$ funciton can't work

[[email protected]…]

May be my english is not good enough what problem is.My code is in below: var check_arr={

"server": {type:0,reg:"",fn_Y:""}, "port": {type:1,reg:"",fn_Y:""}, "db_user": {type:1,reg:"",fn_Y:""}, "db_password": {type:1,reg:"",fn_Y:""}, "db_name": {type:1,reg:"",fn_Y:""}, "db_prefix": {type:1,reg:"",fn_Y:""}, "admin_user": {type:1,reg:"",fn_Y:""}, "admin_pw": {type:1,reg:"",fn_Y:""}, "admin_re_pw": {type:1,reg:"",fn_Y:""}, "sys_prefix": {type:1,reg:"",fn_Y:""}

}; var bind_fn=function(){

var a=[]; for(var key in check_arr){

a.push($(key).val()); key is id of input,this can't work,but$(document.getElementById(key).val() can work well

}

alert(a.join());

}; I think this should be a bug,I don't want to used $(document.getElementById(key).val() in the future.
