Automatically click a html button

**ronverdonk** · Mar 4 '08, 04:27 PM

Welcome to the Scripts.

Please enclose any code within the proper code tags. See the Posting Guidelines on how to do that.

This is a JavaScript / DHTML question, so I will move this thread over to the JavaScript forum.

I am new to web development. I developed a simple html page with submit button which calls a php script once clicked. Following snippet show the scenario.
[code=html]
<html>
<body>
<br>
<form method="post" action="handles cen.php">
<p style="font-family:helvetic a;font-size:14px">
<BR><BR>
<INPUT TYPE=SUBMIT NAME="SUBMIT4" VALUE="Get Statistics">
</P>
</FORM>
</BODY>
</HTML>
[/code]
I need to add the functionality that "SUBMIT4" button is automatically clicked after certain time (10 secs e. g) repeatedly. Any idea to do this will be greatly appreciated.

The thing which you want to achieve can be achieved by other ways too, but if you want do that by auto-submitting, then add function autoSubmit(10) to the onload attribute of body tag.
And following to the <script> tag.[code=javascript]var t = 0;
function autoSubmit(sec) {
if (t<sec) var wait = window.setTimeo ut("autoSubmit( "+sec+")", 1000);
else document.forms[0].submit();
t++;
}[/code]
Give it a try, tell me if it works...

hi ...

another possibility would be to use the setInterval() method:

[CODE=javascript]
function submit_form() {
document.forms[0].submit();
}

function autoSubmit() {
window.setInter val(submit_form , 10000);
}[/CODE]
kind regards

I have multiple buttons in the html form. Is is also possible to "set" a specific button? In php script, i am checking that through if(isset($_POST['SUBMIT4'])) condition.

Best regards,
Amir

Hi,

Here is structure of HTML page with single form and multiple button

Code:

<html> 
        <body> 
 
        <form method="post" action="handlescen.php"> 
<p style="font-family:helvetica;font-size:14px"> 
        Select the scenario to start 
        <select name="scenario"> 
</select> 
<BR><BR> 
<INPUT TYPE=SUBMIT NAME="SUBMIT1" VALUE="Start!"> 
<INPUT TYPE=SUBMIT NAME="SUBMIT2" VALUE="Stop!"> 
<INPUT TYPE=SUBMIT NAME="SUBMIT3" VALUE="Back"> 
<INPUT TYPE=SUBMIT NAME="SUBMIT4" VALUE="Get Statistics"> 
</P> 
</FORM> 
</BODY> 
</HTML>

I am handling the different button clicks in following Handlescen.php file.

Code:

<?php
ob_start();
?>
<html><body>
<?php

if(isset($_POST['SUBMIT1'])){

}

if(isset($_POST['SUBMIT2'])){

}

if(isset($_POST['SUBMIT3'])){

}
if(isset($_POST['SUBMIT4'])){
  // show some results
}
?>
</body></html>

Once SUBMIT4 button is clicked, I want to enable automatic clicking of button4 after evering 10 seconds. It may look bit weird requirement but I still want to give it a try.

Regards,
Amir

Try this...
[php]<html>
<head>
<?php
if (isset($_GET['auto_submit']))
echo "<script>
function autoSubmit() {
-------- //CODE GIVEN ABOVE//MAKE SURE YOU ADD SLASHES!
}
<script>";
?>
</head>
<body<?php
if (isset($_GET['auto_submit']))
echo " onload=\"autoSu bmit()\"";
?>>
<form method="post" action="handles cen.php">
<p style="font-family:helvetic a;font-size:14px">
Select the scenario to start
<select name="scenario" ></select>
<br><br>
<input type=submit name="submit1" value="start!">
<input type=submit name="submit2" value="stop!">
<input type=submit name="submit3" value="back">
<input type=submit name="submit4" onclick="addget ();" value="get statistics">
</p>
</form>
</body>
</html>[/PHP]
handlescen.php
Redirect from here to the required php file.
[PHP]<?php
ob_start();
if(isset($_POST['SUBMIT1'])){
header("locatio n:abc1.php");
}

if(isset($_POST['SUBMIT2'])){
header("locatio n:abc2.php");
}

if(isset($_POST['SUBMIT3'])){
header("locatio n:abc3.php");
}
if(isset($_POST['SUBMIT4'])){
header("locatio n:handlescen.ph p?auto_login");
?>[/PHP]

BTW: both snippets are from same file?

And for the submit problem, dynamically change the action value of the form when you click on a submit button. Concat a get parameter to the action, different for all the submit buttons.

Thanks hsriat,

I tried your proposed code but it does not seem to work. Instead it prints following text on webpage
[HTML]function submit_form() { document.forms[0].submit();}func tion autoSubmit() {window.setInte rval(submit_for m, 10000);}"; ?> >[/HTML]

To rule out the multiple line string problem, i wrote the complete text in single line.

Code:

<html>
        <head>
        <?php
        if (isset($_GET['auto_submit']))
            echo "<script = \"text/javascript\"> function submit_form() { document.forms[0].submit();}function autoSubmit() {window.setInterval(submit_form, 10000);}</script>";
        ?>
        </head>
        <body<?php
                if (isset($_GET['auto_submit']))
                  echo " onload=\"autoSubmit()\"";
                ?>
        >
        <br>
        <form method="post" action="handlescen.php">

<INPUT TYPE=SUBMIT NAME="SUBMIT1" VALUE="Start!">
<INPUT TYPE=SUBMIT NAME="SUBMIT2" VALUE="Stop!">
<INPUT TYPE=SUBMIT NAME="SUBMIT3" VALUE="Back">
<INPUT TYPE=SUBMIT NAME="SUBMIT4" onclick="addget();" VALUE="Get Statistics">

</FORM>
</BODY>
</HTML>

Please let me know if you see some problem in here

Best regards,
Amir
