No true:)
Why cant you use ID's?
IT is true that forexample dropdown options are created on a specific pattern
but it's somewhat easy to create some javascript which adapts that pattern. We
use a lot of onchange some which are added in the html at some which are added
with the attribute appender (I have a nice litte progressbar component, which
need some html appended and a small javascript appended on the onclick).
Code snips:
<select class="dualdropdown" id="smltype" wicket:id="smltype"
onchange="javascript:smltype_changed()">
<a title="Vis hjælp"
href="javascript:showHelp(766)" wicket:id="top-help">Hjælp</a>
<input id="wordbutton" disabled="disabled"
type="submit" value="Generer rapport" wicket:id="wordbutton"
onclick="showContent('uglyfix');showContent('uniquename');" />
Small code snip on howto workaround the path generated by wicket:
function isAnySelected(formId, name) {
var form = resolve(formId);
var notfound = true;
for (var i = 0; i < form.length; i++) {
var ename = form.elements[i].name;
var prefix = ename.substring(0, ename.indexOf(":"));
if (prefix == name) {
if (form.elements[i].selectedIndex != 0) {
return true;
}
notfound = false;
}
}
return notfound;
}
These are all wicket components, which works nicely...I have more If wanted..

Subject: [Wicket-user] javascript handlers in html - quotes escaping
After 2 months working with Wicket I'm still quite impressed by this
smart framework, but IMHO the most weak part of it is client-side
scripting. So when you want to place a lot of javascript in html, using
handlers like onclick, onkeyup etc, without using server at all (no
ajax, no server callbacks) - it is too difficult (almost impossible).
There are 2 big problems:
1. You can't use id attributes in scripts because wicket generates them.
There is no way to get ID in javascript runtime.
2. Wicket escapes qoutes in javascript handlers in incorrect way. For
example, it transforms the following handler:
onclick="test('test me')"
to the form:
onclick="test(\"test me\")"
And browser (firefox, IE) doesn't understand it, giving "incorrect
character" error.
So now I have to have a lot of java code like the following. And it
would be MUCH better to define it in html.
colorBox.add(new AttributeAppender("onclick", new
AbstractReadOnlyModel() {
@Override
public Object getObject(Component component) {
return "document.getElementById('" +
textField.getMarkupId() + "').value='" + color + "'; " +
"document.getElementById('" +
ColorPicker.this.getMarkupId() + "').style.display='none'; " +
"document.getElementById('" +
colorPreview.getMarkupId() + "').style.background='#" + color + "';";
}
}, ";"));
Is there any way to workaround this problems? Maybe something will be
changed in wicket v2.0?
