Question

下午好，所以，我有一个名为“#dropDownDest”的下拉框我试图绑定此下拉列表中的JSON对象“dropdowndest”但无法执行此操作。你能告诉我我到底做错了什么吗？

 $('#dropDownDest').html('<pre>' + JSON.stringify(JSONOBJECT) + '</pre>');

这是返回JSON元素的示例：

请参阅http://jsfiddle.net/qxn7sry3/1/

您需要为选项值和文本选择一些值。您可以遍历对象中的数组，并将它们作为<option ...

附加到选择中

for (var i = 0; i < JSONOBJECT.items.length; i++) {
    var item = JSONOBJECT.items[i];
    $("#dropDownDest").append('<option value=' + item.id.videoId + '>' + item.snippet.title + '</option>');
}

尝试将JSON对象绑定到下拉列表
