访问另一个jsp中搜索容器中显示的值 [英] Access values displayed in Search Container in another jsp

问题描述

我有一个jsp，其中显示了一些有人说员工的数据. 每个员工的数据显示为一行. 我已将每一行都做为链接，以便当用户单击任何提供特定员工详细信息的行时， 用户将被定向到一个显示员工相同数据的jsp，以便可以进行进一步处理.

我的问题是，当用户单击包含特定员工信息的行时，我应该如何传递该员工的数据?

我现在要做的是:

 <portlet:renderURL  var="viewPendingLeaveApplicationsURL"/>

<liferay-ui:search-container delta="20" emptyResultsMessage="No Results Found">
    <liferay-ui:search-container-results total="<%= pendingApprovals .size() %>"
            results="<%= ListUtil.subList(pendingApprovals , searchContainer.getStart(), searchContainer.getEnd()) %>" />

    <liferay-ui:search-container-row keyProperty = "empId" modelVar="search"
            className="com.corpserver.mallyas.mis.portal.model.LeaveApplication">

        <portlet:renderURL var="leaveApplicationURL">
            <portlet:param name="jspPage"  value="/admin/AddCompany.jsp" />
            <portlet:param name="search" value='<%String.valueOf(search.getEmpId());%>'/>
        </portlet:renderURL>

        <liferay-ui:search-container-column-text name='Leave Duration' value='<%=String.valueOf(search.getLeaveDuration())%>' href="<%= leaveApplicationURL.toString()%>" />

        <liferay-ui:search-container-column-text name="From" value='<%=String.valueOf(search.getLeaveFromDate())%>' href="<%= leaveApplicationURL.toString()%>"/> 

        <liferay-ui:search-container-column-text name="To" value='<%=String.valueOf(search.getLeaveToDate())%>' href="<%= leaveApplicationURL.toString()%>"/> 

        <liferay-ui:search-container-column-text name="Reason" value='<%=String.valueOf(search.getLeaveReason())%>' href="<%= leaveApplicationURL.toString()%>"/> 

        <liferay-ui:search-container-column-text name="Remarks" value='<%=String.valueOf(search.getLeaveRemarks())%>' href="<%= leaveApplicationURL.toString()%>"/> 

    </liferay-ui:search-container-row>

    <liferay-ui:search-iterator/>

</liferay-ui:search-container>
 

在上面的代码中，我试图传递用户选择的行的empId. 但是第二个jsp中什么也没有显示.我想在第二个jsp上传递所有这些信息.

解决方案

我在代码中看到一个小问题，问题在于生成URL的方式:

<portlet:renderURL var="leaveApplicationURL">
    <portlet:param name="jspPage"  value="/admin/AddCompany.jsp" />
    <portlet:param name="search" value='<%String.valueOf(search.getEmpId());%>'/>
</portlet:renderURL>

此行:

<portlet:param name="search" value='<%String.valueOf(search.getEmpId());%>'/>

应为:

<portlet:param name="search" value='<%= String.valueOf(search.getEmpId()) %>'/>

您是否注意到了这一点: <%= String.valueOf(search.getEmpId())%>，所以像<%=这样添加了开头，而尾随的;也被删除了.

因此，简而言之，您需要使用 jsp expression 在value属性中的脚本代码块中. >

I have a jsp where I display some data of some people say employees. The data of each employee is displayed as a row. I have made each row as a link so that when a user clicks on any row which gives details of a particular employee, the user is directed to a jsp which displays the same data of the employee so that further processing could be done.

My question is how should I pass the data of an employee when a user clicks on the row which contains that particular employee information?

What I have right now done is this:

<portlet:renderURL  var="viewPendingLeaveApplicationsURL"/>

<liferay-ui:search-container delta="20" emptyResultsMessage="No Results Found">
    <liferay-ui:search-container-results total="<%= pendingApprovals .size() %>"
            results="<%= ListUtil.subList(pendingApprovals , searchContainer.getStart(), searchContainer.getEnd()) %>" />

    <liferay-ui:search-container-row keyProperty = "empId" modelVar="search"
            className="com.corpserver.mallyas.mis.portal.model.LeaveApplication">

        <portlet:renderURL var="leaveApplicationURL">
            <portlet:param name="jspPage"  value="/admin/AddCompany.jsp" />
            <portlet:param name="search" value='<%String.valueOf(search.getEmpId());%>'/>
        </portlet:renderURL>

        <liferay-ui:search-container-column-text name='Leave Duration' value='<%=String.valueOf(search.getLeaveDuration())%>' href="<%= leaveApplicationURL.toString()%>" />

        <liferay-ui:search-container-column-text name="From" value='<%=String.valueOf(search.getLeaveFromDate())%>' href="<%= leaveApplicationURL.toString()%>"/> 

        <liferay-ui:search-container-column-text name="To" value='<%=String.valueOf(search.getLeaveToDate())%>' href="<%= leaveApplicationURL.toString()%>"/> 

        <liferay-ui:search-container-column-text name="Reason" value='<%=String.valueOf(search.getLeaveReason())%>' href="<%= leaveApplicationURL.toString()%>"/> 

        <liferay-ui:search-container-column-text name="Remarks" value='<%=String.valueOf(search.getLeaveRemarks())%>' href="<%= leaveApplicationURL.toString()%>"/> 

    </liferay-ui:search-container-row>

    <liferay-ui:search-iterator/>

</liferay-ui:search-container>

In the above code I am trying to pass the empId of the row which the user selects. But nothing gets displayed in the second jsp. I want to pass all of this information on second jsp.

解决方案

Well I see a small problem in the code, problem is in the way the URL is generated:

<portlet:renderURL var="leaveApplicationURL">
    <portlet:param name="jspPage"  value="/admin/AddCompany.jsp" />
    <portlet:param name="search" value='<%String.valueOf(search.getEmpId());%>'/>
</portlet:renderURL>

This line:

<portlet:param name="search" value='<%String.valueOf(search.getEmpId());%>'/>

should be:

<portlet:param name="search" value='<%= String.valueOf(search.getEmpId()) %>'/>

did you notice this: <%=String.valueOf(search.getEmpId())%>, the starting is added like <%= and the trailing ; is removed.

So in short you need an jsp expression instead of scriptlet code block in the value attribute.
