HTML form posting (browser) New

You can also post a form directly from a HTML form element. This is useful when you have a form in your page and you want to submit it without any JavaScript code.

await axios.postForm(
  "https://httpbin.org/post",
  document.querySelector("#htmlForm")
);

FormData and HTMLForm objects can also be posted as JSON by explicitly setting the Content-Type header to application/json:

await axios.post(
  "https://httpbin.org/post",
  document.querySelector("#htmlForm"),
  {
    headers: {
      "Content-Type": "application/json",
    },
  }
);

An example of a form that is valid and can be submitted by the above code is:

<form id="form">
  <input type="text" name="foo" value="1" />
  <input type="text" name="deep.prop" value="2" />
  <input type="text" name="deep prop spaced" value="3" />
  <input type="text" name="baz" value="4" />
  <input type="text" name="baz" value="5" />

  <select name="user.age">
    <option value="value1">Value 1</option>
    <option value="value2" selected>Value 2</option>
    <option value="value3">Value 3</option>
  </select>

  <input type="submit" value="Save" />
</form>

The above form will be submitted as:

{
  "foo": "1",
  "deep": {
    "prop": "2",
    "prop spaced": "3"
  },
  "baz": ["4", "5"],
  "user": {
    "age": "value2"
  }
}
