ajax提交url与ajax提交表单的详细比较

1：ajax自已构造一个url,这种方式传参数要用Data,不能用于表单提交。
例:

function fn_check_form(){
    if($("#Name").val() == ""){
alert("人不能为空");
$("#Name").focus();
return false;
}
       }

  function showResponse(responseText) { 
               try{ 
                //alert(responseText);
                   if(responseText == 'true'){ 
                        alert('操作成功！');
                        window.location.reload();
                   }
                   else if(responseText == 'paramFalse')
                   {
                    alert("必填参数不能为空!")
                   }
                   else if(responseText == 'timeError')
                   {
                     alert("出发时间不能大于报销时间!");
                   }
                   else{ 
                        alert('操作失败！'); 
                     //   window.location.relo
