将文本输入值传递给IBM Worklight适配器

Question

1. 以下代码是否接受来自客户端的值并传递给适配器？
2. 我的JS函数会验证db？
中是否存在用户名和密码

HTML

<form action="index.html" onsubmit="return(login())">
    UserName:<input type="text" name="uname" id="username"><br>
    Password:<input type="password" name="pass" id="password"><br>
    <input type="submit" value="Login">
</form>

的JavaScript

function login() {
    var invocationData = {
        adapter : 'sq',
        procedure : "validateLogin",
        parameters : [$('#username').val(),$('#password').val()]
    };

    var options = {
        onSuccess : success,
        onFailure : failure
    };

    WL.Client.invokeProcedure(invocationData, options);
}

function success() {
    var allNames = new String();
    var allpass = new String();

    for (var i = 0; i < response.invocationResult.resultSet.length; i++) {
        allNames+= response.invocationResult.resultSet[i].name;
        allpass+= response.invocationResult.resultSet[i].pass;
    }

    var a=new String();
    var b=new String();
    a=JSON.stringify(allNames);
    b=JSON.stringify(allpass);

    if (a==$('#username').val() && b==$('#password').val() ){
        return true;
    } else {
        return false;
    }
}

function failure() {
    return false;
}

适配器程序

var query = WL.Server.createSQLStatement(
    "select name,pass from userreg where name=? and pass=?");

function validateLogin(username,password) {
    return WL.Server.invokeSQLStatement({
        preparedStatement : query,
        parameters : [username,password]
    });
}

Answer 1

<强> HTML：

<form id="frmId" onsubmit="return(login())">
    UserName:<input type="text" name="uname" id="username"><br>
    Password:<input type="password" name="pass" id="password"><br>
    <input type="submit" value="Login">
</form>

成功功能：

function success() {
    var allNames = new String();
    var allpass = new String();

    for (var i = 0; i < response.invocationResult.resultSet.length; i++) {
        allNames+= response.invocationResult.resultSet[i].name;
        allpass+= response.invocationResult.resultSet[i].pass;
    }

    var a=new String();
    var b=new String();
    a=JSON.stringify(allNames);
    b=JSON.stringify(allpass);

    if (a==$('#username').val() && b==$('#password').val() ){
        $("#frmId").attr('action', URL of the page you wants to redirect to);
        return true;
    } else {
        return false;
    }
}
