[SOLVED] Jquery panzoom duration

Jquery panzoom duration

Has anyone been able to get the duration on the panzoom to function? https://github.com/timmywil/jquery.panzoom

I went into the source code and increased the duration time from 200 to 1200 and did not see a change when I called the zoom.

 $panzoom.panzoom("zoom", 2.5);

updated

         var $section = $('section').first();
         $panzoom =  $section.find('.panzoom').panzoom({
            contain: false,
            minScale: 1,
            maxScale: 3,
            contain: true,  
            duration:1200
          }).panzoom('zoom', true);


$(elm).on('click' function(){

 $panzoom.panzoom("zoom", true);
});

Solution

Why not just change it with the option() method? From the panzoom docs:

// One at a time
// Sets the scale increment option
$elem.panzoom("option", "duration", 1200);

// Several options at once
$elem.panzoom("option", {
  increment: 0.4,
  minScale: 0.1,
  maxScale: 2,
  duration: 500,
  $reset: $("a.reset-panzoom, button.reset-panzoom")
});

You shouldn't have to change any defaults in the source to set a different duration.

EDIT:

You need to give "zoom" a boolean attribute of true to set your own duration in options, as mentioned in the docs:

"If the method is passed a boolean, true will indicate to perform a zoom-out based on the increment specified in options. If false (or omitted), a zoom-in will be performed."

Below is a working version where i've set a custom duration in options (2500) and used the panzoom("zoom", true):
