显示数组中的图片吗

显示数组中的图片吗

我正在制作一个rpg游戏。因此,我正在尝试创建一个for循环,该循环将为屏幕生成此按钮,到目前为止,

$(document).ready(function() {
    var imgArray = new Array();
    imgArray[0] = new Image();
    imgArray[0].src = 'assets/images/young_link.jpg';

    //var test = "<img src= '../images/young_link.jpg'>";
    //var young_hero = ["young_link","young_zelda","impa", "malon"];
    var young_hero = ["young_link"];
    //var hero_images = [test];

    for (var i = 0; i < young_hero.length; i++) {
        var hero_btns = $("<buttons>");
        hero_btns.addClass("hero");
        hero_btns.attr("data-hero" , young_hero[i]);
        hero_btns.attr("data-image" , imgArray[i]);
        hero_btns.text(imgArray[i]);
        hero_btns.text(young_hero[i]);
        $("#buttons").append(hero_btns);
    }
});


问题在于它没有将图像放在按钮上。

最佳答案

为了向按钮添加图像,您不仅需要做data-image的工作,还需要实际创建<img>标记并将其提供为图像的来源。然后,您将需要使用css在按钮中正确排列图像。

我已经更新了您的代码,以将图像添加到第一个按钮。


$(document).ready(function() {
    var imgArray = new Array();
    imgArray[0] = new Image();
    imgArray[0].src = 'https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcT7o2tCpqvs_XRpvtHbuRe9KwkzydiVhWLJ6YVTkQcpkev09w0MBCgNu2w';

    //var test = "<img src= '../images/young_link.jpg'>";
    var young_hero = ["young_link","young_zelda","impa", "malon"];
    //var young_hero = ["young_link"];
    //var hero_images = [test];

    for (var i = 0; i < young_hero.length; i++) {
        var hero_btns = $("<button>"); // changed from <buttons>
        hero_btns.addClass("hero");
        hero_btns.attr("data-hero" , young_hero[i]);
        //hero_btns.text(imgArray[i]);
        hero_btns.text(young_hero[i]);
        hero_btns.append(imgArray[i])
        $("#buttons").append(hero_btns);
    }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="buttons">

  </div>
