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] ) (修改值)
var settings = { validate: false, limit: 5, name: "foo" };
var options = { validate: true, name: "bar" };
jQuery.extend(settings, options);
jQuery.grep( array, callback, [invert] ) (剔除)
var arr = [ 1, 9, 3, 8, 6, 1, 5, 9, 4, 7, 3, 8, 6, 9, 1 ];
$("div").text(arr.join(", "));

return (n != 5 && i > 4);
});
$("p").text(arr.join(", "));
arr = jQuery.grep(arr, function (a) { return a != 9; });
$("span").text(arr.join(", "));
jQuery.makeArray( obj ) (生成数组)
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 ) (自定义处理数组)
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 + a; });
$("span").text(arr.join(", "));
jQuery.inArray( value, array ) (查找 -1:找不到)
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 ) (去重)
jQuery.unique(divs)
