vue 实现分页组件

类似于element分页（缩减版）， 废话不多说，直接上代码

组件vue代码

var Pagination={
            template:`<div class="main">
                <div>共{{total}}条</div>
                <button class="first" @click="First" v-bind:disabled="a">{{first}}</button>
                <button class="prev" @click="Prev" :disabled="b">{{prev}}</button>
                <ul>
                    <li v-for="item in list" @click="buttonPage(item)" :class="{active:currentPage==item}">{{item}}</li>
                </ul>
                <button class="next" @click="Next" :disabled="c">{{next}}</button>
                <button class="last" @click="Last" :disabled="d">{{last}}</button>
                <input :value="value" @input="change" />
                <button  @click="just">跳转</button>
            </div>`,

                    this.$emit("currentPage",val)
                    //ajax请求数据
                }
                
            }
        }

样式代码

.main{
                 100vw;
                height: 50px;
                display: flex;
                align-items: center;
            }
            .main input{
                outline: none;
                padding: 0;
                margin: 0;
                border: 0;
                 40px;
                text-align: center;
                padding: 6px 10px;
                margin-left: 10px;
                border: 1px solid #2AC845;
            }
            .main button{
                padding: 5px 10px;
                border: 1px solid #2AC845;
                margin: 0 5px;
                background-color: #FFFFFF;
            }
            ul{
                margin: 0;
                padding: 0;
                display: flex;
            }
            li{
                list-style: none;
                padding: 3px 15px;
                border: 1px solid #2AC845;
                margin: 0 5px;
                margin: 0 5px;
            }
            .active{
                background-color: #2AC845;
                color: #FFFFFF;
            }

效果图如下：

使用方法：在父组件中模板中引入       <Pagination :config="pageConfig" @currentPage="handCurrenPage"></Pagination>

pageConfig:{
　　total:35,
　　pageSize:7,
}

handCurrenPage(val){
　　console.log(val)
}

total是获取的总数，pageSize是每页要显示的条数，handCurrenPage是获取页面的方 val=== 点击的页数

在页面created中调取接口拿到第一页数据，其他接口则放在handCurrenPage中获取其它页数据。
