单击按钮后，将时间添加到文本区域

Question

When i click id=dodaj_godzine_button i want to add current time to id=formularz_wpis_tresc (as string)

I made this but it's doesn't work.

$("#dodaj_godzine_button").click(function(){
        var data = new Date();
        var godzina = data.getHours();
        var minuty = data.getMinutes();
        var czas = godziny;
        czas += ((minuty < 10) ? ":0" : ":");
        $("#formularz_wpis_tresc").html("Godzina: " + czas + "\n");
    });

Where i've made mistake?

Answer 1

How about this:

$("#dodaj_godzine_button").click(function(){
    var data = new Date();
    var godzina = data.getHours();
    var minuty = data.getMinutes();
    minuty = ((minuty < 10) ? ":0" + minuty : ":" + minuty);
    $("#formularz_wpis_tresc").html("Godzina: " + godzina + minuty + "\n");
});

Answer 2

what's the console log message you got if you take a look at the javascript console? try using

$("#formularz_wpis_tresc").val("Godzina: " + czas + "\n");

see if that works

Answer 3

There where two bugs:

1- czas should be equals to "godzina" instead of "godziny".

2- The right way to show the output is:

$("#formularz_wpis_tresc").html("Godzina: " + czas + minuty + "\n");

Answer 4

Two corrections should make it work:

First, change:

var czas = godziny;

To:

var czas = godzina;

as pointed out by @dfsq in the comments. Then, change:

$("#formularz_wpis_tresc").html("Godzina: " + czas + "\n");

To:

$("#formularz_wpis_tresc").val("Godzina: " + czas + "\n");

as pointed out by @user2325727 , assuming this is the textarea and the clicked element is the the button .
