cuijian-dexter commented on issue #8793: 图例名字过长，使用翻页滚动会导致按钮点击无效 URL: https://github.com/apache/incubator-echarts/issues/8793#issuecomment-410168098 @Ovilia 这个地方源码确实不太好看，_pageGo这个函数，我不知道为什么每次翻页的时候都要走两遍。。还没有进行仔细研读。目前先解决的办法是把_pageGo函数内容改成如下： var scrollData = this._getPageInfo(legendModel); if(scrollData.pagePrevDataIndex === scrollData.pageNextDataIndex) { if (to === 'pagePrevDataIndex') { scrollData.pagePrevDataIndex --; }else{ scrollData.pageNextDataIndex ++; } } var scrollDataIndex = scrollData[to]; scrollDataIndex != null && api.dispatchAction({ type: 'legendScroll', scrollDataIndex: scrollDataIndex, legendId: legendModel.id }); 在翻页的时候，如果两个相同的话，就移一个。暂时可以保证可以分页，但不能完全解决问题。
