Question

我想将两个参数传递给自定义过滤器＆＃39; 从＆＃39; 和＆＃39;到＆＃39; 到我自定义的过滤器中在我的控制器中创建。

在这里，您可以看到我创建的自定义过滤器：

    vm.filterMinutes = function (prop, from, to) {
        return function (item) {
            return item[prop] >= from && item[prop] <= to;
        };
    };

视图如下：

<label>Search from: <input ng-model="fromMinutes"></label>
<label>Search from: <input ng-model="toMinutes"></label>

    <tr style="cursor: pointer;" ng-repeat="student in AdminReportsWorksnaps.data | filter: AdminReportsWorksnaps.filterMinutes('totalMinutes', fromMinutes,toMinutes)">
                <td>{{ student.studentId }}</td>
                <td>{{ student.firstName }}</td>
                <td>{{ student.lastName }}</td>
                <td>{{ student.municipality }}</td>
                <td class="total success">{{ student.totalMinutes | number}}</td>
   </tr>

由于某种原因，这不起作用。好吧，如果我这样调用过滤器：filter: AdminReportsWorksnaps.filterMinutes('totalMinutes', 5000,6000)"它的工作原理非常好..我只是看不出如何从文本框中传递输入值。

将其作为:分隔（假设您使用controllerAs模式与vm别名）

ng-repeat="student in AdminReportsWorksnaps.data | filter: AdminReportsWorksnaps.filterMinutes: 'totalMinutes': fromMinutes: toMinutes"

因此，在上述情况下，您需要在过滤器中预期4个参数，第一个参数为AdminReportsWorksnaps.data，第二个参数为totalMinutes，第三个fromMinutes＆amp;最后一个是toMinutes值

vm.filterMinutes = function (collection, prop, from, to) {
    //collection would have 
    console.log("AdminReportsWorksnaps.data", collection)
    console.log(prop, from, to);
    return (collection || []).filter(function (item) {
        return item[prop] >= from && item[prop] <= to;
    });
};

It look like you're using a controllerAs, so why don't use the controller alias for the models too :

<label>Search from: <input ng-model="AdminReportsWorksnaps.fromMinutes"></label>
<label>Search from: <input ng-model="AdminReportsWorksnaps.toMinutes"></label>

<tr style="cursor: pointer;" ng-repeat="student in AdminReportsWorksnaps.data | filter: AdminReportsWorksnaps.filterMinutes('totalMinutes', AdminReportsWorksnaps.fromMinutes, AdminReportsWorksnaps.toMinutes)">
    <td>{{ student.studentId }}</td>
    <td>{{ student.firstName }}</td>
    <td>{{ student.lastName }}</td>
    <td>{{ student.municipality }}</td>
    <td class="total success">{{ student.totalMinutes | number}}</td>

It should works like that.
