老師,有什么辦法進(jìn)來(lái)第一次后,這本書(shū)就加載完成了,下次進(jìn)就不需要在重新加載書(shū)了?這樣就可以直接渲染了 .(我就是想做第一次讀到哪里, 退出后再次進(jìn)入是在之前的地方開(kāi)始繼續(xù)閱讀, 現(xiàn)在我已經(jīng)在后退的時(shí)候把翻頁(yè)定位的數(shù)存了一下, 在進(jìn)入渲染這個(gè)數(shù), 但是渲染的時(shí)候就是重新加載, 書(shū)大了加載時(shí)間太長(zhǎng))...有什么辦法嗎? 請(qǐng)老師解答一下? 謝謝.

//下一頁(yè)
nextPage:?function(){
?vm.rendition.next().then(()?=>?{
?var?currentLocation?=?vm.rendition.currentLocation();
?var?progress?=?Math.floor(((vm.locations.percentageFromCfi(currentLocation.start.cfi)).toFixed(5))*10000)/100;
?//?console.log(progress);
?vm.progressN?=?progress;
?vm.onProgressInput(progress);
?})
},

//返回鍵
function?back(){
?localStorage.progressN?=?vm.progressN;
?window.history.back(-1);
}


vm.book.ready.then(()?=>?{
?vm.navigation?=?vm.book.navigation;
?return?vm.book.locations.generate();
}).then(result?=>?{
?vm.locations?=?vm.book.locations;
?console.log(vm.locations);
?vm.bookAvailable?=?true;
?var?progressOk?=?parseFloat(localStorage.progressN);
?var?pro?=?vm.locations.cfiFromPercentage(progressOk/100);
?//渲染電子書(shū)
?vm.rendition.display(pro);
?//?vm.onProgressInput(progressOk);
})
