js遍歷json的key和value

遍歷json對象:
無規律:
<script> var json = [{dd:‘SB‘,AA:‘東東‘,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]); } } </script>
有規律:
packJson = [ {"name":"nikita", "password":"1111"}, {"name":"tony", "password":"2222"} ]; for(var p in packJson){//遍歷json數組時,這麽寫p為索引,0,1 alert(packJson[p].name + " " + packJson[p].password); }
也可以用這個:
for(var i = 0; i < packJson.length; i++){ alert(packJson[i].name + " " + packJson[i].password); }
遍歷json對象
myJson = {"name":"caibaojian", "password":"1111"}; for(var p in myJson){//遍歷json對象的每個key/value對,p為key alert(p + " " + myJson[p]); }
有如下 json對象: var obj ={"name":"馮娟","password":"123456","department":"技術部","sex":"女","old":30}; 遍歷方法: for(var p in obj){ str = str+obj[p]+’,‘; return str; }
