在IE环境下处理Ajax提交乱码的步骤

function loadCity(parentid) {
var city = '${hotel.city}';

 $.ajax({
  url: './listCity.jspx?prov='+ encodeURIComponent(parentid),
  type: 'GET',
  dataType: 'JSON',
  timeout: 5000,
  error: function() { alert('加载城市列表失败!'); },
  success: function(msg) {
$("#city").empty();
$.each(eval(msg), function(i, item) {
if(item.city ==city){
$("<option value='" + item.city + "' selected = 'selected'>" + item.city + "</option>").appendTo($("#city"));
}else{
 $("<option value='" + item.city + "'>" + item.city + "</option>").appendTo($("#city"));
}

 
});
  }
 });
}
