In addition to the submit button, there may be some other functional buttons in the form, such as the send captcha button. When using these buttons, be careful to set the native type to button, otherwise the form submission will be triggered.

<van-button native type="button"> </van-button>Copy the code

Summary: The cause of this problem is that the default value of the button tag type attribute in the browser is submit, which triggers the form submission. We will avoid this problem by changing the default value of Type to Button for the next big release.
