Skip to main content

onClick(props.function()) Causes Function Calls repetedly [duplicate]

I am trying to display different things depending if a element is clicked or not in a navbar, in body.main App.js content:

 const [showCatContent, setShowCatContent] = useState(false);

  const toggleCatContent = () => {
    setShowCatContent(!showCatContent);
  };
  console.log(showCatContent)
  return (
    <html><head>
      <meta name="viewport" content="width=device-width, initial-scale=1.0" />
      <script defer src="theme.js"></script>
      <link rel="stylesheet" href="style.css" />
      <link
        href="https://fonts.googleapis.com/css?family=Open+Sans:300,400,700&display=swap"
        rel="stylesheet"
      />
    </head>
    <body>
      <Navbar toggleCatContent={toggleCatContent} />
    <body>
  <Navbar toggleCatContent={toggleCatContent} />
  <main>
   {showCatContent ? (
        <p>This is my cat ahahhahahahaha</p>
      ) : (
        <div>
          <h1>CSS is Cool</h1>

Problem is in referenced navbar, when I try to update showCatInfo state when onClick event is happaning, to do so i call toggleCatContent(), but it causes it to execute it repetedly even if the element is not clicked

const Navbar = (props) => {

return (
  <>
  <nav className="navbar">
    <ul className="navbar-nav">
      <li className="logo" onClick={props.toggleCatContent()}>

I don't exactly understand why, isn't on click supposed to execute when u click on the said element?

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
