I want a new window will open when i click on the tagcloud links. Can anyone please help me about this topics ???

回答1:

JavaScript solution:

One possible approach could be JavaScript:

<p:tagCloud model="#{tagCloudBean.model}" onclick="preventDefault(event)">
    <p:ajax event="select" update="msg" listener="#{tagCloudBean.onSelect}" />
</p:tagCloud>

onclick triggers a JavaScript function which prevents the link from getting opened.

function preventDefault(e) {
   e.preventDefault();
}

Also, by adding an ajax event you can call a listener in your managed bean.

public void onSelect(SelectEvent event) {
    TagCloudItem item = (TagCloudItem) event.getObject();
    String url = item.getUrl();
    String script = "window.open('" + url + "');"
    RequestContext.getCurrentInstance().execute(script);
}

There you can access the url of the TagCloudItem and execute a JavaScript statement which should open a new browser window.

This possible solution is untested, but just give it a try.
