Re: [flexcoders] Re: Updating renderer properties

[Aaron Hardy]

Thanks for sharing your thoughts and examples. In my case I decided to pass
in a model with a property into the renderers.  The model is passed into the
renderer by specifying it as a property value in the renderer class
factory.  The model doesn't ever get replaced after that, but the property
inside the model does.  I can't say any solution really strikes my fancy,
but this seemed to be the most appropriate.

Again, thanks for the discussion.

RE: [SPAM] [flexcoders] Properly display html entities in datagrid

[Tracy Spratt]

So I understand that the data is not html, but just has some html encoded
entities in it correct?

 

You can manually convert the data yourself.  Regular expressions are
probably a better way to go, but I do not use them enough to be comfortable
with them, and use a function like this:

public static function htmlDecode(s:String):String

{ 

  s=s.split("&").join("&"); 

  s=s.split(""").join("\"");

  s=s.split("'").join("'"); 

  s=s.split("/<").join("");

  s=s.split(">").join(">"); 

  return s;

}

 

The replace() function might be better as well.

Subject: [SPAM] [flexcoders] Properly display html entities in datagrid

 

  

Hello everyone,

I've recently come across a problem at work where in much of the data we're
getting is showing up in the data-grid as:

The tags show and the " quotes " aren't converted!

This is a problem and I'd like to be able to display this correctly:

The tags show and the " quotes " aren't converted!

We don't necessarily have too much control over the data, so I'm not
entirely sure how/why the items are coming up like this when some items come
up with characters like < > in them. For instance: "This is an item > This
is another item > In a breadcrumb trail". This shows up correctly. I'm not
sure what exactly should be done. But again since we don't have
control/access to the data, it cannot be changed or substituted or converted
to other formats. I thought of using htmlText but that doesn't work if I
have data like the "breadcrumb string" above because it interprets the '<'
characters as opening tags and doesn't render the entire data:

[Bindable]
private var testString:String = "6  "seven"";

 
 

Any suggestions would definitely be appreciated, I'm sure I'm probably not
the only person that's come across this :( But basically we just need all
characters like: < to be converted to '<' and & to be '&' meanwhile
data that was encoded properly, data that has '<' and '&' showing up
correctly should be left the same.

Thanks in advance for any help :)
