how to pass the value of html value to php without sumbit??

penny336

e.g.
there is a form
<form name="addform" method="post" action="acti.php" onSubmit="return validate()">
<table width="100%" border="0" cellspacing="1" cellpadding="3">
<tr>
<td width="20%" class="items">
<?php getLabel($lang, 1, "Position Name") ?>
</td>
<td bgcolor="#CCCCCC" colspan="3"><font face="Arial, Helvetica, sans-serif" size="2">
<input type="text" name="job_name" value="<?php if ($id) echo $row->job_name; ?>" size="60" maxlength="255">
</font></td>
</tr>
<input type="submit" name="Submit" value="getLabel($lang, 1, "Save") ?>">
<input type="button" name="Submit" value="<?php getLabel($lang,1,"Preview") ?>" onClick="<?php printf("javascript:popup('job.php?id=%s','astri_jobWin')", $row->job_no); ?>;">
</table>
</form>
normal after submit, php code get value of variable $job_name
can i get the value of job_name without submit.
cos i want to use javascript:window.open to preview the form.

hi,
using javascript you can
consider this example:

you have a form and:

<a href="#" onclick="document.forms[0].submit()">submit!</a>

this.
submits the form

so I guess your button to preview the form will do this as well

you can read out the values of the form using opener.top.document in the popup page to access the contents of the page that called it. beware, this will not work on some browsers.
Try the following 2 pages:
readform.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
	<head>
		<script type="text/javascript">
			function doPopUp()
			{
				window.open( "popup.html", "mypopup",'toolbar=no, \
					location=no, directories=no, \
					status=no, menubar=no, scrollbars=yes, resizable=yes, \
					copyhistory=no,width=600,height=450' )
			}
		</script>
        <style type="text/css">
            <!--

        -->
    </style>
    <title>Read Form</title>
</head>
<body>
	<form id="myform" name="myform">
		Enter Text: 
		<input type="text" size="40" name="mytext" id="mytext" />
		<p>
		<input type="Button" value="Check" onClick="doPopUp()"/>
		</p>
	</form>
</body>
</html>

and popup.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
    <head>
        <style type="text/css">
            <!--
			span#output {
				font-weight: bold;
				color: #f00;
			}
            -->
        </style>
		<title>My Popup</title>
    </head>
    <body>
		<p>
			You entered: <span id="output"></span>
			</p>
		<script>
			v = opener.top.document.getElementById('mytext').value
			document.getElementById('output').innerHTML = v
		</script>
    </body>
</html>
