TypeError: $(...).getValue is not a function

Question

我有这个羊驼造型
我想获取表单的内容（用户输入的值）
所以我 found an example 在羊驼网站
当按钮位于 this.getValue(); 内时，该示例工作正常；工作正常
但是从外面我得到 TypeError: $(...).getValue is not a function
我做错了什么？

$("#field1").alpaca({
    "data": {
        "firstName": "John",
        "lastName": "McClane"
    },
    "schema": {
        "type": "object",
        "properties": {
            "firstName": {
                "type": "string",
                "title": "First Name"
            },
            "lastName": {
                "type": "string",
                "title": "Last Name"
            }
        }
    },
    "options": {
        "form": {
            "buttons": {
                "submit": {
                    "title": "Serialize - working fine....",
                    "click": function() {
                        var value = this.getValue();
                        alert(JSON.stringify(value, null, "  "));
                    }
                }
            }
        }
    }
});

<div id="field1" ></div>
<button onclick="console.log(JSON.stringify($('#field1').getValue(), null, '  '))">Serialize - Not working ....</button>

Answer 1

您应该在 $('#field1') 和 getValue() 之间添加 alpaca()

JSON.stringify($('#field1').alpaca().getValue()

这是一个 fiddle。
