1、v-infinite-scroll="load" //load無限滾動加載的方法
 2、infinite-scroll-disabled //是否禁用無限滾動加載
 3、infinite-scroll-delay //節(jié)流時延，單位為ms
 4、infinite-scroll-distance //觸發(fā)加載的距離閾值，單位為px
 5、infinite-scroll-immediate //是否立即執(zhí)行加載方法，以防初始狀態(tài)下內(nèi)容無法撐滿容器。
 //默認(rèn)情況下，infinite-scroll-disabled是false，因此如果組件使用無限滾動加載組件，即使在vue不進(jìn)行加載方法的調(diào)用，組件也會調(diào)用該方法，因此如果需要控制的話，盡量是使用infinite-scroll-disabled屬性來進(jìn)行加載方法是否調(diào)用的控制。
