How do I use javascript to concatenate several responses into a single text string and assign it to a variable

Question

I need to take several text string responses and concatenate them into a single string and assign it to a variable.

Can this be done with Javascript?

Answer 1

You can do this by creating a free format hidden variable.

Here's a simple example where you can blend a string with a value of a question already captured within conditional IF statements ...

<input name="HdQ100_TEXT" type="hidden" value="
[%
Begin Unverified Perl

 my $Q100_text=0;
 
if (VALUE("HdX1_CODE")==1)
 {
  $Q100_text="accounting services &".(VALUE("Q50"));
 }

elsif (VALUE("HdX1_CODE")==2)
 {
  $Q100_text=(VALUE("Q50"));
 }

 return $Q100_text;
 
End Unverified
%]
">

hdx1_code and Q50 questions must appear at least one page-break earlier.

Thanks Paul and Bahadir.  Is there a way to do this with JavaScript rather than Perl?

A freeform question takes five inputs.  I want to take these five inputs and concatenate them into a single string so that: Q1+Q2+Q3+Q4+Q5 = Q6 alpha string.

Thanks.

Answer 2

In JavaSCript you use the plus symbole (+) to concatenate strings. So if you want to use JavaScript I would create Q6 as a free format hidden variable on the same page as Q1 through Q5 with value = "". Then, in custom JavaScript verification (so that it runs on page submit) you can put in something like

SSI_GetFormObject("Q6").value = SSI_GetValue("Q1") + SSI_GetValue("Q2") + SSI_GetValue("Q3") + SSI_GetValue("Q4") + SSI_GetValue("Q5");

the SSI_Get... functions were introduced in SSI Web 7 so if you are on an older version you can use

document.getElementById("questionName").value

to get and set form object values instead.
