Inserire codice php dentro al javascript

luigi777 · 10 Mar 2015

Salve, come faccio inserire il codice:

PHP:

<?php echo $bb->bbcode_complete(htmlspecialchars_decode($content)); ?>

in questa pagina html e javascript:

PHP:

<!DOCTYPE html>
<html lang="it">
	<meta charset="utf-8">
	<link href="../css/f.css" rel="stylesheet" type="text/css">
	<link href="css/preview.css" rel="stylesheet" type="text/css">
	<link href="../css/extra.css" rel="stylesheet" type="text/css">
    <body onload="initializeMainDiv();">
	<div id="f">
    <div id="mainDiv">
	</div>
	</div>
    </body>
    <script>
	function initializeMainDiv() {
        document.getElementById("mainDiv").innerHTML = "" +
		window.opener.document.pages.content.value;
    };
	</script>
</body>
</html>

che questa pagina mi fa come anteprima che e stata chiamata dalla madre.

come posso inserire il codice php a javascript ?

grazie mille e buona serata.

PHP:

<?php
session_start();
include("inc.php"); 
include("admin_mod.php"); 
?><!DOCTYPE html>
<html lang="it">
	<meta charset="utf-8">
	<link href="../css/f.css" rel="stylesheet" type="text/css">
	<link href="css/preview.css" rel="stylesheet" type="text/css">
	<link href="../css/extra.css" rel="stylesheet" type="text/css">
    <body onload="initializeMainDiv();">
	<?php 
		$bb = new BBCode();	
		$content = '<div id="f"><div id="mainDiv"></div></div>';
		echo $bb->bbcode_complete($content);
	?>
    <script>
	function initializeMainDiv() {
        document.getElementById("mainDiv").innerHTML = "" +
		window.opener.document.post.content.value;
    };
	</script>
</body>
</html>

Ho provato cosi.. ma non mi fa più il rendering del bbcode.. uso questa classe:

e buona serata.

vediamo se un principiante riesce ad aiutarti ! .. secondo me a parte il tag <head></head> che manca totalmente ... dovresti invertire .. prima lo script java e poi chiudere il tag </head> e poi lo script php ( intendo il secondo ) .. altrimenti lui prima esegue lo script php che richiama il bbcode e poi inizializza la funzione del maindiv ... che a quel punto non serve a niente in quanto dovrebbe includere il codice php che hai gia chiamato !

ciao. scusa il ritardo,
lo script senza il bbcode ovvero senza altro codice php funziona..
l'esempio lo presto da qui:
https://www.ibm.com/developerworks/community/blogs/hazem/entry/accessing_parent_window_elements_from_child_window_in_javascript5?lang=en

questo è il mio codice MOD.

Codice:

function popup_window(link,largo,alto,nome){
msg=open(link,nome,"toolbar=no,directories=no,menubar=no,width="+largo+",height="+alto+",resizable=no,scrollbars=yes,left=10,top=10");
}

PHP:

<p><textarea name="content" cols="100" rows="30"><?php if(isset($_POST['content'])){echo $_POST['content'];}?></textarea></p>
			<p><a href="#" onclick="javascript:popup_window('popup_post.php',500,600,'preview');">Anteprima</a></p>

e questo e la child:

PHP:

<?php
session_start();
include("inc.php"); 
include("admin_mod.php"); 
?>	<!DOCTYPE html>
	<html lang="it">
	<meta charset="utf-8">
	<link href="../css/f.css" rel="stylesheet" type="text/css">
	<link href="css/preview.css" rel="stylesheet" type="text/css">
	<link href="../css/extra.css" rel="stylesheet" type="text/css">
    <body onload="initializeMainDiv();">
	<?php 
		$bb = new BBCode();	
		$content = '<div id="f"><div id="mainDiv"></div></div>';
		echo $bb->bbcode_complete($content);
	?>
    <script>
	function initializeMainDiv() {
        document.getElementById("mainDiv").innerHTML = "" +
		window.opener.document.post.content.value;
    };
	</script>
</body>
</html>

come mai se metto:

PHP:

<?php 
		$content = '<div id="f"><div id="mainDiv"></div></div>';
		echo $content;
?>

funziona .. e mi permette solo l'html invece dei miei codici personalizzati non funziona?

grazie mille e buona settimana.
