經(jīng)過(guò)多次嘗試后，我需要幫助。單擊事件后，我檢查數(shù)據(jù)庫(kù)中存在的數(shù)據(jù)并使用 jscript 彈出確認(rèn)框。當(dāng)我點(diǎn)擊“取消”時(shí)，如何讓它工作，它沒(méi)有顯示我在confirm.php上設(shè)置的任何值？單擊“確定”確認(rèn)并單擊“取消”j腳本代碼：if($row_count2 > 0){ if ($row2["Status"] == "REJECTED") { <script type="text/javascript"> if (!confirm('Lot No has been REJECTED before.. Double confirm to add the Lot No!!')) { var option = "NO"; $.ajax({ type: "POST", url: "confirm.php", data: "value="+option, success: function (data) { alert(data); } }); } </script> }}$ll = $_SESSION['Confirm'];echo "<script type='text/javascript'>alert('$ll');</script>";if ($row_count2 < 1 || ($_SESSION['Confirm'] = "YES")){ //my insert query is here...}這是在confirm.php里面：<?php session_start(); $xx = $_REQUEST["value"]; $_SESSION['Confirm'] = $xx; echo "<script type='text/javascript'>alert('$xx');</script>";?>我期望獲得$_SESSION['Confirm']“否”的價(jià)值默認(rèn)$_SESSION['Confirm']值為 YESalert(data)$_SESSION['Confirm']顯示 $xx 為“否”，但當(dāng)我在插入查詢值之前在 if 條件上設(shè)置值警報(bào)時(shí)，值$_SESSION['Confirm']仍然保持為“是”

而不是使用 JScript 警報(bào)，這真的很麻煩。我最終使用了模式彈出警報(bào)。
<div class="modal-content">
<div class="modal-header bg-secondary">
<button type="button" class="close" data-dismiss="modal"></button>
<h4 class="modal-title text-white ">Confirmation</h4>
</div>
<div class="modal-body">
<div class="box-body">
<form class="form-signin">
<label for="txtLotNo" class="mr-sm-2 ml-sm-4">Lot No : '.$lotNo.' has been REJECTED before.. Double confirm to add the Lot No!!</label>
<br>
<div class="text-center">
<button type="button" id="getAdd" class="btn btn-warning btn-sm" data-toggle="modal" data-target="#myAdd" data-id="YES'.$lotNo.$newLotNo.'" >YES</button>
<button type="button" id="getAdd" class="btn btn-warning btn-sm" data-toggle="modal" data-target="#myAdd" data-id="NO" >NO</button>
</div>
</form>
</div>
</div>
</div>
然后我使用 JScript 調(diào)用一個(gè) php 文件，它可以完美地處理 data-id 。
<script>
$(document).on('click','#getAdd',function(e){
e.preventDefault();
var per_id=$(this).data('id');
//alert(per_id);
$('#add-data').html('');
$.ajax({
url:'addLot_func.php',
type:'POST',
data:'id='+per_id,
dataType:'html'
}).done(function(data){
$('#add-data').html('');
$('#add-data').html(data);
}).fail(function(){
$('#add-data').html('<p>Error</p>');
});
});
</script>
在addLot_func.php中：
if(isset($_REQUEST['id'])){
$id=intval($_REQUEST['id']);
$reject = $_REQUEST['id'];
}
else $reject = "";
if(substr($reject,0,3) == "YES")
{
...
}
else
{
...
}
