angularjs - How to Set Background image of div with ng-style

Question

Basically i have a link, and when it's clicked, i display a modal. Now i can display other properties on the modal like title except the background Image ! urghhh !

This is the modal:

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

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

                </div>
</div>

These are the links:

<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>

Answer 1

You have made some mistakes using single quotes, you have to take your variable outside the single quotes.

For this div

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

This part is being treated as a string

'url({{selectedMeal.url}})'

Whereas you would want angular to parse this variable

{{selectedMeal.url}}

So to solve this, the correct syntax is

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