我有一个对象数组:

var array = [(id, name, value),(id, name, value)]; //and so on

如何使数组按属性名称的升序排序(array[i][1])？

我试过这样做:array[i][1].sort(),但这不起作用.

请帮我!

编辑:数组可以包含两个以上的对象!它可以包含数百个.

编辑: 为什么这个问题被标记为重复,当在"重复"问题之前2年被问到？

从这个原始问题,我将如何在多个字段上应用排序？

使用这种略微适应的结构,我如何排序城市(升序)然后价格(降序)？

var homes = [
    {"h_id":"3",
     "city":"Dallas",
     "state":"TX",
     "zip":"75201",
     "price":"162500"},
    {"h_id":"4",
     "city":"Bevery Hills",
     "state":"CA",
     "zip":"90210",
     "price":"319250"},
    {"h_id":"6",
     "city":"Dallas",
     "state":"TX",
     "zip":"75000",
     "price":"556699"},
    {"h_id":"5",
     "city":"New York",
     "state":"NY",
     "zip":"00010",
     "price":"962500"}
    ];

我喜欢这个事实而不是给出一个通用方法的答案.在我计划使用此代码的地方,我将不得不对日期以及其他内容进行排序."引导"物体的能力似乎很方便,如果不是有点麻烦.

我试图将这个答案构建成一个很好的通用示例,但我没有太多运气.

您如何按距离对这些对象进行排序.那么你有从最小距离到最大距离排序的对象？

Object { distance=3388, duration="6 mins", from="Lenchen Ave, Centurion 0046, South Africa", more...}

Object { distance=13564, duration="12 mins", from="Lenchen Ave, Centurion 0046, South Africa", more...}

Object { distance=4046, duration="6 mins", from="Lenchen Ave, Centurion 0046, South Africa", more...}

Object { distance=11970, duration="17 mins", from="Lenchen Ave, Centurion 0046, South Africa", more...}

我总是这样成功地对我的数组进行排序(当我不想要标准的词典排序时):

var arr = […] // some numbers or so
arr.sort(function(a, b) {
    return a > b;
});

现在,有人告诉我这是错的,我需要return a-b改为.这是真的,如果是的话为什么？我测试了我的比较功能,它有效!另外,为什么我的解决方案在出错时会如此常见？

我想创建一个(非匿名)函数,按键按字母顺序对对象数组进行排序name.我只编写直接的JavaScript代码,所以框架至少对我没用.

var people = [
    {'name': 'a75', 'item1': false, 'item2': false},
    {'name': 'z32', 'item1': true,  'item2': false},
    {'name': 'e77', 'item1': false, 'item2': false}
];

我知道这必须相对简单,但我有一个JSON数据集,我想按日期排序.到目前为止,我每次都遇到问题.现在我将日期存储为this.lastUpdated.如果有帮助我可以访问jquery,但我意识到.sort()是本机JS.提前致谢.

使用Javascript,我想知道如何根据每个对象中的字符串值按字典顺​​序对一组对象进行排序.

考虑:

[
 {
    "name" : "bob",
    "count" : true
    "birthday" : 1972
 },
      {
    "name" : "jill",
    "count" : false
    "birthday" : 1922
 },
      {
    "name" : "Gerald",
    "count" : true
    "birthday" : 1920
 }
 ]

如何按名称按字母顺序对数组进行排序？名称值是用户名,所以我想保留字母大小写.

我有一个名为的对象数组canvasObjects.

每个对象都有一个名为的属性z.

我想基于对象对这个数组进行排序z.我如何使用该sort()方法执行此操作？

这是我的JSON文件的一个例子.

[
    {"Variable":"Hello","Variable1":20}, {"Variable":"Hi","Variable1":30},
    {"Variable":"How","Variable1":40}, {"Variable":"Who","Variable1":50},
    {"Variable":"Where","Variable1":60}, {"Variable":"This","Variable1":100},
    {"Variable":"Pork","Variable1":10}, {"Variable":"Creep","Variable1":90},
    {"Variable":"Mega Creeps","Variable1":80}, {"Variable":"LOL","Variable1":0},
    {"Variable":"ROFL","Variable1":0}, {"Variable":"LMAO","Variable1":0},
    {"Variable":"POP","Variable1":0}, {"Variable":"LOVE","Variable1":0},
    {"Variable":"PICK","Variable1":0}, {"Variable":"WHIZ","Variable1":0},
    {"Variable":"BORED","Variable1":0}, {"Variable":"KILLAH","Variable1":0},
    {"Variable":"LOLLING","Variable1":0}, {"Variable":"HALOO  HALOO","Variable1":0}
]

如何才能从最高的Variable1号码中获得前10名？但是要将JSON文件作为相同的格式传递.

我有一个ajax调用,返回一个相当复杂的JSON对象,我很难对它进行排序.

我的电话:

$.post('/reports-ajax',arguments, function(data) {}

响应:

}

我用一个标准的每个调用来检查函数并用highcharts做一些很棒的东西,但现在我试图通过net_total调用对响应进行排序,我无法弄明白.

我尝试了.sort()它错误,它不是一个功能.我已经阅读了一段时间,但我猜我找不到合适的结果.这看起来很有希望:对一组JavaScript对象进行排序,但它失败了,.sort而不是一个函数.似乎大多数.sort都在[]数组上而不是完整的对象..

任何帮助将不胜感激.
