we can use the following code to replace this type of notation:

var direction = x
(2) uses JSON as the data format
great Douglas Crockford invented the JSON data format to store data, you can use native JavaScript methods to store complex data without any additional transformations, such as:
the effects should be in the multi-rail playback when the whole, because the individual play the sound of an instrument is different. EQ do not add too much, so as to make the sound more natural, did not lose the original charm.
9, do not put too many instruments in a band, especially if. Sound source is better. Then use EQ to adjust the distribution of the whole instrument in the spectrum, and strive to give each instrument a certain spectrum space. such as the acoustic
certain guitars in an online auction site." This request reaches a server running a PHP program over the network. The PHP server has to return a lot of information to JavaScript, and that information must be sent to the client in some form of data packet that can be parsed by JavaScript. So the data can be packaged in a number of groups and then converted to JSON, like this:
$itemGuitar = Array (
"id" => "itemguitar",
"description" => "Pete Townshend once played this
example:
The Code is as follows:
Var band = {"Name": "The Red Hot Chili Peppers ","Members ":[{"Name": "Anthony Kiedis ","Role": "lead vocals"},{"Name": "Michael 'flea' Balzary ","Role": "bass guitar, trumpet, backing vocals"},{"Name": "Chad Smith ","Role": "drums, percussion"},{"Name": "John Frusciante ","Role": "Lead Guitar"}],"Year": "2009"}
You can use JSON directly in JavaScript, or even as a form
. For example:
01 varBand = {02"Name":"The Red Hot Chili Peppers",03"Members":[04{05"Name":"Anthony Kiedis",06"Role":"Lead vocals"07},08{09"Name":"Michael Flea Balzary",10"Role":"Bass guitar, trumpet, backing vocals"11},12{13"Name":"Chad Smith",14"Role":"Drums, percussion"15},16{17"Name":"John Frusciante",18"Role":"Lead Guitar"19}20],21"Year":"2009"22}

You can directly use JSON in JavaScript, or even return data objects as some APIs. The following code calls an API of delicious.com, the famous bookmarkdon.com,

Knowledge Description:Beginner JavaScript, pay attention to the following seven big details, in the case of the same function, make our code more understandable, more efficient.First, Simplifying CodeExample: Creating an ObjectThis is the way it was before:Var car = new Object ();Car.color = "Red";Car.wheels = 4;Car.age = 8;And now it can be written like this:Var car = {color: ' Red ', Wheels:4, Age:8}Example: Creating an arrayThis is the way it was before:Var Studentarray = new Array (' Zhangsa
the need for additional conversions that can be accessed directly. JSON is the abbreviation for "JavaScript Object Notation", which uses the two shorthand methods mentioned above. So, if you want to describe a band, you might write like this:var band = {"Name": "The Red hot Chili Peppers", "members": ["{" "Name": "Anthony Kiedis", "role": "Leads vocals" 0 7},08 {"Name": "Michael ' Flea ' Balzary", "role": "Bass guitar, trumpet, backing vocals" one},1

You can directly use JSON in JavaScript, encapsulate it in a function, or even use it as the return value form of an API. We call this JSON-P, and many APIs use this form.You can call a dat

You can directly use JSON in JavaScript, encapsulate it in a function, or even use it as the return value form o
", "lastName": "Clapton", "instrument": "guitar "},{"FirstName": "Sergei", "lastName": "Rachmaninoff", "instrument": "piano "}]}
It is worth noting that each value can contain multiple values. However, you should also note that the actual name/value pairs in the record can be different between different primary entries (programmers, authors, and musicians. JSON is completely dynamic and allows you to change the data representation mode in the middle o
moviesThatNeedBetterWriters = [ 'Transformers','Transformers2','Avatar','Indiana Jones 4'];
For arrays, there is also a special thing like associating arrays. You will find that many codes define objects as follows:
var car = new Array();car['colour'] = 'red';car['wheels'] = 4;car['hubcaps'] = 'spinning';car['age'] = 4;
This is crazy. Don't be confused. "Join array" is just an alias of an object.
Another way to simplify the code is to use the ternary operator. For example:
var direction;if(x
