JavaScript-<form> button,submit,reset including <form> own Name property is not all that useless?

I was scattered to learn, nor did the project, that is, every learning an object, a function, I do the experiment, there are related things, I put a similar to the bait

I know

The name in is really useful and can be used to pass values to PHP, but

Is there no other use in the name attribute in addition to the Document.getelementsbyname ("") [0] and the $ ("[name=]") of jQuery in JavaScript?
As long as I do not use JS, then I do not have to write the Name property, right?

And there's this.

What's the use of value in? They are not a Boolean value, the choice is true, not selected false? With checked can determine, why there is a value, this how to pass the server?

1. When the button type= "Submit", there is a name, and method= "get", is committed, type= "button | Reset "No matter if name is not

2.type= "Radio" value is passed to the back end, checked can only JS to judge, as long as there is a name, will naturally put the selected value to the backend

You look like a novice!
I'm going to try to give you the answer.
1. Does the button,submit,reset include its own name attribute?
It's no use, no matter what you get by $_get and $_post, you get the value, you get the button value of the foreground, the value of the submit and reset are useless, the so-called value is the text displayed on the button, personally, Name just does some pre-JS and jquery operations.
2.

This is useful, set the radio button's Value property, the two values are different, such as: a set for the male, a set for the female, you back end is to get after the judgment of the OH. You can do some logical processing based on value that is worth doing differently.
I don't know what I'm talking about, read the manual.
