form serialize javascript (no framework)

Question

Wondering is there a function in javascript without jquery or any framework that allows me to serialize the form and access the serialized version?

Answer 1

my way...

const myForm = document.forms['form-name']

myForm.onsubmit=e=>
  {
  e.preventDefault()  // for testing...

  let data = Array.from(new FormData(myForm))
                  .reduce((r,[k,v])=>{r[k]=v;return r},{})

  /*_______________________________________ same code: for beginners 
  let data = {}
  Array.from(new FormData(myForm), (entry) => { data[ entry[0] ] = entry[1]} )
  ________________________________________________________________*/
 
  console.log(data)
  
  //...
  }
