Is there any way to highlight text in TextArea, Div, Iframe and know what is highlighted? Javascript, ASP, VBScript

Is there any way to highlight text in TextArea, Div, Iframe and know what is highlighted? Javascript, ASP, VBScript

We want to be able to present a user (without using FrontPage which we have) with a textbox/Div,Iframe.

In this box they will either be able to enter text or edit text.

We do not know of any way where we could highlight text in the box and then press a button that would perhaps put HTML tags around it.

We have found a way to type text and then press a button called "Bold" that will bold the entire entry in the textbox, but not selected text.

Any ideas would be helpful.

Yes, we could use FrontPage (that we own), but we have a very simple application where the user would bold a few lines or underline them.

Thanks, Peter

Editing a text area isn't going to be much help -- how are you intending for the user to save it back? It's form data, not an HTML page. And there's no way to do ANY formatting on a textarea field. About the only thing you can do is linebreaks, and even that doesn't always work. You could always have them put in the HTML codes for the formatting they want, but that's hardly user friendly.

Use FrontPage. It's probably the easiest way. That, or Netscape Composer. They'll need to have the appropriate username/password to save the files BACK to the server though, and you have absolutely no control over what they do, and they'll have access to ANY files in that folder, and depending on how the site is set up, you could be giving them access to ALL the files on the site. This opens your site up to some very nasty scenarios -- from innocent typos to massive unauthorized changes.

Are you SURE you want to do this?

this is possible only in IE and perhaps NS6

<script>
function go() {
     var selection = document.selection.createRange().text;
     document.selection.createRange().text = '<A HREF="">' + selection + '</A>';
}
</script>

text

<button onclick="go();">click</button>

just select the text and the click on the button

hopefully you'd use this with some content management system that can ensure that this submission will not break your pages

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

 
djbusychildCommented:
Also, if you're on IE you can use the design mode which lets you do formatting, adding inserting text as if you're using those tools like frontpage or whatever.

If this is only for content management scnenrio where you have control over the browser they're using, etc... then you might want to use that feature

WE will look at the DHTML component. We do not have IE 5.5 so we cannot use the "editable" function.

We have FrontPage but users have found it somewhat cumbersome since our pages uses DIV's and Iframes so when they click on the IE Edit button that launched FrontPage it will not bring up the page they desire.

I guess the question really is: Is there a way a user can highlight select text in a paragraph using their mouse AND then have Javascript know what is highlighted so it can place an HTML tag before and after what is highlightd (after a button on a page is clicked)?

We think we have a way using some Javascript methods that allow you to search for text and then can position the cursor where you want it BUT we really rather use a highlighting method as you might in Word.

Trying to avoid activex controls. We did find a way to do this using the following ActiveX for those that are interested though (however we will not be using this since we want to avoid ActiveX controls)

<html>

<head>
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<meta name="GENERATOR" content="Microsoft FrontPage 4.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<title>New Page 2</title>
</head>
<script language="vbscript">
     Sub OpenURL()
          oEditFrame.LoadURL Trim(document.all.textboxURL.value)
     End Sub
     Sub UpdateHiddenTextbox()
          document.all.oTextarea.value = oEditFrame.DocumentHTML
     End Sub
</script>


<body>
<!-- <form id="frmEditHTML" name="frmEditHTML"> -->
<p>
<OBJECT id="oEditFrame" style="LEFT: 0px; TOP: 0px" name="oEditFrame" classid="clsid:2D360200-FFF5-11D1-8D03-00A0C959BC0A"

     <PARAM NAME="SnapToGridY" VALUE="50">
     <PARAM NAME="BrowseMode" VALUE="0">
     <PARAM NAME="UseDivOnCarriageReturn" VALUE="0">
</OBJECT>
</p>
<p><input type="text" size="78" name="textboxURL" value="">&nbsp;&nbsp;
<input type="button" value="Open" name="buttonOpen" onclick="OpenURL()">
<input type="button" value="Submit Changes (Not Active Yet)" name="buttonSubmit" onclick="UpdateHiddenTextbox()"></p>
<p>
<br>
<center><h3>For demo find your desired page and then click the open button</h3></center>
<br>
<b>Highlight text you wish to change</b><br>
<b>Bold</b>&nbsp<i>Control + B</i><br>
<b>Italic</b>&nbsp<i>Control + I</i><br>

<br>
<b>Line Break</b>&nbsp<i>Shift + Enter</i><br>
<b>New Paragraph</b>&nbsp;<i>Enter</i><br>
<p>hidden textarea</p>
<p><textarea id="oTextarea" name="oTextarea" rows="8" cols="75"></textarea></p>
<!-- </form> -->

</body>

</html>

We are playing around with some other JavaScript functions at the moment.

Actually since we do not want to use ActiveX, a user posted this on the NewsGroups. Hope this helps someone as it did me.

pacumming , you didn't read my comment. I had alraedy posted code that lets you put tags around text selection

pacummingAuthor Commented:
Yes you are correct djbusychild. The reason I lost sight of that was because you only had one word in the textarea ("text"). Therefore I did not know you could highlight multiple words. I added multiple words in the textarea, highlighted a few, and it did indeed perform as you suggested.

Thanks for correcting me.
