問題描述
id 和 name 屬性有什么區別?它們似乎都具有提供標識符的相同目的.
What is the difference between the id and name attributes? They both seem to serve the same purpose of providing an identifier.
我想知道(特別是關于 HTML 表單)是否有必要或出于任何原因鼓勵使用兩者.
I would like to know (specifically with regards to HTML forms) whether or not using both is necessary or encouraged for any reasons.
推薦答案
name 屬性在表單提交中發送數據時使用.不同的控件響應不同.例如，您可能有幾個具有不同 id 屬性但 name 相同的單選按鈕.提交后，響應中只有一個值 - 您選擇的單選按鈕.
The name attribute is used when sending data in a form submission. Different controls respond differently. For example, you may have several radio buttons with different id attributes, but the same name. When submitted, there is just the one value in the response - the radio button you selected.
當然，它的意義遠不止這些，但它肯定會讓你朝著正確的方向思考.
Of course, there's more to it than that, but it will definitely get you thinking in the right direction.
