tag안에 name, id 차이...펌

The name is used when sending data in a form submission. Different controls respond differently. For example, you may have several radio buttons with different ids, but the same name. When submitted, there is just the one value in the response - the radio button you selected. Of course, there's more to it than that, but it will definitely get you thinking in the right direction. share|improve this answer answered Sep 9 '09 at 4:58 John Fisher 12.6k21838

No problem. We won't show you that ad again. Why didn't you like it?

Oops! I didn't mean to do this.

Use name attributes for form controls (such as <input> and <select>), as that's the identifier used in the POST or GET call that happens on form submission. Use id attributes whenever you need to address a particular HTML element with CSS, JavaScript or a fragment identifier. It's possible to look up elements by name, too, but it's more efficient to look them up by ID.
