function printData(data){
 var customers = data
  .split('~')
  .map((i, e) => {
   return i
   .split('#')
   .map((i, el) => {
    return [i.split('>')[0],i.split('>')[1]];
   })

  });

 // $.each(customers, (i, el) => {
 //  customers[i] = el.split('#');
 //  $.each(customers[i], (name, valor) => {

 //  })
 // })

 console.log(customers);
}

我可以帮您进行翻译。以下是内容的翻译：

我从一个源中获取到的数据是这样的字符串：

prop1>value1#prop2>value2~
prop1>value1#prop2>value2~
prop1>value1#prop2>value2

其中：

“~”用于分割行
“#”用于分割列
“>”用于分割属性:值

这是我实际使用的映射函数（其中data是字符串）：

function printData(data){

    var customers = data
        .split('~')
        .map((i, e) => {
            return i
            .split('#')
            .map((i, el) => {
                return [i.split('>')[0],i.split('>')[1]];
            })
        });

    console.log(customers);
}

我差不多懂了，但需要最后的帮助，在控制台上打印的内容如下所示：

而我想要得到的是像这样的内容：

Array {
    customerNumber:103,
    customerName:Atelier
}

替代：

Array{
    Array{
        0:customerNumber,
        1:103
    }
    Array{
        0:customerName,
        1:Atelier
    }
}

我尽力进行了解释，希望足够清晰易懂！

对于这种类型的问题，有帮助的是如果您提供输入和输出以及演示程序进行尝试。图片无法提供帮助。 - elclanrs

arr => ({[arr[0]]: arr[1]}) - Paul S.

@elclanrs 好的！我更新了它并提供了演示，如果您查看浏览器控制台，您就可以看到它。 - nais

传统的方式：var o = {}，r = i.split（'>'）; o [r [0]] = r [1]; 返回o; - dandavis

从以下开始：

[
 ["customerNumber",103     ],
 ["customerName","Atelier" ]
]

至：

 { customerNumber:103, customerName:"Atelier" }

如果你想这样做，你可以重新映射数组：

    var arr = [
      [
        ["customerNumber", 103],
        ["customerName", "Atelier"]
      ],
      [
        ["customerNumber", 105],
        ["customerName", "Atr"]
      ]
    ];

    var r = arr.map(x => {
      return {
        [x[0][0]]: x[0][1],
        [x[1][0]]: x[1][1]
      }
    });

    console.log(r)

$(document).ready(function() {
  printData("customerNumber>103#customerName>Atelier graphique#contactLastName>Schmitt#contactFirstName>Carine #phone>40.32.2555#addressLine1>54, rueRoyale#addressLine2>#city>Nantes#state>#postalCode>44000#country>France#salesRepEmployeeNumber>1370#creditLimit>21000#~customerNumber>112#customerName>Signal Gift Stores#contactLastName>King#contactFirstName>Jean#phone>7025551838#addressLine1>8489 Strong St.#addressLine2>#city>LasVegas#state>NV#postalCode>83030#country>USA#salesRepEmployeeNumber>1166#creditLimit>71800#~customerNumber>114#customerName>Australian Collectors, Co.#contactLastName>Ferguson#contactFirstName>Peter#phone>03 9520 4555#addressLine1>636 St KildaRoad#addressLine2>Level3#city>Melbourne#state>Victoria#postalCode>3004#country>Australia#salesRepEmployeeNumber>1611#creditLimit>117300#~customerNumber>119#customerName>La Rochelle Gifts#contactLastName>Labrune#contactFirstName>Janine #phone>40.67.8555#addressLine1>67, rue des CinquanteOtages#addressLine2>#city>Nantes#state>#postalCode>44000#country>France#salesRepEmployeeNumber>1370#creditLimit>118200#~")
})

function printData(data) {
  var customers = data
    .split('~')
    .map((i, e) => {
      return i
        .split('#')
        .map((i, el) => {
          var r = i.split('>');
          return {
            [r[0]]: r[1]
          };
        })

    });

  // $.each(customers, (i, el) => {
  //  customers[i] = el.split('#');
  //  $.each(customers[i], (name, valor) => {

  //  })
  // })

  console.log(customers);
}
