html输入范围步骤作为值的数组 [英] html input range step as an array of values

问题描述

我第一次玩弄了 input type = range ，理想情况下我想将步骤值设置为一个值数组。我查看了规范，我发现了datalist的可能性，但它接收的数据列表仅用于范围内的高亮值，可以这么说，但不能将值设置在范围内。

I've been playing around with the input type=range for the first time, and ideally I'd like to set the step value to an array of values. I looked over the spec and I see the possibility for a datalist but it seams the data list is only used for highlight values in a range, so to speak, but not setting the values in the range.

所以，像这样的东西（理想情况下没有jQuery插件等）：

So, something like this (ideally without a jQuery plugin, etc.):

<input type="range" min="1" max="100" value="0" step="1,3,5,10,20">

推荐答案

根据 W3C规范，step的值可以是any或正浮动点数。就是这样。

According to the W3C spec, the values for step can be "any" or a positive floating-point number. That's it.

step属性（如果指定）必须具有一个值为
的有效浮点数解析为
大于零的数字，或者必须具有与字符串any匹配的ASCII不区分大小写的
的值。

The step attribute, if specified, must either have a value that is a valid floating-point number that parses to a number that is greater than zero, or must have a value that is an ASCII case-insensitive match for the string "any".
