Parsing textarea content

[bigodines]

Hello guys!

I'm creating a simple editor for a customer Its basically many fields that will populate dinamically a textarea. The insertion is Ok. the problem is when the user enters in "edit mode" to change something in the inserted content.

I need to parse the textarea content and then split it into the other form fields

for example... my textarea contains:

<!-- model -->1<!-- /model -->
<!-- header -->img de cabecalho<!-- /header -->
<!-- content --> something here... <!-- /content -->
<!-- link1 -->link 1<!-- /link1 -->

Each <!-- XXX --> corresponds to something that must be extracted from this textarea

my questions question are:
1 - how to read the content of a textarea and manipulate it's data? (to remove the metadate and pre-loaded values
2 - how to get everything between <!-- link1 --> and <!-- /link1 -->

thanks in advice.

Hi,

This is normally something done in a serverside language (parsing and replacement) such as PHP. Any reason you're doing this in Javascript?

yes. It's a plugin to be installed with a WYSIWYG editor...

I've found this solution. It may not be the best. but it works.

	function parseMe() {
		content = document.getElementById("introtext").value;
		
		try {
			model = content.substring(content.indexOf("<!-- model -->")+14,content.indexOf("<!-- /model -->")+15);
			content = content.replace(content.substring(content.indexOf("<!-- model -->"),content.indexOf("<!-- /model -->")),"");
		} catch (er) {
			alert('ocorreu um erro ao capturar os dados do template');
			return false;
		}
		document.getElementById("introtext").value = content;
	}
