Question

您好我有这个使用js的表单，单击批准按钮后它会将按钮更改为成功并发送数据，它将运行php脚本来更新数据库。该部分正在运行但是我想在发送信息后重新加载页面，但我尝试过的所有内容都无法正常工作。这是我现在拥有的。

JS

$("#approvePirep").on("click", function() {
var a = $(this).data("ppm"), n = $(this).data("pid"), s = $(this).data("pirep-id"), e = $(this);
    $.ajax("includes/ajax/noc/acceptpirep.php?pid=" + n + "&ppm=" + a + "&pirepid=" + s).done(function(a) {
        "1" == a ? e.removeClass("btn-primary").addClass("btn-success") : e.removeClass("btn-primary").addClass("btn-danger");
    }).fail(function() {
        e.removeClass("btn-primary").addClass("btn-danger");
    });
 window.location.href = "https://virtualua.org/ams/index.php?page=noc";
})

发送信息的php

<?php
require("checkstaff.php");
require("../../logaction.php");

function distance($lat1, $lon1, $lat2, $lon2, $unit = "N") {
    $theta = $lon1 - $lon2;
    $dist = sin(deg2rad((float)$lat1)) * sin(deg2rad((float)$lat2)) + cos(deg2rad((float)$lat1)) * cos(deg2rad((float)$lat2)) * cos(deg2rad((float)$theta));
    $dist = acos($dist);
    $dist = rad2deg($dist);
    $miles = $dist * 60 * 1.1515;

    return ($miles * 0.8684);
}

function getAirportValue($icao, $col) {
  global $pdo;

  $query = $pdo->prepare("SELECT $col FROM airports WHERE icao = ?");
  $query->execute([$icao]);
  return $query->fetchColumn();
}

function ppm($point_value) {
  if ($point_value < "25000") {
    $ppm = 1;
  }

    $ppm = 3;
  }

    $ppm = 8;
  }
  if ($point_value >= "150000") {
    $ppm = 10;
  }
  return $ppm;
}

function calcPoints($dep, $arr) {

  $dep_lat = getAirportValue($dep, "latitude");
  $dep_lon = getAirportValue($dep, "longitude");
  $arr_lat = getAirportValue($arr, "latitude");
  $arr_lon = getAirportValue($arr, "longitude");

  $pointpermile = ppm($_GET['ppm']);

  $distance = distance($dep_lat, $dep_lon, $arr_lat, $arr_lon, "n");

  return round($distance * $pointpermile);
}

if(isStaff() == true) {
  if(isset($_GET['pid']) && $_GET['pirepid']) {
    $pinfo = $pdo->prepare("SELECT * FROM pireps WHERE id = ?");
    $pinfo->execute([$_GET['pirepid']]);
    $pinfo = $pinfo->fetch(PDO::FETCH_ASSOC);

    $query = $pdo->prepare("UPDATE pireps SET status = 1 WHERE id = ?")->execute([$_GET['pirepid']]);
    $query1 = $pdo->prepare("UPDATE pilots SET hours = hours + ?, points = points + ?, last_airport = ?, flights = flights + 1, lastpirep = UNIX_TIMESTAMP()  WHERE id = ?")->execute([$pinfo['time'], calcPoints($pinfo['dep'], $pinfo['arr']), $pinfo['arr'], $_GET['pid']]);

    logAction($_GET['pid'], "Accepted PIREP #".$_GET['pirepid']);

    echo 1;
  } else {
    echo 0;
  }
} else {
  echo 0;
}

?>

Answer 1

从JS中删除此行：

window.location.href = "https://virtualua.org/ams/index.php?page=noc";

并将其重新定位到.done() ajax调用中。

收到ajax的回复后，您应该重新定位页面。

$.ajax("includes/ajax/noc/acceptpirep.php?pid=" + n + "&ppm=" + a + "&pirepid=" + s).done(function(a) {
        "1" == a ? e.removeClass("btn-primary").addClass("btn-success") : e.removeClass("btn-primary").addClass("btn-danger");

        window.location.href = "https://virtualua.org/ams/index.php? page=noc";   //here
    }).fail(function() {
        e.removeClass("btn-primary").addClass("btn-danger");
    });

Answer 2

这可能会发生，因为您的代码是异步执行的＆amp;你不知道。只需将重载代码移到成功/错误（如您所需）回调中，如此 -

$("#approvePirep").on("click", function() {
var a = $(this).data("ppm"), n = $(this).data("pid"), s = $(this).data("pirep-id"), e = $(this);
    $.ajax("includes/ajax/noc/acceptpirep.php?pid=" + n + "&ppm=" + a + "&pirepid=" + s).done(function(a) {
        "1" == a ? e.removeClass("btn-primary").addClass("btn-success") : e.removeClass("btn-primary").addClass("btn-danger");
        // here
        window.location.href = "https://virtualua.org/ams/index.php?page=noc";
    }).fail(function() {
        e.removeClass("btn-primary").addClass("btn-danger");
    });
})

Answer 3

我将window.location.href更改为location.href并正确刷新页面，我确实尝试了location.reload，因为它确实有效，但它正在重新加载页面，下次打开一个新模式接受另一个pirep它会从最后一个表单中引入一些但不是全部数据，但是通过使用上面的解决方案来修复。
