極簡vue分頁組件

組件代碼：
<template>
<div class="pagination">

<div class="left">
  <div
    :class="{'disable': currentPage == 1}"
    class="btn pre"
    @click="currentPage > 1 ?currentPage --: 1"
  ></div>
  <span>第</span>
  <input class="current" v-model="currentPage" type="text">
  <span>頁</span>
  <div
    :class="{'disable': currentPage == pageCount}"
    class="btn next"
    @click="currentPage < pageCount ? currentPage ++: pageCount"
  ></div>
  <span class="pageCount">共{{pageCount}}頁</span>
</div>
<div class="right">顯示第{{startIndex}}到{{enIndex}}個記錄，共{{total}}個記錄</div>

</div>
</template>
<script>
export default {
data() {

return {
  currentPage: this.currentPage
};

},
watch: {

currentPage(value) {
  this.$emit("pageChange", value);
}

},
computed: {

pageCount() {
  return Math.ceil(this.total / this.pageSize);
},
startIndex() {
  return (this.currentPage - 1) * this.pageSize + 1;
},
enIndex() {
  if (this.currentPage * this.pageSize >= this.total) {
    return this.total;
  } else {
    return this.currentPage * this.pageSize;
  }
}

},
props: {

currentPage: {
  type: [Number, String],
  default: 1
},
pageSize: {
  type: [Number, String],
  default: 10
},
total: [Number, String]

}
};
</script>
