Custom Tags
com.webfirmframework.wffweb.tag.htmlwff.CustomTag
class can be used to create a new tag similar to the existing
tags like
Div
.
public class NewTag extends CustomTag {
private static final long serialVersionUID = 1L;
public NewTag(AbstractHtml base, AbstractAttribute... attributes) {
super("newtag", TagType.OPENING_CLOSING, base, attributes);
}
// TODO your own feature methods
@Override
public NewTag clone() throws CloneNotSupportedException {
return (NewTag) super.clone();
}
}
NewTag
may be used as a tag like Div
tag. The below code shows custom tag without keeping a separate class
CustomTag customTag = new CustomTag("newtag", null, new Id("ct1Id")) {
CustomTag customTag = new CustomTag("anothertag", this);
};
System.out.println(customTag.toHtmlString());
this code will print
<newtag id="ct1Id">
<anothertag></anothertag>
</newtag>
The first argument in
CustomTag
constructor is tag name. There are three types of
TagType
,
TagType.OPENING_CLOSING
,
TagType.SELF_CLOSING
and
TagType.NON_CLOSING
. Example for
TagType.OPENING_CLOSING
is <div></div> which has opening and closing tag. Example for
TagType.SELF_CLOSING
is <input type="text"/> which can be self closed and no need to have a
closing tag. Example for
TagType.NON_CLOSING
is <meta charset="UTF-8"> which need neither be self closed nor be closed with
closing tag.
