javascript - 将参数传递给适配器时出现问题

Question

我有一个登录表单，其中包含用户名和密码。当用户点击提交按钮时，调用以下js函数。

function getGeoCode(){
    var para=[$('#usernameInputField').val()];
    alert("from sql adapter"+para);

    var id = {username : para };
    var invocationData = {
        adapter: "GDMSDbAdaptor",
        procedure: "getGeoCode",
        parameters: [id]
    };
    alert("before adapter proc call");

    WL.Client.invokeProcedure(invocationData, {
        onSuccess: getMessage,
        onFailure: getMessageOnfailure
    });
    alert("after adapter proc call");
}

下面的适配器代码在上面的函数之后执行

var procedureStatement = WL.Server.createSQLStatement("SELECT DISP_NUMBER,DISP_STATUS,DISP_CREATE_DATE,CUST_CONT_NAME,DISP_RES_OWNER,DISP_MANAGER FROM GDMW.DISPUTE WHERE DISP_RES_OWNER IN (SELECT USER_CNUM FROM GDMW.USER_ACC_PROFILE WHERE USER_EMAIL=?)");

function getGeoCode(data) { 
    var email=data.username; 

    WL.Logger.info("In getGeoCode method"+email);
    return WL.Server.invokeSQLStatement({
        preparedStatement : procedureStatement,
        parameters : [email]
    });
}

运行上述代码时出现以下错误

[ERROR ] FWLSE0099E: An error occurred while invoking procedure [project GDMSLoginApp]GDMSDbAdaptor/getGeoCodeFWLSE0100E: parameters: [project GDMSLoginApp] TypeError: Cannot find default value for object. (C%3A%5Cnewworkspaceworklight%5CGDMSLoginApp%5Cadapters%5CGDMSDbAdaptor/GDMSDbAdaptor-impl.js#22) FWLSE0101E: Caused by: [project GDMSLoginApp]nullorg.mozilla.javascript.EcmaError: TypeError: Cannot find default value for object. (C%3A%5Cnewworkspaceworklight%5CGDMSLoginApp%5Cadapters%5CGDMSDbAdaptor/GDMSDbAdaptor-impl.js#22)

但是当我硬编码如下参数(电子邮件 ID)时它工作正常:

function getGeoCode(){
    var para=[$('#usernameInputField').val()];
    alert("from sql adapter"+para);

    var id = {username : 'some@email.address' };
    var invocationData = {
        adapter: "GDMSDbAdaptor",
        procedure: "getGeoCode",
        parameters: [id]
    };

    alert("before adapter proc call");
    WL.Client.invokeProcedure(invocationData, {
        onSuccess: getMessage,
        onFailure: getMessageOnfailure
    });
    alert("after adapter proc call");
}

这与单引号有关吗？

我的第一个猜测是发生这种情况是因为您使用了括号:

var para=[$('#usernameInputField').val()];

当你不应该:

var para=$('#usernameInputField').val();

你也可以这样做:

var id = {username : $('#usernameInputField').val() };
