Question

我有两个页面，Login.php和LoginCheck.php。我正在验证LoginCheck.php中凭据的正确和错误方案。我想在不正确的凭据上显示Login.php中的模态。但是，我不知道该怎么做。

我尝试过警告，它只在控制台中显示消息

我在考虑如何将else的{{1}}重定向到LoginCheck.php的功能，Login.php显示所有其他模态，但不知道该怎么做< / LI>

的login.php

function openUserProfileModal ()
{
    var modal = document.getElementById('modal');
    modal.style.display = "none";
}

function validateLogin()
{
    var modal = document.getElementById('modal');
    var errorDescription = document.getElementById('errorDescription');
    var processing = document.getElementById('processingLogin');
    var Email = document.getElementById('Email').value;
    var pass = document.getElementById('Password').value;

    if(Email == "" && pass == "")
    {
        modal.style.display="block";
        errorDescription.innerHTML = "Please enter your email address and password";
    }
    else if (Email != "" && pass == "") 
    {
        modal.style.display="block";
        errorDescription.innerHTML = "Please enter your password";
    }
    else if (Email == "" && pass != "") 
    {
        modal.style.display="block";
        errorDescription.innerHTML = "Please enter your email address";
    }
    else if (Email == null && pass == null) 
    {
        modal.style.display="block";
        errorDescription.innerHTML = "Please enter your email address and password";
    }
    else
    {

        //processing.style.display = "block";

        // validation for correct and incorrect credentails
        ajax.sender_data_json_by_url_callback('LoginCheck.php', 
        {
            act: 'login',
            email: Email,                                       
            pass: pass
        });
        //this.check("LoginFornmDiv")

请帮忙

感谢您的回复。我首先学习了AJAX，然后使用它，比如AJAX调用。将用户从Login.php发送到LoginCheck.php并使用AJAX在else语句中显示错误，如果这是有意义的。

显示错误用户凭据的模式
