How to get a Object from inputs in vanilla javascript

Question

For exemple, i have 3 inputs

Answer 1

You should use a JavaScript object with dynamic property names:

var obj = {};
document.querySelectorAll("input").forEach(input => obj[input.name] = input.value);
console.log(obj);

<input type="text" name="color" value="blue" />
<input type="text" name="flavor" value="acid" />
<input type="text" name="name" value="jack" />

Answer 2

You can loop through the values using a forEach and update the object.
Note: Could also use reduce to directly create the object

const obj = {};
const inputs = document.querySelectorAll("input");
inputs.forEach(({ name, value }) => {
 obj[name] = value
})

console.log(obj);

<input type="text" name="color" value="blue" />
<input type="text" name="flavor" value="acid" />
<input type="text" name="name" value="jack" />

Answer 3

Use JavaScript object instead of an array. To create a object key you just have to declare it between the brackets [ ] and assign a value.

var obj = {};
var x = document.querySelectorAll('input');
for (var i = 0; i < x.length; i++) {
  obj[x[i].name] = x[i].value
}
console.log(obj);

<input type="text" name="color" value="blue"/>
<input type="text" name="flavor" value="acid"/>
<input type="text" name="name" value="jack"/>
