Hello! )) I try to write handler for buttons in JS through CSS-selectors. But i meet with difficulties. in case of links this code JQuery works fine:

$(document).ready(function() { // waiting for page loading
var steps = $("form").children(".step"); // find all steps of the form
$(steps[0]).show(); // show 1st step
var current_step = 0; // set the current step
$("a.next").click(function(){ // Event of link-click "necxt step"
if (current_step == steps.length-2) { // checking - will it the next step is last
$(this).hide(); // i hide the link "next step"
$("form input[type=submit]").show(); // show thge button "OK"
}
$("a.back").show(); // show the link "Back"
current_step++; // increase the counter of the current slide
changeStep(current_step); // change a step
});

$("a.back").click(function(){ // Click event on a small window

if (current_step == 1) { // checking - will it the next step is last
$(this).hide(); // hide the link "back"
}

$("form input[type=submit]").hide(); // hide the button "OK"

$("a.next").show(); //hide the link "Next step"

current_step--; // increase the counter of the current slide

changeStep(current_step);// change a step

});

function changeStep(i) { // the function of step changing

$(steps).hide(); // hide all steps

$(steps[i]).show(); // show the current

}

});

But i'd rather to prefer make this fuctionality for buttons - "Next" and "Back" My HTML-code

Hello! I have seen example of a code that was written with using python 3.-- but i work with 2.7 and i don't know how to fix a problem with coding symbols from extensional latin. I suppose that there is little error with syntax. But ok will use Python 3. In this code - example i work with a NTFS-file, which allow you add some additional information for effective using. Here it use for translating some word in different languages. When i input a desire word which i want to translate i get a error: UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 0: ordinal not in range(128). I write some comments to my lines. When the block "Write streams" begins to work - is print only first 2 streams even i input any word which include usuallatin simbols, for example: "White". But, if i work in python 3 - it code works but i get following error. I parse my list named DATA to the list WORDS and i'd to write this content in a streams in 3 languages, but if i use this:

with open(filestream, mode='w', encoding='utf8') as stream:
stream.write(stream_content(dataitem))

i get incorrect content after reading. It looks like as:

T:
r
R:
o

Also i have a mistake, when i try return Word from function find_language. As i know if i put Word in some list and try to return it as list[0], because Word it is single right value, which i try to get through the loop for it in range(len(Result)):
