jquery怎么遍历数组

var arr = new Array(13.5,3,4,5,6); for(var i=0;i
        

         Salin selepas log masuk
        
       

var x var mycars = new Array() mycars[0] = "Saab" mycars[1] = "Volvo" mycars[2] = "BMW" for (x in mycars) { document.write(mycars[x] + "
") }

var arr=new Array(); arr=["aaa","bbb","ccc"]; $.each(arr,function(index,value){ alert(i+"..."+value); });

$(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 });
