成功引导验证后页面重定向而不使用php

Question

团队，

我正在尝试在表单验证成功后重定向。如果不成功，则必须在同一页面中；如果成功，则必须重定向其他页面

我在类验证代码之后添加了以下行

$(location).attr('href', 'data.html');

它正在重定向到下一页，但我没有看到任何错误消息我错过了一些验证。

这是我的全部代码。

$(function () {
'use strict'
$('#data_input').on('submit', function (event) {
    if (!event.target.checkValidity()) {
        event.preventDefault()
        event.stopPropagation()

    }
    $(this).addClass('was-validated')
    $(location).attr('href', 'data.html');
    return true;

});
$("#resetbtn").on("click", function (event) {
    event.preventDefault();
    $('#data_input')
        .trigger("reset")
        .removeClass('was-validated')
});
});

请让我知道我在这里做错了什么

Answer 1

在您的活动中提交。您使用验证 if 语句 (checkvalidity)。

$('#data_input').on('submit', function (event) {
**if (!event.target.checkValidity()) {**
    event.preventDefault()
    event.stopPropagation()

}
$(this).addClass('was-validated')
**$(location).attr('href', 'data.html');**
return true; ...

但无论它是否有效，您仍然会在之后执行位置重定向。 重定向应该放在 if 中，而不是在任何验证之前总是会被重定向。
