View Full Version : Form Data and iFrames

09-27-2011, 03:11 PM
I am trying to get around using server side scripting for an issue on a webpage. I have a basic html form like this:

<FORM NAME="myform" ACTION="" METHOD="GET">Enter something in the box: <BR>
<INPUT TYPE="text" NAME="inputbox" VALUE=""><P>
<INPUT TYPE="button" NAME="button" Value="Click" onClick="testResult (this.form)">

I know I can use JavaScript to capture the data like this:

function testResults (form) {
var TestVar = form.inputbox.value;
alert ("You typed: " + TestVar);

Instead of alerting it, can I save the data in an iframe? Will it stay there once they leave the page? I want the iframe to eventually contain info from lots of people's answers.

I am wanting to simulate saving the answers to a text file on the server.

simply, no.

You can't access data from multiple users without server side code. Each user can only affect what is happening in their browser on their computer.
Even a "simulation" of writing to the server from multiple users would require accessing the global application variable (i.e. global.asa in asp) which would still require sever side scripting :(

Well, that is not what I wanted to hear but it does make sense. Thank you.

Actually you could use a cloud service as this one to spare you the server side work in a prototype:
