我的点击第二次不起作用

My onclick not working the second time

本文关键字：不起作用第二次我的更新时间：2023-09-26

每当用户单击注册或注册时，我都试图更改表单中的属性。因此，表单将相应更改，但是一旦用户单击注册，他们就无法再单击登录。

 <?php
 session_start();

    if(isset($_POST['submit'])) {
        include_once("php/config/database.php"); 
        $Email = strip_tags($_POST['Email']);
        $dbPassword = strip_tags($_POST['Password']);
        $Email = stripslashes($Email);
        $dbPassword = stripslashes($dbPassword);
        $Email = mysqli_real_escape_string($conn, $Email);
        $dbPassword = mysqli_real_escape_string($conn, $dbPassword);

        $sql = ("SELECT * FROM 'Users' WHERE Email='$Email' AND Password='$dbPassword' LIMIT 1");
        $query = mysqli_query($conn, $sql);
        $row = mysqli_fetch_array($query);
        $UserID = $row['UserID'];
        $dbpass = $row['Password'];
        if($dbPassword == $dbpass) {
            $_SESSION['Email'] = $Email;
            $_SESSION['UserID'] = $UserID;
            header("Location: account.php");
        } 
        else 
        {
            echo "You didn't enter the correct details!";
        }
    } 

?>

JS文件

function register(){
var cont = 0;   
     cont++;
        if(cont==1){
            $('.box').animate({height:'600px'}, 550);
            $('.show').css('display','block');
            $('#logintoregister').text('Register');
            $('#buttonlogintoregister').text('Register');
            $('#plogintoregister').text("Sei gia' registrato?");
            $('#textchange').text('Login');
            $('#search-theme-form').removeAttr("action").attr("action", "signup_destination.php");

        }
        else
        {
            $('.show').css('display','none');
            $('.box').animate({height:'365px'}, 550);
            $('#logintoregister').text('Login');
            $('#buttonlogintoregister').text('Login');
            $('#plogintoregister').text("Non sei iscritto?");
            $('#textchange').text('Register');
            $('#search-theme-form').removeAttr("action").attr("action", "index.php");

            cont = 0;

        }
}

每次函数运行时，您都会不断重置 cont var，

var cont = 0;

因此，您将始终输入if的第一部分。

从函数中取出变量计数：

var cont = 0;
function register(){
..
..
.
}

这样，他就不会在每次函数运行到 0 时重置，其余的应该可以工作。
