A couple of things...

1) You cannot access Expression Manager variables from template.js - they are only available in the survey. Try this to access the SID:

Code:

  // Find the survey and group IDs
  if($( 'input#fieldnames' ).length != 0) {
    var fieldNames = $('input#fieldnames').attr('value');
    var tmp = fieldNames.split('X');
    var sID = tmp[0];
    var gID = tmp[1];
  }

2) Using the triple-equals sign searches for an exact comparison, including variable type, and since you have enclosed {SID} in quotes, it will be a string and then you try to compare it to a number in your IF() statement. Try this (given the var from above):

Code:

if (sID == 111111){

Hi,

thanks so much @tpartner!

I tried to get the SID with the given code, but it did not return the SID, since console.log($('input#fieldnames' ).length); . returns 0, i.e. there are no fieldnames on the page where participants can enter their token. Right?

Code:

$( document ).ready( function() {
  // Find the survey and group IDs
  if($( 'input#fieldnames' ).length != 0) {
    var fieldNames = $('input#fieldnames').attr('value');
    var tmp = fieldNames.split('X');
    var sID = tmp[0];
    var gID = tmp[1];
  }
 
  // But: this does not work on this page, because ...
  console.log($('input#fieldnames' ).length);  // ... returns 0, i.e. there are no fieldnames on the page where participants can enter their token. Right?
});

But that brought me to the idea to extract the SID from the URL - unfortunately it's hardcoded, but it works in my case: I get the survey specific token messages I wanted.

Code:

$(document).ready(function(){
 
  /* Extract SID from URL */
  var pathname = window.location.pathname; /* Get the pathname from the URL */
  var pathArray = window.location.pathname.split( '/' );
  var sID = pathArray[3]; /* in my case (LSdirectory/index.php/111111/newtest/Y#) the SID sits at position 3 */
  console.log(sID);  /* returns the SID extracted from the URL */
 
  if (sID == 111111){
 
    if (typeof tokenlabel === "undefined"){
        tokenlabel ="1 YOUR TOKEN LABEL : ";
    }
 
    if (typeof tokentext === "undefined"){
        tokentext ="1 YOUR TOKEN TEXT DESCRIPTION {SID}";
    }
 
    if (typeof tokenerror === "undefined"){
        tokenerror ="1 <br><br><strong class='error'>YOUR ERROR MESSAGE.</strong>";
    }
  }
 
  if (sID != 111111){
 
    document.getElementById("token").style.display="none";  /* hides the tokenform */
 
    if (typeof tokenlabel === "undefined"){
        tokenlabel ="2 YOUR TOKEN LABEL : ";
    }
 
    if (typeof tokentext === "undefined"){
        tokentext ="2 YOUR TOKEN TEXT DESCRIPTION {SID}";
    }
 
    if (typeof tokenerror === "undefined"){
        tokenerror ="2 <br><br><strong class='error'>YOUR ERROR MESSAGE.</strong>";
    }
 
  }
 
   if ($("#tokenform").length )
   {
        $("#tokenmessage").html(tokentext);
        $("label[for='token']").text(tokenlabel);
   }
   else
   {
       $("#tokenmessage").html(tokentext+tokenerror);
   }
 
})

Also thanks a lot for your hint with the "===" exact comparison - it's decisive in this case - thanks a lot!

Is the upper code "OK"? Or is there something I should avoid? (probably hardcoding :-)

Thanks and all the best,
G

Oh, yeah, sorry I forgot that you weren't in the survey yet so there is no fieldnames input.

Parsing the URL works but you could get the sID from the action attribute of the form:

Code:

var sID = $('#limesurvey').attr('action').split('sid=')[1];

Regarding your code, it may be slightly more efficient to use an ELSE statement instead of two IFs when testing for the sID.

In version 2.6.7LTS I see

Code:

</script><form id="tokenform" autocomplete="off" action="/fragen/index.php/111111" method="post">

If that's correct I simply stay with the extraction from the URL.

I replace the second

Code:

if (sID != 111111){

by

Code:

else {

which works! Thanks again!

Best,
G

Hi,

Just for the record: I found another solution to get the sid which is a little less hardcoded (it does not fix the position, at least). I had to look for such a solution since I just ran into an error caused by this ;-)

Best, G

Code:

$(document).ready(function(){
 
  /* Extract SID from URL */
  var pathname = window.location.pathname; /* Get the pathname from the URL */
  var pathArrayStep1 = window.location.pathname.split( 'sid/' )[1];  /* Split the pathname in two (at the sid) and get the second (=1) element of the array */
  var sID = pathArrayStep1.split( '/' )[0];  /* Split the pathname at the "/" and get the first (=0) element of the array */
  console.log(sID);  /* returns the SID extracted from the URL */
 
 
  if (sID == 111111){
 
    if (typeof tokenlabel === "undefined"){
        tokenlabel ="1 YOUR TOKEN LABEL : ";
    }
 
    if (typeof tokentext === "undefined"){
        tokentext ="1 YOUR TOKEN TEXT DESCRIPTION {SID}";
    }
 
    if (typeof tokenerror === "undefined"){
        tokenerror ="1 <br><br><strong class='error'>YOUR ERROR MESSAGE.</strong>";
    }
  }
 
  if (sID != 111111){
 
    document.getElementById("token").style.display="none";  /* hides the tokenform */
 
    if (typeof tokenlabel === "undefined"){
        tokenlabel ="2 YOUR TOKEN LABEL : ";
    }
 
    if (typeof tokentext === "undefined"){
        tokentext ="2 YOUR TOKEN TEXT DESCRIPTION {SID}";
    }
 
    if (typeof tokenerror === "undefined"){
        tokenerror ="2 <br><br><strong class='error'>YOUR ERROR MESSAGE.</strong>";
    }
 
  }
 
   if ($("#tokenform").length )
   {
        $("#tokenmessage").html(tokentext);
        $("label[for='token']").text(tokenlabel);
   }
   else
   {
       $("#tokenmessage").html(tokentext+tokenerror);
   }
 
})
