Changing the text of a div

5 New Member
I'm trying to update a div based on the selection from a select. I've found many pages, including one on here that describes the way I am doing this is correct but it still fails.

I get the error "Object doesn't support this property or method" at the line document.getEle mentByID("lblDe scription").fir stChild.nodeVal ue = aPackageDescrip tions[i]. Here is the code.

Expand|Select|Wrap|Line Numbers
  1. <script language="JavaScript">
  2. var aPackageDescriptions = new Array()
  3.  
  4. aPackageDescriptions[0] = "Rollin VIP"
  5. aPackageDescriptions[1] = "Don't be late."
  6. function ShowDescription(i)
  7. {
  8.     document.getElementByID("lblDescription").firstChild.nodeValue = aPackageDescriptions[i]
  9. }
  10.  
  11. </script>
  12.     <table>
  13.     <tr>
  14.         <th>Package Plan</th>
  15.         <td>
  16.             <select name="ddlPackagePlan" onChange="ShowDescription(ddlPackagePlan.selectedIndex)">
  17. <option value="1">Test Package</option>
  18. <option value="2">Meet me at the gate.</option>
  19.             </select>
  20.         </td>
  21.     </tr>
  22.     <tr>
  23.         <th>&nbsp;</th>
  24.         <td>
  25.             <fieldset>
  26.             <legend>Description</legend>
  27.                 <div id="lblDesciption">&nbsp;</div>
  28.             </fieldset>  
  29.     </table>
  30.  
Does anyone see something wrong with this? Any help is appreciated.

<div id="lblDescipti on">&nbsp;</div>
This is actually "lblDescription ." It was a typo from copy-paste. Doesn't work with the correct spelling.

the following code works :) ... compare it to yours please ... there were some closing tags of td, tr missing, use 'getElementById ' correct, have a look at the onChange-change ;)

Hmm, I'm usually strict on the proper HTML... guess I missed that somehow. Thank you for the help, it works well now.

Hi all, I know now how to change the font name of a RTF file in a RTB control using, for example: RTextBox1.SelFontName = cmbFonts.Text I have a RTF file -created with Word- displayed in a RTB control. Whenever I change the font type during the runtime by selecting a font name from a combobox -of all system fonts, the text changes its font correctly but I loose some formatting such as a bold text and/or titles become normal text.

I needed a way to display calculated, multiple, changing values (numerical sums) as users interacted with the page, and do this without going back to the server to load the page again. What I finally settled on was <input type=button...> without an "onClick" attribute (because the purpose of the buttons was only for displaying values). It works fine except they look and act like buttons. No big deal, but is there a better way?

Hey folks, I've got a combobox (DropDown List) in a windows form application which is bound to a DataSet. It's value is set to a numeric ID. It's visible text is set to a date.
