我有一个带有两个按钮的羊驼毛形式：“保存草稿”和“提交”。我正在尝试为这些按钮实现的行为是：

• 即使没有必填字段或其他验证问题，用户也可以单击“保存草稿”按钮并提交表单；他们的数据将被保存，以便以后可以在表单上继续工作；它们的部分数据返回时将存储在后端，并以data数组的形式包含。
• “提交”按钮的行为正常；在表单验证之前，它将保持禁用状态。他们的最终提交数据将存储在后端，标记为已完成并锁定。

official documentation about validation有点稀疏，似乎暗示可能有必要向表单上的每个字段添加自定义验证器，但是我希望可以有一种更简单的方法；我正在想象“保存草稿”按钮的自定义onClick行为，例如

onClick="function(){$('#form').alpaca('get').justMarkTheWholeFormValidAndGo()}"

我一直在尝试使用基本的“入门”示例表单来完成这项工作：

$("#form").alpaca({
    "data": {
    },"schema": {
        "title": "User Feedback","description": "What do you think about Alpaca?","type": "object","properties": {
            "name": {
                "type": "string","title": "Name","required": true
            },"feedback": {
                "type": "string","title": "Feedback"
            },"ranking": {
                "type": "string","title": "Ranking","enum": ["excellent","ok","so so"],}
    },"options": {
        "form": {
            "attributes": {
                "action": "/path/to/submission/handler/","method": "post"
            },"buttons": {
                "save_draft": {
                    "type": "submit","value": "Save Draft","attributes": {
                        "name": "safe_draft"
                    }
                },"submit": {
                    "type": "submit","value": "Submit","attributes": {
                        "name": "submit"
                    }
                }
            }
        },"helper": "Tell us what you think about Alpaca!","fields": {
            "name": {
                "size": 20,"helper": "Please enter your name."
            },"feedback": {
                "type": "textarea","rows": 5,"cols": 40,"helper": "Please enter your feedback."
            },"ranking": {
                "type": "select","helper": "Select your ranking.","optionLabels": ["Awesome!","It's Ok","Hmm..."]
            },},"hideInitValidationError": true
    }
});
