You are trying to use something that is meant for an object on an array.

您正在尝试使用用于数组上的对象的内容。

values = {};
values['belopp'] = 2322;
values['test'] = 'jkee';

str = JSON.stringify(values);

This is the updated fiddle.

这是更新的小提琴。

You are stringifying an array ([]), not an object ({})Therefore, values = {};

你是字符串化一个array ([])，而不是一个object ({})因此，values = {};
