如何将 JSON 正确加载到引导选项卡

Question

我正在尝试将 JSON 数据动态加载到 Bootstrap 3 选项卡中，就像下面的代码一样。我能够加载导航选项卡，但在加载内容时没有任何成功。我该如何解决它？

   var data = {
        "action":
            [
                { "id": "1001", "name": "Matrix" },
                { "id": "1002", "name": "IP Man" },
                { "id": "1003", "name": "Revenge" }
            ],
        "comedy":
            [
                { "id": "2001", "type": "Iceman" },
                { "id": "2002", "type": "Pat & Mat" },
                { "id": "2003", "type": "Sugar" }
                 ],
        "animation":
            [
                { "id": "3001", "type": "Frozen" },
                { "id": "3002", "type": "Tangled" },
                { "id": "3003", "type": "Croods" }
                 ]
    
    };
    
    for (var i in data) {
      $('.nav-tabs').append('<li role="presentation" class=""><a href="#' + i + '" aria-controls="' + i + '" role="tab" data-toggle="tab">' + i + '</a></li>');
    
    }
      for (var j = 0; j < data[i].length; j++) {
        var obj = data[i][j];
        $('.tab-content').append('<div role="tabpanel" class="tab-pane" id="' + obj.name + '">' + obj.name + '</div>');
     }

$('.nav-tabs li').eq(0).addClass('active');

body{padding:30px;}

Answer 1

你的代码中有几个逻辑和拼写错误。低于工作版本。

拼写错误：在"动作"中，您磁带参数名称，但在其他两个参数名称中是类型。

逻辑：1.使用.append导致关闭HTML元素，因此您需要构建一个完整的字符串，然后附加。2.您必须在第二个循环后关闭父for循环，否则，您始终只有一个选项卡。

var data = {
        "action":
            [
                { "id": "1001", "type": "Matrix" },
                { "id": "1002", "type": "IP Man" },
                { "id": "1003", "type": "Revenge" }
            ],
        "comedy":
            [
                { "id": "2001", "type": "Iceman" },
                { "id": "2002", "type": "Pat & Mat" },
                { "id": "2003", "type": "Sugar" }
                 ],
        "animation":
            [
                { "id": "3001", "type": "Frozen" },
                { "id": "3002", "type": "Tangled" },
                { "id": "3003", "type": "Croods" }
                 ]
    
    };
    
    for (var i in data) {
      $('.nav-tabs').append('<li role="presentation" class=""><a href="#' + i + '" aria-controls="' + i + '" role="tab" data-toggle="tab">' + i + '</a></li>');
    
      var div = '<div role="tabpanel" class="tab-pane" id="' + i + '">';
      
      for (var j = 0; j < data[i].length; j++) {
        var obj = data[i][j];
        div += '<div id="' + obj.id + '">' + obj.type + '</div>';
     }
     $('.tab-content').append(div);
}
$('.nav-tabs li').eq(0).addClass('active');
$('.tab-content div').eq(0).addClass('active');
