在javascript中解析json字符串时出错

Question

我在我的asp.net项目中第一次在Javascript中使用JSON.我是新手.我已在页面加载时成功创建了一个JSON字符串,并将其存储在隐藏字段中.现在,在Javascript中,当我尝试eval或解析该字符串时,它不会解析它.

请帮忙.我是这样做的:

var jsonText = $("#hiddenJson").val();

var jsonObject = JSON.parse(jsonText);       

//var jsonObject = eval("(" + jsonText + ")");

alert(jsonObject.user[0].Gender);

//---- alert gives [object Object]

//------- value of jsonText is

"[ { "user": [ { "Gender": "M", "Minage": "28", "Maxage": "24", "MaritalStatusId": "2,3", "ChildrenPreferencesId": "0", "PersonalValueId": "1", "MinHeight": "6", "MaxHeight": "1", "BodyTypeId": "0", "ComplexionId": "0", "HealthAttributeId": "1", "SpecialCaseId": "1", "ReligionId": "3,5", "CasteId": "1,6", "MotherTongueId": "", "QualificationLevelId": "2,3", "QualificationFieldId": "", "WorkingWithId": "4,5", "ProfessionArea": "3,4", "WorkingAsId": "3,4", "IncomeId": "3", "DietId": "0", "SmokeId": "1", "DrinkId": "2", "CountryId": "4,5", "ResidencyId": "", "PartnerDescription": "" }] } ]"

如果你对json对象的成员使用双引号,那么将整个字符串放在单引号中,比如

var jsonText = '[ { "user": [ { "Gender": "M", "Minage": "28", "Maxage": "24", "MaritalStatusId": "2,3", "ChildrenPreferencesId": "0", "PersonalValueId": "1", "MinHeight": "6", "MaxHeight": "1", "BodyTypeId": "0", "ComplexionId": "0", "SpecialCaseId": "1", "ReligionId": "3,5" }] } ]'
