Re: How to implement hint text in a TextField?

[Igor Vaynberg]

i havent had to do this but something like this might work:

class hint extends abstractbehavior {
  private final imodel<string> hint;

  onbind(component c) {
    c.setoutputmarkupid(true);
  }

  ondetach() { hint.detach(); super.ondetach(); }

  renderhead(response) {
   // init textfield with hint
    response.renderondomreadyscript("var
e=document.getelementbyid('"+getcomponent.getmarkupid()+"'");
e.value='"+hint.getobject()+"';e.style['color']='gray';");
  }

  oncomponenttag(tag) {
     tag.put("onfocus", "if (this.value='"+hint.getobject()+"') {
this.value=''; this.style['color']='black;'}");
  }
}

then just textfield.add(new hint(new model<string>("search")));
