我有一个 jsp 页面（page1.jsp）。此页面有一个网格，使用说动作类 A 加载网格，在其中一个网格列上我有一个 onclick 打开一个对话框。打开的对话框调用不同的struts 动作类，比如B。这个动作类有一个结果页面page2.jsp。这个页面也有一个网格。我遇到的问题是数据以 JSON 格式而不是在网格上显示。

我不确定 struts.xml 是否有问题或问题出在哪里。我检查了 firebug 中的 JSON 数据，一切看起来都正确，gridModel 具有预期的数据，但数据未显示在网格上，它在模式对话框中显示为 JSON 数据。

使用：Struts 2.2.3，Struts-jquery-plugin 版本 3.3.1

您需要执行 2 个操作：

<action name="DisplayAction" class="com.ads.snf.trelang.action.ClassA" method="{1}">
    <result name="input">/blah/page1.jsp</result>
    <result name="success">/blah/page1.jsp</result></action>

<action name="JsonAction" class="com.ads.snf.trelang.action.ClassA" method="{1}">
    <result type="json"></result></action>

当你传递像gridModel这样的结果参数时，最好的方法是使用root。

网格模型

但是如果你设置 gridModel="gridModel" 不需要指定参数，struts 会读取你的 json 并找到 gridModel 列表没有问题。

如果您需要有关 Struts2-jquery 的更多信息，我邀请您在以下位置发帖：https ://groups.google.com/forum/?hl=fr&fromgroups#!forum/struts2-jquery

Johannes 将回答您和其他 struts2-jquery 用户的任何问题。我希望这会起作用，因为我没有查看所有代码，但似乎很好。
