我有ng-table页面,可以正常使用初始数据.我有一个选择框,根据选择的选项发送服务器请求,然后我将新数据转换为角度但不更新ng-table.
这是我的观点:
<section data-ng-controller="ReportsController"> <div class="plain-Box"> <table ng-table="tableParams" show-filter="true" class="table table-striped"> <thead> <tr> <th ng-repeat="column in columns" ng-show="column.visible" class="text-center sortable" ng-class="{ 'sort-asc': tableParams.isSortBy(column.field,'asc'),'sort-desc': tableParams.isSortBy(column.field,'desc') }" ng-click="tableParams.sorting(column.field,tableParams.isSortBy(column.field,'asc') ? 'desc' : 'asc')"> {{column.title}} </th> </tr> </thead> <tbody> <tr ng-repeat="user in $data"> <td ng-repeat="column in columns" sortable="column.field"> {{user[column.field]}} </td> </tr> </tbody> </table> </div>
我的控制器:
angular.module('reports').controller('ReportsController',['$scope','$stateParams','$location','Authentication','Reports','$filter','ngTableParams',function($scope,$stateParams,$location,Authentication,Reports,$filter,ngTableParams ) { $scope.reportBillingPeriod = 0; $scope.$watch('reportBillingPeriod',function(newValue,oldValue) { $scope.findReportData( newValue ); }); //$scope.reportBillingData = 0; $scope.findReportData = function( selectedMonth ){ var selectedPeriod = selectedMonth; if( selectedPeriod === null ) selectedPeriod = '0'; $scope.customers_report = Reports.customer_report({ monthReport: selectedPeriod },function( result ){ var data = result.customers; $scope.columns = [ { title: 'Account Name',field: 'accountName',visible: true,filter: { 'name': 'text' } },{ title: 'Gross Revenue',field: 'planTotalAmount',visible: true } ]; $scope.$watch('result',function () { $scope.tableParams.settings().$scope = $scope; $scope.tableParams.reload(); }); $scope.tableParams = new ngTableParams({ page: 1,// show first page count: 10,// count per page filter: { name: 'O' // initial filter } },{ total: data.length,// length of data getData: function($defer,params) { var orderedData = params.sorting() ? $filter('orderBy')(data,params.orderBy()) : data; $defer.resolve(orderedData.slice((params.page() - 1) * params.count(),params.page() * params.count())); //$scope.reportBillingData = new Date(); } }); }); }; }]);
$scope.$watch('result',function () { $scope.tableParams.settings().$scope = $scope; <<--nested scope is replacing!! $scope.tableParams.reload(); });
ngTable指令创建嵌套范围,其中包含指令的所有设置,因此您不应该使用ReportsController的范围替换它
你需要删除这一行
$scope.tableParams.settings().$scope = $scope;
你需要为ngTable指定所有参数,请看一下
这里In ngTables,running $scope.tableParams.reload() for the third time results in TypeError: Cannot set property ‘$data’ of null
UPDATE
并且最好采取ngTableParams初始化和$watch for findReportData函数之外的结果,以防止错误和不必要的重新初始化

我设置了plunk,试着让它看起来更像原始问题,并模拟httpservice,
但这没关系,所有数据访问都必须进入ngTableParams中的getData func,当设置所有需要调用的过滤器时(或者只是使用$plu中的$watch)你必须调用$scope.tableParams.reload();,您可以尝试在上面的输入中键入一些数字,数据将更新而没有问题.为清楚起见,删除了与排序,分页和过滤相关的所有代码,
所以getData如下所示:
getData: function($defer,params) { var selectedPeriod = $scope.reportBillingPeriod ; //selectedMonth; if( selectedPeriod === null ) selectedPeriod = '0'; $scope.customers_report = Reports.get({ //Reports.customer_report({ monthReport: selectedPeriod },function(result ){ var data = result.customers; $scope.tableParams.total(data.length); var orderedData = params.sorting() ? $filter('orderBy')(data,params.orderBy()) : data; $defer.resolve(orderedData.slice((params.page() - 1) * params.count(),params.page() * params.count())); }); }
并观察过滤器更改,如下所示:
$scope.reportBillingPeriod = 0; $scope.$watch('reportBillingPeriod',oldValue) { $scope.tableParams.reload(); });
更新3
删除了重复的调用getData func,编辑here
这个问题存在于reportBillingPeriod变量的$watch中,所以为了防止第二次数据上传,我们必须检查值是如何变化的,比如这里
$scope.reportBillingPeriod = defaultValue; $scope.$watch('reportBillingPeriod',oldValue) { //this how we prevent second call if (newValue!=oldValue) $scope.tableParams.reload(); });
