Question

我正在尝试从每个特定的动态创建的div输入中获取值，但是我很难获得它们。我想在我的按钮点击上获得“this”特定输入的输入值，但它只是给我第一个div输入值，无论我点击什么按钮。任何帮助将不胜感激！

    getGames().done(function(results){
        $.each(results, function (i, gameData){
            $.each(gameData, function(key, game){

                var gamesHome = game.home_team_conference;
                var gamesAway = game.away_team_conference;


                if(gamesHome == "Big 12" || gamesAway == "Big 12"){
                    // console.log(this);
                    var gameId = game.id;
                    var homeTeam = game.home_team;
                    var awayTeam = game.away_team;
                    var pointTotal = game.total_points_bet;
                    var gameTime = game.game_time_hour;
                    var gameDate = game.game_time_date;
                    var gameId = game.id;
                    var network = game.broadcast_network;
                    var hue = 'rgb(' + (Math.floor(Math.random() * 256)) + ',' + (Math.floor(Math.random() * 256)) + ',' + (Math.floor(Math.random() * 256)) + ')';
                    var hueTwo = 'rgb(' + (Math.floor(Math.random() * 256)) + ',' + (Math.floor(Math.random() * 256)) + ',' + (Math.floor(Math.random() * 256)) + ')';
                    var self = $(this);

                $('.wrapper').append('\

如果您尝试获取lib的值，则需要在inputs上使用val()。但您使用的是主inputs的{{1}}。您使用attr的方式不正确。此外，如果您将游戏的div添加为主attr的父属性，则会更容易。试试这个：

id

试图获取动态创建的输入的值，我将如何获得“this”值？
