如何从位于EmployerDetails内的身份获取Identity值。我已尝试过以下但如果条件：

它永远不会进入

{"EmployerDetails":{"Distance":30,"EmpLatitude":51.3353899,"EmpLongitude":-0.742856,"EmpNo":39424,"Insitution":null,"PlaceName":"Camberley","TalentPoolLicences":[{"Membership":[{"Identity":39424,"Name":"Weydon Secondary School"}],"TalentPoolType":1},{"Membership":[{"Identity":2,"Name":"North East Hampshire"},{"Identity":4,"Name":"Surrey"},{"Identity":8,"Name":"Surrey"}],"TalentPoolType":3}]},"FacetFilters":{"LastActivity":0,"LocationFilterType":1,"fullorparttime_pex":null,"religion":null,"soughtphase_swk":null,"soughtrole_swk":null,"soughtsubject_swk":null},"LookingFor":null,"OrderBy":null,"PageIndex":1,"PageSize":40}

对此有任何帮助吗？

Answer 1

您是否尝试将其转换为json对象然后获取值？

Answer 2

当您首先搜索嵌套密钥时，您需要抓取该对象，并且还需要使用JSON.parse将其解析为JSON，然后您可以像我们在普通javascript对象上一样继续

localStorage.getItem('signup-prefs')

这给了我一个包含我的对象的字符串

""name":"google","oauth_version":"2.0","oauth_server":"https://accounts.google.com/o/oauth2/auth","openid":"","username":""}"

解析后我们可以得到对象，现在我们可以找到所需的属性。

JSON.parse(localStorage.getItem('signup-prefs'))

Object {name: "google", oauth_version: "2.0", oauth_server: "https://accounts.google.com/o/oauth2/auth", openid: "", username: ""}

来你的问题

让我们说你的员工信息是这样的，我没有在这里显示所有字段。

var empData = {"EmployerDetails":Distance":30,"EmpLatitude":51.33538}}

然后你就像这样设置键

localstorage.setItem('empData', JSON.stringify(empData))

现在通过键将字符串对象解析为Json并从对象循环中找到所需的键以获得结果。我没有测试它但我相信它会起作用。如果没有，请告诉我。

for (var i = 0; i < localStorage.length; i++) {
     if (localStorage.key(i) === 'empData') {

        // Parse the string to json

         var empData = JSON.parse(localStorage.getItem('empData'));

        // get all the keys
         var keys = Object.keys(empData);

         for (var idx = 0; idx < keys.length; idx++) {
            // find the desired key here
             if (keys[idx] == 'EmployeeDetails') {
                 var empDetails = empData[keys[idx]]
             }
         }
     }
 }

您的代码的一个重要事项是这个语句localStorage.key(i)) === 'EmployerDetails'返回true或false，并且这样写 if(localStorage.getItem(localStorage.key(i)) === 'EmployerDetails')永远不会被执行，因为你没有任何具有该名称的密钥（实际上我们绝不应该使用关键字作为密钥）。
