Javascript Div不显示css中默认隐藏的输出

这是java脚本函数。我希望它使div“resultss”可见并显示输出

<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>

但它不显示结果，php代码执行时没有错误。为什么不显示任何输出

<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>

我试图将结果附加到用户提交数据的页面底部

<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>

函数myFunction（）
{
var e=document.getElementById（“结果”）；
e、 style.display=“block”；
var-molwt=；
var-nhd=；
var-nha=；
var logp=；
var属性=；
document.getElementById（'properties'）.innerHTML=“分子是：“+property+”\n\

分子量为：“+molwt+”\n\

氢键供体数量=“+nhd+”\n\

氢键受体的数量=“+nha+”\n\

logp:=“+logp+”；
}

首先将javascript函数外部的PHP代码放在id为的单独DIV中，并使此display=none，然后在显示结果时调用javascript，您可以使用display=block或display=inline block或display=flex（CSS3中新增）。使您的DIV可见。

如果我理解正确，我看不出您为“resultss”DIV分配了任何值。请尝试

e.setAttribute（“可见性”、“可见”）；“

@Nirmal我已为resultss的子元素属性分配了值

<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>
