Question

if(($row["status"])!="valid")
{
    $stats=$row["status"];
    echo "<script type='text/javascript'>";
    echo "alert('Your Status is $stats..Please Try Again Later...');";
    echo "</script>";
    header ("location: index.php");
}

它是php代码的一部分。如果我在标题之前使用//，javascript run ..但是当我不使用//时，它直接转到index.php。解决办法是什么？？或者是否有任何方法可以调用javascript函数来显示来自此if条件的消息？

Answer 1

在此方案中，将标题替换为 document.location.href 因此您可以显示警告框，当您单击“确定”时，它会重定向到您的index.php页面

if(($row["status"])!="valid")
{
    $stats=$row["status"];
    echo "<script type='text/javascript'>";
    echo "alert('Your Status is $stats..Please Try Again Later...');";
    echo "</script>";
    echo "<script>document.location.href='index.php'</script>";
}

你能试试吗，

        <?php 
            if(isset($row["status"]) && trim($row["status"])!="valid")
            {
                    $stats=$row["status"];
                    echo "<script type='text/javascript'>";
                    echo "alert('Your Status is $stats..Please Try Again Later...');";
                    echo "window.location.href='index.php';"; // instead php header you can use javascript location.hrfe 
                    echo "</script>";                           
            }

        ?>

try

Answer 4

您也可以尝试这样

if(($row["status"])!="valid")
{
$stats=$row["status"];
echo "<script type='text/javascript'>";
echo "alert('Your Status is $stats..Please Try Again Later...');";
echo "location: index.php";
echo "</script>";
}

如果有标题，如何在PHP中使用javascript？
