如何将值输入到 javascipt 的 object 中？

Question

let inputInf=document.getElementById('inputInf');

let nameStudent=inputInf;

let output= new Student(nameStudent,number);
 
document.getElementById("btn").onclick=(event)=>{
     let xuatTTMH=document.getElementById("outputInfor");
     xuatTTMH.innerHTML=output.nameStudent;    
}

I thought I can do it this way but the answer is [object HTMLInputElement] . Can you please help me to solve this problem or give me the keyword of this situation?

Thanks for your help.

Answer 1

Do you mean the value of nameStudent is [object HTMLInputElement] ? It's because you didn't get the value from the input field. For the first line, it should be:

let inputInf = document.getElementById('inputInf').value;

Answer 2

You are getting a HTMLInputElement object

https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement

There is a 'value' property that you need to check to get the object value from your inputInf var.
