将值分配给哈希中的特定输入

Question

现在我正在使用iTunes搜索API并尝试从专辑的曲目列表的键/值对中提取数据，并将它们插入到特定的文本输入中。我能够在表格内完成this，但由于目前应用程序的设置，现在要求输入嵌套在一对div内。

值赋值工作在对象的键名与数据名属性匹配并插入该特定值的位置。该对象的对迭代通过.track-form div中输入的索引。但是由于某种原因，迭代器似乎在第二个键/值处停止。相反，它应该按照tracks对象的顺序填充行输入。

var tracks = [ 
 
    {discNumber: "01", trackNumber: "01", trackName: "Track 01"}, 
 
    {discNumber: "01", trackNumber: "02", trackName: "Track 02"}, 
 
    {discNumber: "01", trackNumber: "03", trackName: "Track 03"}, 
 
    {discNumber: "01", trackNumber: "04", trackName: "Track 04"}, 
 
    {discNumber: "01", trackNumber: "05", trackName: "Track 05"} 
 
]; 
 

 
$('.track-form').each(function() { 
 
    $(this).find('.track-input').val(function(i) { 
 
    var dataName  = $(this).data("name"), 
 
     camelCasedClass = toCamelCase(dataName); 
 
    return tracks[i][camelCasedClass]; 
 
    }); 
 
    
 
    function toCamelCase(name) { 
 
     var camelCase = name.replace(/-([a-z])/g, function(g) { 
 
     return g[1].toUpperCase(); 
 
     }); 
 

 
     return camelCase; 
 
    } 
 
});

.track-container { 
 
    display: inline-block; 
 
} 
 

 
.track-form:not(:first-of-type) { 
 
    margin-top: 5px; 
 
}

有你在“我”错误的功能 - 它总是返回0，因为它是在容器中的第一个输入。试试这个：

var tracks = [ 
 
    {discNumber: "01", trackNumber: "01", trackName: "Track 01"}, 
 
    {discNumber: "01", trackNumber: "02", trackName: "Track 02"}, 
 
    {discNumber: "01", trackNumber: "03", trackName: "Track 03"}, 
 
    {discNumber: "01", trackNumber: "04", trackName: "Track 04"}, 
 
    {discNumber: "01", trackNumber: "05", trackName: "Track 05"} 
 
]; 
 

 
$('.track-form').each(function(i) { 
 

 
    $(this).find('.track-input').val(function() { 
 
    var dataName  = $(this).data("name"), 
 
     camelCasedClass = toCamelCase(dataName); 
 
    return tracks[i][camelCasedClass]; 
 
    }); 
 
    
 
    function toCamelCase(name) { 
 
     var camelCase = name.replace(/-([a-z])/g, function(g) { 
 
     return g[1].toUpperCase(); 
 
     }); 
 

 
     return camelCase; 
 
    } 
 
});

.track-container { 
 
    display: inline-block; 
 
} 
 

 
.track-form:not(:first-of-type) { 
 
    margin-top: 5px; 
 
}
