elementui el-form 默認不支持回車提交，怎麼解決

概念：

1.在表單的提交按鈕上添加 Vue 原生屬性 native-type="submit" 可以讓按鈕變爲表單提交按鈕；

2.阻止表單默認提交事件（默認是阻止），在表單上（即<el-form>標籤上）添加 @submit.native.prevent 即可

3.因爲el-form默認不支持表單回車提交，在表單上（即<el-form>標籤上）添加@keyup.enter.native="submitForm('form')"可實現回車提交表單

template:

<el-form ref="form" :model="form" :rules="rules" @keyup.enter.native="submitForm('form')">
	<el-form-item label="" prop="username">
	    <el-input prefix-icon="el-icon-user-solid" placeholder="請輸入用戶名" v-model="form.username" clearable></el-input>
	</el-form-item>
	<el-form-item label="" prop="password">
	    <el-input prefix-icon="el-icon-lock" placeholder="請輸入密碼" v-model="form.password" show-password clearable></el-input>
	</el-form-item>
	<el-button class="button" type="primary"  @click="submitForm('form')">登錄</el-button>
</el-form>

script:

methods: {
	submitForm(formName) {
		this.$refs[formName].validate((valid) => {
			if (valid) {
				// console.log(this.form);
				this.$axios.post('login', this.form).then((response) => {
				    console.log(response);
				    this.$message({
					    message: '登陸成功',
					    type: 'success'
				    });
				    localStorage.setItem('token', response.data.access_token); //本地存儲token值
				    // console.log(localStorage.getItem('token'));
				    this.$router.push({
					    path: '/',
				    })
			    }).catch((error) => {
					this.$message({
						message: '賬號或密碼錯誤',
						type: 'error'
					});
				});
			} else {
				console.log('error submit!!');
				return false;
				}
		});
	},
	resetForm(formName) {
		this.$refs[formName].resetFields();
	}
},
created() {
	this.token = localStorage.getItem('token'); //在登錄頁面驗證成功而保存的token值，進行獲取
	    if (this.token) { //若this.token存在
			this.$router.push({path:'/'})
		}
	}
}
