If you use the for attribute in a label element it has to match the id of an input element in your form.
如果在 label 元素中使用 for 属性，它必须与表单中输入元素的 id 匹配。
ie
IE
<label for="field-id" style="line-height:24px;">Your Name</label><br>
<input type="text" id="field-id">

By definition, the forattributevalue must match the idattribute value of “another” form control, to use the HTML 4.01 terminology. Controlsare created by input, textarea, button, select, or objectelements, so just read “another” as “a”. HTML5 puts this somewhat differently, specifying that the attribute must refer to a labelable element.
根据定义，for属性值必须与id“另一个”表单控件的属性值匹配，使用 HTML 4.01 术语。控件由input、textarea、button、select或object元素创建，因此只需将“another”读作“a”。HTML5 对此有些不同，指定该属性必须引用一个可标记元素。
From the error message, it seems that you are validating against HTML5, so the rule that applies is that the forattribute must refer to a button, input(other than with type=hidden), keygen, meter, output, progress, select, or textareaelement. My guess is that you just forgot the idattribute, incorrectly assuming that the nameattribute could do its job.
从错误消息来看，您似乎正在针对 HTML5 进行验证，因此适用的规则是该for属性必须引用button, input（与type=hidden除外）keygen、meter、output、progress、select、 或textarea元素。我的猜测是您只是忘记了该id属性，错误地假设该name属性可以完成其工作。
