如何为 ng-repeat 元素赋予不同的填充样式？ [复制]

Question

http://skymics.com/Energy/sampleschematic.jpg 看到这张图片。我希望我的 6 个盒子在图片上方的 6 条垂直线上。我不知道如何给这个ng-repeat 赋予不同的填充样式我用过。我用过[ng-class] 但它不起作用。我已经搜索了互联网上所有关于ng-class的消息来源。我不知道我是否使用过它正确与否。这是必要的。请帮助。

<div style="background-color: white">

<div id="container" class="row" style="padding-left: 150px">
    <div class="col-md-6" ng-repeat="row in msg.payload"
         ng-class=" {'evenClass': $even, 'oddClass': $odd , 'firstClass':$first,'lastClass':$last} ">
        <div class="plan col-md-4">
            <h3>Voltage : {{row.Voltage}}
                <span ng-class="row.Switch " ng-if="row.Switch == 'OFF'"
                      style="background: red">{{row.Switch}}</span>
                <span ng-class="row.Switch" ng-if="row.Switch == 'ON'"
                      style="background: green">{{row.Switch}}</span>
            </h3>
            <script>
                $(document).ready(function () {
                    setInterval(function (blinker) {
                        $("span").fadeIn(500);
                        $("span").fadeOut(500);

                    }, 1000)

                });
            </script>
            <div class="Amp">Amp</div>
            <ul>
                <li><b>P1: </b>{{row.P1}}</li>
                <li><b>P2: </b>{{row.P2}}</li>
                <li><b>P3: </b>{{row.P3}}</li>
                <li><b>N: </b>{{row.N}}</li>
            </ul>
        </div>
    </div>
</div>

我的 CSS 是：

<style>
body, html {
    height: 100%;
    margin: 0;
    /*background: #303030;*/
}

.bg {
    /* The image used */
    background-image: url("http://skymics.com/Energy/sampleschematic.jpg");

    /* Full height */
    height: 100%;

    /* Center and scale the image nicely */
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
}

#container {
    /*margin: 100px auto;*/
    text-align: center;
    /*width: 892px; !*/
}

#container .plan {
    font: 12px 'Lucida Sans', 'trebuchet MS', Arial, Helvetica;
    text-shadow: 0 1px rgba(255, 255, 255, .8);
    background: #fff;
    border: 1px solid #ddd;
    color: #333;
    padding: 20px;
    /*width: 134px; !* plan width = 180 + 20 + 20 + 1 + 1 = 222px *!*/
    float: left;
    opacity: 0.9;
    position: relative;
}

.evenClass {

.oddClass {

.firstClass {

.lastClass {

Answer 1

你用错了ng-class！

实际使用方法如下-

ng-class="{'evenClass': $even, 'oddClass': $odd, 'firstClass': $first, 'lastClass': $last}"

对于在单个 var 中定义的类（例如 var className = 'bla';）-

ng-class="bla"
