Re: Behavior.renderHead stopped working after migration from 1.4 to 6.5

Hi,


try something on the lines...

@Override
public void afterRender(Component component) {
component.getResponse().write(your HTML here);
}

THANK YOU!

It was exactly what I was looking for!
Works great.



Artur

Hi,

a id=from2059--lthref=# onclick=changeDate('from2059'**, -1)\/a

ins't exactly proper JavaScript. What do you want to achieve? Apend that
HTML to component's HTML?

 Hi Guys,

 We just migrated our code to W6.5 and are very happy about it.
 Unfortunately we don't know how to fix one of the errors.

 We did a research but cannot find a solution :(

 The code adds a link before a component with some javascript:

 private class ChangeDateBehavior extends Behavior {
   [...]
 @Override
 public void renderHead(Component component,
 IHeaderResponse response) {
 if (RequestCycle.get().find(**AjaxRequestTarget.class)
 != null) {
 String javascript = var e = Wicket.$(' +
 getMarkupId()
 + '); if (e != null 
 typeof(e.parentNode) != 'undefined') e.parentNode.removeChild(e);;
 response.render(**JavaScriptHeaderItem.**forScript(javascript, null));
 }
 String tag = a id=\ + getMarkupId() +
 \href=\#\ onclick=\changeDate(' + component.getMarkupId()
 + ',  + Integer.toString(days) + )\ + txt +
 ;
 response.render(**JavaScriptHeaderItem.**forScript(tag, null));

 }

 @Override
 public void bind(Component component) {
 this.component = component;
 }

 public String getMarkupId() {
 return component.getMarkupId() + -- + id;
 }

 }


 And the error msg from the console:
 ERROR: Wicket.Head.Contributor.**processScript: SyntaxError: syntax
 error: eval - a id=from2059--lthref=# onclick=changeDate('from2059'
 **, -1)\/a


 Thanks for help in advance,
 Artur

You are of course right.

Yes, I know that is not a valid javascript but it was working somehow in 
previous releases :)
And I know that wicket execute eval on this. And this is why there is an 
error.


What I want to achieve?

I want to add html link before some wicket component.
And when clicking on that link I want to call javascript function to 
modify the text value of the component

without request to the server.

So the question is how to properly add this html snipped to the page.


Thanks for help,
Artur
