Jquery plugin Development notes _ jquery

These two have been watching the development of Jquery plug-ins. I found related articles on the Internet last time, but I did not remember them, so it would be hard to find them again. I had to write an article by myself, so I could remember it later!
First paste the plug-in code, which is annotated

The Code is as follows:

(Function ($ ){
// Extension
$. Fn. extend ({
// Plug-in name
Height: function (options ){
// Default parameter
Var defaults = {
Color: 'red'
};
// Overwrite the default parameters
Var opts = $. extend (defaults, options );
// Main Function
Return this. each (function (){
// Activate the event
Var obj = $ (this );
Obj. click (function (){
Alert (opts. color );
});
});
}
})
}) (JQuery );
// Note that jQuery must follow this method. Q must be capitalized, and j cannot be capitalized. Otherwise, an error occurs.

The following code is used:

The Code is as follows:

@{
ViewBag. Title = "Home Page ";
}
@ Section Header {
