Javascript 如何在AngularJS中实现服务器端过滤和分页
我使用AngularJS来显示数据库中的数据,我在它上面实现了客户端分页和过滤,但当它加载大量数据时,我的应用程序崩溃了 所以,我想把它改为服务器端分页,将数据限制在每页10个项目,这样就完成了,但当我过滤数据时,只搜索页面上显示的项目。这是到目前为止我的代码Javascript 如何在AngularJS中实现服务器端过滤和分页,javascript,angularjs,pagination,filtering,server-side,Javascript,Angularjs,Pagination,Filtering,Server Side,我使用AngularJS来显示数据库中的数据,我在它上面实现了客户端分页和过滤,但当它加载大量数据时,我的应用程序崩溃了 所以,我想把它改为服务器端分页,将数据限制在每页10个项目,这样就完成了,但当我过滤数据时,只搜索页面上显示的项目。这是到目前为止我的代码 var app = angular.module('peradmin', ['ngRoute', 'ngAnimate']); var baseUrl = 'http://localhost/peradmin/'; var current

这是我的观点:
<div class="well" id="formsearch">
<form id="search-form" class="form-inline float-lg-right" action="" method="POST">
<input type="text" class="form-control" placeholder="Name" name="name" id="name" ng-model="filter.NAME" ng-change="filterData()">
<input type="text" class="form-control" placeholder="Email" name="email" id="email" ng-model="filter.EMAIL" ng-change="filterData()">
</form>
</div>
<div class="box">
<div class="box-body table-responsive" ng-controller="CustomerController">
<label>Page {{ currentPage + 1 }} from {{ pageNumber }} | Total: {{ totalData }} Data</label>
<br><br>
<table class="table table-hover table-bordered table-striped" width="100%">

<tr>
<th style="text-align:center;width:20%;">Email</th>
<th style="text-align:center;width:25%;">Name</th>

<tbody>
<tr ng-repeat="val in $parent.filtered = (customer | filter:{NAMA:filter.NAME,EMAIL:filter.EMAIL})">

</table>
<ul class="pagination" ng-if="totalData > 0">

<div class="alert alert-danger" ng-if="totalData == 0"><center>Data Is Not Found</center></div>

找不到数据
如何使其过滤到数据库上的整个数据
谢谢我想应该是:
$http({
method: 'POST',
url: baseUrl + 'customer/getcustomer',
data: {
limit: $scope.pageSize,
offset: currentPage,
filter: {
name: $scope.filter.NAME,
email: $scope.filter.EMAIL
}
},
headers: { 'Content-Type': 'application/json' }
})
然后在服务器端,使用这两个过滤器属性,您可以执行数据库端过滤
此外,您还需要在更改处理程序上应用过滤器或节流按钮:
$scope.filterData = function() {
$scope.currentPage = 0;
$scope.pageNumber = Math.ceil($scope.filtered.length / $scope.pageSize);
$scope.getCustomerData($scope.currentPage);
};
要执行油门,您可以尝试ng model options='{debounce:1000}'
:
<input type="text" ng-model-options='{ debounce: 1000 }' class="form-control" placeholder="Name" name="name" id="name" ng-model="filter.NAME" ng-change="filterData()">
<input type="text" ng-model-options='{ debounce: 1000 }' class="form-control" placeholder="Email" name="email" id="email" ng-model="filter.EMAIL" ng-change="filterData()">
我尝试了此操作,但出现了此错误ReferenceError:未在b.$scope.getCustomerData(CustomerController.js:17)中定义筛选器
抱歉,是的,请使用$scope进行尝试,像$scope.filter.NAME
仍然错误TypeError:无法读取b.$scope.getCustomerData的未定义属性“NAME”
我已经更新了上面的javascript代码,也许你可以找到原因…因为你需要声明$scope.filter。尝试以下操作:$scope.filter={NAME:,EMAIL:}
。将其放在$scope.currentPage=0之后代码>声明。很抱歉反应太晚,我已经仔细地尝试了你的代码,现在它正在工作……谢谢你,伙计,你是我的救星:你应该用谷歌搜索如何用你的服务器或数据库的语言实现分页,而不是角度。后端不应该关心什么是UI技术。我使用Codeigniter运行AngularJS,因为我是AngularJS的新手,所以它不完全是Javascript。
