Question

这是java脚本函数。我希望它使div“resultss”可见并显示输出。

但它没有显示结果，PHP代码执行没有错误。这是不显示任何输出的。

我正在尝试将结果附加到用户提交某些数据的同一页面的底部

<script>
function myFunction()
    {
    var e = document.getElementById("resultss");
    e.style.display = "block";
    <?php

    $format =  $_SESSION["ff"];
    $ses_id = $_SESSION["id"];
    $filena = $_SESSION["filename"];
    //$pubquery = $_SESSION["pubquery"];
    $result1 = shell_exec("C:\Python27\python.exe C:\Python27\PredictoR\Model_desc.py $format $ses_id $filena  2>&1");
    $properties = explode(" ", $result1);
    if($properties[0] == 1)
    {
    $property = "Substrate";
    } else  {
    $property = "Non-substrate";
    }
    $molwt = trim(preg_replace('/\s+/', ' ', $properties[1]));
    $nhd = trim(preg_replace('/\s+/', ' ', $properties[2]));
    $nha = trim(preg_replace('/\s+/', ' ', $properties[3]));
    $logp = trim(preg_replace('/\s+/', ' ', $properties[4]));

    ?>

    var molwt = <?php echo json_encode( $molwt); ?>;
    var nhd = <?php echo json_encode( $nhd); ?>;
    var nha = <?php echo json_encode( $nha); ?>;
    var logp = <?php echo json_encode( $logp); ?>;
    var property = <?php echo json_encode( $property); ?>;

    document.getElementById('properties').innerHTML="Molecule is : "+property+"  \n\
    <br/>Molecular weight is : "+molwt+" \n\
    <br/>No. of hydrogen bond donors = "+nhd+"\n\
    <br/>No. of hydrogen bond acceptors = "+nha+"\n\
    <br/>Log P :  = "+logp+";

    }
</script>

将PHP代码放在javascript函数之外的单独的DIV中，并且首先使这个display = none然后当你的显示结果调用javascript并且你可以使用display = block或display = inline-block或display = flex（New在CSS3）。使你的DIV可见。

Div不显示在css中默认隐藏的输出
