Javascript 使用ajax+;js
我想在symfony 4下实现实时搜索,但我被卡住了。 我希望你能帮助我的朋友 我的控制器Javascript 使用ajax+;js,javascript,ajax,symfony,doctrine-orm,symfony4,Javascript,Ajax,Symfony,Doctrine Orm,Symfony4,我想在symfony 4下实现实时搜索,但我被卡住了。 我希望你能帮助我的朋友 我的控制器 /** * @Route("/search", name="search") */ public function searchAction(Request $request){ $user = new User(); $searchTerm = $request->query->get('search'); $em = $t
/**
* @Route("/search", name="search")
*/
public function searchAction(Request $request){
$user = new User();
$searchTerm = $request->query->get('search');
$em = $this->getDoctrine()->getManager();

//$results = $query->getResult();
$content = $this->renderView('search.html.twig', [
'res' => $results,
'val' => $searchTerm
]);
$response = new JsonResponse();
$response->setData(array('list' => $content));
return $response;
}
我的脚本ajax
这是我的ajax脚本
$.ajax({
type: "GET",
url: "{{ path('search') }}",
dataType: "json",
data: {search: input},
cache: false,
success: function (response) {
$('.example-wrapper').replaceWith(response);
//$('.example-wrapper').load("{{ path('search') }}?search="+ $search.val());
console.log(response);
},
error: function (response) {
console.log(response);
}
});
search.html.twig
搜索
{%res%中的结果为%res}
{{result.fullname}
{{result.username}
{{result.email}
{{result.roles[0]}}
{%endfor%}
搜索页面看起来好像我看不到表单,除非去掉ajax脚本
你很接近了。:)就我个人而言,我会这样做
行动职能:
/**
* Search action.
* @Route("/search/{search}", name="search")
* @param Request $request Request instance
* @param string $search Search term
* @return Response|JsonResponse Response instance
*/
public function searchAction(Request $request, string $search)
{
if (!$request->isXmlHttpRequest()) {
return $this->render("search.html.twig");
}
if (!$searchTerm = trim($request->query->get("search", $search))) {
return new JsonResponse(["error" => "Search term not specified."], Response::HTTP_BAD_REQUEST);
}
$em = $this->getDoctrine()->getManager();
if (!($results = $em->getRepository(User::class)->findOneByEmail($searchTerm))) {
return new JsonResponse(["error" => "No results found."], Response::HTTP_NOT_FOUND);
}
return new JsonResponse([
"html" => $this->renderView("search.ajax.twig", ["results" => $results]),
]);
}
您的search.html.twig
不应包含带有结果的for循环,而应仅包含以下内容,而不是for循环:

<div>
<input type="text" class="form-control" name="search">
<button type="submit" class="btn btn-success" name="sub">search</button>
</div>
</form>
<div id="search-results" class="example-wrapper"></div>
<script type="text/javascript"><!--
jQuery(document).ready(function($){
$('#search-form').submit(function(e){
e.preventDefault();
$('#search-results').html("");
$.get("{{ path('search') }}/" + input, function(data, textStatus, xhr){
if ("object" !== typeof data || null === data) {
alert("Unexpected response from server.");
return;
}
if (!data.hasOwnProperty("html") || typeof data.html != "string" || (data.html = data.html.trim()).length < 1) {
alert("Empty response from server.");
return;
}
$('#search-results').html(data.html);

var error = "Unknown error occurred.";

hey adambean非常感谢您的帮助,但仍然存在问题:(1/4)ResourceNotFoundException(2/4)NotFoundHttpException未找到“获取/搜索”的路由(3/4)错误类“App\Controller\ExceptionController”未找到(4/4)InvalidArgumentException控制器“App\Controller\ExceptionController”既不作为服务也不作为类存在。如果您有任何想法,请告诉我其他人给我发送电子邮件,我想问您。ResourceNotFoundException:这可能是因为“search.html.twig”缺失或“search.ajax.twig”缺失。NotFoundHttpException:更改
公共函数searchAction(Request$Request,string$search)
topublic function searchAction(Request$Request,string$search=null)
No,这与社区讨论的堆栈交换精神背道而驰。请将此公开供公众讨论和贡献。
