Converting Array of Objects into Array of Arrays
提问by KiddoDeveloper
There is a condition where i need to convert Array of objects into Array of Arrays.
有一种情况，我需要将对象数组转换为数组数组。
Example :-
例子 ：-
arrayTest = arrayTest[10 objects inside this array]
single object has multiple properties which I add dynamically so I don't know the property name.
单个对象有多个我动态添加的属性，所以我不知道属性名称。
Now I want to convert this Array of objects into Array of Arrays.
现在我想将此对象数组转换为数组数组。
P.S. If I know the property name of object then I am able to convert it. But i want to do dynamically.
PS如果我知道对象的属性名称，那么我就可以转换它。但我想动态地做。
Example (If I know the property name(firstName and lastName are property name))
示例（如果我知道属性名称（firstName 和 lastName 是属性名称））
var outputData = [];
for(var i = 0; i < inputData.length; i++) {
var input = inputData[i];
outputData.push([input.firstName, input.lastName]);
}

Try this:
试试这个：
var output = input.map(function(obj) {
return Object.keys(obj).sort().map(function(key) {
return obj[key];
});
});

将对象数组转换为数组数组：
var outputData = inputData.map( Object.values );
var outputData = inputData.map( Object.values );

Use the for-inloop
使用for-in循环
var outputData = [];
for (var i in singleObject) {
// i is the property name
outputData.push(singleObject[i]);
}
