将文本输入值传递给IBM Worklight适配器

Pass text input value to IBM Worklight adapter

  1. 下面的代码会接受客户端的值并传递给适配器吗
  2. 如果数据库中存在用户名和密码，我的JS函数会验证吗

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>

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]
    });
}

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;
    }
}
