1. User Agent

JQuery. browser (safari, opera, msie, mozilla)
$. Browser. msie
JQuery. each (jQuery. browser, function (I, val ){
$ ("<Div>" + I + ": <span>" + val + "</span> ")
. AppendTo (document. body );
});

JQuery. browser. version (version)
Internet Explorer: 6.0, 7.0
Mozilla/Firefox/Flock/Camino: 1.7.12, 1.8.1.3 and 1.9
Opera: 1, 9.20
Safari/Webkit: 312.8, 418.9

JQuery. boxModel (whether to use W3C Model)


2. Array and Object operations

JQuery. each (object, callback)
Var arr = ["one", "two", "three", "four", "five"];
Var obj = {one: 1, two: 2, three: 3, four: 4, five: 5 };

JQuery. each (arr, function (){
$ ("#" + This). text ("My id is" + this + ".");
Return (this! = "Four"); // will stop running to skip "five"
});

JQuery. each (obj, function (I, val ){
$ ("#" + I). append (document. createTextNode ("-" + val ));
});

JQuery. extend (target, object1, [objectN]) (modify value)
Var settings = {validate: false, limit: 5, name: "foo "};
Var options = {validate: true, name: "bar "};
JQuery. extend (settings, options );

JQuery. grep (array, callback, [invert]) (excluded)
Var arr = [1, 9, 3, 8, 6, 1, 5, 9, 4, 7, 3, 8, 6, 9, 1];
$ ("Div"). text (arr. join (","));

Arr = jQuery. grep (arr, function (n, I ){
Return (n! = 5 & I> 4 );
});
$ ("P"). text (arr. join (","));

Arr = jQuery. grep (arr, function (a) {return! = 9 ;});
$ ("Span"). text (arr. join (","));

JQuery. makeArray (obj) (generate an array)
Var arr = jQuery. makeArray (document. getElementsByTagName ("div "));
Arr. reverse (); // use an Array method on list of dom elements
$ (Arr). appendTo (document. body );

JQuery. map (array, callback) (custom processing array)
Var arr = ["a", "B", "c", "d", "e"]
$ ("Div"). text (arr. join (","));

Arr = jQuery. map (arr, function (n, I ){
Return (n. toUpperCase () + I );
});
$ ("P"). text (arr. join (","));

Arr = jQuery. map (arr, function (a) {return a + ;});
$ ("Span"). text (arr. join (","));

JQuery. inArray (value, array) (-1: Not found)
Var arr = [4, "Pete", 8, "John"];

$ ("Span: eq (0)"). text (jQuery. inArray ("John", arr ));
$ ("Span: eq (1)"). text (jQuery. inArray (4, arr ));
$ ("Span: eq (2)"). text (jQuery. inArray ("David", arr ));

JQuery. unique (array) (deduplication)

JQuery. unique (divs)


3. Test operations

JQuery. isFunction (obj) (whether it is a function)
Function stub (){
}
Var objs = [
Function (){},
{X: 15, y: 20 },
Null,
Stub,
"Function"
];

JQuery. each (objs, function (I ){
Var isFunc = jQuery. isFunction (objs [I]);
$ ("Span: eq (" + I + ")"). text (isFunc );
});


4. String operations

JQuery. trim (str) (remove spaces)
