Answer 1

Check this regexp.

/.+_(\d+)_(.+)/.exec('c_10_249');

result will be

["c_10_249", "10", "249"]

And then only one callback for each elements having ‘mieszkanie’ class.

$(".mieszkanie").click(function() {
    var nums =  /._(\d+)_(.+)/.exec( this.id );
        var num2 = nums[2].substr(0, 3);
    $('.pdf').attr({ 
        href: "img/rzuty/mieszkania/pietro"+nums[1]+"rzuty/" + num2 + ".pdf"
    });
    $('.karta img').attr({ 
        src: "img/rzuty/mieszkania/pietro"+nums[1]+"rzuty/" + num2 + ".png",
        alt: "mieszkanie " + num2
    });
});
