Image zoom (power zoomer) effect using Jquery in ADF Faces

This post talks about - how to add mouse hover caption to images? Caption means a brief explanation of picture/image. Normally 'alt' attribute of HTML page is used as Image Caption
But in ADF Faces af:image doesn't has 'alt' property , there is a property called 'shortdesc' and this property is used as 'alt' attribute for image when jsf page is loaded at client browser
you can check this in html source of your page in browser (inspect element)

<af:image shortDesc="Black Horse running or flying" id="FirstImage"
                                  inlineStyle="height:300px;width:500px;"
                                  source="#{resource['images:Best-Wild-Animal-Photos-of-2012-307-black-horse-running.jpg']}"/>

JSF page is converted to html for client side presentation, see in HTML source 'shortdesc' is used as 'alt' property

jQuery is used for client side scripting of HTML so jQuery script makes use of this 'alt' attribute to show animated caption for image
There are lots of jQuery and JavaScript available for showing different types of captions , here i am using jQuery Capty - A Caption Plugin (Download jQuery script and respective css file from link)

Now follow steps to use this jQuery plugin with ADF Faces

• Create Fusion Web Application and a page in viewController, added jQuery script and css in viewController project (Jdev 12.1.3)





• Add jQuery library and script file reference to page, also add css file reference to page



 //jQuery library reference
            <af:resource type="javascript" source="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></af:resource>
            //jQuery file reference that will be used to show caption
            <af:resource type="javascript" source="js/jquery.capty.js"/>
            <af:resource type="javascript" source="js/jquery.capty.min.js"/>
            //CSS file to style Caption
            <af:resource type="css" source="css/jquery.capty.css"/>



• Next step is to execute jQuery function on pageload to show caption



//Function to show default sliding caption

$('#ImageId').capty();

//Change default fucntion to change animation type , speed and height of caption

$('#ImageId').capty({
animation: 'fade',
speed:     1000
}) 



• So here i am using both function for two different images (for first image animation type is slide (default) and for second it is fade), add clientListener to document tag and set it's type to 'load' (to execute jQuery function on pageload)



 <af:clientListener method="jQuery(document).ready(function($){ $('#FirstImage').capty(); $('#SecondImage').capty({animation: 'fade',   speed:     1000}) })" type="load"/>



• Run application and see magic of jQuery

Image Caption (animation:slide)-


Image Caption (animation:fade)-



• you can change style (color,font etc) of caption box by modifying css sheet and size can be increased or decreased from jQuery function. for example i have changed color, font and size of caption box. see this



@CHARSET "UTF-8";

div.capty-caption {
 background-color: red;
 color: #FFF;
 font: bold 11px cursive;
 padding-left: 10px;
 padding-top: 7px;
 text-shadow: 1px 1px 0 #222;
}

div.capty-caption a {
 color: #318DAD;
 font: bold 11px verdana;
 text-decoration: none;
 text-shadow: none;
}


jQuery function to increase size-



jQuery(document).ready(function($){ $('#FirstImage').capty(); $('#SecondImage').capty({animation: 'fade',   speed:1000,height:50}) })


See output-

Image zoom (power zoomer) effect using Jquery in ADF Faces

Jquery is most popular javascript library ,it is used to provide better ui design, animations and client side events
This is another post about using jquery in ADF Faces, see previous post
Using JQuery in Oracle ADF

In this post i am using a jquery script to zoom (enlarge) image on hover , you have seen this in many e-commerce websites as they provide power zoom feature to enlarge product image for better customer experience



I have taken this jquery script from Dynamic Drive, see the documentation
To implement this in ADF Application follow these steps

• Create a Fusion Web Application and a page in viewController project (Jdev 12.1.3)





• Downloaded jquery script file from above link -ddpowerzoomer.js, add this jquery file to viewController project





• Now add jquery library reference in page in order to use jquery functions



<af:resource type="javascript" source="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></af:resource>
            <af:resource type="javascript" source="js/ddpowerzoomer.js"/>



• Next step is to add an image to page , so added an af:image to page and set path of image to display





• Now i have to execute jquery function that will add power zoom feature to this image (See jquery code that will be executed on pageload)



jQuery(document).ready(function($){
 $('#i1').addpowerzoom({
  defaultpower: 2,  powerrange: [2,5],  largeimage: null,  magnifiersize: [75,75]  }) 
})


here i1 is the id of image, default zoom power and magnifier size is configured here

• So to execute this jquery function on pageload , added a clientListenr to pagelike this



<af:clientListener type="load"
                               method="jQuery(document).ready(function($){   $('#i1').addpowerzoom({  defaultpower: 2,  powerrange: [2,5],  largeimage: null,  magnifiersize: [75,75]  }) })"/>



• Now run this application and check it, magnifier is on deer :)





• Now i am increasing size and power of magnifier - Power is 3 and size is 200x200

Populate af:table programmatically from managead bean using POJO

This post is about a common question
How can we populate an af:table programmatically ?

It means that data in af:table is not populated through model layer (Using ViewObject) using binding layer. lets say I have some values in our managed bean and have to show records in tabular format on page

So what we have to do -

• First you should know the number and data type of columns in table, suppose i have to populate a table for person details (name, mobile number and salary). to get and set value of columns i have created a java bean class , it has 3 variable for 3 columns





// Java Class to set and get value for table column
public class PersonBean {

    public PersonBean(String name, String moNo, Integer salary) {
        this.Name = name;
        this.mobNo = moNo;
        this.salary = salary;
    }
    private String Name;
    private String mobNo;
    private Integer salary;

    public void setName(String Name) {
        this.Name = Name;
    }

    public String getName() {
        return Name;
    }

    public void setMobNo(String mobNo) {
        this.mobNo = mobNo;
    }

    public String getMobNo() {
        return mobNo;
    }

    public void setSalary(Integer salary) {
        this.salary = salary;
    }

    public Integer getSalary() {
        return salary;
    }
}



• Next step is to create a managed bean for referencing af:table , this managed bean makes use of person java bean class to add data in same format for all table rows. A List data structure is used to pass all values in af:table. See code of managed bean 



//ArrayList to poplate data in af:table
    List<PersonBean> personList = new ArrayList();

    //To Populate default row in table (Code in Constructor)

    public ProgTableBean() {
        personList.add(new PersonBean("Ashish Awasthi", "xxxxxxxxxx", 50000));
    }

    public void setPersonList(List<PersonBean> personList) {
        this.personList = personList;
    }

    public List<PersonBean> getPersonList() {
        return personList;
    }



• Now just drop an af:table on page and set it's properties like value, column header and text values in columns



 As i have to show only 3 columns so deleted extra ones



 Set properties -
 value- from where table collection is populated
 columns values- take the var reference of table and refer variable name in List (here 'row' is table var and second is variable name in person bean class)




 See the XML source of af:table-



<af:table var="row" rowBandingInterval="1" id="t1" value="#{viewScope.ProgTableBean.personList}"
                          partialTriggers="::b1">
                    <af:column sortable="false" headerText="Name" id="c1" width="150">
                        <af:outputText value="#{row.name}" id="ot1"/>
                    </af:column>
                    <af:column sortable="false" headerText="Mobile Number" id="c2">
                        <af:outputText value="#{row.mobNo}" id="ot2"/>
                    </af:column>
                    <af:column sortable="false" headerText="Salary" id="c3" align="right">
                        <af:outputText value="#{row.salary}" id="ot3"/>
                    </af:column>
                </af:table>



• Now run this application and see there will be one row in table as code is added in constructor of managed to populate one row





• I have added a form and button in page to add new records in table , see the form source code



<af:panelFormLayout id="pfl1">
                    <f:facet name="footer"/>
                    <af:inputText label="Name :" id="it1" binding="#{viewScope.ProgTableBean.nameBind}"/>
                    <af:inputText label="Mobile Number :" id="it2" binding="#{viewScope.ProgTableBean.mobNumBind}"/>
                    <af:inputText label="Salary :" id="it3" binding="#{viewScope.ProgTableBean.salaryBind}">
                        <af:convertNumber/>
                    </af:inputText>
                    <af:button text="Add Record" id="b1" actionListener="#{viewScope.ProgTableBean.addNewRcord}"/>
                </af:panelFormLayout> 


Code in managed bean for button action-

    /**Method to add new record in table
     * @param actionEvent
     */
    public void addNewRcord(ActionEvent actionEvent) {
        //Get all values using compoenet binding as mobNumBind
        if (mobNumBind.getValue() != null && nameBind.getValue() != null &&
            salaryBind.getValue() !=
            null) {
            // Add new Record in List
            personList.add(new PersonBean(nameBind.getValue().toString(), mobNumBind.getValue().toString(),
                                          Integer.parseInt(salaryBind.getValue().toString())));
        }
    }



• now run and check application-
