jquery grep()筛选遍历数组

$().ready(function(){ var array = [1,2,3,4,5,6,7,8,9];var filterarray = $.grep(array,function(value){ return value > 5;//筛选出大于5的});for(var i=0;i<filterarray.length;i++){ alert(filterarray[i]);}for (key in filterarray){ alert(filterarray[key]);}});

jquery each()筛选遍历数组

$().ready( function(){ var anObject = {one:1,two:2,three:3};//对json数组each $.each(anObject,function(name,value) { alert(name); alert(value); }); var anArray = ['one','two','three']; $.each(anArray,function(n,value){ alert(n); alert(value); } ); });

jquery inArray()筛选遍历数组

$().ready( function(){ var anArray = ['one','two','three']; var index = $.inArray(‘two’,anArray); alert(index);//返回该值在数组中的键值，返回1 alert(anArray[index]);//value is two });

jquery map()筛选遍历数组

$().ready(

function(){ var strings = ['0','1','2','3','4','S','6']; var values = $.map(strings,function(value){ var result = new Number(value); return isNaN(result) ? null:result;//isNaN:is Not a Number的缩写 } ); for (key in values) { alert(values[key]); } });

jquery遍历解析json对象1：

var json = [{dd:'SB',AA:'东东',re1:123},{cccc:'dd',lk:'1qw'}];for(var i=0,l=json.length;i<l;i++){ for(var key in json[i]){ alert(key+’:'+json[i][key]); }}

jquery遍历解析json对象2

有如下 json对象：var obj ={”name”:”冯娟”,”password”:”123456″,”department”:”技术部”,”sex”:” 女”,”old”:30};遍历方法：for(var p in obj){ str = str+obj[p]+’,’; return str;}
