Question

我会再次问一些类似的问题我的问题开始关闭的风险（我无法删除旧的线程，因为它可能会让我被禁止，它说）..所以我需要解码一个我从HTML传递的ajax字符串表单到ajax和PHP.When我写英文并检查传递的值是否可以：

但是当我用西里尔语写一些时，这个“东西”被发送到php（单词是“ку”，与英语中的“ku”相同）

我试图从24小时内解决这个问题，并阅读了很多我不知所措并完全被阻止的信息。所以再一次有我的代码：

jQuery(document).ready(function ($) {
	new InputStreamReader(conn.getInputStream(), "UTF-8")); 
	$("#food_search").keyup(function(event){
		var search_term =$(this).val();
$.ajax({
	type:"POST",
	url:"http://test.com/bg/%D1%82%D1%8A%D1%80%D1%81%D0%B5%D0%BD%D0%B5-%D0%BD%D0%B0-%D1%85%D1%80%D0%B0%D0%BD%D0%B8/",
	data:{'fsearch':search_term},
	success:function(res){
		$("#food_search_result").html(res);
		console.log(res);
	},
	error: function (xhr, ajaxOptions, thrownError) {
           alert(xhr.status);
           alert(xhr.responseText);
           alert(thrownError);
       }
});
	});
});

<?php
$hostname = "localhost";
$username = "gosho";
$password = "0!ijgls9df";
$databaseName = "dbName";
$connect = new mysqli($hostname, $username, $password, $databaseName);
$fsearch="";

if(!empty($_POST['fsearch'])) {
$fsearch = $_POST['fsearch'];

$req = $connect->prepare("SELECT title FROM food_data_bg WHERE title LIKE ?");
$value = '%'.$fsearch.'%';
$req->bind_param('s', $value);
$req->execute();
$req->store_result();
$num_of_rows = $req->num_rows;
$req->bind_result($title);
if ($req->num_rows == 0){

echo 'Няма резултати';
}
else{
while($data=$req->fetch()){
   ?>
       <div class="search-result">
           <span class="result-title"><?php echo $title; ?></span>
       </div>
       <?php
       }
var_dump($_POST['fsearch']);
$req->free_result();
    }
}
?>

简而言之，这是搜索引擎，如果数据库中存在与输入文本匹配则必须检查每个键，如果存在则显示它。我的问题是：

如何解码发送给php的ajax信息，像往常一样显示西里尔字符而不是％D0％BA等等。

Answer 1

如果你的wand首先向服务器发送一些数据，你需要serialize你的数据。

var request;

$("#foo").submit(function(event) {

  // Prevent default posting of form - put here to work in case of errors
  event.preventDefault();

  // Abort any pending request
  if (request) {
    request.abort();
  }
  // setup some local variables
  var $form = $(this);

  // Let's select and cache all the fields
  var $inputs = $form.find("input");

  // Serialize the data in the form
  var serializedData = $form.serialize();

  // Let's disable the inputs for the duration of the Ajax request.
  // Note: we disable elements AFTER the form data has been serialized.
  // Disabled form elements will not be serialized.
  $inputs.prop("disabled", true);

  // Fire off the request to /form.php
  request = $.ajax({
    url: "/form.php",
    type: "post",
    data: serializedData
  });

  // Callback handler that will be called on success
  request.done(function(response, textStatus, jqXHR) {
    // Log a message to the console
    console.log("Hooray, it worked!");
  });

  // Callback handler that will be called on failure
  request.fail(function(jqXHR, textStatus, errorThrown) {
    // Log the error to the console
    console.error(
      "The following error occurred: " +
      textStatus, errorThrown
    );
  });

  // Callback handler that will be called regardless
  // if the request failed or succeeded
  request.always(function() {
    // Reenable the inputs
    $inputs.prop("disabled", false);
  });

});

<form method="post" accept-charset="UTF-8" id="foo">
  <p>Търсене на храни: <input type="text" name="fsearch" id="food_search"></p>
</form>
<div id="food_search_result"></div>

PHP（即form.php）：

$fsearch = isset($_POST['fsearch']) ? $_POST['fsearch'] : null;

然后尝试将此代码添加到html。 documentation about this

<head>
  <meta charset="UTF-8">
</head>

猜猜问题对我来说并不完全清楚，但我在问到问题的第二天就解决了问题。安德鲁的回答对于sumbit按钮来说真的很棒，但是现在我不会做任何按钮SOOO我修复了在$ connect和代码之后添加一行右边的问题：

$connect->set_charset("utf8");

问题不在于任何deconing，编码至少现在我看到当我输入类似“”或/ php返回\“\”或soo认为将来我将需要你的建议解码，编码所以感谢你们！＆lt; 3我再一次用你的帮助解决了这个问题
