I’ve got some data in a weblog and I want to create a simple JavaScript array in one of my templates. However I can’t seem to figure out how to get JavaScript to accept the ee tag.

To debug this I created the following simple template to test this (which does nothing)  :ohh: .

[removed] 
   {exp:weblog:entries weblog="myweblog" }
       alert('{my_weblog_entry}');
    {/exp:weblog:entries} 
[removed]

But if I just change the contents of the JavaScript alert (below) it works 😊 :

[removed] 
   {exp:weblog:entries weblog="myweblog" }
       alert('WTF');
    {/exp:weblog:entries} 
[removed]

In this example the weblog entries tag loops through all my posts and displays the alert message for each weblog entry. So there is something about

alert('{my_weblog_entry}');

that is causing a problem.

I’ve seen posts in this fourm that suggest inserting line breaks before/after the curly brackets or putting $conf[‘protect_javascript’] = “n”;  in the config.php file but none of these seem to work OR I don’t know how to implement them in my example.

So what would I need to do to get

alert('{my_weblog_entry}');

to display my weblog content?

if you view source in your browser, what is actually output by EE when you’re using the {my_weblog_entry} tag in the script block?

Shot in the dark here, but have you tried having your weblog tags outside of your script tags?

{exp:weblog:entries}
[removed]
alert('{my_weblog_entry}');
[removed]
{/exp:weblog:entries}

Appears this form strips out the > script type=“text/javascript” < wrapper and substitutes [removed]...anyway..

I changed the alert(’{my_weblog_entry}’); to document .writeln(’{my_weblog_entry}’); to better see what was going on inside the page. Here are the results:

With document .writeln(”{my_weblog_entry}’); the pages sources shows this:

document .writeln("Lorem Ipsum");

document .writeln("Finibus Bonorum et Malorum");

document .writeln("Nemo enim ipsam");

The weblog entries (latin text) are being passed as expected but the paragraph elements are NOT in my weblog entry so they being inserted somewhere. Even with the elements the entry should be displayed. Seems that JavaScript is disabled.

If I modify the JavaScript write statement to: document .writeln(‘WTF’); the text is displayed in the browser as expected.

Go figure ❓

This is crazy. I’ve tired numerous configurations and can’t figure out why an EE parsing tag prevents JavaScript from executing?

What is going on?

if the tags are the cause of the problem, you can get EE to not add these to your text by changing the format of the custom field from ‘xhtml’ to ‘none’.

That’s it 😉

Changed the custom field to none and it worked.

Thanks

Upon closer inspection EE still seems to have a hand in manipulating one of my custom fields that contain a URL like www .mydomain.com. When EE parses the URL custom field (not just into my JavaScript, but anywhere in a template) it wraps it in an anchor tag so it comes out like:

<a href="http://www.mydomain.com">http://www.mydomain.com</a>

despite the fact the custom field has been set to none.

Is there a way to override this?

Thanks,
Chris
BTW: I had to put a space in my example above or EE changed it to an anchor in this post.

the setting you’re looking for is “Automatically turn URLs and email addresses into links?”.  This is located in Admin > Weblog Management > Edit Preferences > Weblog Posting Preferences.
