您可以使用hidden <input>通过表单提交编辑器的内容。将输入放入表单中，设置name，然后每当编辑器的内容更改时使用Javascript更新value。输入的值将随表单自动提交。

<script>
// ... set up quill

// query the input element (use whatever method you prefer)
let inputElement = document.getElementById('hidden-input')
quill.on('text-change', function() {
  // sets the value of the hidden input to
  // the editor content in Delta format
  inputElement.value = JSON.stringify(quill.getContents())

  // you can alternatively use
  // inputElement.value = quill.root.innerHTML
  // if you want the data as HTML
});

</script>

<form>
  <!-- other form stuff -->
  <input type='hidden' name='richText' id='hidden-input'>
</form>

$("#form-perfil").on("submit", function (e) {
