Try this:
1. Assume u have a textfield text1
2 Write an ajax behavior as follows (for a link e.g)
AjaxEventBehavior b1 = new AjaxEventBehavior("onclick"){
@Override
protected void onEvent(AjaxRequestTarget target) {
// Here access the web request for text1
}
/***
Modify the url to contain the text1 value
**/
@Override
public CharSequence getCallbackUrl() {
String otherInput =
"wicketSerialize(document.getElementById('"+text1.getMarkupId()+"'))";
return super.getCallbackUrl()+"',"+otherInput;
}
protected CharSequence getCallbackScript(boolean
recordPageVersion,
boolean onlyTargetActivePage)
{
return getCallbackScript("wicketAjaxPost('"
+ getCallbackUrl(), null, null);
}
};
