Adding animation when changing question divs from display:none to display:block?

Hi all, I've just started using LimeSurvey and I'm amazed at all it can do.

I've been doing some customizing on the visual side of things and there's one point I'm stuck at.

Several of the questions in my survey are conditionalized so they only appear if the question before them is answered in a certain way. From the code I can see that this is done by changing the css property display:none to display:block. I'd like to change this so they use the jquery slideDown/slideUp animations, something like:

function showDiv(divId) {
$("#" + divId).slideDown(250);
}
function hideDiv(divId) {
$("#" + divId).slideUp(250);
}

I assume this is done with the "checkconditionals" onclick function, but I can't figure out how to change it. Can someone point me in the right direction, or am I creating more work than what it's worth?

The JavaScript that dynamically shows or hides questions is generated by the core file classes/expressions/LimeExpressionManager.php. Search for "show()" in that file.

Thanks for the response. I don't have a classes folder, and a search for LimeExpressionManager.php came up empty. I'm using v2.00+. Where else should I look?

Maybe it can be great if EM use a:
.lsHide() / lsShow fnction to be easyly replaced by own scripting.

And put an handler at end of this function too :).

For 2.1 i think.

Thanks for your help! I got this to work.

I agree a custom function would be a nice addition for future versions.

For my own reference (esp. after upgrades), and anyone else interested, I got this to do what I wanted by doing the following:

In
application/helpers/expressions/em_manager_helper.php

changed line 6488:
$relParts[] = " $('#question" . $arg . "').show();\n";
to
$relParts[] = " $('#question" . $arg . "').slideDown();\n";

changed line 6521:
$relParts[] = " $('#question" . $arg . "').hide();\n";
to
$relParts[] = " $('#question" . $arg . "').slideUp();\n";

It would be nice to have a survey setting to have conditional questions either pop-up directly or slide in. Shouldn't be too hard to implement, maybe a good idea for Google Code-in!?

No, best is to have a jquery extension like lsHide, lsShow, the user ca do what thez want in lsHide/lsShow.
For exaple you can change the opacity, pur a visibility:hidden etc ... (in template.js).


If you put an option, it's hard to add an different option. And the option we choose are not good for whole peaople.

Less than 30 minute of work ...

Hello,

You don't have to change LS core to do this. You can do it in your template.

Add this at your template.js file:
(function($){
	$.fn.hide = function(){
	    $(this).slideUp('slow');
	    $(this).css('display','none');
	};
	$.fn.show = function(){
	    $(this).slideDown('slow', function() {
	    if($(this).is('tbody')){
	        $(this).css('display','table-row-group');
	   }else{
	        $(this).css('display','block');
	   }
    });
 
	};
})(jQuery)
