<div id='root'>
<div v-if="numberArr.length == 0">{{showMessage}}</div>
<div class="container" v-for="(item, index) in getCurPageContent(numberArr, curPage, itemNumPerPage)" :key="index">
<div class="content">{{item}}</div>
<div class="pageButtonList">
<button class="leftBtn" @click="handleClick('leftBtn')"><</button>
<span class="pagination">{{curPage}}/{{totalPage}}</span>
<button class="rightBtn" @click="handleClick('rightBtn')">></button>
</div>
</div>
</div>
<script>
new Vue({
el: "#root",
data(){
return {
showMessage: 'No number',
content:'',
numberArr: [1, 2, 3, 4],
curPage: 1,
totalPage: 1,
itemNumPerPage: 1
}
},
mounted() {
this.init()
},
methods:{
init(){
this.totalPage = Math.ceil(this.numberArr.length / this.itemNumPerPage)
this.totalPage = this.totalPage < 1 ? 1 : this.totalPage
},
getCurPageContent: function(numberArr, curPage, itemNumPerPage){
return numberArr.filter(function(element, index){
if(index >= (curPage -1)* itemNumPerPage && index < curPage *itemNumPerPage){
return true
}else{
return false
}
})
},
handleClick: function(arg){
if(arg == 'leftBtn'){
this.curPage = this.curPage > 1 ? --this.curPage : this.totalPage
}else if (arg == 'rightBtn'){
this.curPage = this.curPage < this.totalPage ? ++this.curPage: 1
}
}
// handleLeftClick: function(){
// if(this.curPage > 1){
// this.curPage --
// }else{
// this.curPage = this.totalPage
// }
// },
// handleRightClick: function(){
// if(this.curPage < this.totalPage){
// this.curPage ++
// }else{
// this.curPage = 1
// }
// }
}
})
