append string to textbox contents?

pretty simple, I have buttons but i want to add their value to a textbox when they are clicked, ho开发者_高级运维w would i go about doing this in jQuery? They are all numbers and their cant be more than 10 in the textbox.

pretty easy task with jQuerys .val()^help method:

$('button').click(function(event) {
    $('input:text').val(function(index, val) {
        return val + event.target.value;
    });
});

or

$('button').click(function() {
    $('textarea')[0].value += $(this).val();
});

use jquery .val to set the text box value , it should do it
