Page，onload中请求成功获取值后，返回值：data.payload.bookInfo.pages

代码

pagesTMP = data.payload.bookInfo.pages;

pagesData = data.payload.bookInfo.pages;

if (pagesTMP) {

    if (pagesTMP.length > 5) {

        pagesTMP.forEach(function (val, index) {

            if (index >= pagesLimit) {

                pagesTMP[index].imgUrl = ‘’;

            }

        });

        that.setData({

            bookInfo: data.payload.bookInfo,

            pages: pagesTMP

        });

    } else {

        that.setData({

            bookInfo: data.payload.bookInfo,

            pages: pagesTMP

        });

    }

}

console.log(that.data.pages);

console.log(pagesData);‍

这里只修改了pagesTMP中的imgUrl，但是最终输出 pagesData 与 pagesTMP数值一样。
