jQuery同位素RTL

我正在使用此代码在具有RTL支持的情况下运行Isotope

$.Isotope.prototype._positionAbs = function( x, y ) {
  return { right: x, top: y };
};

$('.portfolio-isotope').each(function() {
    var layoutMode = $(this).attr('data-layoutmode');
    if(!layoutMode || layoutMode === ""){
        layoutMode = 'fitRows';
    }

    $(this).isotope({
        transformsEnabled: false,
        itemSelector: '.portfolio-element',
        layoutMode : layoutMode,
        transitionDuration : '0.8s'
    });

});

由于某种原因，我让浏览器返回JavaScript错误

Uncaught TypeError: Cannot read property 'prototype' of undefined

可能是什么原因呢？

最佳答案

只是
使用这个选项
isOriginLeft:否

和CSS

.isotope .isotope-item
{
  -webkit-transition-property: right, top, -webkit-transform, opacity;
     -moz-transition-property: right, top, -moz-transform, opacity;
      -ms-transition-property: right, top, -ms-transform, opacity;
       -o-transition-property: right, top, -o-transform, opacity;
          transition-property: right, top, transform, opacity;
}
