Hash Table not working in Sahi

balajic

Hi,

I have a Class to have a Hash table as mentioned below in Hash.js. I included this library to my sahi script using _include("Hash.js"). But while calling the methods from the class getting the error in logs like Type Error Function not found in Object.

Tried accessing the code like
var $hash = new HashTable();
$hash.setItems($key,$value); // error at this line of code. Any help will be appreciated.

function HashTable($obj)
{
this.length = 0;
this.items = {};
for (var $p in $obj) {
if ($obj.hasOwnProperty($p)) {
this.items[$p] = obj[$p];
this.length++;
}
}

this.setItem = function ($key,$value) {
_alert("in");
var $previous = "undefined";
if (this.hasItem($key)) {
$previous = this.items[$key];
}
else {
this.length++;
}
this.items[$key] = $value;
return $previous;
};

this.getItem = function($key) {
return this.hasItem($key) ? this.items[$key] : "undefined";
}

this.hasItem = function($key)
{
return this.items.hasOwnProperty($key);
}

this.removeItem = function($key)
{
if (this.hasItem($key)) {
$previous = this.items[$key];
this.length--;
delete this.items[$key];
return $previous;
}
else {
return "undefined";
}
}

this.keys = function()
{
var $keys = [];
for (var $k in this.items) {
if (this.hasItem($k)) {
$keys.push($k);
}
}
return $keys;
}

this.values = function()
{
var $values = [];
for (var $k in this.items) {
if (this.hasItem($k)) {
$values.push(this.items[$k]);
}
}
return $values;
}

this.each = function(fn) {
for (var $k in this.items) {
if (this.hasItem($k)) {
fn($k, this.items[$k]);
}
}
}

this.clear = function()
{
this.items = {}
this.length = 0;
}
}

Instantly the below function worked


var Hash = function(){
this.length = 0;
this.items = new Array();

this.getItem = function(in_key) {
return this.items[in_key];
}

this.setItem = function(in_key, in_value)
{
if (typeof(in_value) != 'undefined') {
if (typeof(this.items[in_key]) == 'undefined') {
this.length++;
}

this.items[in_key] = in_value;
}

return in_value;
}

this.hasItem = function(in_key)
{
return typeof(this.items[in_key]) != 'undefined';
}
}

and the hash can be created by
var $myHash = new Hash();
$myHash.setItem("One",1);
worked perfectly.
