<input type="text" id="name" name="name" placeholder="your name" required><br>

So my question actually is:

所以我的问题实际上是:

In short, the nameis the identifier that is sent to the server when you submit the form. The idis a unique identifier for the browser, clientside, for javascript and such.

简而言之,name就是提交表单时发送到服务器的标识符。的id是用于浏览器中,客户机侧的唯一标识符,用于javascript和这样。

回答by Phrogz

The nameattribute is for submitting a form element to the server; many elements may share the same name(e.g. radio buttons, which musthave the same name within the set).

name属性用于向服务器提交表单元素;许多元素可能共享相同的name(例如,单选按钮,在集合中必须具有相同的名称)。

The idattribute is for uniquely identifying any element (not just form elements). It mustbe unique throughout the entire document.

id属性用于唯一标识任何元素(不仅仅是表单元素)。它在整个文档中必须是唯一的。

回答by Tony R

The idattribute is supposed to be unique in your document. Only one element can have a given id. document.getElementById()finds the first element with the given id.

id属性在您的文档中应该是唯一的。只有一个元素可以有一个给定的 id。document.getElementById()查找具有给定 的第一个元素id

The nameattribute is used by forms as the key in a key/value pair when submitting the form. The valueattribute is both displayed in the browser, and submitted with the form.

name提交表单时,该属性被表单用作键/值对中的键。该value属性既显示在浏览器中,又与表单一起提交。

Neither is "more important," they're just different. If you have an XML mindset, they're both just attributes on a node. In HTML they have more meaning though.

两者都不是“更重要”,它们只是不同。如果您有 XML 思维,那么它们都只是节点上的属性。在 HTML 中,它们有更多的含义。
