<div id="txt"></div><br><br>"""<br>print "html: "+pid_data+"<br>"<br>print """<br></body><br></html>"""<br><br>
Output of above code is the following, which is just the PID of the Python CGI itself at runtime, displayed via javascript and via HTML.<br>Hello World!<br><br>
<div id="txt">js: 1308</div><br>
html: 1308<br><br>

</div>The problem is that you're not passing the data at all. You never<br>
interpolate the pid_data value into the string(s) constituting your<br>
embedded JavaScript (though you did do it just fine in the pure HTML).<br>
The Python variable `pid_data` is not somehow magically accessible to<br>
JavaScript; you must explicitly insert its value somewhere.<br>
<br>

<br>
Change that line to:<br>
<body onload="showPID("""+pid_data+""")"><br>
<br>
As an example, if the PID happens to be 42, then the outputted<br>
fragment will end up being:<br>
<body onload="showPID(42)"><br>
<br>
As a sidenote, I would recommend using something higher-level than the<br>
`cgi` module. Python has an abundance of web frameworks and templating<br>
languages; take your pick.<br>
<br>
