我正在尝试使用变量和另一个对象从我的对象中获取一个值。 第一个变量工作得很好，但是卡在第二个变量上，并尝试了很多事情而没有成功。
console.log(data.data.mengsels_data['mengsels_label_'+counter_i]);
console.log(data.data.mengsels_data['mengsels_label_'+counter_i[sessionStorage.language]]);
console.log(sessionStorage.language);
第一行返回；
Object {nl: "April", en: "April", de: ""}
第二行返回；
undefined
第三行返回
nl
我需要获取“四月”
稍后添加
在下面的示例中，data是通过ajax调用来检索的，它是原始的json，但是ajax将其传输到对象内部。
仅在此示例中，我以完整的ajax响应手动放置了“ var data”，在我的示例中，它没有转移到对象中。
我的目标是循环遍历每个图像，并以正确的语言拍摄图像和标签，这是图像的一部分。

nl是data.data.mengsels_data['mengsels_label_'+counter_i]的属性
和sessionStorage.language === nl。因此，您应该可以使用：
data.data.mengsels_data['mengsels_label_'+counter_i][sessionStorage.language]
根据新代码进行编辑：
您拥有的代码从0开始计数，但是数据从mengsels_label_1开始，这意味着在第一次迭代中，您正在寻找mengsels_label_0，该迭代不存在。尝试从1开始：
var data = {"code": "0","success": [],"error": [],"data": {"0": "1","mengsels_id": "1","1": "Data Removed","mengsels_name": "Data Removed","2": "-","mengsels_description": "-","3": "\/media\/mengsels\/data-removed\/data-removed-1.jpg","mengsels_cover": "\/media\/mengsels\/data-removed\/data-removed-1.jpg","4": "","mengsels_folder": "","5": "","mengsels_video": "","6": "1","mengsels_visible": "1","7": "{\"mengsels_name\":\"Data Removed\",\"mengsels_description\":\"-\",\"mengsels_cover\":\"\\\/media\\\/mengsels\\\/data-removed\\\/data-removed-1.jpg\",\"mengsels_img_1\":\"\\\/media\\\/mengsels\\\/data-removed\\\/data-removed-1.jpg\",\"mengsels_img_2\":\"\\\/media\\\/mengsels\\\/data-removed\\\/data-removed-2.jpg\",\"mengsels_img_3\":\"\\\/media\\\/mengsels\\\/data-removed\\\/data-removed-3.jpg\",\"mengsels_img_4\":\"\\\/media\\\/mengsels\\\/data-removed\\\/data-removed-4.jpg\",\"mengsels_img_5\":\"\\\/media\\\/mengsels\\\/data-removed\\\/data-removed-5.jpg\",\"mengsels_img_6\":\"\\\/media\\\/mengsels\\\/data-removed\\\/data-removed-6.jpg\",\"mengsels_img_7\":\"\",\"mengsels_img_8\":\"\",\"mengsels_img_9\":\"\",\"mengsels_img_10\":\"\",\"mengsels_label_1\":{\"nl\":\"Januari\",\"en\":\"Januari\",\"de\":\"\"},\"mengsels_label_2\":{\"nl\":\"Februari\",\"en\":\"Februari\",\"de\":\"\"},\"mengsels_label_3\":{\"nl\":\"Maart\",\"en\":\"March\",\"de\":\"\"},\"mengsels_label_4\":{\"nl\":\"April\",\"en\":\"April\",\"de\":\"\"},\"mengsels_label_5\":{\"nl\":\"Mei\",\"en\":\"May\",\"de\":\"\"},\"mengsels_label_6\":{\"nl\":\"Juni\",\"en\":\"June\",\"de\":\"\"},\"mengsels_label_7\":{\"nl\":\"\",\"en\":\"\",\"de\":\"\"},\"mengsels_label_8\":{\"nl\":\"\",\"en\":\"\",\"de\":\"\"},\"mengsels_label_9\":{\"nl\":\"\",\"en\":\"\",\"de\":\"\"},\"mengsels_label_10\":{\"nl\":\"\",\"en\":\"\",\"de\":\"\"}}","mengsels_data": {"mengsels_name": "Data Removed","mengsels_description": "-","mengsels_cover": "\/media\/mengsels\/data-removed\/data-removed-1.jpg","mengsels_img_1": "\/media\/mengsels\/data-removed\/data-removed-1.jpg","mengsels_img_2": "\/media\/mengsels\/data-removed\/data-removed-2.jpg","mengsels_img_3": "\/media\/mengsels\/data-removed\/data-removed-3.jpg","mengsels_img_4": "\/media\/mengsels\/data-removed\/data-removed-4.jpg","mengsels_img_5": "\/media\/mengsels\/data-removed\/data-removed-5.jpg","mengsels_img_6": "\/media\/mengsels\/data-removed\/data-removed-6.jpg","mengsels_img_7": "","mengsels_img_8": "","mengsels_img_9": "","mengsels_img_10": "","mengsels_label_1": {"nl": "Januari","en": "Januari","de": ""},"mengsels_label_2": {"nl": "Februari","en": "Februari","de": ""},"mengsels_label_3": {"nl": "Maart","en": "March","de": ""},"mengsels_label_4": {"nl": "April","en": "April","de": ""},"mengsels_label_5": {"nl": "Mei","en": "May","de": ""},"mengsels_label_6": {"nl": "Juni","en": "June","de": ""},"mengsels_label_7": {"nl": "","en": "","de": ""},"mengsels_label_8": {"nl": "","en": "","de": ""},"mengsels_label_9": {"nl": "","en": "","de": ""},"mengsels_label_10": {"nl": "","en": "","de": ""}}}};

答案 1 :(得分：0)
我认为您放错了]。您可以尝试以下代码吗？
console.log(data.data.mengsels_data['mengsels_label_'+counter_i]);
console.log(data.data.mengsels_data['mengsels_label_'+counter_i][sessionStorage.language]);
console.log(sessionStorage.language);
如果data.data.mengsels_data['mengsels_label_'+counter_i]等于Object {nl: "April", en: "April", de: ""}，则您的第二行应使用nl访问data.data.mengsels_data['mengsels_label_'+counter_i][sessionStorage.language]。
