循环赋值给数组

vararrRow=newArray();
for(vari=0;i<checkedArr.length;i++){
arrRow[i]=checkedArr[i].FUN_ID;
}

ajax传json数组到后端

$.ajax({
	url:"role.do?method=funcRoleAdd",type:"post",async:false,cache:false,data:{'roleId':selectRow[0].roleId,'checkArr':JSON.stringify(arrRow)},dataType:"json",contentType:"application/x-www-form-urlencoded;charset=UTF-8",success:function(json){
	},error:function(e){
	}
});
