Jquery to parse HTML in a string - php

Question

I tried searching the related posts, and having a hard time figuring out how to fix my query - I'm pretty close, any help is much appreciated (new to Jquery).
I program in PHP, and trying to pull either the HREF value from a tag, or the text. Either will work.
I basically have my HTML code in a string, might contain multiple tags, and would like to load the text of the tags into either a PHP array or variable (right now just trying to ALERT the results, I can dump it later).
My PHP Code:
<?php
$info = '<li><strong>I want this text</strong>';
echo '<script type="text/javascript">';
echo '$("document").ready( function () {';
echo 'alert($("a", $("' . $info . '")).html());';
echo '});';
echo '</script>';
?>
The above doesn't alert anything. Putting in
echo 'alert("yes")';
does work, so I'm guessing there's something basic wrong with my syntax, but 4 hours later still unable to find it! :)
Thanks in advance.

Answer 1

You aren't Javascript-escaping the quotes in your string.
Your code creates Javascript that looks like
$("<li>...<a href="http..."...")
The quotes in the attribute end the Javascript string, creating a syntax error.
You need to call json_encode.

Answer 2

SLaks has the rest of your problem. But also, it's not:
$("document").ready();
It's:
$(document).ready();
The former is a selector for a tag named <document>.

Answer 3

This should work the way you want it to:
<?php
$info = '<li><strong>I want this text</strong></li>';
?>
<script type="text/javascript">
$(document).ready( function () {
alert($("a", $("<?php echo $info; ?>")).html());
});
</script>

Answer 4

You are not closing your li Tag
$info = '<li><strong>I want this text</strong>';
should be
$info = '<li><strong>I want this text</strong></li>';

Answer 5

You should escape info. It's breaking because you've got double quotes inside of double quotes:
$info = addslashes($info);
or
$info = json_encode($info);
or just
$info = str_replace('"', '\\"');

Answer 6

Try to save the HTML is a JS variable first, then use it. Also, heredocs are your friend.
<?php
$info = '<li><strong>I want this text</strong></li>';
echo <<<END
<script type="text/javascript">
$(function(){
var HTML = '$info';
alert($('a', $(HTML)).html());
});
</script>
END;
?>

Answer 7

echo '<script type="text/javascript">
$(document).ready( function () {
var info = \''.$info.'\';
$("a").html(info);
alert(info);
});
</script>';
