根據 object 鍵 substring 對 JavaScript 中的對象數組進行排序

Question

我有一系列對象

[
  {
    Severity: "<span class='tableActive'></span>",
    Name: 'U3B',
    'U1A_Shift SCM: UPTT-Pressure (Bara)': '-',
    'U1A_Shift SCM: DPTT-Pressure (Bara)': '-',
    'U3B SCM: APTT-Pressure (Bara)': '3510.00',
    'U3B SCM: UPTT-Pressure (Bara)': '3413.00',
    'U1B SCM: DPTT-Pressure (Bara)': '-',
    'U1B SCM: UPTT-Pressure (Bara)': '-',
    'U3B SCM: DPTT-Pressure (Bara)': '740.00',
    'U1A_Shift SCM: UPTT-Temp (DegC)': '-',
    'U1A_Shift SCM: DPTT-Temp (DegC)': '-',
    'U3B SCM: APTT-Temp (DegC)': '1565.00',
    'U3B SCM: UPTT-Temp (DegC)': '2654.00',
    'U1B SCM: DPTT-Temp (DegC)': '-',
    'U1B SCM: UPTT-Temp (DegC)': '-',
    'U3B SCM: DPTT-Temp (DegC)': '3159.00',
    'U1B SCM: PCV-CHOKE status - Control position': '-',
    'U3B SCM: PCV-CHOKE status - Control position': '-',
    'U1A_Shift SCM: PCV-CHOKE status - Control position': '-',
    Alarms: 0,
    Advisories: 0,
    __row_index: 0,
  },
]

因此 output 應該是

[
  {
    Severity: "<span class='tableActive'></span>",
    Name: 'U3B',
    'U1A_Shift SCM: UPTT-Pressure (Bara)': '-',    // grouped by UPTT-Pressure (Bara)
    'U3B SCM: UPTT-Pressure (Bara)': '3413.00',
    'U1B SCM: UPTT-Pressure (Bara)': '-',
    'U1A_Shift SCM: DPTT-Pressure (Bara)': '-',    //grouped by DPTT-Pressure (Bara)
    'U1B SCM: DPTT-Pressure (Bara)': '-',
    'U3B SCM: DPTT-Pressure (Bara)': '740.00',
    'U3B SCM: APTT-Pressure (Bara)': '3510.00', // grouped by APTT-Pressure (Bara)
    'U1A_Shift SCM: UPTT-Temp (DegC)': '-', // grouped by UPTT-Temp (DegC)
    'U3B SCM: UPTT-Temp (DegC)': '2654.00',
    'U1B SCM: UPTT-Temp (DegC)': '-',
    'U1A_Shift SCM: DPTT-Temp (DegC)': '-', // grouped by DPTT-Temp (DegC)
    'U1B SCM: DPTT-Temp (DegC)': '-',
    'U3B SCM: DPTT-Temp (DegC)': '3159.00',
    'U3B SCM: APTT-Temp (DegC)': '1565.00', // grouped by APTT-Temp (DegC)
    'U1B SCM: PCV-CHOKE status - Control position': '-', // grouped by PCV-CHOKE status - Control position
    'U3B SCM: PCV-CHOKE status - Control position': '-',
    'U1A_Shift SCM: PCV-CHOKE status - Control position': '-',
    Alarms: 0,
    Advisories: 0,
    __row_index: 0,
  }
]

我需要根據“：”之后的鍵名對這個對象數組進行排序，例如：APTT-Temp (DegC)

我只列出一個 object 我收到了對象數組

我需要對這個對象數組進行排序，基本上按“：”（冒號）之后的鍵值分組

您只需稍微修改以下 SO 問題的答案，以便它比較（例如整數）值而不是鍵Sorting a array of objects by object key 。 或者，您可以使用此 SO 問題的解決方案： 如何排序 function 在 JavaScript 中工作，以及比較 function

工作示例：

 var arr = [ { Severity: "<span class='tableActive'></span>", Name: 'U3B', 'U3B SCM: UPTT-Pressure (Bara)': '3413.00', 'U3B SCM: APTT-Temp (DegC)': '1565.00', 'U3B SCM: PCV-CHOKE status - Control position': '-', 'U1A_Shift SCM: PCV-CHOKE status - Control position': '-', Alarms: 0, Advisories: 0, __row_index: 0 }, { Severity: "<span class='tableActive'></span>", Name: 'U3B', 'U3B SCM: UPTT-Pressure (Bara)': '3413.00', 'U3B SCM: APTT-Temp (DegC)': '840.00', 'U3B SCM: PCV-CHOKE status - Control position': '-', 'U1A_Shift SCM: PCV-CHOKE status - Control position': '-', Alarms: 0, Advisories: 0, __row_index: 0 }, { Severity: "<span class='tableActive'></span>", Name: 'U3B', 'U3B SCM: UPTT-Pressure (Bara)': '3413.00', 'U3B SCM: APTT-Temp (DegC)': '1427.00', 'U3B SCM: PCV-CHOKE status - Control position': '-', 'U1A_Shift SCM: PCV-CHOKE status - Control position': '-', Alarms: 0, Advisories: 0, __row_index: 0 } ]; arr.sort( function(a, b) { const aValue = parseInt(a['U3B SCM: APTT-Temp (DegC)']); const bValue = parseInt(b['U3B SCM: APTT-Temp (DegC)']); return aValue - bValue; }); console.log(arr)
