HTML and button and formenctype properties
If you use the formenctype property when you use the label, its value overrides the enctype property value of the label:
Forms with two submit buttons (with different encoding methods), the first submit button uses the default character encoding to submit form data, and the second submit button does not use character encoding to submit form data:
Name: <input type="text" name="fname" value="Ståle Refsnes"><br>
<button type="submit" >使用编码提交</button>
<button type="submit" formenctype="text/plain">不使用编码提交</button>
</form>
