Curious : Form processing using plain HTML

Karl Blessing · Jul 17, 2001

At most times I am using serverside code, or applications to process a form submission but I was curious, since forms is a part of standard HTML, how does standard html decode or process a form submission? (or any clientside method for that matter) Karl Blessing aka kb244{fastHACK}

no I mean actually processing it, for example, if I had

(a basic way of how I would generally do it)

Code:

<Form action=&quot;somewhere.asp&quot; method=&quot;post&quot;>
  <input type=&quot;hidden&quot; name=&quot;yname&quot; value=&quot;karl&quot;>
  <input type=&quot;text&quot; name=&quot;ytext&quot;>
  <input type=&quot;submit&quot; value=&quot;Send info&quot;>
</form>

then on the somewhere.asp I would do

Code:

...
<%
Response.write &quot;<Center> Hello &quot; & Request.Form(&quot;yname&quot;) & &quot; how are you </center>&quot; & vbcrlf & &quot;<BR>&quot;
Response.write &quot;you typed in : &quot; & Request.Form(&quot;ytext&quot;)
...
%>

question is, in regular HTML or javascript, how do I process information sent to a page. Rather than using Request.Form of a serverside language. Karl Blessing aka kb244{fastHACK}

Hello,
Vitus is right.
Some examples to play with:
<HTML>
<HEAD>
<TITLE> Simple HTML Form </TITLE>
<script language="JavaScript">
function somefunction(){
alert(document.forms[0].yname.value);
alert(document.forms[0].ytext.value);
alert(document.forms[0].elements[2].value);
}
</script>
</HEAD>

<BODY>
<Form method="post" enctype="text/plain" onsubmit="somefunction()">
<input type="hidden" name="yname" value="karl">
<input type="text" name="ytext">
<input type="submit" value="Send info">
</form>
</BODY>
</HTML>

or using action=mailto

<Form action="mailto:you@some.com" method="post">
will send query string yname=karl&ytext=test to specified e-mail.

or
<Form action="mailto:you@some.com" method="post" enctype="text/plain">
will send formmated output to the specified e-mail:

yname=karl
ytext=test

<Form action="mailto:you@some.com?Subject=Welcome" method="post" enctype="text/plain">

will change the default subject "Form posted from <browser>"

still thats like clientside validation, not target processing, how can you in javascript or HTML, on the target page, process the passed information, for example if I wanted a big RED caption on the target page with the passed information. Karl Blessing aka kb244{fastHACK}

got ur point, (at last! X-))
but do u mean processing on the other page or on the same ?
if on the same then u shuld use layers (innerHTML for ie4+, nn6 & document.layers.layername.document.write('some_Value_From_Some_Form') for nn4x)
if u're talkin about processing it on the other page then i, cant say about post method, but get is do-able (location.search & stuff)
am i on the right way?? regards, vic
