目前正在开发Angular JS电视应用程序.该应用程序从api调用中获取数据.我试图从结果数组中获取图像.

这是mainController.js的代码

app.controller("mainController", function($scope, $http){
    $scope.apiKey = "b3e2e6f87d3aeec3075668a1bd4a78e2";
    $scope.init = function(){
        //api call requires format, apiKey, date, and days
        var today = new Date();
        //format apiDate according to the api specifications
        var apiDate = today.getFullYear() + ("0" + (today.getMonth()+1)) + today.getDate();
        $scope.results = [];
        console.log(apiDate);
        $http.jsonp('http://api.trakt.tv/calendar/premieres.json/' + $scope.apiKey + '/' + apiDate + '/' + 30 + '/?callback=JSON_CALLBACK').success(function (data){
            //connection successful
            //console.log(data);
            angular.forEach(data, function (value, index){
                var date = value.date;//stores the date of the tv shows
                angular.forEach(value.episodes, function (tvshow, …

我无法弄清楚这段代码中的类型错误是什么

import React from 'react';

interface IMenu {
  items: {
    title: string,
    active: boolean,
    label: string
  }[]
}


type Action =
  | { type: 'SET_ACTIVE', label: string }

const initialState: IMenu = {
  items: [
    { title: 'Home', active: false, label: 'home' },
    { title: 'Customer', active: false, label: 'customer' },
    { title: 'Employee', active: false, label: 'employee' },
    { title: 'Report', active: false, label: 'report' },
  ]
}

const reducer = (state: IMenu = initialState, action: Action) => { …

我正在尝试从 express 服务器提供静态资产，该服务器上也安装了 Apollo Server，但这是与express.static配置相关的问题。这是我的文件夹结构的屏幕截图

这是快速配置的代码。它位于里面/config/app.js

import express from 'express';
import bodyParser from 'body-parser';
import morgan from 'morgan';
import cookieParser from 'cookie-parser';
import cors from 'cors';
import path from 'path';

const PORT = process.env.PORT || 3001;
const environment = process.env.NODE_ENV || 'development';
const loggingType = environment === 'development' ? 'dev' : 'tiny';

const app = express();
app.use(
  bodyParser.json({ limit: 1024 * 1024 * 2000, type: 'application/json' })
);
app.use(morgan(loggingType));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, './assets/images')));

export default app;

如果我尝试访问 localhost:3001/images，它会说 …

我正在使用.net MVC5框架开发Web应用程序.我的视图从模型中获取信息,并在两个单独的选择元素中显示建筑类型和楼层数.但是,我只需要显示独特的建筑类型和楼层数信息.如果问题的形象下面

我不知道该怎么做.这是该页面的代码:

@model IEnumerable<BIRDSResidential.Models.ResidentialBuilding>
@{
    ViewBag.Title = "ResidentialBuilding";
}

<div class="row">
    <div class="col-md-3">
        <select>
            @foreach (var item in Model)
            {
                <option value="">@Html.DisplayFor(modelItem => item.type)</option>
            }
        </select>
    </div>
    <div class="col-md-3">
        <select>
            @foreach (var item in Model)
            {
                <option value="">@Html.DisplayFor(modelItem => item.stories)</option>
            }
        </select>
    </div>
    <div class="col-md-offset-5 col-md-1">
        <button type="button" class="btn btn-default">
            <span class="glyphicon glyphicon-info-sign"></span>
        </button>
    </div>
</div

编辑

我将上面的代码更新为以下内容:

<div class="row">
    <div class="col-md-3">
        @Html.DropDownList("ResidentialBuilding", new SelectList(Model.Select(x => x.type).Distinct()))
    </div>
    <div class="col-md-3">
        @Html.DropDownList("ResidentialBuilding", new SelectList(Model.Select(x => x.stories).Distinct()))
    </div>
    <div class="col-md-3"> …
