如何通过javascript访问JSON数据

Question

我想访问单选按钮（性别字段）中的jsongrid值，而不应用html.I尝试了简单的JavaScript函数，它在UI中正常工作，但通过html输入来值但我希望值来从jsongrid.Plz帮我..

这是JavaScript代码

<script type="text/javascript"> 
    $j.ajax({ 
     url:"UserGender", 
     type: "GET", 
     data: datasourses, 
     dataType: "json", 
     success: function (data){ 
      $.each(data, function(i, selectedItem) { 
       alert("paramValue: " + selectedItem.paramValue + ", paramCode: " +  
       data.selectedItem.paramCode); 
      }); 
     }  
    }); 
</script> 

这是HTML

<input type="radio" name="Female" > 
<input type="radio" name="Male" > 

的Json代码

{ 
    "jsonWrapperforGrid": { 
     "page": "1", 
     "total": "2", 
     "rows": [ 
      { 
       "tenantId": 0, 
       "paramType": "UserGender", 
       "paramCode": "F", 
       "langCode": "en", 
       "paramValue": "Female" 
      }, 
      { 
       "tenantId": 0, 
       "paramType": "UserGender", 
       "paramCode": "M", 
       "langCode": "en", 
       "paramValue": "Male", 
       "paramBlob": "" 
      } 
     ] 
    } 
} 

在此先感谢

$.each(data.jsonWrapperforGrid.rows, function() { 
    alert("paramValue: " + this.paramValue + ", paramCode: " + this.paramCode); 
});
