you would have to recreate the the javascript function in php then pass the vars it needs from the html to it to get the output

But my web page  source code is in string.

how can i call JavaScript function in it?can you tell me how to do that?

[ratcateme]

you can't call the js function in php the only way is to create a function in php that does what the js function did like this

function js_function($url){
//do what the js did to the url
return $url;
}

the only other way is to load the page with the cURL request and have the user press the link so the javascript will run in the users browser

I have yet to find php code that compiles JavaScript. That's like asking vb to compile flash. What does the JavaScript function do anyways? For example, are you grabbing the content from the remote site and presenting the code to your webpage to be viewed in a browser as well?

I think you might be a little confused or I am.

If your trying to get php to exicute the javascript function that cant be done.  PHP is exicuted before the browser even sees anything javascript is run at the server.

If your trying to get PHP to do what the JavaScript was doing then your going to have to post the entire JavaScript function.

sir,

as i have mention above.i am displaying webpage from my php scrip using curl.

now on this page there is one link which when clicked call JavaScript function which i have mention in my last to second reply.

i want to call this JavaScript function automatically once my page loaded on browser through curl.

[ratcateme]

so you want to run the js function on the clients browser when they have loaded the page?

 

Scott.

[unkwntech]

then you want to find the line with the <bdoy> tag and add in an onLoad i suggest:

<?php
$lines = expode('\n', $data);
foreach($lines as $line)
{
   if(preg_match('<body', $line))
 {
	if(preg_match('><', $line)) //This is not required but some bad devs will do <body...><newTag... and we'll want to catch that if the site you are taking from does not do that then, remove this condition.
	 {
		preg_split('/>[abcdefghijklmnopqrstuvwxyz0123456789\t]*</i', $line);
	 }
	$line = preg_replace('>', '', $line) . ' onLoad="functionName >";';
    }
}
?>

This need improvement and is not tested.

Scott.

sir,

i am not getting what you want to say.please can you justify your comments in bit detail??

[ratcateme]

if you set a onload="js_function()" in the <body> tag so it looks like this <body onload="js_function()"> when the page is fully loaded images and everything (except flash i think) it will run js_function().

i think a better way than all those preg_replace() you could just use str_replace()

echo str_replace("<body>","<body onload=\"js_function()\">",$html_from_curl);
