Need Javascript to jQuery conversion

[Andy11548]

Hello, this doesn't appear to work with jQuery, I think it's Javascript. Could someone please convert this into jQuery.

 

function ShowSelection()
{
  var textComponent = document.getElementById('topicMessage');
  var selectedText;
  // IE version
  if (document.selection != undefined)
  {
    textComponent.focus();
    var sel = document.selection.createRange();
    selectedText = sel.text;
  }
  // Mozilla version
  else if (textComponent.selectionStart != undefined)
  {
    var startPos = textComponent.selectionStart;
    var endPos = textComponent.selectionEnd;
    selectedText = textComponent.value.substring(startPos, endPos)
  }
  alert("You selected: " + selectedText);
}

 

Thanks,

Andy.

jQuery is a library written in Javascript. Regular javascript will still run on your website even if your other code is jQuery.

 

And no, no one is going to convert it for you (if they have any sense).

[Andy11548]

I know that... But, how would I use it with jQuery then?

[Jessica]

You just use it...

 

What happens? What do you expect? Etc...

[Andy11548]

Nevermind, sorted that problem.

 

Now, is there a way, using jQuery I can replace text in a <textarea>?

 

Thanks,

Andy.

[Jessica]

Yes. You either use val() or html(), I think for a textarea it's the html() one.

[Andy11548]

Ok. Do I have a error with this because this doesn't work :/

 

	var textarea=$('textarea'); 
	textarea.html(textarea.html().replace('H',"111111"));

I've never seen replace, and a quick google didn't turn up anything for jQuery. Do you have firebug installed?

[Andy11548]

Nope. Do you know a way to use "replace" in jquery?

 

I'm very new to this but would like to use it.

 

Thanks for the help,

Andy.

You should install firebug and use it. It's the easiest way to debug your javascript.

 

I have never used replace, but as I said before you can use any javascript WITH jQuery. You don't do anything special to it. The code as it's written looks fine so you need to use a debugging tool to help you.

Nevermind, I sorted it out after about a hour of trying shit on google.

 

var textarea = $('textarea').val();
textarea = textarea.replace(text, '[b]' + text + '[/b]');

        $('textarea').val(textarea);
