Default text (placeholder) in InputText component

jquery, jsf, jsf-2, placeholder, primefaces

Solution

Primefaces provides a `placeholder` attribute in its latest versions which you can use for `p:inputText`. Also, there is a `p:watermark` component which creates a JS based solution for legacy browser compatibility. So you don't definitely need to set a default value into the backing bean. Just use one of the following solutions:

<h:outputLabel value="Search: "/>  
<p:inputText id="search_input_id" value="#{watermarkBean.keyword}" 
    required="true" label="Keyword" placeholder="search" />

For legacy browsers:

<h:outputLabel value="Search: "/>  
<p:inputText id="search_input_id" value="#{watermarkBean.keyword}" 
    required="true" label="Keyword" />  
<p:watermark for="search_input_id" value="search" />

Also if using JSF 2.2, you can use its passthrough attributes. Adding `xmlns:pt="http://xmlns.jcp.org/jsf/passthrough"` namespace to your page, you can achieve in the following way, both for JSF `h:inputText` and Primefaces `p:inputText`:

<h:inputText value="#{watermarkBean.keyword}"
    pt:placeholder="search" />

Or wrapping it into the tag with a TagHandler:

<h:inputText value="#{watermarkBean.keyword}">
    <f:passThroughAttribute name="placeholder"
        value="search"/>
</h:inputText>

Which creates HTML 5 based input with `placeholder` attribute:

<input placeholder="search">

Problem

I want to display a default Informative text in JSF/Primefaces inputText component. - This text should disappear when user clicks on Text field. - Appear when he clicks outside without typing anything. - If user submits the form without any value, this default value should not be set to Bean's Property. I'm aware that setting the default value to BeanProperty in ManagedBean will work,but I don't want that. Please suggest any JQuery tweaks,If possible. Redirect me to right Question if this question is Duplicate.
