jquery get text from dynamically created input

Question

I have some code that displays the JSON and allows the user to edit the text. After editing, I want to allow the user to click a button to save the new input value. Everything works as expected except for grabbing that new input value.

for (let i = 0; i < jsonObject.results.length; i++) {
    var row = `
    ${jsonObject.results[i].firstName}
    // some code

    $(`#save-${jsonObject.results[i].id}`).click(function(){
      clickAButton(jsonObject.results[i].id, jsonObject, i);
    });

    $(`#fName-${jsonObject.results[i].id}`).on('click', editResult)
    
}

function editResult(){
  var testid = $(this).data('testid')
  var value = $(this).html()

  $(this).unbind()
  $(this).html(``)
}

function clickAButton() {
  var text = $(`#fName-${jsonObject.results[index].id}`).val();
  console.log("text from " + text);
  // code
}

the code above displays

text from

How do I get it to display the new user input?

Instead of writing mutliple event handler for all tds and button you can use only one event handler for button and td . So, when td is clicked just remove data-testid attribute from td so that again that event will not get called and to get input value use $(this).closest('tr').find('.result').val() this will give you input value where save button is clicked.

Demo Code :

var jsonObject = {
  "results": [{
    "id": 1,
    "firstName": "sas"
  }, {
    "id": 2,
    "firstName": "cd"
  }]
}

for (let i = 0; i < jsonObject.results.length; i++) {
  var row = `
    ${jsonObject.results[i].firstName}`

  $("table").append(row)
}

$(document).on('click', 'td[data-testid]', function() {
  var testid = $(this).data('testid')
  var value = $(this).html()
  $(this).html(``)
  //removed data-testid
  $(this).removeAttr("data-testid");
})

$(document).on('click', '[id*=save-]', function() {
  //use class to find input
  var text = $(this).closest('tr').find('.result').val();
  console.log("text from " + text);

})
