Question

我正在尝试打开一个新窗口，并在struts 2的过程中调用一个动作。

问题是jsp打开但是直到我按下刷新或从新的jsp开始才动作。

我希望操作执行然后重定向到相应的jsp，但是现在它重定向到对应于第一个映射结果的jsp。

来自javascript的

动作调用：

function displayGraph(graphName)
        {   alert("displayGraph");
            var url = 'drawCMGraph?data=' + encodeURIComponent(graphName);
            alert(url);
            window.open(url, "_blank",
            "directories=no, status=no,width=550, height=200,top=0,left=0");
        }

struts.xml中

动作映射

<action name="drawCMGraph" class="com.casealerts.action.HomeAction" method="Drawgraph">
<result name="success">/casealerts/test.jsp</result>
<result name="error">/casealerts/Error.jsp</result>
        </action>

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <listener>  <!--This listener handles caching of data when the server context is loaded.-->
        <listener-class>CompListener</listener-class>
    </listener>
    <welcome-file-list>
        <welcome-file>/casealerts/Login.jsp</welcome-file>
    </welcome-file-list>
</web-app>

动作

package com.casealerts.action;

public class HomeAction extends ActionSupport implements ModelDriven<HomeForm>,Preparable,ServletRequestAware
{

    /**

    private static final long serialVersionUID = 272240572969090988L;
    Logger log=new Log4jHelper().getLogger(getClass());
    HomeDelegate hpd=null;
    private HttpServletRequest request;
    HomeForm form=null;
    private HttpSession session=null;

    @Override
    public void setServletRequest(HttpServletRequest request) {
        // TODO Auto-generated method stub
        this.request=request;

    }

    @Override
    public void prepare() throws Exception {
        // TODO Auto-generated method stub
        form=new HomeForm();

    }

    @Override
    public HomeForm getModel() {
        // TODO Auto-generated method stub
        return form;
    }

    public String Drawgraph()
    {
        session=request.getSession(true);
        hpd=new HomeDelegate(form,session);

        String result=hpd.getGraphData("alert", 1);

        return result;
    }
}

Answer 1

var url = 'drawCMGraph?data=' + encodeURIComponent(graphName);
            alert(url);

尝试将其更改为

var url = 'drawCMGraph.action?data=' + encodeURIComponent(graphName);
            alert(url);

Answer 2

我找到了解决问题的方法。似乎我们需要为动作类中的URL中发送的数据创建变量和getter以及setter。这适用于IE，但它在eclipse浏览器中不起作用

在javascript中从window.open（）调用时不调用Action方法
