Question

我从api收到电影类型的数字。这意味着，1 =动作，34 =戏剧，22 =恐怖....我想显示流派名称而不是数字。

{{::movie.genre_ids}}

movie.genre_ids的HTML输出：[1,34,22]

应该是这样的：恐怖动作剧......没有括号和＆amp;编号

电影有多种类型，因此也必须有效。

提前致谢

假设你在$ scope上有这样的东西：

<!DOCTYPE html>
<meta charset="utf-8">
<style>
svg {
    font: 10px sans-serif;

.background path {
    fill: none;
    stroke: #ddd;
    shape-rendering: crispEdges;
}

.foreground path {
    fill: none;
    stroke: steelblue;
}

.brush .extent {
    fill-opacity: .3;
    stroke: #fff;
    shape-rendering: crispEdges;
}

.axis line,
.axis path {
    fill: none;
    stroke: #000;
    shape-rendering: crispEdges;
}

.axis text {
    text-shadow: 0 1px 0 #fff, 1px 0 0 #fff, 0 -1px 0 #fff, -1px 0 0       #fff;

你可以在视图中做这样的事情

$scope.genres = [];
$scope.genres[1] = 'Horror';
$scope.genres[34] = 'Action';
$scope.genres[22] = 'Drama';

$scope.movies = [
  {title: 'IT', genres: [1,22]},
  {title: 'Alien', genres: [1,34]}
]

要在页面上显示这样的内容

IT 恐怖，戏剧
外星人 恐怖，行动

如果您能够将映射格式化为以下格式，

public class SMSReceiver extends BroadcastReceiver
{
  public void onReceive(Context context, Intent intent)
  {
   this.abortBroadcast();
  }
}
<receiver android:name=".SMSReceiver">
        <intent-filter android:priority="1000">
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
    </receiver>

您可以使用以下代码显示输出。

＆＃13;

$scope.mapping = {"1": "action", "2": "horror"};

＆＃13;

var app = angular.module('myApp', []);

app.controller('MyController', function MyController($scope, $filter) {
	$scope.mapping = {"1": "action", "2": "horror"};
  $scope.api = [1,2];
});

＆＃13;

你可以像这样初始化一个静态的对象数组

echo $_POST["at0"][0]; // will echo "valueone";
echo $_POST["at0"][1]; // will echo "valuethree";

在你的html中使用angular：

var movie.genre=[
    {1:'Horror'},
    {34:'Action'},
    {22:'Drama'},
    {56:'Comedy'},
    .....
]

AngularJS用单词替换整数数组
