<html>
<head>
	<title>Users List</title>

          '<ul class="pagination">' +
              '<li v-if="pagination.current_page > 1">' +
                  '<a href="#" aria-label="Previous" @click.prevent="changePage(pagination.current_page - 1)">' +
                      '<span aria-hidden="true">«</span>' +

如何在使用vue组件时使用vue js进行此分页请帮助我。

Answer 1

这并不复杂。您只是忘了将当前页面与组件链接。为此，只需在HTML部分中更改代码

即可

<vue-pagination></vue-pagination>

到

<vue-pagination  :pagination="pagination" v-on:click="getUsers(pagination.current_page)"></vue-pagination>

在你的js代码中，从data中删除VueComponent函数并添加分页道具

.....
props: {
        pagination: {
            type: Object,
            required: true
        }
    },
computed: {
    pagesNumber: function () {
        if (!this.pagination.to) {
......

另外，从getUsers移除VueComposent方法，并与getUsers主要实例中的Vue方法结合使用

getUsers: function(page){
  this.$http.get('/user/api?page='+page).then((response) => {
     this.$set('users', response.data.data);
     this.$set('pagination', response.data);
  });

我认为，现在您的代码应该按预期工作。
