Hi all,
I'm tearing my hair out on this!
I have a simple ASP.NET 2 page with a TextBox control, in the
PreRender I set ClientSide events:-
* * * * * * * * Response.Attrib utes.Add("oncha nge",
"javascript:ale rt('Changed');" );
* * * * * * * * Response.Attrib utes.Add("onfoc us",
"javascript:ale rt('Has Focus');");
* * * * * * * * Response.Attrib utes.Add("onblu r",
"javascript:ale rt('Lost Focus');");
In the destop browser everything is fine, all events fire as expected.
When I open the same page from a PDA running Mobile IE 5, only the
onfocus and onchange events fire, onblur never does.
The Internet Explorer Mobile Reference page tells me that these, and
only these events can be caught in the mobile browser but I can't make
it work.
Can anyone save my sanity!
Cheers,
Duncan
Some additional information that I've found from testing.
The onblur DOES work for Radio Buttons - haven't tested other controls
yet.
The onblur IS getting added as an attribute to the <input
type='text'... /control - I can see it using the getAttribute
method, and it has the correct script command attached to it.
There also appears to be a problem with the getAttribute command in
general.
According to the Internet Explorer Mobile Reference the method should
return a null if the attribute is not found, instead an exception is
thrown, but without any details attached to the error object.
Here's the JS function that I'm using to check :-
function findAttributes( control) {
try {
alert ('in findAttributes' );
//alert ('onfocus = ' +
control.getAttr ibute('onfocus' ));
alert ('onblur = ' + control.getAttr ibute('onblur') );
alert ('about to get wrongattribute' );
var attrib = control.getAttr ibute('wrongatt ribute');
alert ('got wrongattribute' );
//if (control.getAtt ribute('wrongat tribute') == null)
{
// alert ('Attribute not found');
//}
//else
//{
// alert ('wrongattribut e = ' +
control.getAttr ibute('wrongatt ribute'));
//}
controlCurrent = control;
if (control.type == 'text')
{
alert ('this is a text control');
}
else
{
alert ('this is NOT a text control');
}
}
catch(e) {
catch(e) {
alert ('Error - ' + e.description);
alert ('Error - ' + e.message);
alert ('Error - ' + e.name);
alert ('Error - ' + e.number);
alert ('Error - ' + e.toString());
}
}
Just thought you might like to know.
