我在测试期间使用静态.json文件加载表。这适用于以下控制器代码:
function dashboardResearchPubCtrl($scope, $http, dataService, DTOptionsBuilder, DTColumnBuilder) {
var vm = this;
vm.dtInstance = {};
vm.dtOptions = DTOptionsBuilder.newOptions()
.withOption('ajax', {
"contentType": "application/json; charset=utf-8",
dataType: "json",
"url": "/api/research-pub.json",
"type": "GET",
"data": function ( d ) {
return JSON.stringify(d);
}
})
.withOption('processing', true)
.withOption('serverSide', true)
.withOption('filter', false)
.withOption('fnPreDrawCallback', function () {
$("#overlay").show();
})
.withOption('fnDrawCallback', function () {
$("#overlay").hide();
})
.withPaginationType('full_numbers');
vm.dtColumns = [
DTColumnBuilder.newColumn('content_id').withTitle('Id'),
DTColumnBuilder.newColumn('content_title').withTitle('Title')
];
}
但是,如果我将网址从“url”:“/ api / research-pub.json”(本地.json文件)更改为“url”:“/ api / research-pub”(xhr端点(它呈现与文件相同的json),然后数据表加载数据,但我得到数据表警告警告消息:table_id = dataTable Datatables警告:id'content_id'请求未知参数... Chrome网络显示xhr响应数据,但数据表中没有任何内容。
是否需要添加或删除参数才能使xhr正常工作?谢谢!
这是视图代码:
<div ng-controller="dashboardResearchPubCtrl as vm">
<table id="dataTable" datatable="" dt-instance="vm.dtInstance" dt-options="vm.dtOptions" dt-columns="vm.dtColumns" class="table table-striped table-bordered table-hover dataTable"></table>
</div>
和json回复:
[[{"rating_cnt":140,"rating_avg":4,"content_id":"122","content_title":"Business-Driven Dealer Training","content_metadata":null,"access_level":"Member","industry":"Automotive","audience_level":"Intermediate","publish_date":"2007-01-24T00:00:00.000Z"},
{"rating_cnt":350,"rating_avg":4,"content_id":"100","content_title":"HR Training & Assessment","content_metadata":null,"access_level":"Member","industry":"Aerospace","audience_level":"Beginner","publish_date":"2014-11-14T00:00:00.000Z"}
]]
答案 0 :(得分:1)
有一些问题:
data()
回调应为dataSrc()
JSON.stringify()
..?这没有意义.withOption('serverSide', true)
是一个错误,因为JSON不支持它在d[0]
中回复dataSrc()
,因为回复位于[[{},{}..]
表单上将会有效:
vm.dtOptions = DTOptionsBuilder.newOptions()
.withOption('ajax', {
url: "/api/research-pub.json",
dataSrc: function ( d ) {
return d[0]
}
})
...

如果不需要serverSide: true
,我建议改为使用承诺:
vm.dtOptions = DTOptionsBuilder.fromFnPromise(function() {
var defer = $q.defer();
$http.get('/api/research-pub.json').then(function(result) {
defer.resolve(result.data[0]);
});
return defer.promise;
})
