The problem probably is in you function. The correct syntax for JavaScript Remoting is found here:

Visualforce.remoting.Manager.invokeAction(
    '{!$RemoteAction.javascriptremoting.loadaccs}',
    function(result, event){
        var names = [];
        if (event.status) {
            for(integer i=0;i<=result.length;i++){
                 names = result[i].Name;
            }
            document.getElementById('ot').innerHTML = names;
        }
    }, 
    {escape: true}
);

Also, make sure that your org has accounts and that the user has access to them.

And, since you're just trying to query some accounts, please consider using Remote Objects
