Network library in javascript mode

Is there any library for the javascript mode ?
I have a sktech who work fine in java mode but not in javascript mode.
here is the sketch

import processing.net.*;
Client myClient;
void setup()
{
   myClient = new Client(this, "192.168.1.10, 8080);   // there is a server a this adress and this port
}

void draw ()
{

//  some drawing a other code
}

void mousePressed ()
{
           myClient.write( "hello \n");
}


As said above this code work fine both in Java mode and Android mode but not in the javascript mode.
In Javascript mode if the line "  import processing.net.*;   " is omitted all work fine except co.
if i add the line import processing.net.*;
i have à blank page.
