The elementUI input input box monitors the carriage return and causes the page to refresh

Reason: When there is only one el-input input box in the el-form form, pressing Enter in the input box will trigger the submission event of the form.
Solution: Add @submit.native.prevent property to el-form to prevent the carriage return submission event
