FreeMarker Help! (Looping Through 2 Lists)

Hey Everyone,

 

Was going to see if anyone could help me out with a problem I'm trying to solve. Basically in a nutshell, I have 2 lists that I am iterating through, and I am trying to match index values of the items in each list up. So for example:

 

property1 = Bill, Steve

property2 = Gates, Jobs

 

And my code looks as follows:

 

 

<#if  (property1')?exists &&  (property2')?exists)>
     <#list JiveGlobals.getJiveProperty('property1')?split(",") as metaNAME>
          <#list JiveGlobals.getJiveProperty('property2')?split("-") as metaVALUE>
               <meta name="${metaNAME}" content="${metaVALUE}">
          </#list>
     </#list>
</#if>

 

 

This code prints out:

 

 

<meta name="Bill" content="Gates">     
<meta name="Bill" content="Jobs">     
<meta name=" Steve" content="Gates">     
<meta name=" Steve" content="Jobs">

 

 

 

 

But I want them to only print out the same index values, so the output I WANT is:

 

 

<meta name="Bill" content="Gates">
<meta name=" Steve" content="Jobs">

 

 

 

I've been wracking my brain trying to figure out how I can do this, if anyone can offer any advice / help, I would GREATLY appreciate it!

 

Thanks in advance!!

Re: FreeMarker Help! (Looping Through 2 Lists)

Hello,

 

I did a little checking on freemarker, and from what I found, you want to have:

<#if  (property1')?exists &&  (property2')?exists)>

      <#list JiveGlobals.getJiveProperty('property1')?split(",") as metaNAME>
            <meta name="${metaNAME}" content="${property2[metaNAME_index]}"> 
      </#list>
 </#if>

The reason you were getting that output is that you were nesting a loop inside another, so for every iteration of the outer loop you ran through the entire inner loop.  This way, you'll only run through the outer loop, and since you index the last-name-list with your loop variable, your last names will stay in sequence with your first names.  Hope that helps.

 

Thanks,

Kevin

Re: FreeMarker Help! (Looping Through 2 Lists)

Thanks Kevin for the quick response!

 

I know why that's my problem, but I don't know much about freemarker to be able to control my output. I'm pretty sure there isn't a clean way to do any indexing or a .length function like Java. So that's why I posted up if anyone could help me out.

 

If anyone has any ideas, I would be forever grateful! =)

 

Thanks!
