How to assign a jSON object to a jSON array

Let's say that the jSON object is var kpis, s."A": s.1,2,3,4,5,""b":"2,3,4,5,6', jSON array is var series.

The first method:

[javascript] view plain copy
var index=0;  
for( var tests in kpis){   
     series[index].name=tests;   
     series[index].data=kpis[tests];  
}

Comment: The first method is not applicable in cases where there are more than two name/value pairs, and you can only manually increase the length of the jSON array, which is cumbersome. Guided by boss, there is a second approach.

The second method:

[html] view plain copy
series=[];  
for(var tests in kpis){  
     //定义一个新的jSON对象，改变成jSON数组中jSON数据的格式  
     var json = {name:tests, data:kpis[tests]};  
     //通过数组的push()方法向数组中增加jSON数据  
     series.push(json);  
}

Comment: The second method, when traversing the kpis this jSON object, generates a new format of the jSON object, constantly pushing into the array, so that the purpose is achieved, and even with a name/value pair is not afraid, the versatility is enhanced.

So the second method is recommended.
