Question

Hi everyone!

 

I have an HTML block, where I want to display parameters like follows:

 

Author: [@field:author], Coauthor:[@field:coauthor]

 

But the [@field:coauthor] parameter is empty often.

 

Is it possible to display the ", Coauthor:[@field:coauthor]" part only if a coauthor is exist?

 

Thank you for your time!

Hello Cameron,

 

If I understand correctly, you can use a JavaScript code.

Please select your "HTML Block", click the "Source" button, delete the current text and enter the following code:

Author: [@field:author]
<script language="javascript">
var coauthor='[@field:coauthor]';
if (coauthor.length>0)
{
coauthor = ", Coauthor: "+coauthor;
document.write(coauthor);
}
</script>

Also I would recommend you to disable AJAX on the DataPage.

You can open the "Results Page Options" step and uncheck the "Enable AJAX" checkbox.

 

I hope, it helps.

Hello! 

Just to update, if [@field:coauthor] is blank, there's another way to hide Coauthor. You can also use SQL Formula instead of script.

In Submission Form/ Details, you can add virtual field and use Calculated Value as Form Element. 

CASE WHEN [@field:coauthor] ='' THEN '' ELSE 'Coauthor:[@field:coauthor]' END

 

Then, you can display the result of this Virtual field in the HTML Block. 

 

Hope this helps!
