我可以隐藏HTML5号码输入的旋转框吗？

本文翻译自：Can I hide the HTML5 number input’s spin box?

Is there a consistent way across browsers to hide the new spin boxes that some browsers (such as Chrome) render for HTML input of type number? 跨浏览器是否有一致的方法来隐藏某些浏览器（如Chrome）为类型编号的HTML输入呈现的新旋转框？ I am looking for a CSS or JavaScript method to prevent the up/down arrows from appearing. 我正在寻找一种CSS或JavaScript方法来防止上/下箭头出现。

<input id="test" type="number">

Try using input type="tel" instead. 请尝试使用input type="tel" 。 It pops up a keyboard with numbers, and it doesn't show spin boxes. 它弹出一个带数字的键盘，它不显示旋转框。 It requires no JavaScript or CSS or plugins or anything else. 它不需要JavaScript或CSS或插件或其他任何东西。

Firefox 29 currently adds support for number elements, so here's a snippet for hiding the spinners in webkit and moz based browsers: Firefox 29目前增加了对数字元素的支持，所以这里有一个片段用于在基于webkit和moz的浏览器中隐藏微调器：

 input[type='number'] { -moz-appearance:textfield; } input::-webkit-outer-spin-button, input::-webkit-inner-spin-button { -webkit-appearance: none; }

 <input id="test" type="number">

To make this work in Safari I found adding !important to the webkit adjustment forces the spin button to be hidden. 为了在Safari中使用，我发现添加！对webkit调整非常重要，强制隐藏旋转按钮。

input::-webkit-outer-spin-button,
input::-webkit-inner-spin-button {
    /* display: none; <- Crashes Chrome on hover */
    -webkit-appearance: none !important;
    margin: 0; /* <-- Apparently some margin are still there even though it's hidden */
}

I am still having trouble working out a solution for Opera as well. 我仍然无法为Opera制定解决方案。

Short answer: 简短回答：

 input[type="number"]::-webkit-outer-spin-button, input[type="number"]::-webkit-inner-spin-button { -webkit-appearance: none; margin: 0; } input[type="number"] { -moz-appearance: textfield; }

 <input type="number" />

To add to existing answer... 要添加到现有答案......

Firefox: 火狐：

In current versions of Firefox, the (user agent) default value of the -moz-appearance property on these elements is number-input . 在当前版本的Firefox中，这些元素上的-moz-appearance属性的（用户代理）默认值是number-input 。 Changing that to the value textfield effectively removes the spinner. 将其更改为值textfield有效地删除微调器。

input[type="number"] {
    -moz-appearance: textfield;
}

In some cases, you may want the spinner to be hidden initially , and then appear on hover/focus. 在某些情况下，您可能希望最初隐藏微调器，然后显示在悬停/焦点上。 (This is currently the default behavior in Chrome). （这是目前Chrome中的默认行为）。 If so, you can use the following: 如果是这样，您可以使用以下内容：

 input[type="number"] { -moz-appearance: textfield; } input[type="number"]:hover, input[type="number"]:focus { -moz-appearance: number-input; }

 <input type="number"/>

Chrome: 铬：

In current versions of Chrome, the (user agent) default value of the -webkit-appearance property on these elements is already textfield . 在当前版本的Chrome中，这些元素上的-webkit-appearance属性的（用户代理）默认值已经是textfield 。 In order to remove the spinner, the -webkit-appearance property's value needs to be changed to none on the ::-webkit-outer-spin-button / ::-webkit-inner-spin-button pseudo classes (it is -webkit-appearance: inner-spin-button by default). 为了删除微调器，需要在::-webkit-outer-spin-button / ::-webkit-inner-spin-button伪类上将-webkit-appearance属性的值更改为none （它是-webkit-appearance: inner-spin-button默认情况下为-webkit-appearance: inner-spin-button ）。

 input[type="number"]::-webkit-outer-spin-button, input[type="number"]::-webkit-inner-spin-button { -webkit-appearance: none; margin: 0; }

 <input type="number" />

It's worth pointing out that margin: 0 is used to remove the margin in older versions of Chrome. 值得指出的是： margin: 0用于删除旧版 Chrome中的保证金。

Currently, as of writing this, here is the default user agent styling on the 'inner-spin-button' pseudo class: 目前，在撰写本文时，这里是'inner-spin-button'伪类的默认用户代理样式：

input::-webkit-inner-spin-button {
    -webkit-appearance: inner-spin-button;
    display: inline-block;
    cursor: default;
    flex: 0 0 auto;
    align-self: stretch;
    -webkit-user-select: none;
    opacity: 0;
    pointer-events: none;
    -webkit-user-modify: read-only;
}

I've encountered this problem with a input[type="datetime-local"] , which is similar to this problem. 我在input[type="datetime-local"]遇到了这个问题，这与此问题类似。

And I've found a way to overcome this kind of problems. 我找到了克服这类问题的方法。

First, you must turn on chrome's shadow-root feature by "DevTools -> Settings -> General -> Elements -> Show user agent shadow DOM" 首先，你必须通过“DevTools - >设置 - >常规 - >元素 - >显示用户代理阴影DOM”打开chrome的阴影根功能

Then you can see all shadowed DOM elements , for example, for <input type="number"> , the full element with shadowed DOM is: 然后你可以看到所有阴影的DOM元素 ，例如，对于<input type="number"> ，带有阴影DOM的完整元素是：

 <input type="number"> <div id="text-field-container" pseudo="-webkit-textfield-decoration-container"> <div id="editing-view-port"> <div id="inner-editor"></div> </div> <div pseudo="-webkit-inner-spin-button" id="spin"></div> </div> </input>
