以下 HTML5 代码有效。它允许用户使用 HTML5 type="number" 输入类型捕获小数。这是通过 step 属性实现的： 以下 HTML5 代码有效。它允许用户使用 HTML5 type="number" 输入类型捕获小数。这是通过 step 属性实现的： <input value="" name="turnover" id="turnover" placeholder="0" type="number" step="0.01"> 问题是在南非，我们使用句点（.）作为小数，而不是逗号（,）。不幸的是，Chrome 不允许使用句点并强制用户使用逗号。显然，其他一些浏览器使用您在步骤属性中使用的任何小数点分隔符。似乎不是 Chrome。 有什么想法可以解决这个问题吗？ 您必须将该输入元素的 lang 属性指定为其中句点表示小数而不是逗号的国家/地区的属性，例如。英语 (en) <input type="number" step="0.01" min="0" lang="en"> 您是否尝试过设置页面的文化代码？假设您的网站主要服务南非游客...？ 这是我能想到的最接近的解决方案，可以达到相同的效果。它通过模式属性使用带有正则表达式的文本属性，而不是 HTML5 数字属性。 对于货币（或小数点后两位）： <input type="text" value="0" name="turnover" placeholder="0" pattern="\d+(\.\d{2})?"/> 对于科学（或小数点后 6 位） <input type="text" value="0" name="turnover" placeholder="0" pattern="\d+(\.\d{6})?"/> 对于任何小数位 <input type="text" value="0" name="turnover" placeholder="0" pattern="\d+(\.\d+)?"/> 希望这有帮助。如果您有更好的解决方案，请留言！ 就我而言，我使用网络工具从图中提取数据点（一个名为 WebPlotDigitizer 的网站）。当我提取数据点时，它们以逗号作为小数点分隔符显示。解决方案是将 Chrome 的首选语言从“西班牙语”更改为英语，因此它认为默认的小数分隔符是点
