attaching a custom event to a tabl cell

MuadDubby · Nov 5, 2004

Anyone know how I can create a custom event and then attach it to a table cell (TD)?

I'm pretty sure I have to use the public:event code for this, but I'm kind of stumped.

Here's the code I have so far:

Code:

<html>
<head>
<public:event id=myEvent name=onmyevent />
</head>
<body>
<table width="215" border="1" cellspacing="7" cellpadding="0">
   <tr height="48">
     <td>
       &nbsp;&nbsp;&nbsp; Maintenance Menu
     </td>
   </tr>
   <tr height="26.5">
     <td class="TDRegularImage" onclick=alert("hello1")>
       &nbsp;&nbsp;&nbsp;&nbsp;<b>P.O. Table </b>
     </td>
   </tr>
</table>
</body>
</html>

This displays a simple table, and clicking on cell #2 displays a message. I want to be able to display the message by reacting to 'onmyevent' instead of 'onclick'. Any ideas?

Don't worry about how the event will get fired; I'm actually embedding the browser control in a VB form and firing the event from the form itself.

Thx in advance,

If you're firing the event yourself, then surely all you would need to do would be:

Code:

<td class="TDRegularImage" onmyevent="alert('hello');">

Hope this helps,

Hi Billy

Tried that. Unfortunately, the custom event apparently has to be declared somewhere. When I tried to do something like that, I got an error saying that the object did not exist.

Here's what I am doing in VB (I hope your familiar with it). Create yourself a form and put a browser and and a button it. Then save the above HTML code into C:\temp\temp.html.

Code:

Private Sub Form_Load()
    WebBrowser1.Navigate2 "C:\temp\temp.html"
End Sub

Private Sub Command1_Click()
    Dim doc As HTMLDocument
    Set doc = WebBrowser1.Document

    ' the following works, because I'm firing the onclick
    ' event on the second cell
    doc.body.children.Item(0).cells.Item(1).FireEvent ("onclick")
    ' the following does not work, and I get an error
    ' saying that the argumant supplied ("onmyevent") 
    ' is invalid.
    doc.body.children.Item(0).cells.Item(1).FireEvent ("onmyevent")
    
End Sub

I think the public:event syntax you show is for HTCs (HTML Components) only. See here for more info:

So it's possible that you cannot create your own events on the fly without using HTCs... Which kind of restricts which browsers this would work in, too.
