动态项目添加到JavaScript对象

Question

我定义的：

var data ={}; 

我想服用点这样的对象中的每个“行”：

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

我知道我能做到这一点，以添加动态和静态数据：

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

但是我怎样才能添加不同的物品线？此代码只会添加一个项目集，对吧？我如何添加第二个？

谢谢！

你需要的对象数组 - 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"}) 

然后你就可以做出这样的改变：

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

哪里0是名单内的项目的索引。所以将是第二个对象，依此类推......
