angularjs NG-风格：背景图像不工作 [英] angularjs ng-style: background-image isn't working

问题描述

我试图用角 NG-风格（我尝试过定制指令具有相同的行为），背景图像应用到一个div，但它似乎并不奏效。

I'm trying to apply a background image to a div by using the angular ng-style ( I tried a custom directive before with the same behaviour ), but it doesn't seem to be working.

<nav
    class="navigation-grid-container"
    data-ng-class="{ bigger: isNavActive == true }"
    data-ng-controller="NavigationCtrl"
    data-ng-mouseenter="isNavActive = true; $parent.isNavActive = true"
    data-ng-mouseleave="isNavActive = false; $parent.isNavActive = false"
    data-ng-show="$parent.navInvisible == false"
    data-ng-animate="'fade'"
    ng-cloak>

    <ul class="navigation-container unstyled clearfix">
        <li
            class="navigation-item-container"
            data-ng-repeat="(key, item) in navigation"
            data-ng-class="{ small: $parent.isNavActive, big: isActive == true }"
            data-ng-mouseenter="isActive = true; isInactive= false"
            data-ng-mouseleave="isActive = false; isInactive= true">

            <div data-ng-switch on="item.id">

                <div class="navigation-item-default" data-ng-switch-when="scandinavia">
                    <a class="navigation-item-overlay" data-ng-href="{{item.id}}">
                        <div class="navigation-item-teaser">
                            <span class="navigation-item-teaser-text" data-ng-class="{ small: isScandinavia }">{{item.teaser}}</span>
                        </div>
                    </a>
                    <span class="navigation-item-background" data-ng-style="{ 'background-image': 'public/img/products/{{item.id}}/detail/wide/{{item.images.detail.wide[0]}}' }"></span>
                </div>

                <div class="navigation-item-last" data-ng-switch-when="static">
                    <div class="navigation-item-overlay">
                        <div class="navigation-item-teaser">
                            <span class="navigation-item-teaser-text">
                                <img data-ng-src="{{item.teaser}}">
                            </span>
                        </div>
                    </div>
                    <span class="navigation-item-background">
                        <img class="logo" data-ng-src="{{item.images.logo}}">
                    </span>
                </div>

                <div class="navigation-item-default" data-ng-switch-default>
                    <a class="navigation-item-overlay" data-ng-href="{{item.id}}">
                        <div class="navigation-item-teaser">
                            <span class="navigation-item-teaser-text">{{item.teaser}}</span>
                        </div>
                    </a>
                    <span class="navigation-item-background" data-ng-style="{ 'background-image': 'public/img/products/{{item.id}}/detail/wide/{{item.images.detail.wide[0]}}' }"></span>
                </div>

            </div>
        </li>
    </ul>
</nav>

不过，如果我尝试做背景色，似乎是工作的罚款。我尝试了远程数据源和本地源太 http://lorempixel.com/g/400/200/sports/ ，既不工作。

推荐答案

的背景图片正确的语法是：

background-image: url("path_to_image");

有关NG式正确的语法是：

Correct syntax for ng-style is:

ng-style="{'background-image':'url(https://www.google.com/images/srpr/logo4w.png)'}">
