使用Eval（）将字符串转换为Object失败

Question

我有一个像这样的字符串

{
  recid: 1,
  QualHeadID: "1",
  Nomor: "1",
  Qualification: "Qualification",
  DetailQualification: "Detail Qualification",
  Unit: "Percentage",
  Target: "90.00 %",
  Actual: "90.00 %",
  Percentage: "100.00 %",
  CategoryWeight: "60.00 %",
  KpiScore: "60.00 %",
  Category: "Revenue",
  w2ui: {
    children: [{
      recid: 1007,
      QualHeadID: "1",
      Nomor: "1",
      DetailQualification: "Description"
    }]
  }
}, {
  recid: 2,
  QualHeadID: "1",
  Nomor: "2",
  Qualification: "Qualification 2",
  DetailQualification: "Detail Qualification 2",
  Unit: "Percentage",
  Target: "80.00 %",
  Actual: "89.00 %",
  Percentage: "111.25 %",
  CategoryWeight: "10.00 %",
  KpiScore: "11.13 %",
  Category: "Quality",
  w2ui: {
    children: [{
      recid: 1008,
      QualHeadID: "1",
      Nomor: "2",
      DetailQualification: "Description 2"
    }]
  }
}, {
  recid: 3,
  QualHeadID: "1",
  Nomor: "3",
  Qualification: "Qualification 3",
  DetailQualification: "Detail Qualification 3",
  Unit: "Percentage",
  Target: "85.00 %",
  Actual: "99.00 %",
  Percentage: "116.47 %",
  CategoryWeight: "30.00 %",
  KpiScore: "34.94 %",
  Category: "Internal",
  w2ui: {
    children: []
  }
}

当我尝试使用Eval（）

将其转换为Object时，它可以正常工作

 var jsonQual = eval("[" + $("#lblQualification1").text() + "]");

然而，我尝试转换此字符串的方式相同

{
  recid: 5,
  QualHeadID: "4",
  Nomor: "4",
  Qualification: "Competency - External",
  DetailQualification: "80% of customer score top-three-boxes score",
  Unit: "Percentage",
  Target: "70.00 %",
  Actual: "60.00 %",
  Percentage: "85.71 %",
  CategoryWeight: "50.00 %",
  KpiScore: "42.86 %",
  Category: "Quality",
  w2ui: {
    children: [{
      recid: 1011,
      QualHeadID: "4",
      Nomor: "4",
      DetailQualification: "80% dari total customer/company mengisi nilai 8,9 atau 10 dari range (1-10), di Nilai Total Penilaian Kepuasan Pelanggan (ex. Total customer selama periode review ada 10 cust, harus paling tidak 8 customer yang memberi nilai minimal 8) Apabila ada 7 orang memberi nilai 10, tetap ada 3 orang memberi nilai dibawah 8, dianggap tidak achieve Apabila dalam 1 company ada lebih dari 1 orang yang di survey, nilai dari company itu adalah rata2 nilai dari tiap orang yang disurvey Untuk yg Customer nya hanya 1 company, total customer berarti jumlah orang yang di survey dari company tsb"
    }]
  }
}, {
  recid: 6,
  QualHeadID: "4",
  Nomor: "5",
  Qualification: "Scoring Daily Activity",
  DetailQualification: "90% submitted on time",
  Unit: "Percentage",
  Target: "80.00 %",
  Actual: "60.00 %",
  Percentage: "75.00 %",
  CategoryWeight: "25.00 %",
  KpiScore: "18.75 %",
  Category: "Internal",
  w2ui: {
    children: [{
      recid: 1012,
      QualHeadID: "4",
      Nomor: "5",
      DetailQualification: "Each engineer must submit billable daily activity to timesheet application every Tuesday 10 AM and Friday 4 PM"
    }]
  }
}, {
  recid: 7,
  QualHeadID: "4",
  Nomor: "6",
  Qualification: "Self Development ",
  DetailQualification: "80% attending to workshop & English Course ",
  Unit: "Percentage",
  Target: "80.00 %",
  Actual: "90.00 %",
  Percentage: "112.50 %",
  CategoryWeight: "25.00 %",
  KpiScore: "28.13 %",
  Category: "Internal",
  w2ui: {
    children: [{
      recid: 1013,
      QualHeadID: "4",
      Nomor: "6",
      DetailQualification: "This qualification divided into two category. 2,5% for attending workshop and 2.5% for final score taken from English Course. If there is no workshop then 5% for English course"
    }]
  }
}

它不起作用

我的字符串怎么了？我从eval方法背叛的任何规则？ 提前谢谢!!
