我的菜单中有两个public function acceptedChallenges($user_one_id, $user_two_id) {
$stmt = $this->conn->prepare("SELECT u.name, c.user_one_id, c.user_two_id, c.status, c.created_at, c.isRead, c.id FROM users u, challenges c
WHERE c.user_one_id = ? AND
c.user_two_id = ? AND c.status = 1 AND (u.id = c.user_one_id OR u.id = c.user_two_id)");
$stmt->bind_param("ii", $user_one_id, $user_two_id);
if ($stmt->execute()) {
$request = $stmt->get_result();
$stmt->close();
return $request;
} else {
return NULL;
}
}
元素。我想要实现的是在单击它们时在类之间切换。如果我点击第一个，它应该得到$app->post('/accepted_challenges', 'authenticate', function() use ($app) {
verifyRequiredParams(array('user_one_id', 'user_two_id'));
$response = array();
$db = new DbHandler();
$user_one_id = $app->request->post('user_one_id');
$user_two_id = $app->request->post('user_two_id');
$requests = $db->acceptedChallenges($user_one_id, $user_two_id);
if ($requests != NULL) {
$response["error"] = false;
$response["requests"] = array();
while ($request = $requests->fetch_assoc()) {
$tmp = array();
$tmp["name"] = $request["name"];
$tmp["id"] = $request["id"];
$tmp["user_one_id"] = $request["user_one_id"];
$tmp["user_two_id"] = $request["user_two_id"];
$tmp["created_at"] = $request["created_at"];
$tmp["isRead"] = $request["isRead"];
array_push($response["requests"], $tmp);
}
} else {
$response["error"] = true;
$response["message"] = "No pending requests.";
}
echoRespnse(200, $response);
});
类，另一个得到<li>类。
到目前为止我的代码无法正常工作，我找不到办法。
.activeBtn答案 0 :(得分：1)
解决了我不知道removeClass。
$(".menuBtns").click(function() {
// remove classes from all
$(".menuBtns").removeClass("activeBtn");
// add class to the one we clicked
$(this).addClass("activeBtn"); });
