QML ListView由Javascript填充 [英] QML ListView filled by Javascript

问题描述

我刚刚意识到（根据一些QML Bugreport），ListView的JSON代理缺失了。所以我有两个选择，用Javascript或C ++创建的模型来填充

I just realized that (according to some QML Bugreport) there is JSON Delegate for ListView missing. So I have two choices, fill it up by model created in Javascript or C++

特别需要从预定义的URL下载.json数据并将它们解析为ListView。

Specially I need to download .json data from predefined URL and parse them to ListView.

我试图在Javascript中创建对象数组并将关联数组推送到ListView作为模型，但它失败了。无论我如何修改代码。

I tried to create object array in Javascript and push assoc array to ListView as Model, but it failed. No matter how i modified the code.

那么只有C ++解决方案或我可以通过Javascript制作ListView模型吗？

So is there only C++ solution or I can make ListView model by Javascript?

谢谢

我试过的代码：

return [{"name":"value"}]
return {"name":"value"}
return [["name","value"]]

问题始终是： ReferenceError：找不到变量：name

推荐答案

根据[e-mail]#qt的建议，请执行以下操作：

Due to advice from [e-mail]#qt do this:

file：gui.qml

file: gui.qml

import "script.js" as Script

model: ListModel { id: list_model_id }

file：script.js

file: script.js

function makeList(id){
    id.append({"name":"value1"});
    id.append({"name":"value2"});
}

致电：

Script.makeList(list_model_id)
