
<html>
<head>
<script>
// open `popup`
var popup = window.open("popup.html", "popup", "width=200,height=200");
// handler `message` event from `popup.html`
function receiveMessage(event) {
console.log(event, event.data);
this.location.href = event.data;
}
window.addEventListener("message", receiveMessage, false);
</script>
</head>
<body>
</body>
</html>
位于"def.moc"处
at "def.moc"
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form>
<input type="button" value="Save">
</form>
<script>
console.log(window.opener);
var button = document.querySelector("form input[type=button]");
button.onclick = function(e) {
e.preventDefault();
e.stopPropagation();
// do stuff with `form`
// call `.postMessage()` on `window.opener` with
// first parameter URL to redirect `abc.moc`,
// second parameter `location.href` of `abc.moc`
window.opener.postMessage("redirect.html",
window.opener.location.href);
// close `popup`
window.close();
}
</script>
</body>
</html>
