问题描述
我正在寻找新JsObject.jsify
的反向。东西,将javascript 对象
转换回Dart 地图
是否有可用的东西?
I am looking for some reverse of new JsObject.jsify
. Something, that would convert javascript Object
back to Dart Map
Is there something like that available?
我知道我可以使用JSON转换为字符串,但这并不涉及包含函数,Dart对象,Dom Elements的 Object
的转移等等......有没有更好的方法?
I know that I can use JSON conversion to string, but this does not address transfer of Object
s containing functions, Dart objects, Dom Elements, etc... Is there any better method?
推荐答案
如果你想深入处理并处理其他案例那么简单映射和保留函数(与json解决方案不同)然后使用这个简单的函数:
If you want to do it deeply and handle also other cases then simple maps AND preserve functions (unlike the json solution) then use this simple function:
_toDartSimpleObject(thing) {
if (thing is js.JsArray) {
List res = new List();
js.JsArray a = thing as js.JsArray;
a.forEach((otherthing) {
res.add(_toDartSimpleObject(otherthing));
});
return res;
} else if (thing is js.JsObject) {
Map res = new Map();
js.JsObject o = thing as js.JsObject;
Iterable<String> k = js.context['Object'].callMethod('keys', [o]);
k.forEach((String k) {
res[k] = _toDartSimpleObject(o[k]);
});
return res;
} else {
return thing;
}
}
