在速度模板中使用动态变量 [英] Using Dynamic Variables in Velocity Templates

问题描述

我正在使用速度模板来生成电子邮件模板，在这里我想为每个标签"创建表格，并将各自的值作为表格数据.

I am using velocity templates to generate email templates and here I want to create tables for each 'tag' with respective values as table data.

我正在传递一个包含标签详细信息的列表标签，包括 tagName，我使用它为每个标签传递相应的列表.(如果 tagName = "test"，我将测试表的数据作为 $test 传递)

I am passing a List tags with details of the tags including tagName, using which I am passing the respective List for each tag. (If tagName = "test", I am passing the data for the test table as $test)

如图所示，我已将每个表的数据设置为 $arrayobjs，但该表不显示行，因为我认为它不会遍历 $arrayobs.请帮我遍历数据并将数据设置到列中.

As shown I have set the data of each table to $arrayobjs, but the table does not display the rows as I think it doesnt iterate through the $arrayobs. Please help me iterate through the data and set the data to the coloumns.

P.S.-虽然我可以打印 $tags[0] 的值, $arrayobjs[0] 不打印值

P.S.-Although I am able to print the value of $tags[0] , $arrayobjs[0] does not print a value

    #set ($d = '$')                
        #foreach($tag in $tags)
        #set ($var = "${d}${tag.tagName}")
        #set ($arrayobjs = "#evaluate($var)")

推荐答案

在将近 2 年后，我建议以下答案:-)

After almost 2 years I suggest the following answer :-)

#set ($d = '$')
#set ($h = '#')

#foreach($tag in $tags)
    #set ( $temp = "${h}set ( ${d}var = ${d}${tag.tagName} )" )
    #evaluate($temp)

    ## html code for table header

    #foreach($o in $var)
        ## table rows
    #end
#end
