Establishment of reference Node js

Kadir

How do you want Node to return the page with a reference to which one can click?

res.send('Документ создан. Вы можете загрузить его здесь - http://localhost:1337/download');

Clickable reference is already HTML. I mean, you're not just gonna have to get your text line back, but something like that:
```
res.send('<html><body>Документ создан. Вы можете загрузить его <a href="http://localhost:1337/download">здесь</a></body></html>');
```

I've found a solution, it's probably not very beautiful, but it works. When we choose something to work a change event, and we can look at the value of what element we've chosen when we get value we find a line with the same class(p-1) as the value(p-1). var categoryOptionArr = []; $('.js-send-category').on('change', function(evt, elem) { if (elem.selected) { categoryOptionArr.push({ name: elem.selected, ind: $(".js-categories-field").find("li."+elem.selected).attr("data-option-array-index") }); categoryOptionArr.filter(function(el) { var nameItem = el.name; var letter = nameItem.charAt(0); if (letter == "p") { $(".search-choice").each(function() { $(this).find(".search-choice-close[data-option-array-index="+el.ind+"]").parent().addClass("trg__color-1"); }); } if (letter == "b") { $(".search-choice").each(function() { $(this).find(".search-choice-close[data-option-array-index="+el.ind+"]").parent().addClass("trg__color-2"); }); } if (letter == "c") { $(".search-choice").each(function() { $(this).find(".search-choice-close[data-option-array-index="+el.ind+"]").parent().addClass("trg__color-3"); }); } }); } });

Simply add a reference to the second input and focus it when the first input is "sended" through the property https://facebook.github.io/react-native/docs/textinput#onsubmitediting . Second input// Adicionar a referencia ao segundo input ref={(input) => { this.input_2 = input; }} First input// Adiciona a função para focar no input_2 quando o // botão de enviar do teclado for pressionado onSubmitEditing={() => { this.input_2.focus(); }} // Definir como falso a propriedade blurOnSubmit para que o campo a seguir continue focado blurOnSubmit={false} Finally a basic example code:<View style={styles.container}> <TextInput placeholder="Primeiro input" returnKeyType = {"next"} onSubmitEditing={() => { this.input_2.focus(); }} blurOnSubmit={false} /> <TextInput ref={(input) => { this.input_2 = input; }} placeholder="Segundo input" /> </View> https://snack.expo.io/@sant0will/d4f9e3

I got the answer, I needed to turn the payload into byte and the key was also wrong, I was using the pagetoken instead of using the secret app... app.post("/:user/gate", async (req, res, next) => { let hmac = crypto.createHmac('sha1', 'APP_SECRET'); console.log(req.rawBody); hmac.update(req.rawBody, 'utf-8'); let computedSig = `sha1=${hmac.digest("hex")}`; console.log(computedSig); console.log(req.headers["x-hub-signature"]); res.send(req.params.user); }); The secret app achieves in the control panel as the print shows: http://prntscr.com/pwexue

All keys are assumed to be numerical:var store = { 0: '0', 1: '1', 2: '2', 3: '3' }; shift(store); console.log(store); /***/ function shift(obj) { var key, prev_key; for (key in obj) { if (!prev_key) { // Первый ключ сохраняется в доп переменную. prev_key = key; continue; } obj[prev_key] = obj[key]; // каждое значение присваивается в предыдущее свойство prev_key = key; } delete obj[key]; // последнее свойство удаляется };

There are, for example, options:To download the right version with https://nodejs.org/download/release/ and launch into consoles node -p process.versions.v8♪To look at the source versions (Git-Hub) in this file: https://github.com/nodejs/node/blob/v13.2.0/deps/v8/include/v8-version.h https://github.com/nodejs/node/blob/v14.13.0/deps/v8/include/v8-version.h We need these lines:#define V8_MAJOR_VERSION 7 #define V8_MINOR_VERSION 9 #define V8_BUILD_NUMBER 317 #define V8_PATCH_LEVEL 23 #define V8_MAJOR_VERSION 8 #define V8_MINOR_VERSION 4 #define V8_BUILD_NUMBER 371 #define V8_PATCH_LEVEL 19 Find the right version in any of these files and see: https://nodejs.org/download/release/index.json https://nodejs.org/download/release/index.tab With regard to souffix -node.MN, it's the number of the nods, you can see them in a line like 'v8_embedder_string': '-node.20', in this file (also on the versions of GitHub): https://github.com/nodejs/node/blob/v13.2.0/common.gypi

It's possible to take the data first. Buffer♪ This requires a call. request with parameter encoding: null♪ The page itself is given as 'text/html; charset=CP1251'respectively and decode You should do it. win1251♪This should work:var req = require("request"); var iconv = require('iconv-lite'); req( { url: "http://sluchajnoe.ru/slovo.php", encoding: null }, function (error, res, body){ var wordRandom = iconv.decode(body, "win1251"); wordRandom = wordRandom.replace(/<font size="200%">(.+)/gi, function(match, p1){ console.log(p1); return p1; }); });

Its "problem" consists of the fact that this request made by the module is Asynchronous i.e.: the request will be made and then you will get an answer, be it the body of the request or an error that occurred on the request.You are declaring a variable without content (response) in the hope of assigning a value to it when the answer comes however, it is accessing (using) this variable before this happens (console.log) ... will always be undefinedYou must use a function callback to work on this value, for example:const request = require("request"); function getWeather(callback) { request(url, function (error, response, body) { callback(body) }) } getWeather(function(responseBody) { console.log(responseBody) }) By default this module does not work with Promise() bad, as described by the module itself you can use adjacent packages if you want to work on "Promises" see the links of adjacent packages: https://www.npmjs.com/package/request#promises--asyncawait If you don't want to use extra packages, know that you can do this natively using the native module utils and "promising" the request:const util = require('util') const request = require("request"); const requestPromise = util.promisify(request); function getWeather(url) { return requestPromise(url).then(response => { if ( response.statusCode === 200 ) { return response.body } return Promise.reject(response.statusCode) }) } getWeather('https://www.google.com').then(body => { console.log(body) }).catch(e => console.log(e)) As not all possible status codes are an error in the request you should treat them as you really want them, the above example will only return the body of the request if the status equals the 200 and will reject all others.Promise() by nature are "asynchronous" functions but you can use ♪ to work on "synchronous" behavior as long as it is within a function async:const util = require('util') const request = require("request"); const requestPromise = util.promisify(request); async function done() { let response = await requestPromise('https://www.google.com') console.log(response.body) } done() In the example above there are no guarantees that the answer will have a property "body" and you will not be able to do any treatment in the event of error/failure other than that the entire code will "wait" the completion of the order and a server may take a long time to respond.A "best" approach would be to treat possible faults in requesting a block .catch():const util = require('util') const request = require("request"); const requestPromise = util.promisify(request); async function done() { async function getWeather(url) { return requestPromise(url).then(response => { if ( response.statusCode === 200 ) { return response.body } return Promise.reject(response.statusCode) }).catch(err => { return err }) } console.log(await getWeather('https://www.google.com')) } done() reading: https://developer.mozilla.org/pt-BR/docs/Web/JavaScript/Reference/Statements/funcoes_assincronas

The trouble is you're in the method. sayHello Write:this.title = 'Andrey'; return this.title; And then you call him on the page, and every time you work with the input, you work the method. sayHello I don't know what to say.And I'd like you to change your mind to the model:<input type="text" v-model="title"> And then the method. changeTitle No need, v-model Works the same way.
