Hide Next button in n seconds

Challenge

In order to not allow respondent click on the Next button in a period of time

As a questionnaire creator

I want to hide the Next button in some seconds 

Example

Solution

• In questionnaire template editor, choose the question I want to hide the Next button and then go to the Properties - Edit question properties - Language dependent - Select javascript property
• Override quest.onInit function.
• In that function, check if the Next button exists.
• If it doesn't exist, do nothing, else disable the Next button, set the time out to number of seconds I want to hide the button, then show the button again.

Code

quest.onInit = function()
{
	var secsTimeout = 10;
	if ( !document.getElementsByName('next') || document.getElementsByName('next').length == 0 ) 
		// next button not available
		return;
	document.getElementsByName('next')[0].style.display='none';
	setTimeout("document.getElementsByName('next')[0].style.display='';", secsTimeout*1000);
}
