我创建了一个网站，其中有一个包含超过13,000条记录的表格，我正在尝试将每个字母用户输入网站刷新的过滤器用这个字母过滤记录，但该字段会失去对提交的关注。
我该如何解决这个问题？
我尝试使用Cookie跟随sephiith问题的示例，但它仍然失败。 我如何提交示例：
$(function() {
$('input').keyup(function() {
this.value = this.value.toLocaleUpperCase();
this.form.submit();
});
});
页面代码
<?php
session_start();
if (!isset($_SESSION['LOGIN'])) {
header("location: index.php");
}
include("config.php");
require("rep.php");
if (isset($_SESSION['active']) && (time() - $_SESSION['active'] > 1800)) {
session_unset();
session_destroy();
}
$_SESSION['active'] = time();

尝试用ajax来完成它所以页面根本不会刷新，在信件印刷机上刷新整个页面似乎不切实际：
HTML：
<input type="text" id="field"/>
<div id="showContent"></div>
jQuery的：
function findWithLetter(){
$("#field").on("keyup",function(e){
var Val = $(this).val();
$.post("url\to\php",{Val:Val},function(answer){
$("#showContent").html(answer);
});
});
}
PHP：
$val = $_POST['Val'];
$ans = "";
$query = $mysqli->query("SELECT * FROM `table` WHERE name LIKE '$val%'");
while($row = $query->fetch_object()){
$ans.="<div>$row->name</div>";
}
echo $ans;

正如你所说，网站刷新所以我认为将该领域重点放在dom上。
$(function() {
if($('input').val().length > 0){
$('input').focus();
}
});
