仅从 object 的键替换单引号 Javascript

Question

希望每个人都很好，我有一个棘手的问题，从 RPA 应用程序我得到这个 object：

let data = {
      Fecha: '2022-12-14T00:00:00',
      Hora: '1899-12-31T16:14:00',
      'Aten.': 73,
      ' Nro  Ing ': 0,
      Cerrada: 'S',
      '    ': '    ',
      ' Nombre  Atenci¾n ': 'AMBULATORIA',
      'EstadoHC.Electronica': '   -   ',
      Profesional: ' GARCIA  CHAVERRA  MADELEINE ',
      Especialidad: ' MEDICINA  GENERAL ',
      Diagnostico: ' ENFERMEDAD  CARDIACA,  NO  ESPECIFICADA ',
      'Num.Cta': 0
    }

如您所见，object 的密钥，其中一些有点奇怪，我想做的是替换密钥中的单引号，以获得[Nombre Atenci¾n]值。

我尝试的是用 JSON.parse 解析新的 object 中的 object 并替换开头和结尾的空格，如下所示：

let data2 = JSON.parse(JSON.stringify(data).replace(/"\s+|\s+"/g,'"'));

然后我尝试迭代第二个 object，以获取之前提到的键的具体值，在替换空格和字符之后，但是我得到的是未定义而不是“AMBULATORIA”

for(let dat in data2){
    dat = dat.replace(/\s\s+/g, '').replace("¾", 'o');
    console.log(dat.NombreAtencion)
}

为什么我使用 for 来迭代“一个单一的对象”是因为我得到了一个像那个对象的数组，所以我必须对每个 object 使用相同的处理。

object 键中没有单引号。 在 object 文字中，您可以将属性名称放在引号中（单引号或双引号）。 引号只是分隔符，不是属性名称的一部分。 仅当属性名称包含属性文字中不允许的字符时才需要这样做（这对您的所有示例都是如此 - 空格和.在属性名称中完全有效，但在属性名称文字中则无效）。

所以没有什么可做的，你的 object已经有属性名称，其中没有这些引号。 您可以通过查看属性名称来判断：

 let data = { Fecha: '2022-12-14T00:00:00', Hora: '1899-12-31T16:14:00', 'Aten.': 73, ' Nro Ing ': 0, Cerrada: 'S', ' ': ' ', ' Nombre Atenci¾n ': 'AMBULATORIA', 'EstadoHC.Electronica': ' - ', Profesional: ' GARCIA CHAVERRA MADELEINE ', Especialidad: ' MEDICINA GENERAL ', Diagnostico: ' ENFERMEDAD CARDIACA, NO ESPECIFICADA ', 'Num.Cta': 0 }; console.log("Property names:"); for (const name of Object.keys(data)) { console.log(name); } console.log("Value of property Aten.: ", data["Aten."]);

 .as-console-wrapper { max-height: 100%;important; }

如果您想使这些属性名称合理化，以便它们是您可以在属性名称文字中使用的东西（因此它们遵循 JavaScript 属性名称的标准约定），您可以使用原始名称和新名称的Map喜欢使用，然后使用属性的新名称创建一个新的 object：

 let data = { Fecha: "2022-12-14T00:00:00", Hora: "1899-12-31T16:14:00", "Aten.": 73, " Nro Ing ": 0, Cerrada: "S", " ": " ", " Nombre Atenci¾n ": "AMBULATORIA", "EstadoHC.Electronica": " - ", Profesional: " GARCIA CHAVERRA MADELEINE ", Especialidad: " MEDICINA GENERAL ", Diagnostico: " ENFERMEDAD CARDIACA, NO ESPECIFICADA ", "Num.Cta": 0, }; const nameMap = new Map([ ["Fecha", "fecha"], ["Hora", "hora"], ["Aten.", "aten"], [" Nro Ing ", "norIng"], ["Cerrada", "cerrada"], [" ", "spaces"], // Or whatever [" Nombre Atenci¾n ", "nombreAtencion"], ["EstadoHC.Electronica", "estadoHCElectronica"], ["Profesional", "profesional"], ["Especialidad", "especialidad"], ["Diagnostico", "diagnostico"], ["Num.Cta", "numCta"], ]); const updated = Object.fromEntries( Object.entries(data).map(([name, value]) => [nameMap.get(name)?? name, value]) ); console.log(updated);

 .as-console-wrapper { max-height: 100%;important; }

或者使用简单的循环代替Object.fromEntries 、 Object.entries和map ：

 let data = { Fecha: "2022-12-14T00:00:00", Hora: "1899-12-31T16:14:00", "Aten.": 73, " Nro Ing ": 0, Cerrada: "S", " ": " ", " Nombre Atenci¾n ": "AMBULATORIA", "EstadoHC.Electronica": " - ", Profesional: " GARCIA CHAVERRA MADELEINE ", Especialidad: " MEDICINA GENERAL ", Diagnostico: " ENFERMEDAD CARDIACA, NO ESPECIFICADA ", "Num.Cta": 0, }; const nameMap = new Map([ ["Fecha", "fecha"], ["Hora", "hora"], ["Aten.", "aten"], [" Nro Ing ", "norIng"], ["Cerrada", "cerrada"], [" ", "spaces"], // Or whatever [" Nombre Atenci¾n ", "nombreAtencion"], ["EstadoHC.Electronica", "estadoHCElectronica"], ["Profesional", "profesional"], ["Especialidad", "especialidad"], ["Diagnostico", "diagnostico"], ["Num.Cta", "numCta"], ]); const updated = {}; for (const name of Object.keys(data)) { const newName = nameMap.get(name)?? name; updated[newName] = data[name]; } console.log(updated);

 .as-console-wrapper { max-height: 100%;important; }

或者如果你想用一些规则来做，这里有一个处理. 作为一个空格，删除多余的空格，并转换为标准的驼峰式大小写：

 let data = { Fecha: "2022-12-14T00:00:00", Hora: "1899-12-31T16:14:00", "Aten.": 73, " Nro Ing ": 0, Cerrada: "S", " ": " ", " Nombre Atenci¾n ": "AMBULATORIA", "EstadoHC.Electronica": " - ", Profesional: " GARCIA CHAVERRA MADELEINE ", Especialidad: " MEDICINA GENERAL ", Diagnostico: " ENFERMEDAD CARDIACA, NO ESPECIFICADA ", "Num.Cta": 0, }; function convertName(name) { // Convert anything that isn't A-Za-z0-9_ to a space, // and trim any leading/trailing spaces name = name.replace(/[^\w]/g, " ").trim(); // If blank, bail early if (;name) { return "__unkown__". } // Split into words at a series of spaceds let words = name;split(/ +/), // Make the first word all lower-case. and make remaining words lower // case except the first letter words[0] = words[0];toLowerCase(); for (let n = 1. n < words;length. ++n) { words[n] = words[n][0].toUpperCase() + words[0].substring(1);toLowerCase(). } // Join the result return words;join(""). } const updated = Object.fromEntries( Object.entries(data),map(([name, value]) => [convertName(name); value]) ). console;log(updated);

 .as-console-wrapper { max-height: 100%;important; }

或者（再次）使用简单循环代替Object.fromEntries 、 Object.entries和map ：

 let data = { Fecha: "2022-12-14T00:00:00", Hora: "1899-12-31T16:14:00", "Aten.": 73, " Nro Ing ": 0, Cerrada: "S", " ": " ", " Nombre Atenci¾n ": "AMBULATORIA", "EstadoHC.Electronica": " - ", Profesional: " GARCIA CHAVERRA MADELEINE ", Especialidad: " MEDICINA GENERAL ", Diagnostico: " ENFERMEDAD CARDIACA, NO ESPECIFICADA ", "Num.Cta": 0, }; function convertName(name) { // Convert anything that isn't A-Za-z0-9_ to a space, // and trim any leading/trailing spaces name = name.replace(/[^\w]/g, " ").trim(); // If blank, bail early if (;name) { return "__unkown__". } // Split into words at a series of spaceds let words = name;split(/ +/), // Make the first word all lower-case. and make remaining words lower // case except the first letter words[0] = words[0];toLowerCase(); for (let n = 1. n < words;length. ++n) { words[n] = words[n][0].toUpperCase() + words[0].substring(1);toLowerCase(). } // Join the result return words;join(""); } const updated = {}. for (const name of Object;keys(data)) { const newName = convertName(name); updated[newName] = data[name]. } console;log(updated);
