Add / Toggle Multiple Conditional Classes using React JS | React JS Tutorial

Web Reference: 我是ADD，我有一个朋友是ADHD，我跟他谈论过我和他有什么分别，以下是我们的发现。 ADD是专注力不足。 为何专注力不足？ 因为我们的脑袋像小鸟胃，只要吃一点点就饱。 可能只看了半页书，我们的脑袋就感到压力，无法再看下去。 我们的脑袋很喜欢空空的状态，有一点点工作或责任，我们会感到 ... 关于ADHD的分型，目前还存在争议，DSM5认为ADHD有三种主要表现，第一种是以注意力缺陷为主要表现，一般将这种类型的称为ADD（这是比较早的一种说法），第二种以多动冲动为主要表现，第三种是混合表现——既有注意力缺陷又有多动冲动症状，一般把这三种统 ... 说说个人经验吧。 首先要睡好，睡不好的ADHD成人要专注是几乎不可能完成的任务。 其次运动非常关键，随便选个什么你感兴趣的运动，然后常常去做，运动后的感觉和运动前的感觉简直天壤之别，运动会带给我们需要的刺激和自信。你试一试便知，投入进去，你会知道我说的不假。 然后养成一些 ...

YouTube Excerpt: Let's say we have an element like a button in react JS. How can we use multiple classes for this button while toggling additional classes for it? How to manage and handle multiple conditional classes for an element in React JS? Let's apply multiple classes on this button from everywhere. It will receive two different classes from parent component using props. We will get these props in button component and apply these on button. One way to add multiple classes in ReactJS is to join these classes by using array join method. But this is not developer friendly. We can use template literal to add multiple classes in react js. We can use space, add a static class, add variable class using this. We can add conditional in template literal in react js. So if i click at button, it is changing state. If state is true, we are applying active class as well. Now we have one static class, two classes from parent component and one conditional class from this component. And this is all working. But we can apply an even better way to manage multiple classes on an element in react js. There is a package to handle multiple classes in react js. That is classnames. use npm i classnames to install the package. After installation, import classnames package, declare a variable, use the package to list classes in it. List static class and props in it. And now just use this one variable in class that is holding classnames object containing classes. Add conditional classes in this by declaring an object inside it as parameter. This package can take, static text, variables, conditions, conditional classes and more. Classes can come from anywhere and can be static or result of something or from state, we can manage those all easily by using these methods. ✅ Display Data From JSON File in React https://youtu.be/4fCr1IepJRw ✅ Display Icons / Images from JSON File in React JS https://youtu.be/NWG1Ygt1k1k ✅ Fetch All Types of Data from JSON File in React JS https://youtu.be/8nkVXiGH-7I ✅ 7 Ways to use Images in React JS https://youtu.be/U07wzhfu66M ✅ Easy Way to use Images in React JS https://youtu.be/0EtYzQn-Scw ✅ Require Image Not Working in React JS https://www.youtube.com/watch?v=ay6id01369s ✅ Multiple Images in One Import https://www.youtube.com/watch?v=gEMAZSO85KY ✅ Multiple Sets of Images from One Import in React JS https://www.youtube.com/watch?v=SpjzhwcMcbs ✅ Default Map is not a Function in React JS https://www.youtube.com/watch?v=XMm12Dw_Kpw ✅ Async Await Fetch in React JS https://www.youtube.com/watch?v=9fr7ytpvybY ✅ Assigned a Value but Never Used https://youtu.be/3_4QlPxuEK4 ✅ Easily Sort Before Displaying Records in React JS https://youtu.be/zZzcnmU_LoU ✅ Responsive Image Gallery from Scratch in React JS https://youtu.be/J1dg4WXr3cg ✅ ReactJS Playground https://youtube.com/playlist?list=PL1w28LzkbaQEdqbLVVGuR46lriyR_Ifiy ✅ JavaScript Problem Solving: http://bit.ly/JavsScriptProblemSolving ✅ Web Development Essentials: http://bit.ly/WebDevEssentials ✅ Crash Courses: http://bit.ly/WSPCrashCourses Thank You! 👍 LIKE VIDEO 👊 SUBSCRIBE 🔔 PRESS BELL ICON ✍️ COMMENT Channel: https://www.youtube.com/webstylepress Website: https://www.webstylepress.com FaceBook: https://www.facebook.com/webstylepress Twitter: https://twitter.com/webstylepress GitHub: https://github.com/webstylepress #ReactJS #JavaScript #JS #toggle #react #ClassToggle #EventHandler #programming #WebStylePress #webdevelopment
