Hi,
How to put php inside javascript?
I try (but its not working):
<?php
$htmlString= 'testing';
?>
<html>
<body>
<script type="text/javascript">
var htmlString=<?php echo $htmlString; ?>;
alert(htmlString);
</script>
</body>
</html>
tutorial that I use for that parpose: http://web-design.lovetoknow.com/Define_PHP_Variables_Inside_Javascript
Thanks
You're missing quotes around your string:
...
var htmlString="<?php echo $htmlString; ?>";
...
you need quotes around the string in javascript
var htmlString="<?php echo $htmlString; ?>";
Try this:
<?php $htmlString= 'testing'; ?>
<html>
<body>
<script type="text/javascript">
// notice the quotes around the ?php tag
var htmlString="<?php echo $htmlString; ?>";
alert(htmlString);
</script>
</body>
</html>
When you run into problems like this one, a good idea is to check your browser for JavaScript errors. Different browsers have different ways of showing this, but look for a javascript console or something like that. Also, check the source of your page as viewed by the browser.
Sometimes beginners are confused about the quotes in the string: In the PHP part, you assigned 'testing' to $htmlString. This puts a string value inside that variable, but the value does not have the quotes in it: They are just for the interpreter, so he knows: oh, now comes a string literal.
