Disable survey if no javascript was created by jsansonn

Hi !

Is there a way to prevent completion of a survey / disable a survey if javascript is disabled on the user's computer?
Thanks for your help, regards,

A simple way, although not completely tamper proof, would be to hide the "Next" button with CSS and then show it with JavaScript.

This in template.css:

Code:

#movenextbtn,
#movesubmitbtn {
  display:none;
}

And this in template.js:

Code:

$(document).ready(function() {  
  $('#movenextbtn, #movesubmitbtn').show();
});

A more secure method would be to remove the {NAVIGATOR} placeholder from navigator.pstpl and insert the navigation buttons with JavaScript. Details of that script would vary by template and you would need to find a way to detect the last page so you could insert a "Submit" button instead of a "Next" button.

Think,
Maybe ,

Code:

<div id="navigatot-js"></div>
<script>
$(function() {
var navigator="{htmlentities(NAVIGATOR)}";
$(navigator).appendTo("#navigatot-js");
});
</script>

Shouldn't it be:

Code:

$(navigator).appendTo("#navigatot-js");

So "(navigator)" and not "(navigator}"?

If no, why not? (trying to update my JS skills...

Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
Always provide a LSS file (not LSQ or LSG).

No, I didn't test it.

I just tried to understand what was done and saw that bracket which confused me.

I am bit confused.
Shouldn't Limesurvey prevent entering surveys with disabled javascript on client side out of the box?
Or demand enabling Javascript to carry on?

No, I don't think so. Most basic question types will work without JavaScript although Expression Manager functionality will be impaired. I have several clients who insist that their surveys be fully accessible, even without JavaScript.

I would like to see a serverside only version of LS, but isn't LS 2.5 and LS 3.0 working without Javascript for respondents?
I am not sure the serverside checking is completely implemented. Wouldn't be surprised if more functionality has moved to the client.
I don't trust the client. Mobile devices haven't made it easier to convice me about moving code to the client.

If it's not : this clearly a bug and must be fixed.

Actually , since a lot of uear : there are a miscontrol on single choice item (we don't control single choice item at server part : did the item exoist).

But in general : EM does the job client side + server side.

It can be easily tested with deactivating JS.
