How can I display json data on the html using script.js?-CodePudding

index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
</head>
<body>
    <div id="demo"></div>
    <script type="module" src="./js/script.js"></script>
</body>
</html>

script.js:

    import demo from './data.json'
    document.getElementById("demo").innerHTML = demo;
    console.log(demo)

Error in the console:

Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "application/json". Strict MIME type checking is enforced for module scripts per HTML spec.

JSON data locates near script.js in the same directory

How can I display JSON data on the HTML using script.js?

CodePudding user response：

Use JQuery.

<button onclick="showList()">Show List</button>

<script>
  function showList(){
    fetch("./data.json")
      .then(response => response.json())
      .then(data => createList(data));
  }
  
  function createList(data) {
    //code to process here
  }
</script>

You can display JSON data on the HTML using something like this, accessing the data from the imported ./data.json file (If the JSON data is located in the same JavaScript file, you can simply assign the data to a variable and access it from there.) and rendering it, your code is correct but need JSON.stringify(demo) the data.

For example, you can use the document.getElementById() method to select your with id="demo" and then set its innerHTML property to the JSON data.

 const demo = {
"name": "John",
"age": 30,
"city": "New York"
};

const demoDiv = document.getElementById("demo");

demoDiv.innerHTML = JSON.stringify(demo);

This will convert the JSON data to a string and display it
