在我的带有codeigniter的引导模型表单上,如果输入的用户名不正确,它将显示消息。 但当我点击按钮时,即使显示验证错误,引导模式也会消失

目标:我希望能够做到的是,如果任何表单验证为真,则不会关闭引导模式,但如果表单验证正常,则让我提交

如果表单验证出错,如何防止引导模式关闭

我试过使用
e.preventDefault()不走运

错误验证
是CI提供的一项功能

提交页面时,只能使用code igniter的错误验证,因此,由于页面正在提交,引导模式将自动关闭

如果您想在模式上执行表单验证,最好使用
AJAX

如果要在打开的表单上方显示错误消息, 只需创建一个空白div,如:

<div class='error_msg'>

</div>

“验证”后缺少一个结束括号css声明:
bootstrap模式仍然会消失,尽管已经修复。您有示例吗,因为我希望表单上的表单验证消息仍然显示在表单打开的正上方。我添加了我的控制器删除函数数据中的内容:在ajax中?只需将字段信息作为json传递,并在php文件中验证它。我还有在包含表单的模式中显示错误时也会出现同样的问题。
<div class='error_msg'>

</div>
$(function(){

$('#form_id').submit(function(event){
event.preventDefault();
var custemail = $('#email_id').val();
var custname = $('#name').val();

$.ajax({
        type: 'POST',
        url: your controller path,
        data: {
         'name': custname,
         'email': custemail

        },
        dataType: 'html',
        success: function(results){
             if(something not as you expected){
              $('.error_msg').html('error msg');
              return false;
             }
        }
  });


});

});
