There's a code. He's checking everything. div-ы c class="number" and renumbers them. But he replaces the whole text. div The numbering number. How to leave the text in the divine so the numbering would be before the text, like: 1. Какой то текст ?
```
jQuery('.number').html(function(i){ return i+1 });
```

Own. https://api.jquery.com/html/ works in such a way as to either return or modify the html contents of the selected elements. In your case, you replace the content inside. div Class number to number number number.
Use the number you need before the content. https://api.jquery.com/prepend/ which will add content inside the selected elements before the existing content.

You can call the function using {}It would be like this:class MinhaClasse { var foo = 'ola mundo'; var bar = 'teste para o stack'; public function index($fn = 'a') { $result = $this->{$fn}(); // <-- é isso que eu quero } private function a() { return $this->foo; } private function b() { return $this->bar; } }

The solution found and the most optimised is the following:<script> $(".btn-plegable").hover(function () { $(this).find(".submenu-gestor").stop(true, true).slideDown("slow"); }, function(){ $(this).find(".submenu-gestor").stop(true, true).slideUp("slow"); }); </script> I needed to point to the div about which I was with (this) and use find to locate the son and make the animation chord style.It is also made of stop() to avoid forming queues; all within the same lines of the previous one.

I think this case is quick to write with SQL.class Phrase < ActiveRecord::Base has_many :translatabilities has_many :translations, through: :translatabilities, class_name: 'Phrase' has_many :voices 特定のPhraseのTranslationが存在し、そのVoiceが一つもない要素を取得したい scope :with_translation_without_voice, -> { query = <<-SQL EXISTS ( SELECT * FROM translatabilities ta INNER JOIN phrases t ON t.id = ta.translation_id WHERE ta.phrase_id = phrases.id AND NOT EXISTS ( SELECT * FROM voices v WHERE v.phrase_id = t.id ) ) SQL where(query) } end The following is the test code:require 'test_helper' class PhraseTest < ActiveSupport::TestCase test '特定のPhraseのTranslationが存在し、そのVoiceが一つもない要素を取得したい' do translation_with_voice = Phrase.create! name: '翻訳、Voiceあり' translation_with_voice.voices.create! name: '音声１' translation_without_voice = Phrase.create! name: '翻訳、Voiceなし' phrase_with_translation_and_voice = Phrase.create! name: 'フレーズ、音声付きの翻訳あり' Translatability.create! phrase: phrase_with_translation_and_voice, translation: translation_with_voice phrase_with_translation_without_voice = Phrase.create! name: 'フレーズ、音声なしの翻訳あり' Translatability.create! phrase: phrase_with_translation_without_voice, translation: translation_without_voice phrase_without_translation = Phrase.create! name: 'フレーズ、翻訳なし' phrases_by_ruby = Phrase.all.select {|phrase| phrase.translations.present? && phrase.translations.all?{|t| t.voices.empty? } } assert_equal [phrase_with_translation_without_voice].map(&:name), phrases_by_ruby.map(&:name) phrases_by_scope = Phrase.with_translation_without_voice assert_equal [phrase_with_translation_without_voice].map(&:name), phrases_by_scope.map(&:name) end end schema.rbActiveRecord::Schema.define(version: 20160104001330) do create_table "phrases", force: :cascade do |t| t.string "name" t.datetime "created_at", null: false t.datetime "updated_at", null: false end create_table "translatabilities", force: :cascade do |t| t.integer "phrase_id" t.integer "translation_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false end add_index "translatabilities", ["phrase_id"], name: "index_translatabilities_on_phrase_id" add_index "translatabilities", ["translation_id"], name: "index_translatabilities_on_translation_id" create_table "voices", force: :cascade do |t| t.string "name" t.integer "phrase_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false end add_index "voices", ["phrase_id"], name: "index_voices_on_phrase_id" end GitHub https://github.com/JunichiIto/not-exists-sandbox By the way, some people think “I don’t really want to write raw SQL, but I don’t want to use Arel to avoid raw SQL!”Arel code is very hard to read, and it is not working with Rails version up. http://qiita.com/joker1007/items/5c851526e73b3bc0273a ) I've seen several times.

I don't know why you might need this, but you can get a class by name. globals():class A: pass def test(cname): # Получаем класс, от которого нужно унаследовать. c = globals().get(cname, None) if c is None: return None # Создаем наследника. class B(c): pass return B x = test('A') print(x, x.bases) Issues such as:$ python test.py <class 'main.test.<locals>.B'> (<class 'main.A'>,)

What you're trying to do is https://en.wikipedia.org/wiki/Reflection_(computer_programming) but there's no reflexia in C+++.There's a possibility for an index to be addressed to a member of the class, but not by his name in the line.Example with index#include <iostream> using namespace std; class A{ public: int member; }; using a_member = int A::*; int main() { a_member m = &A::member; // получаем указатель на член класса //... A* a = new A(); a->member = 42; // обращаемся по указателю cout << (a->*m) << endl; delete a; return 0; } http://ideone.com/dWrMkj On the basis of this, you can create a dictionary (map) of the "name" -- the statue.Minimum implementation:#include <iostream> #include <string> #include <unordered_map> struct A { int first; int second; }; using member_ptr = int A::*; using member_map = std::unordered_map<std::string, member_ptr>; static member_map Amap = { {"first", &A::first}, {"second", &A::second} }; int main() { A a; a.(Amap["first" ]) = 42; a.(Amap["second"]) = 24; std::cout << a.first << std::endl << a.second << std::endl; return 0; } http://ideone.com/JVtKfh

In the particular case of adding one element or another, you can make a loop (loop) with a condition of whether the iterator meets the condition, add one class, otherwise add the other. Example:/** * Actualiza la sección de noticias, al elemento non se le asigna * clase-1 y al elemento par se le asigna clase-2. * */ function cargarNoticias(){ //Inicializar variables var noticias = ''; var limite = 4; // Para efectos del ejemplo seleccionado arbitrariamente. var clase = ''; for (var i = 1; i <= limite; i++){ // Si el iterador es uno o un múltiplo de 4, asigna una clase, en caso contrario la otra clase = (i == 1 || i%4 == 0) ? '"clase-1"' : '"clase-2"'; //Cadena de noticias en formato HTML noticias += '<div class=' + clase + '>\n' + ' <h2>Titulo</h2>\n'+ ' <p>Bajada</p>\n'+ '</div>' } //Actualizar la sección noticias document.getElementById('noticias').innerHTML = noticias; }.clase-1 { color:red }<input type="button" value="Cargar noticias" onclick="cargarNoticias()" > <br/> <div id="noticias">Sin noticias<div>

$(".input_valores_provisionales").keypress(function(event) { var c = event.keyCode || event.which, key = String.fromCharCode(c), chars = "0123456789." return chars.search(key) !== -1 })<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>With the event keypress you can handle it better and with the properties keyCode or which event (depends on the browser) set with function String.fromCharCode.I advise you to join in a string all the allowed characters and check if the entered character is in such a string. Returning false in the method keydown() You block the writing action.

The instance has no "name".What you see is a referencewhich leads you to what is the instance itself. But the name of the reference is only so you can use it to compile your program (instead of, for example, using the value of the stackpointer plus a displacement). For example, the compiled code does not keep the name of local variables, it is completely unknown.To illustrate it, think you do:quesito = lechita; Now the two references point to the same instance. What is the name of this?If you want to identify an instance of a class by an attribute, include that attribute within the class and give it a value. For example:public class ProductoLacteo { //Nota: en singular, porque cada instancia representa un producto private String nombre; public ProductoLacte(String nombre) { this.nombre = nombre; } ... } ProductoLacteo lechita = new ProductoLacteo("Lechita"); Now you can get the "name" by accessing the property (by a getter). You can also reimplement toStringand maybe equals and hashCodein relation to him.

Well, think they're connected to default, all the elements. DOM available document or otherwise.A little snippet, with refined response https://stackoverflow.com/a/153047/3845306 :$(window).click(function() { $('#menucontainer').hide();//Обрабатываем клик ВНЕ меню }); $(document).on('click','.someControl', function(event){ $('#menucontainer').show();//Обрабатываем клик на элементы управления, вызывающие меню event.stopPropagation();//Убираем дальнейшее дефолтное поведение }) $('#menucontainer').click(function(event) { event.stopPropagation();//обрабатываем клик внутри меню });.wrapper{ height: 100%; width: 100%; } #menucontainer{ background: whitesmoke; position: fixed; top: calc(50% - 80px); left:calc(50% - 100px); display: flex; flex-direction: column; padding: 40px; }<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type='button' value='ShowDialog' class='someControl'/> <div class='wrapper'> <div id='menucontainer'> <input type='text' value='SomeTextHere' /> <input type='button' value='Close' onclick='$(this).parent().hide()'/> </div> </div>

You can create a file . POT by Poedit himself to maintain as the main "catalog". The legal one is that by the program itself you can make it search the source code behind the new terms in the source code. From there, you can always update your file . PO from .POT, which it keeps all the translations you have already performed.I believe this is a very efficient way to internationalize any app in PHP.

Good friend, I really don't understand what you mean. How would I just let me select only 1 at a time?I leave you several examples of how to obtain data jqueryNOTE: disabling input[type="checkbox"] because I think you need to only select one. if not the case the user could select the 3 input.$(".con-checks").find("input[type='checkbox']").change(function(){ $(".con-checks").find("input[type='checkbox']").attr("disabled",true) console.log($(this).val()) })<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="con-checks"> <input id="check1" type="checkbox" name="" value="check 1"> <label for="check1">Check 1</label> <input id="check2" type="checkbox" name="" value="check 2"> <label for="check2">Check 2</label> <input id="check3" type="checkbox" name="" value="check 3"> <label for="check3">Check 3</label> <div>$(".con-radios").find("input[type='radio']").change(function(){ console.log($(this).val()) })<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="con-radios"> <input id="radio1" type="radio" name="radios" value="Radio 1"> <label for="radio1">Radio 1</label> <input id="radio2" type="radio" name="radios" value="Radio 2"> <label for="radio2">Radio 2</label> <input id="radio3" type="radio" name="radios" value="Radio 3"> <label for="radio3">Radio 3</label> <div>$(".btns").click(function(){ console.log($(this).text()) })<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button class="btns" type="button" name="button">Boton 1</button> <button class="btns" type="button" name="button">Boton 2</button> <button class="btns" type="button" name="button">Boton 3</button>Let me know if that's what you need or that changes are missing to help you, buddy.
