Question

<input type ="button" name="buttonsel" id="buttonse1"/>

$("#buttonse1") VS $("[name=buttonse1]")

What are the advantages in using name and id in jquery

Answer 1

EDIT

• The names in name= must be unique within a form. The names in id= must be unique within the entire document.
• JavaScript needed unique names, but there were too many documents already out here without unique name= names, so the W3 people invented the id tag that was required to be unique. Unfortunately older browsers did not understand it. So you need both naming schemes in your forms.

Id can able to indentify element unique.

valid html contains unique id for each element.

<input type ="button" name="buttonsel" id="buttonse1"/>
<input type ="button" name="buttonsel" id="newbutton"/>//valid for both id and name
<input type ="button" name="buttonsel" id="buttonse1"/>//not valid as id repeated but name is valid even if repeated

But you can give same name to multiple items that might not able find element unequally.
