###hijk Javascript WebAPI Development Package

####Getting Started

#####Start Development Service

set PATH to /JAVA 8_HOME/bin
jjs build.js
run.bat

#####Write a Javascript File, demo.js

hijk.api.helloworld = function() {
    return  "Hello World!";
};
hijk.api.helloworld2 = function() {
    return {MSG: 'Hello World!'};
};
hijk.api.helloworld3 = function() {
    return  "<h3>Hello World!</h3>";
};

copy demo.js to ./js/ directory, service will automatically load javascript files when it is changed.
open browser and input http://localhost:8080/api/helloworld
use /edit/js/demo.js that can edit files online,

####Creating HTML to call WebAPI methods, index.html

<html> 
    <script  type="text/javascript">
        function hello() {
            var req = new XMLHttpRequest();
            req.open("GET", "/api/helloworld2", true);
            req.onreadystatechange = function() {
                if (req.readyState === 4 && (req.status === 200)) {
                    var o = eval("(" + req.responseText + ")");
                    alert(o.MSG);
                }
            };
            req.send();
        }
    </script>
    <body>
        <p> <img id="img1" src="" alt="" onclick="hello();"></p>
    </body>
</html>

copy index.html to ./html/ directory
open browser and input http://localhost:8080
click image

####WebAPI Arguments

hijk.api.get = function(map,request) {
    var msg = {
        url: request.getRequestURI(),
        id : map.id[0],
        name: map.name[0] 
    };
    return msg;
};

save
open browser and input http://localhost:8080/api/get?id=99&name=andy

####WebSocket WebAPI

hijk.api.ws_helloname = function(socket, request, response) {

};

####Define Database's Table

    data: {"id": 0, "name": ""},
    key: ["id"],
    index: [["name"]]
}

####Insert Object to Table

hijk.api.table1_insert = function() {
    var tid = hijk.db.id();
    var v = {
        id: tid,
        name: "name" + tid,
        fieldA: "fieldA" + tid,
        fieldB: "fieldB" + tid
    };
    if (hijk.db.insert("table1", v)) {
        return tid;
    } else {
        return -1;
    }
};

####Read Data from Database

hijk.api.table1_select_sum = function() {
    var r = 0;
    hijk.db.select("from table1", [],
            function(v) {
