Question

i’ve a problem… What am I doing wrong?

I want to use a selector previously saved in a variable. The idea is to use it within a function in an object.

var escribir = {
    obj:$('#cont'),
    algo: function(i) { 
        escribir.obj.html(i++);
        setTimeout('escribir.algo('+i+')',1000);
    }
}

$(document).ready(
    function(){
    escribir.algo(0);
    }
);

....
<div id="cont"></div>

You’d probably be better if you made use of closures in better form.

jQuery(function ($) {

    var escribir = {
        obj : $('#cont'),
        algo_counter : 0,
        algo : function () {
            escribir.obj.html(escribir.algo_counter++);
            setTimeout(escribir.algo, 1000);
        }
    };

    // optionally:
    // escribir.algo_counter = 10;

    escribir.algo();

}

This way, you’re not using setTimeout‘s eval version.
