Re: IE call wicket twice from JS
Thanks for you reply.
Unfortunately jQuery did't help.
My new code:
String script = $('#corruptedPackagesDiv').scroll(function(){ //
+ var var1 = $('#corruptedPackagesDiv').scrollTop(); //
+ var var2 = $('#corruptedPackagesDiv').height(); //
+ var var3 = $('# + table.getMarkupId() + ').outerHeight();
//
+ if((var1 + var2) == var3){ //
+ generateCallbackScript(wicketAjaxGet(' + getCallbackUrl() +
') //
+ }});;
and in HTML:
wicket:head
/wicket:head
but nothing changed for IE.

Re: IE call wicket twice from JS
i would google around for other people trying to do this with JS,
doesnt seem like a wicket problem.

IE call wicket twice from JS
Hi All,
I have a table and JS on the page - when table scrolling in the very down
JS function call wicket and label which displayed on the page incremented.
All good with FireFox and all good in case with IE if you will pull
scrolling down by your mouse. But if you will use your mouse wheel - wicket
will be called twice and label will be incremented twice too.
Java:
public class ScrollTableTestPage extends WebPage
{
private int count = 0;
public ScrollTableTestPage()
{
final DataTableContact table = new DataTableContact(table, //
(IColumnContact[]) Arrays.asList(new
PropertyColumnContact(Model.of(Name), name)).toArray(), //
new ListDataProviderContact(generateContacts()),
Integer.MAX_VALUE);
add(table.setOutputMarkupId(true));
final Label label = new Label(label, new ModelInteger()
{
@Override
public Integer getObject()
{
return count;
}
});
add(label.setOutputMarkupId(true));
add(new AbstractDefaultAjaxBehavior()
{
@Override
protected void respond(final AjaxRequestTarget target)
{
count++;
target.addComponent(label);
}
@Override
public void renderHead(IHeaderResponse response)
{
super.renderHead(response);
response.renderOnDomReadyJavascript(getCallbackScript().toString());
}
@Override
protected CharSequence getCallbackScript()
{
String script = var div = document.getElementById('div'); //
+ var table = document.getElementById(' + table.getMarkupId()
+ '); //
+ div.onscroll = function(){ //
+ var var1 = div.scrollTop; //
+ var var2 = div.clientHeight; //
+ var var3 = table.clientHeight; //
+ if((var1 + var2) == var3){ //
+ generateCallbackScript(wicketAjaxGet(' + getCallbackUrl() +
') //
+ } //
+ };;
return script;
}
});
}
private ListContact generateContacts()
{
ListContact contacts = new ArrayListContact();
for (int i = 0; i 30; i++)
{
contacts.add(new Contact(name- + i));
}
return contacts;
}
private class Contact implements Serializable
{
private String name;
public Contact(String name)
{
super();
this.name = name;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
}
}
HTML:
html xmlns=http://www.w3.org/1999/xhtml;
xmlns:wicket=http://wicket.apache.org/;
body
wicket:head
/wicket:head
div class=eXtremeTable id=div
table border=0 cellspacing=0 cellpadding=0 class=tableRegion
width=100% wicket:id=table/table
/div
/body
/html
Sorry, this is not exactly a wicket question but maybe someone can help.

Re: IE call wicket twice from JS
it may be a problem with IE sending events differently. i would try to
use jquery in hopes that it normalizes how events work across
browsers.
