Question

我正在使用对Web服务的AJAX调用来检索服务调用列表。我需要遍历Web服务返回的每个服务调用并将其插入到SQLite表中。我正在努力解决循环中的时间问题。例如，如果有两个服务调用，则会在表中插入两行，但这两行都是第二次调用的数据。我已经尝试移动我的变量声明和值赋值，如果它们在事务中，那么所有字段都返回undefined。在交易之外，所有行都作为最后一条记录插入。

$.ajax({
    type: "POST",
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    url: "MyService.asmx/GetCalls",
    data: '{ user:"' +  user +'"}',
    success: function (data) {
        saveCalls(data.d);
    },
    error: function (xhr) {
        var err = eval("(" + xhr.responseText + ")");
        alert("Retrieve Calls: " + err.Message);
    }
});

function saveCalls(result) {
   var insertString = "Insert Into Calls Values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

   var call, po, adrsCode, status, dispDate, dispTime, desc, customer, address, city, state, zip, phone, equipment, tracking, srvType, statDesc;

   $.each(result, function () {
       call = this.CallNumber;
       po = this.PoNumber;
       adrsCode = this.AdrsCode;
       status = this.Status;
       dispDate = this.DispatchedDate;
       dispTime = this.DispatchedTime;
       desc = this.Description;
       customer = this.Customer;
       address = this.Address;
       city = this.City;
       state = this.State;
       zip = this.Zip;
       phone = this.Phone;
       equipment = this.Equipment;
       tracking = this.Tracking;
       srvType = this.SrvType;
       statDesc = this.StatDesc;
       db.transaction(function (tx) {

          tx.executeSql(insertString, [call, po, adrsCode, status, dispDate, dispTime, desc, customer, address,
            city, state, zip, phone, equipment, tracking, srvType, statDesc],
            onSqlSuccess, onSqlError);

    });
});

}

编辑：适用于具有相同问题的人的代码：

function saveCalls(result) {
   var insertString = "Insert Into Calls(CallNumber, PoNumber, AdrsCode, SrvStat, DispatchDate, DispatchTime, SvcDescription, CustNmbr, Address, "
            + "City, State, Zip, Phone, Equipment, Tracking, SrvType, StatDesc) ";

   $.each(result, function () {

       insertString = insertString + "Select '{0}' as CallNumber,'{1}' as PoNumber,'{2}' as AdrsCode,'{3}' as SrvStat,'{4}' as DispatchDate,'{5}' as DispatchTime,'{6}' as SvcDescription,'{7}' as CustNmbr,'{8}' as Address,'{9}' as City,'{10}' as State,'{11}' as Zip,'{12}' as Phone,'{13}' as Equipment,'{14}' as Tracking,'{15}' as SrvType,'{16}' as StatDesc Union "
                    .format(this.CallNumber, this.PoNumber, this.AdrsCode, this.Status, this.DispatchedDate, this.DispatchedTime,
                        this.Description, this.Customer, this.Address, this.City, this.State, this.Zip, this.Phone, this.Equipment, 
                        this.Tracking, this.SrvType, this.StatDesc);

   });

   db.transaction(function(tx) {
      tx.executeSql(insertString.substring(0, insertString.length - 6), [],
        onSqlSuccess, onSqlError);
   });

}
