基本上，我有一个链接，当单击它时，我会显示一个模式。现在我可以在模态上显示其他属性，例如标题，除了背景图片！urg！

这是模态：

<div class="modalContainer" ng-style="{'background-image':'url({{selectedMeal.url}})'}">

                <div id="modalHeader"> 
                <div style="padding-top: 10px;">{{selectedMeal.title}}</div>

                </div>
</div>

这些是链接：

<div ng-click='selectMeal(meal)' class="contentItem" ng-repeat='meal in recipes | filter:searchText' ng-style="{'background-image':'url({{ meal.url }})'}">
                    <span id="contentItemHeader">{{ meal.title }}</span>
                    <span id="contentItemLevel">{{ meal.level }}</span>
</div>
