This manual aims to provide clear instructions for use and adaptation in Javascript. If you are very new in web programming, a tutorial is not recommended. The required level is half a rookie, thanks for your understanding!.
Basic Types var intValue
= 1;
var floatValue = 3.0;
var stringValue = "This is a string \\ n";
sqString var = 'This is also a string';
Javascript is a dynamically written language. The variables are declared with the keyword var. Simple common are the types of support. Arrays
emptyList var = [];
homogenousList var = [1, 2, 3];
heterogenousList var = ["one", 2, 3.0];
Javascript has built in collectibles. The matrix is \u200b\u200ban object dynamically sequence of values \u200b\u200bwritten Javascript. They are created with the support of [] notation or the new operator in the object array (Eg, new Array (5)).
Property Maps
emptyMap var = ();
homogenousMap var = ('one': 1, "two": 2, "three": 3);
heterogenousMap var = ('one': 1 ,
"two" "two",
"three": 3.0);
Along with arrays of objects are objects. Act as property maps of the chains that act as keys dynamically typed data. Access
/ / notation property access points
window.alert ("homogeneous map property \\" one \\ ""
homogenousMap.one)
/ / Subscript notation property access window.alert
("homogeneous map property \\" two \\ ""
homogenousMap ["two"]);
Assignment
homogenousMap [ "one"] = 10;
homogenousMap.two = 20;
Elimination
delete homogenousMap ["a"];
delete homogenousMap.two;
Iteration for (var key heterogenousMap) (
window.alert ("heterogeneous map property \\" "key
"\\" = "
heterogenousMap [key]);
)
