It is not possible to find this in JS since the JS code will be implemented after loading.

I'd pardon these functions and use them. Promise.all To wait for everyone to download. About:// Предположим, что fn требует callback последним аргументом function promisify(fn) { return function(...args) { return new Promise((resolve) => fn.bind(this)(...args, resolve)); } } $(function() { $.getScript = promisify($.getScript); $.fn.load = promisify($.fn.load); // Могу ошибаться, но надеюсь, что сработает Promise.all([ // Первая порция $.getScript('js/1.js'), $.getScript('js/2.js'), $.getScript('js/3.js'), $('#header').load('html/header.html'), ]).then(() => Promise.all([ // вторая порция $.getScript('js/dep_1.js'), $.getScript('js/dep_2.js'), ])).then(() => $.getScript('js/another.js')) // Ещё скрипт после второй порции .then(() => { changeLanguage(); console.log('Loaded'); }) }) http://plnkr.co/edit/56U2fBxslEyQRVvK94Hx?p=preview () => {}: https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Functions/Arrow_functions ...args: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/rest_parameters and https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Operators/Spread_syntax https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/Promise https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/Promise/all https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_objects/Function/bind

Ajax works asynchronously, that is, the request is sent and the remainder of the code continues to run.To capture and display the return value of the request, it is necessary to add these functions within callback of success.function getCategoria(id){ $.ajax({ url: "../control/anuncio/index.php", data:{ method: 'get_categoria', id_categoria: id }, method: "post", dataType: "json", success: function(retorno){ exibeMensagem(retorno.categoria); } }); } function exibeMensagem(msg) { alert(msg); } Another way is by adding the option async:false,. Ex:$.ajax({ url: "../control/anuncio/index.php", async: false, data:{ method: 'get_categoria', id_categoria: id }, But there is a problem. Current browsers display the alert:Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/ .The reason? Soon this will be removed and you will not be able to use it. According to the specification of the API...Synchronous requests are in the process of removing the web platform as it has harmful effects for the end user experience.The developers No must pass false to the asynchronous argument when the current global object is a Window. Users are strongly encouraged to warn about such use in development tools and can generate the exception InvalidAccessErrorOf course they will not remove from another to another, but the ideal is to suit as soon as possible. Then the recommended is you create another function to treat the request return (as shown in the first example).

I think you want something like that:import React, { useEffect } from 'react'; import { useHistory } from 'react-router-dom'; import axios from "axios"; import {url} from "../../services/PatientService"; const PatientSidebar = () => { const [patients, setPatients] = useState() const history = useHistory(); useEffect(() => { patients.then((result) => setPatients(result)) // при рендере компонента делаем запрос на сервер, получаем данные и пишем их в стейт }, []) return patients && ( <div className='sidebar'> <div className='search'> <input type="text" placeholder='Search' className='search-form' /> <a href="/patient/new"><button className='new-btn'>New patient</button></a> </div> <div className='list'> <ul> {patients.map((patient) => { // рендерим массив пациентов return ( <li> <div className='patient'> {patient.firstname}{' '}{patient.lastname} </div> <div className='age'> {patient.birth} </div> </li> ) }) } </ul> </div> </div> ); } export default PatientSidebar;

The problem is, you only add the processors without removing the previous ones. Consequently, in some time, the timely processing of a large number of single events begins to cause difficulties for the browser.This problem can be addressed through the use of http://api.jquery.com/on/ and http://api.jquery.com/off/ to add and remove events.

A little physics:The speeds you call normal_speedx and normal_speedy are the projections of the speed vector on X and Y, respectively. "Continuously,Speed is called the speed module, or the length of the vector. The velocity module at known projection using the Pythagoras theorems considered:absoluteSpeed2D = G(speedX2 + speedY2)absoluteSpeed3D = G(speedX2 + speedY2 + speedZ2)On C#, because it's in the mark:double speedX, speedY, speedZ; double absoluteSpeed2D = Math.Sqrt(Math.Pow(speedX, 2) + Math.Pow(speedY, 2)); double absoluteSpeed3D = Math.Sqrt(Math.Pow(speedX, 2) + Math.Pow(speedY, 2) + Math.Pow(speedZ, 2)); Well, it's embarrassing not to know such things.

Yours Content-type header should be: header('Content-Type: application/json'); The header is there so that your app can detect what data has been returned and how it should handle it. In the case would be in application/Json.

In HTML, like in the nucleus, the code goes downstream. I mean, you need to give the tags first. js files) <script src="YOUR_NEED_SCRIPT.js"></script> And then your hat. And of course, don't forget to clean up. async deferso he doesn't get asynchronous.You can also bury your HTML dynamically after loading the necessary violators.//With jQuery //this place you load need scripts, //after add html to document var html = "YOUR_HTML"; $("div.head_container").append(html);

When the coordinates change through JS, there's no point changing them through sss animation. The transition can be challenged by transition. setInterval (function(){ var rand1 = Math.floor(Math.random() * 1000); var rand2 = Math.floor(Math.random() * 1000); var box = document.getElementById('box'); var dot = document.getElementById('dot'); //dot.style.animation = 'flash 1s linear infinite'; if(rand1 >= box.clientWidth){ rand1 = box.clientWidth - 10 } if(rand2 >= box.clientHeight){ rand2 = box.clientHeight - 10 } dot.style.left = rand1 + 'px'; dot.style.top = rand2 + 'px'; },1000) body { padding: 0; margin: 0; } #box { background-color: black; width: 100%; height: 100vh; position:relative; overflow:hidden; } @keyframes anim { 0% {width: 2px; height: 2px; background-color:red;} 10% {width: 3px; height: 3px; background-color:green;} 20% {width: 4px; height: 4px; background-color:blue;} 30% {width: 5px; height: 5px; background-color:yellow;} 40% {width: 6px; height: 6px; background-color:brown;} 50% {width: 7px; height: 7px; background-color:white;} 60% {width: 8px; height: 8px; box-shadow: 1px 1px 3px 1px #998200, -1px -1px 3px #998200;} 70% {width: 8px; height: 8px; box-shadow: 2px 2px 3px 1px #998200, -2px -2px 3px #998200;} 80% {width: 8px; height: 8px; box-shadow: 3px 3px 4px 1px #998200, -3px -3px 4px #998200;} 90% {width: 8px; height: 8px; background-color:green;} 100% {width: 8px; height: 8px; background-color:red;} } #dot { width: 10px; height: 10px; border-radius: 50%; background-color: #fff; position: absolute; top: 10px; left: 20px; transition:top 1s, left 1s; animation: anim 1s steps(1) infinite; }<div id="box"> <div id="dot"></div> </div>

The problem is generated because your array does not have "regular" indexes to be returned as an array in JSON. You started the array count through 1 and not 0.If you have this array below, this will fail:$arr = [1 => 'zero', 2 => 'dois']; echo json_encode($arr); It will generate{"1":"zero","2":"dois"} This return is equivalent to one Object in Javascript and the same do not possess the value length.The ideal in your case would be to use array_values to "reset the indices", since you want to return an array in JSON.echo json_encode(array_values($arr)); This will return:["zero","dois"] Tips 2You can change your $i For 0. This will generate a regular "array" in PHP.Tip 3You can change$produtos[$i] = array()By:$produtos[] = array()This will add the items of array so that it starts from 0Thus will you be able to access the length.Tip 4If you don't want to return the PHP output, just treat it by Javascript. Use Object.values to transform the values of Object in Array.console.log(Object.values(response).length);
