Java Script Basics 

[1] Calling a function of another file from your javascript file

file 01:  graphinventor.js
=================

 console.log("-----------------------------------------Time Unit ");
 console.log("Previous Time Stamp ");


var test123 = function (data){
console.log("-----------------------------------------inside test123 ");
console.log(data)
alert("This is an alert" +data);

}

file 02: gadgetconf.js
===============

processData: function(data) {

console.log('data '+JSON.stringify(data));
 // in console of the browser (Ctrl+c) you see the content now as json data

console.log("------------------------");
test123(data);
console.log("------------------------");

}

main.js file (Loading graphinventor.js file first)

       <!-- Custom -->
          <script src="js/graphinventor.js"></script>
          <script src="js/gadgetconf.js"></script>
          <script src="js/main.js"></script>

[2] Callback function is a function passed into another function.

Json  Notes:  

Json Objects:

var me = { "age" : "25", "address" : "Kottawa", "gender" : "male" };

Json Arrays:

var family = [{    "name" : "Dimuthu",    "age" : "25",    "gender" : "male" }, {    "name" : "Nadeesha",    "age" : "25",    "gender" : "male" }];

JsonNeted Objects:

var family = {    "Dimuthu" : {        "sirname" : "Lanerolle",        "age" : "25",        "gender" : "male"    },    "Nadeesha" : {        "sirname" : "Lanerolle",        "age" : "25",        "gender" : "male"    } }

Accessing H2 DB from the browser
----------------------------------------------

1. Navigate to  [Product_Home]/repository/conf/carbon.xml
2. Uncomment below.
 
  <H2DatabaseConfiguration>
        <property name="web" />
        <property name="webPort">8082</property>
        <property name="webAllowOthers" />
        <property name="webSSL" />
        <property name="tcp" />
        <property name="tcpPort">9092</property>
        <property name="tcpAllowOthers" />
        <property name="tcpSSL" />
        <property name="pg" />
        <property name="pgPort">5435</property>
        <property name="pgAllowOthers" />
        <property name="trace" />
        <property name="baseDir">${carbon.home}</property>
    </H2DatabaseConfiguration>

3. Navigate to your primary datasource which points to the H2 datasoure to identify username & password.

eg:

        <datasource>
            <name>WSO2_CARBON_DB</name>
            <description>The datasource used for registry and user manager</description>
            <jndiConfig>
                <name>jdbc/WSO2CarbonDB</name>
            </jndiConfig>
            <definition type="RDBMS">
                <configuration>
                    <url>jdbc:h2:./repository/database/WSO2CARBON_DB;DB_CLOSE_ON_EXIT=FALSE;LOCK_TIMEOUT=60000</url>
                    <username>wso2carbon</username>
                    <password>wso2carbon</password>
                    <driverClassName>org.h2.Driver</driverClassName>
                    <maxActive>50</maxActive>
                    <maxWait>60000</maxWait>
                    <testOnBorrow>true</testOnBorrow>
                    <validationQuery>SELECT 1</validationQuery>
                    <validationInterval>30000</validationInterval>
                    <defaultAutoCommit>false</defaultAutoCommit>
                </configuration>
            </definition>
        </datasource>

4. Type in the browser-url        :      https://localhost:8280
