将从 sql 适配器返回的结果集分配给全局变量及其用法

这是我的JS文件

window.$ = window.jQuery = WLJQ;
function wlCommonInit() {
}
$(document).ready(function(){
    $("#search").click(function(){
    GetMedicine();
    });

});
window.e='';
var univ;
function GetMedicine() {
    var medicine= $("#medicine").val();
    var location=$("#location").val();
    alert(medicine);
    var invocationData = {
        adapter : 'ATM',
        procedure : 'getMedicineDetails1',
        parameters: [medicine,location]
    };
    WL.Client.invokeProcedure(invocationData,{
        onSuccess : loadFeedsSuccess,
        onFailure : loadFeedsFailure
    });

}
function loadFeedsSuccess(result){
    window.e=result;
    univ=result.invocationResult.resultSet.length;
    WL.Logger.debug("loadsfeedssuccess");
 if (result.invocationResult.resultSet.length>0) 
    {
         var invocationData={
                    adapter : 'ATM',
                    procedure : 'checkCount',
                    parameters: []
            };
         WL.Client.invokeProcedure(invocationData,{onSuccess:countgreater});
         }
     else 
        {
        loadFeedsFailure1();
        }
}
function countgreater(result){
    if(result.invocationResult.resultSet.length>0)
        {
        alert("entered count greater");
        var c=result.invocationResult.resultSet[0].num;
        if(c>=0)
            {
    invocationData={
            adapter : 'ATM',
            procedure : 'getStoreDetails',
            parameters: [e[c].RegNo]
    };
 WL.Client.invokeProcedure(invocationData,{onSuccess:displayAgain});
            }
        else
            {
            invocationData2={
                    adapter : 'ATM',
                    procedure : 'deleteQuery',
                    parameters: []
            };
         WL.Client.invokeProcedure(invocationData2);
            }
}
}

适配器 JS

         var selectStatement = WL.Server.createSQLStatement("select * from medicine WHERE Name= ? ");

我想通过将结果集分配给全局变量"e"来分配在后续函数中返回给 loadFeedsuccess的结果集。我无法这样做。当我在阅读e[c]时。RegNo 在 countgreater 函数中，它显示错误无法从未定义读取 RegNo。有没有办法这样做
