我正在使用Laravel和VueJs，
我正在尝试以下操作：我创建了一个搜索栏，以按用户名，姓氏或电子邮件查找用户。
我曾经使用计算来编写过滤器，但我意识到我的过滤器仅对前10个元素进行过滤（因为我正在使用分页显示存储在数据库中的所有用户）
...我该怎么做才能使我的过滤器在我的所有用户上都能正常使用，而不是每十个给我一次分页服务（如果可以的话，请保持分页）？
这是我的脚本和模板（非常感谢）：
<script>
import UpdateProfile from './users/UpdateProfile';
import CreateUser from './users/CreateUser';
import User from '../models/user';
export default {
components: {UpdateProfile, CreateUser},
data() {
return {
showUpdateModal: false,
showCreateModal: false,
users: [],
user: new User(),
search:'',
paginator: {
current: 1,
total: 1,
limit: 10,
}
}
},
mounted() {
this.goToPage(1);
},
methods: {
userPermissions(user) {
return this.CONSTANTS.getUserType(user.permissions);
},
addUser(user) {
this.showCreateModal = false;
this.api.post('/users', user).then(() => {
this.goToPage(this.paginator.current);
});
},
editUser(user) {
this.user = JSON.parse(JSON.stringify(user));
this.showUpdateModal = true;
},
updateUser(user) {
this.showUpdateModal = false;
this.api.put('/users/' + user.id, user).then(() => {
this.goToPage(this.paginator.current)
});
},
deleteUser(user) {
this.api.delete('/users/' + user.id).then(() => {
this.goToPage(this.paginator.current)
});
},
navigatePrev(page) {
this.goToPage(page)
},
navigateNext(page) {
this.goToPage(page)
},
goToPage(page) {
this.api.get('/users?page=' + page + '&limit=' + this.paginator.limit).then(response => {
this.users = response.data;
this.paginator = response.paginator;
});
}
},
computed:{
filteredUsers: function () {
return this.users.filter((user) => {
var searchByName = user.name.toLowerCase().match(this.search.toLowerCase());
var searchByLastName = user.lastname.toLowerCase().match(this.search.toLowerCase());
var searchByEmail = user.email.toLowerCase().match(this.search.toLowerCase());
if(searchByName){
return searchByName;
}
if(searchByLastName){
return searchByLastName;
}
if(searchByEmail){
return searchByEmail;
}
});
}
}
}

答案 0 :(得分：1)
您可以在开始时就获取所有用户（如果不是太多数据），然后在客户端对它们进行分页。
类似的东西：
mounted() {
this.api.get('/users').then(response => {
this.users = response.data;
this.paginator.total = Math.ceil(this.users.length / this.paginator.limit);
});
},
methods: {
goToPage(page) {
this.paginator.current = page;
}
},
computed:{
filteredUsers: function () {
return this.users.filter((user) => {
var searchByName = user.name.toLowerCase().match(this.search.toLowerCase());
var searchByLastName = user.lastname.toLowerCase().match(this.search.toLowerCase());
var searchByEmail = user.email.toLowerCase().match(this.search.toLowerCase());
if(searchByName){
return searchByName;
}
if(searchByLastName){
return searchByLastName;
}
if(searchByEmail){
return searchByEmail;
}
}).filter((el, index) => {
return ( index >= (this.paginator.current - 1) * this.paginator.limit
&& index < this.paginator.current * this.paginator.limit);
});
}
}
}
更新
其他选择是在服务器端执行Serching并在每个页面请求中发送搜索字符串：
methods: {
goToPage(page) {
this.api.get('/users?page=' + page + '&limit=' + this.paginator.limit
+ '&search=' + this.search).then(response => {
this.users = response.data;
this.paginator = response.paginator;
});
},
performSearch() {
this.goToPage(1);
},
},
}
在模板中带有搜索块：
<!--Search Users-->
<div class="control is-expanded">
<h1>Search users</h1>
<input class="input" type="text"
v-model="search" placeholder="Find a user"
@change="performSearch"/>
</div>
您可以在输入或添加“搜索”后添加反跳以获得结果。搜索字段后面的按钮以触发performSearch()。
<!--Search Users-->
<div class="control is-expanded">
<h1>Search users</h1>
<input class="input" type="text"
v-model="search" placeholder="Find a user"/>
<button @click="performSearch">Search!</button>
</div>
