1、for循环
var arr = new array(13.5,3,4,5,6);for(var i=0;i<arr.length;i++){ arr[i] = arr[i]/2.0;}
2、for,in循环
var xvar mycars = new array()mycars[0] = "saab"mycars[1] = "volvo"mycars[2] = "bmw"for (x in mycars){ document.write(mycars[x] + "<br />")}
3、each遍历一维数组
var arr=new array();arr=["aaa","bbb","ccc"];$.each(arr,function(index,value){ alert(i+"..."+value);});
4、each遍历二维数组
$(function () { $.each([["aaa", "bbb", "ccc"], ["ddd", "eee", "fff"], ["ggg", "hhh", "iii"]], function (index, item) { alert(index + "..." + item); //输出0...aaa,bbb,ccc 1...ddd,eee,fff 2...ggg,hhh,iii 这时的index为数组下标,item相当于取这二维数组中的每一个数组 $.each(item, function (index, itemobj) { alert(index + "....." + itemobj); }); }); //输出0...aaa,bbb,ccc 0...aaa 1...bbb 2...cccc 1...ddd,eee,fff 0...ddd 1...eee 2...fff 2...ggg,hhh,iii 0...ggg 1...hhh 2...iii });
