php / mysql 数据库更新后的 Javascript 弹出窗口

Question

我拥有的是在客户端签署表单后更新数据库字段的 php。这可行，但我希望它在确认用户通过单击确定签名后重定向到新页面。如果他们点击 CANCEL，它将让他们留在同一页面上。

<?php
    $username = 'joeblow';
    require_once ("/mypath/include/connnect_db.php");
?>

    <p>Please only submit this after above form is completely signed.</p>
    <form id="item_complete" method="post">
      <input name="submit" type="submit" form="item_complete"  value="Submit After Signing">
    </form>
<?php
    if(isset($_POST['submit'])) {  //if the submit button is clicked
        $complete = 'c';
        $query = "UPDATE mytbale SET mycolumn='c' WHERE username='$username'";
        mysqli_query($con,$query) or  die("Cannot Update");
        echo "<script> confirmFunction(); </script>";
    }
    require_once ("/mypath/include/disconnect_db.php");
?>
    <script type="text/x-javascript">
        function confirmFunction(){
            var r=confirm("Confirm that you have signed the form!");
            if (r==true){
              window.open("http://smartpathrealty.com/smart-path-member-page/");
              }
            else {
              }
            }
    </script> 

我的问题是 php 更新数据库后 javascript 函数没有执行。

感谢您对此提出的任何建议或意见。

<script type="text/javascript">
    function confirmFunction(){
        var r=confirm("Confirm that you have signed the form!");
        if (r==true){
          window.open("http://smartpathrealty.com/smart-path-member-page/");
          }
        else {
          }
        }
</script> 
<?php
if(isset($_POST['submit'])) {  //if the submit button is clicked
    $complete = 'c';
    $query = "UPDATE mytbale SET mycolumn='c' WHERE username='$username'";
    mysqli_query($con,$query) or  die("Cannot Update");
    echo "<script> confirmFunction(); </script>";
}
require_once ("/mypath/include/disconnect_db.php");
?>

<script type="text/javascript">


    window.onload = function(){
        <?php
            if(submitted){
                echo "confirmFunction();";
            }
        ?>
    }
</script>

您可以通过 ajax 发布表单，并在您的 php 中返回对 javascript 的响应。那就是你可以使用回调来触发新窗口。

这是一个 jquery 示例：

$.post('/myscript.php', {foo: 'bar'}).done(function (response) {

window.open(......);

});

Answer 3

我相信您使用相同的页面进行登陆和更新。您需要更新您的回声以添加 onload。

echo "<script> window.onload=confirmFunction(); </script>";

希望这是您正在寻找的。​​p>

Answer 4

试试：

if (r==true) {
    window.open("http://smartpathrealty.com/smart-path-member-page/");
}
else {
    window.location = "PAGE THAT YOU WANT"; 
}

Answer 5

问题是您使用单独的<script> 标记并在定义之前调用该函数。这两个一起工作不好。另外，我很确定<script type="text/x-javascript"> 无论如何都不起作用since it's outdated 而你想要<script type="text/javascript">

您可以执行以下操作：

上移功能并修复x-javascript：

<?php
    $username = 'joeblow';
    require_once ("/mypath/include/connnect_db.php");
?>
<p>Please only submit this after above form is completely signed.</p>
<form id="item_complete" method="post">
    <input name="submit" type="submit" form="item_complete"  value="Submit After Signing">
</form>
<script type="text/javascript">
    function confirmFunction(){
        var r=confirm("Confirm that you have signed the form!");
        if (r==true){
          window.open("http://smartpathrealty.com/smart-path-member-page/");
          }
        else {
          }
        }
</script> 
<?php
if(isset($_POST['submit'])) {  //if the submit button is clicked
    $complete = 'c';
    $query = "UPDATE mytbale SET mycolumn='c' WHERE username='$username'";
    mysqli_query($con,$query) or  die("Cannot Update");
    echo "<script> confirmFunction(); </script>";
}
require_once ("/mypath/include/disconnect_db.php");
?>
