               },
               afterPageChange: function (currentPage) {
               },
               beforeZoomChange: function (zoomPercentage) {
               },
               afterZoomChange: function (zoomPercentage) {
               }
           }
       });

i'm getting error in the following line  
gotoPage: true,
},
Please anyone can help me

推荐答案

只需删除后面的逗号（，）最后一个属性为visibleNavigationControls，visibleZoomControls和visibleFileOperationControls属性

Just remove the comma (,) after the last property attributes for visibleNavigationControls, visibleZoomControls and visibleFileOperationControls

gotoPage: true

zoomOut: true

print: false
