Question

我有一个完整的obj.file循环存储在数组中的名称列表，并随机选择三个名称作为赢家。我想要如果选择名称，存储在数组中，然后推送到div。

js hide：false console：true babel：false - ＆gt; js - ＆gt;

j query

var members = [
    { 'Member_ID': 0, 'Member_Name': "Malon Namak" },
    { 'Member_ID': 1, 'Member_Name': "Tom Joseph" },
    { 'Member_ID': 2, 'Member_Name': "Noah Iaruel" },
    { 'Member_ID': 3, 'Member_Name': "Rodricco Simil" },
    { 'Member_ID': 4, 'Member_Name': "Nax Kev" },
    { 'Member_ID': 6, 'Member_Name': "Raphaela Seru" },

];

var $display = $("#display");
var $draw = $("#draw");
var count = 1;
var $random = $("#random");
var $head = $("#head");
var $slider_1 = ("#slider_1");
var $slider_2 = ("#slider_2");
var $slider_3 = ("#slider_3");
var els =[];
$('#random').click(function(){
    $('#random').attr("value", + (count++) + "/3" );

    var total = members.length,
        selected = Math.floor( Math.random() * total ),
        i = 0;

    console.log( "selected", selected );
    for (i=0; i<total; i++) {

        console.log( "for", i );
                setTimeout((function(i){
            return function(){

                console.log( "timeout", i );
                $display.text( members[i].Member_Name.toUpperCase() );
                if( i === selected ) {
                    $head.text("Winning!!");
                    $head.animate( {"font-size": "20px"}, "slow");
                    $display.animate( {"font-size": "40px"}, "slow");


                }
            };
        }(i)), i*250);





        if( i === selected ) {


        break;
        }
    }

    if (count == 4){
        $('#random').attr("disabled", true);
        $('#random').attr("value", "0");

        $draw.text("You have reach the limit");


    };

});

只需要获取您的获奖名称并使用text（）插入相应的div。如果三个获胜的名字是课程而不是id，那会更容易，但不要担心。

获奖名称也会被推送到els数组中，该数组被假定为您要保留名称的数组。

在评论中使用您的代码制作代码片段。
