Hi Michael,
thanks for your help, but it doesn't work yet. My code:
TextField myField = new TextField("text");
myField.setOutputMarkupId(true);
myField.setOutputMarkupPlaceholderTag(true);
add(myField);
private final class MyLink extends AjaxFallbackLink
{
public void onClick(AjaxRequestTarget target)
{
onShowForm(target);
target.appendJavascript("getElementById('"+myField.getMarkupId()+
"').focus()");
}
}
Is there something obviously wrong? Correct Javascript syntax and
semantic? Is there an alternative "wicket" approach so that I don't have
to use Javascript myself?
Thanks for help
Philipp
use target.(pre|append)Javascript if you want additional JS executed
before/after doing the wicket-ajax stuff
if you only want to set the focus (without any ajax involved), don't use
ajaxlink, use e.g. a simple WebmarkupContainer
hth,

Dear all,
I try to show and focus on a text field when clicking on a link. The
focus however doesn't work. I tried to follow an example in cwiki
(http://cwiki.apache.org/WICKET/calling-javascript-function-on-wicket-components-onclick.html)
but I somehow do something wrong. I tried to add some javascript
attribute via AttributeAppender, but then I get a null pointer exception
in onClick ("target is null"). When I comment that line out (so don't
add the Attribute), everything works fine except that focus doesn't work.
Any help appreciated.
Thanks a lot
Philipp
Here's my code:
in a WebMarkupContainer:
link.add(new AttributeAppender("onClick", new
Model("getElementById('"+textfield.getMarkupId()+ "').onFocus();"), ";"));
in my custom Link Class:
public void onClick(AjaxRequestTarget target)
{
showFormThatContainsTextField(target);
}
void showFormThatContainsTextField(AjaxRequestTarget target)
{
// toggle the visibility
...
// redraw the add container.
target.addComponent(this);
}
