javascript - AngularJS：跨多个 div 的 ng-repeat

问题描述

我想让我的网站的一部分是图像和信息的拼贴，如下所示：

我的目标

我可以作为一系列 div 手动执行此操作：

<div class="options">
    <div class="option">
        <a href="https://www.handpickedhotels.co.uk/bailbrookhouse"><img class="opt_img" src="images/hotels/BBH.jpg"></a>
        <h3 class="centered" id="hotel_info">Bailbrook House Hotel<br>BA1 7JD<br>Approx Price: &pound;xx</h3>
    </div>
    <div class="option">
        <a href="https://www.travelodge.co.uk/hotels/75/Bath-Central-hotel"><img class="opt_img" src="images/hotels/bath_central_travelodge.jpg"></a>
        <h3 class="centered" id="hotel_info">Bath Central Travelodge<br>BA1 2EB<br>Approx Price: &pound;xx </h3>
    </div>
    <div class="option">
        <a href="https://www.travelodge.co.uk/hotels/361/Bath-Waterside-hotel"><img class="opt_img" src="images/hotels/bath_waterside_travelodge.jpg"></a>
        <h3 class="centered" id="hotel_info">Bath Waterside Travelodge<br>BA2 4JP<br>Approx Price: &pound;xx</h3>
    </div>
</div>
<div class="options">
    <div class="option">
        <a href="https://www.premierinn.com/gb/en/hotels/england/somerset/bath/bath-city-centre.html"><img class="opt_img" src="images/hotels/Bath_premier_inn.jpg"></a>
        <h3 class="centered" id="hotel_info">Bath City Centre Premier Inn<br>BA1 2BX<br>Approx Price: &pound;xx</h3>
    </div>
    <div class="option">
        <a href="https://www.yha.org.uk/hostel/yha-bath"><img class="opt_img" src="images/hotels/YHA.jpg"></a>
        <h3 class="centered" id="hotel_info">YHA Bath<br>BA2 6LA <br>Approx Price: &pound;xx </h3>
    </div>
    <div class="option">
        <a href="https://www.bailbrooklodge.co.uk/"><img class="opt_img" src="images/hotels/bailbrook_lodge.jpg"></a>
        <h3 class="centered" id="hotel_info">Bailbrook Lodge<br>BA1 7HZ<br>Approx Price: &pound;xx</h3>
    </div>

和以下CSS：

*{
    font-family: "Palatino Linotype", "Book Antiqua", Palatino, serif
}

#hotel_info{
    background-color: rgba(130, 130, 130,0.7);
    width: 80%;
}

.centered {
    position: absolute;
    width: 100%;
    top: 40%;
    left: 50%;
    transform: translate(-50%, -50%);
}

.options{
    width: 100%;
    overflow: hidden;
}

.option {
    position: relative;
    text-align: center;
    width: 33%;
    float:left;
}

.opt_img{
    width: 100%;
    opacity: 0.7;
}

我现在已经开始使用 AngularJS 来更轻松地显示这些信息。

我有 MainController.js

app.controller('MainController', function($scope){
    $scope.title = 'Hotels';
    $scope.hotels = [
        {
            name: 'Bailbrook House Hotel',
            postcode: "BA1 7JD",
            price: 0.00,
            website: "https://www.handpickedhotels.co.uk/bailbrookhouse",
            img: "images/hotels/BBH.jpg"
        },
        {
            name: "Bath Central Travelodge",
            postcode: "BA1 2EB",
            price: 0.00,
            website: "https://www.travelodge.co.uk/hotels/75/Bath-Central-hotel",
            img: "images/hotels/bath_central_travelodge.jpg"
        },
        {
            name: "Bath Waterside Travelodge",
            postcode: "BA2 4JP",
            price: 0.00,
            website: "https://www.travelodge.co.uk/hotels/361/Bath-Waterside-hotel",
            img: "images/hotels/bath_waterside_travelodge.jpg"
        },
        //... [and so on]
    ]
});

然后我使用了

<div ng-controller="MainController">
    <div class = "options" ng-repeat="hotel in hotels">
        <div class = "option">
            <a ng-href={{hotel.website}}><img class="opt_img" ng-src={{hotel.img}}></a>
            <h3 class="centered" id="hotel_info">{{hotel.name}}<br>{{hotel.postcode | uppercase}}<br>Approx Price: {{hotel.price | currency:'&pound;'}}</h3>
        </div>
    </div>
</div>

这将所有选项放在一起。我可以明白为什么会这样，因为它没有像我在手动制作时那样围绕每组 3 个选项创建选项 div。是否有可能通过 ng-repeat 实现这一目标，还是我需要重新考虑我是如何做到的？

我对网络开发非常陌生，所以请让您的答案对初学者友好，如果我必须要求澄清，请多多包涵。我也欢迎人们提出更好或更简单的做事方式，我只是使用 Codecademy 的 AngularJS 课程作为起点。

解决方案

这可以通过使用 css flex 属性轻松实现

<div ng-controller="MainController" class="hotel-container">
    <div class = "options" ng-repeat="hotel in hotels">
        <div class = "option">
            <a ng-href={{hotel.website}}><img class="opt_img" ng-src={{hotel.img}}></a>
            <h3 class="centered" id="hotel_info">{{hotel.name}}<br>{{hotel.postcode | uppercase}}<br>Approx Price: {{hotel.price | currency:'&pound;'}}</h3>
        </div>
    </div>
</div> 

.hotel-container {
   display: flex;
}
.options {
  width : 33.33%;
}
