Question

我有大量数据作为每个调用的响应，并以以下格式作为函数的参数进行检索。我需要将所有数据块附加到一个。

function getJSONdata(jsondata){
//Below is where I need help
//cumilatedJSONdata = cumilatedJSONdata + jsondata
}

以下是即将出现的对象的格式：

var jsondata = {"results":[
{"code":"1101696","name":"1101696","price":{"formattedValue":"36.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}}
]};

我希望cumilatedJSONdata结构应类似

var cumilatedJSONdata = {"results":[
{"code":"1101696","name":"1101696","price":{"formattedValue":"36.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}}
]};

我尝试了类似的方法

var cumilatedJSONdata= {"results":[]}

function getJSONdata(jsondata){
var cumilatedJSONdata = $.extend(true,cumilatedJSONdata, jsondata
}
 );

这不会保留以前的数据，而不会被新数据替换。

有人可以帮我吗？

Answer 1

let results = [];

// do your async loop / promise loop here
while (needToGetResults) {
    let newResponse = await asyncRequest();
    results = results.concat(newResponse.results);
}

return results;

或者，

return {results:results}

Answer 2

您可以尝试使用javascript的concat方法

cumilatedJSONdata.results = cumilatedJSONdata.results.concat(jsondata.results);

循环附加对象
