Answer 1

You could use something like

var button = document.getElementById('button'); // or whatever ID your button has
var textbox = document.getElementById('textbox'); //or whatever ID your input has
button.onclick = function() {
    if (textbox.value === "") {
        return false;
    }
    else {
        return true;
    }
}

Answer 2

You could use this code

jQuery('#<%= button.ClientID %>').click(function(){
    if(jQuery('#<%= textbox.ClientID%>').val()=='')
    {
         return false;
    }
    else
    {
        return(confirm('Are you sure?'));
    }
});
