如何在 Laravel 中使用 Ajax 单击时验证模态形式

Question

我在 Laravel 项目中有一个用于登录的模式表单。当我输入虚假数据并单击按钮 "Log in" 时，页面刷新和模式正在关闭。只有当我再次打开模态时，我才能看到错误。它不是用户友好的。我想用 Ajax 验证模式，如果出现问题而不刷新页面

则显示错误

这是我的模态

试试这个

You need to some custom changes yourself in code.

$('#frmLogin').on('submit', function (event) {
    event.preventDefault();
    var formData = $(this).serialize();
    $.ajax({
        type: 'POST',
        url: '/login',
        data: formData,
        success: function (res) {
            console.log(res); // get resposnse from controller in json
            if (res.emailError) {
                $('.error-email').show().text(res.errorMsg);
            } else {
                $('.error-email').hide();
            }

            if (res.passwordError) {
                $('.error-password').text(res.errorMsg);
            } else {
                $('.error-password').hide();
            }
        },
        error: function (data) {
            alert(data);
        }
    });
});
