vuejs2.0实现一个简单的分页

前端开发作者： 2024-08-20 20:05:01

用js实现的分页结果如图所示： css 模版 js 调用 new Vue({参数}) 就是创建了一个基本的组件,赋值给变量 pageBar.el就是element的缩写,定位模版的位置.data就是数

.page-bar{
    margin:40px;
}
ul,li{ 0px;
    padding: 0px;
}
li{
    list-style: none
}
.page-bar li:first-child>a {
   margin-left: 0px
}
.page-bar a{
    border: 1px solid #ddd;
    text-decoration: none;
    position: relative;
    float: left; 6px 12px;
    margin-left: -1px;
    line-height: 1.42857143;
    color: #337ab7;
    cursor: pointer
}
.page-bar a:hover{
    background-color: #eee;
}
.page-bar a.banclick{not-allowed;
}
.page-bar .active a{ #fff; default;
    border-color: #337ab7;
}
.page-bar i{
    font-style:normal; #d44950; 0px 4px;
    font-size: 12px;
}

<div class="page-bar">
    ul>
        li v-if="cur>1"><a v-on:click="cur--,pageClick()">上一页</a></li="cur==1"="banclick"v-for="index in indexs"  v-bind:class="{ 'active': cur == index}">
            ="btnClick(index)">{{ index }}="cur!=all"="cur++,1)">>下一页="cur == all">共i>{{all}}>页>
div>

var pageBar = new Vue({
    el: '.page-bar',data: {
        all: 20,//总页数
        cur: 1,1)">当前页码
});

computed: {
        indexs: function(){
          var left = 1;

          var ar = [];
          if(this.all>= 5){
            this.cur > 3 && this.cur < this.all-2){
                    left = this.cur - 2
                    right = this.cur + 2
            }else{
