<head>
<title>Users List</title>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha/css/bootstrap.css">

如何在使用 vue 组件时使此分页与 vue js 一起工作 请帮助我。
没那么复杂。您只是忘记 link 您的当前页面与您的组件。为此,只需更改 HTML 部分
中的代码
<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,去掉 VueComponent
中的 data
函数并添加分页属性
.....
props: {
pagination: {
type: Object,
required: true
}
},
computed: {
pagesNumber: function () {
if (!this.pagination.to) {
......
此外,从 VueComposent
中删除您的 getUsers
方法,并与 Vue
主实例
中的 getUsers
方法结合
getUsers: function(page){
this.$http.get('/user/api?page='+page).then((response) => {
this.$set('users', response.data.data);
this.$set('pagination', response.data);
});
