Question

我在sitefinity（w / MVC）中有2个页面，它们具有相同参数的不同控制器。一个页面返回一个包含搜索结果和所有表单元素的页面以进行搜索。

我希望第一个表单上的“打印”按钮将所有表单字段发送到不同的页面，其中不同的控制器/组件具有相同的参数。

（我在Sitefinity的论坛上发布了相同的问题，但尚未收到回复。我也一直在搜索，但没有找到类似的结果）

在ASP.Net或Actual MVC中，这很容易在MVC中，我能够这样做：

            var d = document;
            var f = d.forms[0];
            window.open('', 'B2BDownload', 'width=900,height=800,resizable,scrollbars;');
            var pt = f.target;
            var pm = f.action;
            f.action = '/UtilityPages/DownloadInvoices';
            f.target = 'B2BDownload';
            f.submit();
            f.action = pm;
            f.target = pt;

但在Sitefinity的MVC中，相同的代码会产生此错误:(在正确的页面上）

Server Error in '/' Application.

Answer 1

这是因为页面包含视图状态，并且视图状态只能由生成它的页面进行解密。目标页面正在尝试解密此字段，但它不能并且正在抛出异常。

在调用submit（）之前，尝试在DOM中搜索名为“__VIEWSTATE”的隐藏表单字段，并将其值设置为空字符串（“”）。这将导致目标页面不尝试加载视图状态。
