Question

我用这个。

<!DOCTYPE html>
<html lang='en' ng-app="main" ng-controller="Main">
<head>
    <meta charset="UTF-8"/>
    <meta ng-if="isAndroidWelcome()" name="viewport" content="width=900">

但元标记始终处于活动状态，无关紧要isAndroidWelcome()返回true。

这是主控制器的代码

var main = angular.module("main", ['ngDialog', 'angularFileUpload', 'ngCookies',
    'angularUtils.directives.dirPagination', 'infinite-scroll',
    'ngTagsInput', 'tiksem-keyboard', 'ngSanitize' /*HTML_TEMPLATES_PLACEHOLDER*/]);
main.controller("Main", function($http, $element, $timeout, $scope, $locale, $location, $cookies){
    ControllerUtils.initController($scope, $location);

    var setLang = $scope.setLang = function(lang) {
        $scope.lang = lang;
        $scope.tr = TRANSLATION[lang] || TRANSLATION["en"];
    };
    //setLang($locale.id.split("-")[0]);
    setLang("ru");

    var onSignedInChanged = [];

    var isMobile = $scope.isMobile = Utilities.mobilecheck();
    var isAndroid = $scope.isAndroid = Utilities.isAndroid();
    $scope.isAndroidWelcome = function() {
        return $scope.getPath() == "welcome" && isAndroid;
    };

Answer 1

这里有更多这样的事情：

<meta ng-change="isAndroidWelcome()" ng-model="viewport" content="width=900">

通过这种方式，您可以在您创建的ng-model（视口）上使用Angular控制器来执行isAndroidWelcome（）函数。

在元标记中使用AngularJs表达式
