html - 让输入 type=text 看起来像 type=password

Question

tl;博士

我有一个输入type=text，我想用它来显示星星，就像type=password只使用 CSS 的输入一样。

---

基本上我有一个带有以下输入的表单：

<input type='text' value='hello' id='cake' />

我没有生成表单，我根本无法访问它的 HTML。但是，我确实可以访问应用于页面的 CSS。

我想要的是它的行为type=password，也就是说 - 为用户键入的内容而不是正在键入的实际文本显示星号。基本上，我希望这方面（用户输入的呈现）看起来像一个type=password字段。

由于这似乎只是一个演示问题，我认为必须有一种方法可以使用 CSS 来做到这一点，因为它在其职责范围内。但是 - 我还没有找到这样的方法。我必须支持 IE8+，但我宁愿有一个仅适用于现代浏览器的解决方案，而不是根本没有解决方案。防止复制/粘贴功能的额外积分，但我可以没有它。

注意： 如果不清楚，我不能将 HTML 或 JavaScript 添加到页面 - 只有 CSS。

---

（我唯一发现的是这个问题，但它正在处理与 jQuery 相关的问题并且它有一个 JavaScript 解决方案）

Answer 1

正如@ThiefMaster 建议的那样

input.pw {
    -webkit-text-security: disc;
}

但是，这将适用于 webkit 后代的浏览器。Opera、Chrome 和 Safari，但对其余的支持不多，另一个解决方案是使用 webfonts。

使用任何字体编辑实用程序（如FontForge）来创建包含所有字符*（或您想要的任何符号）的字体。然后使用 CSS 网络字体将它们用作自定义字体。

Answer 2

You can create a font made only of dots

@font-face
    {
    font-family:'dotsfont';
    src:url('dotsfont.eot');
    src:url('dotsfont.eot?#iefix')  format('embedded-opentype'),
        url('dotsfont.svg#font')    format('svg'),
        url('dotsfont.woff')        format('woff'),
        url('dotsfont.ttf')         format('truetype');
    font-weight:normal;
    font-style:normal;
}

input.myclass
    {-webkit-text-security:disc;font-family:dotsfont;}

This might be what you're looking for...

There are many glyphs to define but there might be a simpler way to do that.. You can create a totally empty font and define only the .notdef glyph (glyph ID 0) which is used as a replacement when another glyph is not defined

As you probably know, it usually looks like this:

So, you should replace that with a dot/asterisk and test what happens with browsers... because i'm not sure if it does work on all of them (some may want to use their own missing glyph replacement). Let me know if you try...

Answer 3

在基于 WebKit 的浏览器中，您可以使用该-webkit-text-security属性来执行此操作。它甚至允许您选择子弹的形状（圆盘、圆形、方形）。

input.pw {
    -webkit-text-security: disc;
}

演示

input.pw {
  -webkit-text-security: disc;
}

input.pw2 {
  -webkit-text-security: circle;
}

input.pw3 {
  -webkit-text-security: square;
}

<input type="text" class="pw" value="secret">
<input type="text" class="pw2" value="secret">
<input type="text" class="pw3" value="secret">

然而，这显然是不标准的。至少Safari CSS 文档说它是“Apple 扩展”。它在 Chrome 中运行良好 - 显然 - 但我认为没有任何其他渲染引擎支持它......

Answer 4

您可以使用自定义字体输入带有类型文本的虚假密码。以下适用于chrome，firefox，edge ...

@font-face {
  font-family: 'password';
  font-style: normal;
  font-weight: 400;
  src: url(https://jsbin-user-assets.s3.amazonaws.com/rafaelcastrocouto/password.ttf);
}

input.key {
  font-family: 'password';
  width: 100px; height: 16px;  
}

<p>Password: <input class="key" type="text" autocomplete="off" /></p>

Answer 5

我最近多次出现在这个线程中。我的解决方案是利用JQuery输入事件（虽然它也可以写成原始JS的，或者如果你需要的话，甚至可以写成C#（Blazor），想法是一样的）：

核心部分是：

if (isPasswordVisible) { // if password is visible, then simply update value stored in the dictionary
    value = newValue;
    passwordInputsValues[$passwordInput.attr("my-guid")] = value;
} else { // else compute and update stored value
    const newValueUntilCaret = newValue.take(caretPosition); // take chars before the caret
    const unchangedCharsAtStart = newValueUntilCaret.takeWhile(c => c === "●").length; // count unchanged chars from the beginning
    const unchangedCharsAtEnd = newValue.skip(caretPosition).length; // count unchanged chars after the caret
    const insertedValue = newValueUntilCaret.skip(unchangedCharsAtStart); // get newly added string if any
    value = oldValue.take(unchangedCharsAtStart) + insertedValue + oldValue.takeLast(unchangedCharsAtEnd); // create new value as concatenation of old value left part, new string and old value right part
    passwordInputsValues[$passwordInput.attr("my-guid")] = value; // store newly created value in the dictionary
    $passwordInput.prop("value", value.split("").map(_ => "●").join("")); // set value of the input to new masked value
    $passwordInput[0].setSelectionRange(caretPosition, caretPosition); // set caret position to match the appropriate position 
}

以下是示例密码控制的完整代码（如果出现任何问题，我会尝试更新它）：

// Utils 

var guid = () => {
    return "xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx".replace(/[xy]/g, function (c) {
        const r = Math.random() * 16 | 0;
        const v = c === "x" ? r : r & 0x3 | 0x8;
        return v.toString(16);
    });
}

// Array Extensions

Object.defineProperty(Array.prototype, "skip", {
    value: function (n) {
        if (typeof (n) !== "number") {
            throw new Error("n is not a number");

        }
        return this.slice(0, n);
    },
    writable: true,
    configurable: true

Object.defineProperty(Array.prototype, "takeLast", {
    value: function (n) {
        if (typeof (n) !== "number") {

        }
        return this.slice(Math.max(this.length - n, 0));
    },
    writable: true,
    configurable: true
});

Object.defineProperty(Array.prototype, "takeWhile", {
    value: function (condition) {
        if (typeof (condition) !== "function") {
            throw new Error("condition is not a function");
        }

        const arr = [];
        for (let el of this) {
            if (condition(el))
                arr.push(el);
            else

        }
        return arr;
    },
    writable: true,
    configurable: true
});

Answer 6

我使用了这个项目中的字体https://github.com/noppa/text-security。这是“圆盘”的样式（“圆形”或“方形”也可以这样做）

@font-face {
  font-family: 'text-security-disc';
  src: url('fonts/text-security-disc.woff2') format('woff2'),
    url('fonts/text-security-disc.woff') format('woff');
}

.text-security-disc {
  font-family: text-security-disc;
  /* Use -webkit-text-security if the browser supports it */
  -webkit-text-security: disc;
}

Answer 7

我希望输入类型文本和密码看起来相同，同时仍为密码输入字段提供 ***** 的安全性

CSS

input[type="text"],
select {
  width: 90%;
  padding: 10px 20px;
  margin: 8px 0;
  display: inline-block;
  border: 1px solid #ccc;
  border-radius: 1px;
  box-sizing: border-box;
}
input[type="password"],
select {
  width: 90%;
  padding: 10px 20px;
  margin: 8px 0;
  display: inline-block;
  border: 1px solid #ccc;
  border-radius: 1px;
  box-sizing: border-box;
}

HTML

<input
    type="text"
    name="email"
    placeholder="user@email.com"
/>

<input
    type="password"
    name="password"
    placeholder="*********************"
/>

Answer 8

基本上你可以做

input { -webkit-text-security: disc; }

在你的css文件里面。

但请注意，有人可以简单地在 Chrome 中“检查元素”并将 css 元素从“disc”更改为“none”，这样真实的文本就会一目了然。

至于禁用选择/复制，请参阅这篇文章： 如何使用 CSS 禁用文本选择突出显示？

Answer 9

这仅适用于text字段（：

input { -webkit-text-security: none; } 
input { -webkit-text-security: circle; } 
input { -webkit-text-security: square; } 
input { -webkit-text-security: disc; /* Default */ }

Answer 10

如果您想阻止复制粘贴功能，那么您可以使用：

-webkit-touch-callout: none; -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: moz-none; -ms-user-select: none; user-select: none;

这不会让其他人选择文本，因此他们将无法复制。
