通過js生成一個form，用這個form提交參數，並返回“流”類型的數據。在實現過程中，頁面也沒有進行刷新。
var form = $("<form>"); //定義一個form表單
form.attr('style','display:none'); //在form表單中添加查詢參數
form.attr('target','');
form.attr('method','post');
form.attr('action',"exportSms");
var input1 = $('<input>');
input1.attr('type','hidden');
input1.attr('name','exportPostTime');
input1.attr('value',timeString);
$('body').append(form); //將表單放置在web中
form.append(input1); //將查詢參數控件提交到表單上
form.submit(); //表單提交
