ASP.NET跨域模态窗口（window.showModalDialog） - 总是参数值与QUOT;不确定＆QUOT; [英] ASP.NET cross domain modal window (window.showModalDialog) - parameter value always "undefined"

问题描述

我有两个网页，父页面的.aspx和子页面的.html。
在父页面我有JavaScript函数通过调用window.showModalDialog子页面模式窗口。

I have two webpages, parent page .aspx and child page .html. On parent page I have JavaScript function for invoking child page as modal window via window.showModalDialog.

function viewCourseModal(url) {

var sPars = SomeParameters();
var returnedValue = window.showModalDialog(url, "", sPars);
document.getElementById("modalReadyForTest").value = returnedValue;  

return returnedValue;

}

在子页面我有以下几点：

On the child page I have the following:

<script LANGUAGE="JavaScript">

function closewindow() {
    window.returnValue = "someValue";
    window.close();
}

<input id="Button1" type="button" value="Ready For Test" onclick="closewindow()" />

所以，当我启动父窗口并在点击按钮调用子模式窗口，参以someValue中被返回给父窗口（以modalReadyForTest控制）Button1的。

So when I launch parent window and invoke child modal window, parameter with "someValue" gets returned to the parent window (to modalReadyForTest control) upon clicking the button Button1.

当我在同一个域上的父母和孩子的页面，它工作正常。当我让他们在不同的领域，参数的值不会获得通过，而是它始终是不确定。

It works fine when I have both parent and child pages on the same domain. When I have them on different domains, value of the parameters does not get passed and instead it is always "undefined".

有什么办法有不同域的参数值返回到父页面模式窗口？可以将这些跨域问题都得到解决，或者我应该尝试完全不同的方法？

Is there any way to have modal window from different domain returning parameter value to parent page? Can those cross domain issues be solved at all or should I try completely different approach?

我会强烈AP preciate任何帮助。

I would highly appreciate any assistance.

谢谢，安瓦尔

推荐答案

父页：

<script>
function test(str) {
    alert(str);
}
</script>

子页面：

<input id="Button1" type="button" value="Ready For Test" onclick="opener.test('my value here')" />
