Question

我使用Materialise CSS框架，表单验证无效。

电子邮件验证工作正常：

<div class="row">
        <div class="input-field col s12 m5 offset-m3">
            <i class="material-icons prefix">email</i>
            <input type="email" id="input_email" name="email" class="validate" />
            <label for="input_email" data-error="Please enter a valid email address">Email</label>
        </div>
    </div>

然而，当涉及到一个简单的必填字段时，验证不起作用......

<div class="row">
        <div class="input-field col s12 m5 offset-m3">
            <i class="material-icons prefix">account_circle</i>
            <input type="text" id="input_name" data-error="Please enter your name" name="input_name" class="validate" required="required" aria-required="true"/>
                <label for="input_name">Name</label>
        </div>
</div>

如另一篇文章所述，

materialize best practice validate empty field

我添加了必需的和aria-required属性（必需=＆＃34;必需＆＃34;以及必需=＆＃34;＆＃34;值[我不知道为什么会这么说，据我所知，前者是正确的]）。但是，除了电子邮件字段之外，验证仍然没有做任何事情......

我做错了什么？

您可以使用以下代码覆盖validate_field函数

https://codepen.io/anon/pen/QgqLxE

$(document).ready(function() {
    window.validate_field = function(object) {
        var hasLength = object.attr('data-length') !== undefined;
        var lenAttr = parseInt(object.attr('data-length'));
        var len = object.val().length;
        if (object.val().length === 0 && object[0].validity.badInput === false && !object.is(':required')) {
            if (object.hasClass('validate')) {
                object.removeClass('valid');
                object.removeClass('invalid');
            }
        } else {
            if (object.hasClass('validate')) {
                // Check for character counter attributes
                if ((object.is(':valid') && hasLength && (len <= lenAttr)) || (object.is(':valid') && !hasLength)) {
                    object.removeClass('invalid');
                    object.addClass('valid');
                } else {
                    object.removeClass('valid');
                    object.addClass('invalid');
                }
            }
        }
    };
});
