PHP, Javascript Help.

sergep

I am very new to PHP and I have a non standard problem - maybe someone can help. I will try to elaborate it as best as I can.

There is a webpage that is accessed via PHP. (i.e. To get to the webpage I have to type http://www.whatever.com/whatever.php?)
That page contains a javascript function, lets call it JSFUNTION () that when executed performs something on the page (checks an unchecked box). To call the function, I, as a client, click on a button and JSFUNCTION() is called and the unchecked box is called.

My question is this:
Is there a way (and if there is, what is it) for me (on the client side!) to open my browser and type:

http://www.whatever.com/whatever.php?SOMETHINGHERE THAT WILL CALL JSFUNCTION.

If so, what do i type if the function name ius JSFUNCTION ()

Thanks.

Well, the absolutely easiest way to solve this would be;

http://www.whatever.com/test.php?callFunc=1

and in test.php;

if ($callFunc == 1)
print '<script language="JavaScript">JSFUNCTION();</script>';

.. I assume 😛

Yes but I have no control over the server side.
All i have control over is what i type in the address bar of the explorer/navigator.

can't I do
http://www.whatever.com/test.php?callFunc=JSFUNCTION? or something along those lines?

Thanks a lot.

No, since obviously the php script isn't written to handle a parameter called 'callFunc'. In general, JavaScript functions must be called after the page is loaded, and from within the page.

Hi!

If I understand you correctly, you need to run a specific Javascript function when the page is loaded.
Just do this:
In the BODY tag, put this:
<BODY <?php print GetCurrFunction(); ?>>

function GetCurrFunction()
{
global $func;
if (empty($func)) $ret = '';
else $ret = 'ONLOAD="'.$func.'"';

return $ret;
}

$func is the name of the function passed through the query string.

The above PHP function will need to also verify the name of the function passed to the script since someone may type whatever he wants or something will happen to the URI data and the page will behave unexpectedly.

Of course, as many have already pointed out, it is impossible to control the browser from server side, but you may use this to achieve what you need.

Best,
