How do I fix this code regarding getelementbyid [Javascript]?

document.getelementbyid value
javascript getelementbyid value
document.getelementbyid set value
innerhtml
getelementsbyclassname
document.getelementbyid returns null
document.getelementbyid(...) is null
document.getelementbyid is not a function

So I'm currently taking a coding class and am not very well versed in coding. I'm having trouble with a getelementbyid block which isn't writing my looped array for an assignment. Could anyone help me out?

Here's the code:

<html>

<body>
  <h1 align=center>Name and Grades</h1>
  <p id="message"> Name </p>
  <p id="message2"> Grade </p>

  <script>
    var input = []
    var message = " "
    var message2 = " "

    var n = 0
    var i = 1
    var names = n
    var grade = i
    for (n = 0; n < 1; n++) {
      var names = n + 1
      input[n] = window.prompt("Enter First Name" + names)
      message += "Your name is " + input[n] + "<br>"
    }

    for (i = 1; i < 5; i++) {
      input[i] = window.prompt("Enter Grade (numerical value)" + grade)
      message2 += "Grade " + i + " is " + input[i] + "<br>"
    }

    document.getElementById(message).innerHTML = "your name is " + input[n] + "<br>"
    document.getElementById(message2).innerHTML = "Grade" + i + " is " + input[i] + "<br"
  </script>
</body>

Target Color Event JavaScript Purple onmouseover onmouseout document. getElementById​("radioLink").style.display="none"; Blue onmouseover onmouseout document. In IE8 Standards mode, getElementById performs a case-sensitive match on the ID attribute only. In IE7 Standards mode and previous modes, this method performs a case-insensitive match on both the ID and NAME attributes, which might produce unexpected results.


Your variables and your id-s have the same names. By doing getElementbyId(message) you are passing the variables' values instead of the fixed id you gave to your elements.

You need to put the id-s in quotes as follows:

document.getElementById("message")
document.getElementById("message2")

Document.getElementById(), The capitalization of "Id" in the name of this method must be correct for the code to function; getElementByID() is not valid and will not work,  The capitalization of "Id" in the name of this method must be correct for the code to function; getElementByID() is not valid and will not work, however natural it may seem. Unlike some other element-lookup methods such as Document.querySelector() and Document.querySelectorAll() , getElementById() is only available as a method of the global

error:- The id of getElementbyId must be in quotes

Professional JavaScript for Web Developers, getElementById() is the standard way of achieving this, it is tested for first. Testing for the most common solution ensures optimal code execution by avoiding  var owctl7fzk = "the_id"; var element = document.getElementById(owctl7fzk); owctl7fzk is definitely not the same as "owctl7fzk", because the former is a variable name, while the latter is a string. This is how JavaScript works. Just because you can omit the quotes in HTML doesn't mean that you can do the same in JavaScript.

Below should be sufficient for your assignment:

HTML (index.html):

<h1 style="text-align: center">Name and Grades</h1>
<table>
  <thead>
    <th>Name</th>
    <th>Grade</th>
  </thead>
  <tbody id="data">
  </tbody>
</table>
<script src="script.js"></script>

JS (script.js):

let student = []

for (let i = 0; i < 5; i++) {
  student[i] = {
    "name": window.prompt(`Enter Name ${i + 1}`),
    "grade": window.prompt(`Enter Grade (numerical value) ${i + 1}`)
  }
}

document.getElementById('data').innerHTML = student.map(student => {
  return `<tr><td>${student.name}</td><td>${student.grade}</td></tr>`
})
