Question

我需要帮助计算此ng-repeat中的ticket.number总数

HTML

<tr ng-repeat="tickets in listTickets | filter: searchText | orderBy: sortorder:reverse">
    <td>{{ tickets.match }}</td>
    <td>{{ tickets.number }}</td>
    <td>{{ tickets.company }}</td>
    <td>{{ tickets.contact }}</td>
    <td>{{ tickets.mail }}</td>
    <td>{{ tickets.phone }}</td>
    <td><button class="btn btn-info" ng-click="edit(tickets._id)">Edit</button> </td>
    <td><button class="btn btn-danger" ng-click="delete(tickets._id)">Radera</button></td>   
</tr>
<tr>
    <td colspan="8"> Total of: {{ totalTickets() }} tickets</td>
</tr>

 $scope.totalTickets = function(){

 }

您还可以使用过滤器来计算总计。

<tr ng-repeat="tickets in listTickets | filter: searchText | orderBy: sortorder:reverse">
    <td>{{ tickets.match }}</td>
    <td>{{ tickets.number }}</td>
    <td>{{ tickets.company }}</td>
    <td>{{ tickets.contact }}</td>
    <td>{{ tickets.mail }}</td>
    <td>{{ tickets.phone }}</td>
    <td><button class="btn btn-info" ng-click="edit(tickets._id)">Edit</button> </td>
    <td><button class="btn btn-danger" ng-click="delete(tickets._id)">Radera</button></td>   
</tr>
<tr>
    <td colspan="8"> Total of: <span data-ng-bind="tickets.total=(listTickets | total:'number')"></span> tickets</td>
</tr>

控制器.js

app.filter('total', function(){
    return function(input, property) {
        var total = 0;
        angular.forEach(input, function(value, key) { total += parseFloat(value[property]) });
        return total;
    }
})
