Question

我无法登录位于PC服务器的数据库。我使用Cordova / Phonegap。

那是我的代码。
HTML：

    <head>
        <title>Login Form Using jQuery - Demo Preview</title>
        <meta name="robots" content="noindex, nofollow">

    <body style="background-color: red;">
        <div class="container">
            <div class="main">
                <form class="form" method="post" action="#">
                    <h2>Create Login Form Using jQuery</h2>
                    <label>Email :</label>
                    <input type="text" name="demail" id="email">
                    <label>Password :</label>
                    <input type="password" name="password" id="password">
                    <input type="button" name="login" id="login" value="Login">
                </form>
            </div>
        </div>
    </body>
</html>

login.js：

$(document).ready(function () {
    $("#login").click(function () {
        var email = $("#email").val();
        var password = $("#password").val();

// Checking for blank fields.
        if (email === '' || password === '') {
            $('input[type="text"],input[type="password"]').css("border", "2px solid red");
            $('input[type="text"],input[type="password"]').css("box-shadow", "0 0 3px red");
            alert("Please fill all fields...!!!!!!");
        } else {
            $.post("http://192.168.0.110/login.php", {email1: email, password1: password},
            function (data) {

                if (data === 'Invalid Email.......') {
                    $('input[type="text"]').css({"border": "2px solid red", "box-shadow": "0 0 3px red"});
                    $('input[type="password"]').css({"border": "2px solid #00F5FF", "box-shadow": "0 0 5px #00F5FF"});
                    alert(data);
                } else if (data === 'Email or Password is wrong...!!!!') {
                    $('input[type="text"],input[type="password"]').css({"border": "2px solid red", "box-shadow": "0 0 3px red"});
                    alert(data);
                } else if (data === 'Successfully Logged in...') {
                    $("form")[0].reset();
                    $('input[type="text"],input[type="password"]').css({"border": "2px solid #00F5FF", "box-shadow": "0 0 5px #00F5FF"});
                    alert(data);
                } else {
                    alert(data);
                }
            });
        }
    });
});

login.php（在我的localhost上）

<?php
$connection = mysql_connect("localhost", "root", ""); // Establishing connection with server..
$db = mysql_select_db("college", $connection); // Selecting Database.
$email=$_POST['email1']; // Fetching Values from URL.
$password= sha1($_POST['password1']); // Password Encryption, If you like you can also leave sha1.
// check if e-mail address syntax is valid or not
$email = filter_var($email, FILTER_SANITIZE_EMAIL); // sanitizing email(Remove unexpected symbol like <,>,?,#,!, etc.)
if (!filter_var($email, FILTER_VALIDATE_EMAIL)){
echo "Invalid Email.......";
}else{
// Matching user input email and password with stored email and password in database.
$result = mysql_query("SELECT * FROM registration WHERE email='$email' AND password='$password'");
$data = mysql_num_rows($result);
if($data==1){
echo "Successfully Logged in...";
}else{
echo "Email or Password is wrong...!!!!";
}
}
mysql_close ($connection); // Connection Closed.
?>

当我点击登录按钮时，没有任何反应。我尝试添加一个警报，但它在$ .post（）中但没有显示。

任何想法的人？

提前致谢。：d

将此$.post替换为此

$.ajax({
        type: 'POST',
        url: 'http://192.168.0.110/login.php',
        data:{email1: email, password1: password},
        success: function(data) {
          alert("from server"+data);
        },
        error:function(err){
            alert("error"+JSON.stringify(err));
        }
      });

并跟踪error函数的输出，这将有助于我们找到错误的错误

使用cordova / phonegap连接到远程数据库
