Question

我有一个带有数据的json文件，我应该按以下格式加载到数组：

var jobs = [
  { ID: 'grt34hggdggf', Employer: 'A1', Title: 'tobi1', Location: 'Los Angeles, CA', Department: 'department', OpeningDate: '2012-12-26T01:29Z', ClosingDate: '2013-04-26T01:29Z', MinSalary: '30000', MaxSalary: '60000', Description: 'bla-gghrf-bla' },
  { ID: 'grt34hgwerwgf', Employer: 'A2', Title: 'tobi2', Location: 'Los Angeles, CA', Department: 'department', OpeningDate: '2012-12-26T01:29Z', ClosingDate: '2013-04-26T01:29Z', MinSalary: '30000', MaxSalary: '60000', Description: 'bla-gghrf-bla' }
];

所以，这种格式适合我并使用视图。哪种格式应该有我的json文件。我尝试以下方法：

{
    "jobs":[
  { "ID": "grt34hggdggf", "Employer": "A1", "Title": "tobi1", "Location": "Los Angeles, CA", "Department": "department", "OpeningDate": "2012-12-26T01:29Z", "ClosingDate": "2013-04-26T01:29Z", "MinSalary": "30000", "MaxSalary": "60000", "Description": "bla-gghrf-bla" },
  { "ID": "grt34hggdggf", "Employer": "A2", "Title": "tobi1", "Location": "Los Angeles, CA", "Department": "department", "OpeningDate": "2012-12-26T01:29Z", "ClosingDate": "2013-04-26T01:29Z", "MinSalary": "30000", "MaxSalary": "60000", "Description": "bla-gghrf-bla" }

  ]
}

但是当我尝试在视图中执行“forEach”时出现错误：

TypeError: F:\tmp\express-master\examples\ejs\views\result.html:5
    3| 
    4| <table>
 >> 5|   <% jobs.forEach(function(job){ %>
    6|     <tr>
    7|         <td>
    8|             <a href="/job/<%= job.ID %>"><%= job.Title %></a>

Object #<Object> has no method 'forEach'

所以，看起来，json文件的格式比预期的还要多。如何正确地做到这一点？

我在案例中找到了正确的格式：

[
  { "ID": "grt34hggdggf", "Employer": "A1", "Title": "tobi1", "Location": "Los Angeles, CA", "Department": "department", "OpeningDate": "2012-12-26T01:29Z", "ClosingDate": "2013-04-26T01:29Z", "MinSalary": "30000", "MaxSalary": "60000", "Description": "bla-gghrf-bla" },
  { "ID": "fgert", "Employer": "A2", "Title": "tobi2", "Location": "Los Angeles, CA", "Department": "department", "OpeningDate": "2012-12-26T01:29Z", "ClosingDate": "2013-04-26T01:29Z", "MinSalary": "30000", "MaxSalary": "60000", "Description": "bla11-ggh777rf-bla" }
]
