json 怎么存数组里的单个值。求大神帮帮忙！

[zmgst]

function querySchoolTermId(){

var data = {
'evaluateModel.studentId':studentId,
};
ajaxSubmitData("evaluateAjax/evaluate!querySchoolTermId.action", data, function(rtnData){
var v=[];
v=rtnData.schoolTermId;
for(var i=0;i<v.length;i++)
{

var v1=v[i];
var data = {
'evaluateModel.studentId':studentId,
'evaluateModel.schoolTermId':v1
};
alert(v1);
ajaxSubmitData("evaluateAjax/evaluate!querySchoolTermName.action", data, function(rtnData){
schoolTermFill(rtnData);
});
ajaxSubmitData("evaluateAjax/evaluate!rtnSubjectExamAverageScoreList.action", data, function(rtnData){
//var studentList = rtnData.studentList;

createScoreRadarChart(rtnData);

subjectLevelDescFill(rtnData);

});
}
});
}

现在V里已经有值了，我怎么往data里写的时候只写一个出来
