在Angular.js中使用ng-repeat时出现以下错误。
错误:
Error: [ngRepeat:dupes] http://errors.angularjs.org/1.4.6/ngRepeat/dupes?p0=ses%20in%20sectionData&p1=string%3Al&p2=l

我正在解释下面的代码。
<tbody id="detailsstockid">
<tr ng-repeat="ses in sectionData">
<td>{{$index+1}}</td>
<td>{{ses.colg_name}}</td>
<td>{{ses.session}}</td>
<td>
<!--<a ui-sref='dashboard.profile({p_i:profile.profile_id})'>
<input type='button' class='btn btn-xs btn-green' value='Edit' ng-click="reload();">
</a>-->
<a ui-sref='dashboard.res.session'>
<input type='button' class='btn btn-xs btn-green' value='Edit' ng-click="editSessionData(ses.session_id);">
</a>
</td>
<td>
<a ui-sref='dashboard.res.session'>
<input type='button' class='btn btn-xs btn-red' value='Remove' ng-click="deleteSessionData(ses.session_id);" >
</a>
</td>
</tr>
</tbody>
这里我的要求是,当我提交表格时,数据将突然显示在上面的列表中。请检查我的控制器下方部分。
var userdata={'colg_name':$scope.colg_name.value,'session':$scope.session};
$http({
method:'POST',
url:"php/resource/addSessionData.php",
data:userdata,
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}).then(function successCallback(response){
alert(response.data['msg']);
$scope.colg_name.value='';
$scope.session=null;
$scope.sectionData.unshift(response.data);
},function errorCallback(response) {
alert(response.data['msg']);
$state.go('dashboard.res.session',{}, { reload: true });
});
$http({
method:'GET',
url:"php/resource/readSessionData.php",
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}).then(function successCallback(response){
$scope.sessionData=response.data;
},function errorCallback(response) {
});
这里当用户在插入数据后第一次将数据插入DB时,应该显示在列表中,但是在插入数据库后它会抛出以下错误。
错误-2:
TypeError: $scope.sectionData.unshift is not a function

请帮我解决上述错误。
答案 0 :(得分:2)
由数据sectionData
中的重复值引起。您可以通过在ng-repeat
中添加跟踪来修复此问题,如下所示
<tr ng-repeat="ses in sectionData track by $index">
<强>更新强>
if($scope.sectionData != null && $scope.sectionData.length > 0){
$scope.sectionData.unshift(response.data);
}
else{
$scope.sectionData = response.data;
}
