AlpacaJS：选择 Select 后以编程方式更改 TextField 的值

Question

我是 AlpacaJS 的新手，我疯狂地想弄清楚如何做一些简单的事情，比如用 "Select".

的值动态更改文本字段的内容

代码看起来像

$("#form1").alpaca({
    "data": {
        "name": "Default"
    },
    "schema": {
        "title": "What do you think of Alpaca?",
        "type": "object",
        "properties": {
            "name": {
                "type": "string",
                "title": "Name"
            },
            "flavour":{
                "type": "select",
                "title": "Flavour",
                "enum": ["vanilla", "chocolate", "coffee", "strawberry", "mint"]
            }

        }
    },
    "options": {
        "helper": "Tell us what you think about Alpaca!",
            "flavour": {
                "type": "select",
                "helper": "Select your flavour.",
                "optionLabels": ["Vanilla", "Chocolate", "Coffee", "Strawberry", "Mint"]
            }            
        }
    },
    "postRender": function(control) {
        var flavour = control.childrenByPropertyId["flavour"];
        var name = control.childrenByPropertyId["name"];
        name.subscribe(flavour, function(val) {
            alert("Val = " + val);
            this.schema.data = val;
            this.refresh();
        });

    }    
});

我可以看到调用了 postRenderer 中的函数（因为我可以看到具有相关值的警报）但是（也许我在这个阶段脑死亡）我无法使用该值刷新文本字段。

干杯

我可能是看错了要设置的属性...我改成

后

this.schema.data = val;

它运行良好:)
