php in javascript

[juicy]

I have create a checkbox,call getS function in onclick event. I append
value of variable output with value $text. It works well but when I
changed value of $text to a paragraph of text, it will occur error on the
page. Please advise. Thanks.

<script language = "javascript ">
<?php $text = "testing"; ?>

function getS (id){
var output = "";
if (document.getEl ementById("id") .checked)
{
output = output + <? echo $text; ?> ;
}}
</script>

Re: php in javascript

You need to learn about the request resonse model. php is run to
produce html(& javascript) which is then sent to the browser. The
broser then runs the html (& javascript). So your code will be
delivered to the browser as

<script language = "javascript ">

function getS (id){
var output = "";
if (document.getEl ementById("id") .checked)
{
output = output + testing ; // <- error testing is not a variable.
}}

</script>

Sorry, I have mistype the code, it should be

output = output + "<? echo $text; ?>";

if I assign $text a short text, it will OK. But if $text is a paragraph/
multiple line of string, it will occur error on the page.

Please give idea on what has happen..
Thanks.

Re: php in javascript

You need to have valid javascript code, which is not happening when you
have several lines in text. You want to get to
output +="Line1\nLine2 \nLine3\n"; // += is the same as a=a+
so
<? function jsencode($str)
{
return implode('\n',ex plode("\n",$str )); //Could use str_replace -
probably better.
}?>

output+="<? echo jsencode($text) ; ?>";

Looks like a javascript problem to me. Try a javascript newsgroup.

But why if I pass the paragraph of text from onclick event on a checkbox,
to show it on textarea, it can perform well although the text is a
paragraph.

<td ><input type=checkbox name="chksur2"
onclick="getSur charge('duties' ,this.value)" value="<? echo $strSurcharge1;
?>">

<script language="JavaS cript">
function getSurcharge(id , value)
{
document.getEle mentById(id).va lue= value;
//to show text on a textarea
}
</script>

<?php $strSurcharge1 = " (paragraph of text) ";
?>
