我创建了一个简单的MDC卡,上面带有一些MDC文本字段按钮。但是,文本框不能正确呈现。从下图可以看到,右上角和左上角都有空隙。下面是我的代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Material Card Example</title>

<link rel="stylesheet" href="https://unpkg.com/material-components-web/dist/material-components-web.min.css">
</head>
<body>
<div class="mdc-card">
<div class="">
<div class="card-header">
<div class="mdc-card__actions">
<div class="mdc-text-field mdc-text-field--box username">
<input type="text" class="text-field--outlined" id="username-input" name="username" required>
<label class="mdc-floating-label" for="username-input">Email</label>
<div class="mdc-line-ripple"></div>
</div>
</div>
<div class="mdc-card__actions">
<div class="mdc-text-field mdc-text-field--box password">
<input type="password" class="text-field--outlined" id="password-input" name="password" required minlength="8">
<label class="mdc-floating-label" for="password-input">Password</label>
<div class="mdc-line-ripple"></div>
</div>
</div>
</div>
<script src="https://unpkg.com/material-components-web/dist/material-components-web.min.js"></script>
</body>
</html>
答案 0 :(得分:1)
您的代码有几个问题:
mdc-text-field__input
类。text-field--outlined
类,但这很可能什么也没做。如果要使用概述的变体,则也可以在documentation中找到正确的标记。请注意,它具有比填充(框)变体更多的标记。我也建议您不要以mdc-card__actions
的方式使用它,因为它实际上是打算在卡的底部使用(每张卡只能使用一次)。
以下是适用于填充(框)变体的标记示例:
<div class="mdc-card">
<div>
<div class="mdc-text-field mdc-text-field--box username">
<input class="mdc-text-field__input" type="text" id="username-input" name="username" required>
<label class="mdc-floating-label" for="username-input">Email</label>
<div class="mdc-line-ripple"></div>
</div>
</div>
<div>
<div class="mdc-text-field mdc-text-field--box password">
<input class="mdc-text-field__input" type="password" id="password-input" name="password" required minlength="8">
<label class="mdc-floating-label" for="password-input">Password</label>
<div class="mdc-line-ripple"></div>
</div>
</div>
</div>
这是JS来实例化两个文本字段(或其中任意数量)的JS:
[].forEach.call(document.querySelectorAll('.mdc-text-field'), function(el) {
mdc.textField.MDCTextField.attachTo(el);
});
