Hi,
what you miss now are attribute modifiers to change the value of meta
tag attributes. For example if you want to change the content of
attribute 'content' you can use the following label and attribute modifier:
new Label("ogTitle").add(AttributeModifier.replace("content", "Title for
facebook"))
The final markup will be:
<meta property="og:title" content="Title for facebook"
wicket:id="ogTitle" /></meta>
.
I try to use Label with one item but it doesn't change meta tags, but simply
write text on rendered webpage as first line.
html code:
...
<meta property="og:type" content="website static" />
<meta property="og:title" content="title" wicket:id="ogTitle" />
...
java code:
...
public class Facebook extends Panel implements Serializable
{ private static final long serialVersionUID = 1L;
public Facebook(String id, String query, String in)
{
super(id);
add(new Label("ogTitle","Title for facebook"));
}
}
And this is the soucecode of the rendered webpage:
...
<meta property="og:type" content="website static" />
<meta property="og:title" content="title" wicket:id="ogTitle">Title for
facebook</meta>
<meta ...
If I remove content="title" it is almost the same:
...
<meta property="og:type" content="website static" />
<meta property="og:title" wicket:id="ogTitle">Title for facebook</meta>
<meta ...
