動態項目添加到JavaScript對象

Question

我定義的：

var data ={}; 

我想服用點這樣的對象中的每個「行」：

{field1: "bananas", field2:'test', field3:111, field4:"23.4", field5:"bob"}, 
{field1: "fruit", field2:'test again', field3:222, field4:"30", field5:"john"} 

我知道我能做到這一點，以添加動態和靜態數據：

data['field1']= docType; 
    data['field2'] = docRef; 
    data['field3'] = "test3"; 
    data['field4'] = mydynamicdata; 
    data['field5'] = "test5"; 

但是我怎樣才能添加不同的物品線？此代碼只會添加一個項目集，對吧？我如何添加第二個？

謝謝！

你需要的對象數組 - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array

var data = []; 

data.push({field1: "bananas", field2:'test', field3:111, field4:"23.4", field5:"bob"}) 
data.push({field1: "fruit", field2:'test again', field3:222, field4:"30", field5:"john"}) 

然後你就可以做出這樣的改變：

data[0]['field1'] = 'new value' 
//or: 
data[0].field1 = 'new value' 

哪裏0是名單內的項目的索引。所以將是第二個對象，依此類推......
