Question

当我单击下一步按钮时，我想在向导中验证varios步骤，而不验证所有输入。单击下一个按钮时，应触发该功能以验证第一步的输入字段。然后在下一步中输入第二步的输入字段，依此类推。下一个按钮是没有提交按钮。

使用VeeValidate的内置作用域非常容易，您可以在以下页面上进行了解：enter link description here

一个简单的解释是通过在字段上添加每个标签/步骤的特定范围：

data-vv-scope="step1"

然后在按下按钮进行验证时使用此方法：

methods: {
    validateForm(scope) {
        this.$validator.validateAll('step1').then((result) => {
            if (result) {
                alert('Form Submitted!');
            }
        });
    }
}

使用vee-validate验证特定数量的输入字段
