var genAddrId = genAddrId || undefined;
clearInterval(genAddrId);
var btnAddr = document.getElementById("generate-address-btn");

function genNewAddr()
{
    if (btnAddr.innerText[2] != "D") return;

    btnAddr.click();
    setTimeout(function() { btnAddr.click(); }, 1000);
}

function stop()
{
    console.log("\n\n\nOK, will now stop after this final attach has been completed!\n\n\n");
    clearInterval(genAddrId);
}

function start()
{
    console.log("\n\n\nStarting automatic address generation\n\n\n");
    btnAddr.click();
    setTimeout(function() { btnAddr.click(); }, 1000);    
    genAddrId = setInterval(genNewAddr, 5000);
}
