javascript - 如何在javascript函数中传递一组json数据？(How to pass a set of json data in javascript function?)

Question

I have a data set as below:(我有一个数据集，如下所示：)

data = '{"a":1,"b":2,"c":3},{"a":4,"b":5,"c":6},{"a":7,"b":8,"c":9}';(数据='{“ a”：1，“ b”：2，“ c”：3}，{“ a”：4，“ b”：5，“ c”：6}，{“ a”：7， “ b”：8，“ c”：9}';) I am trying to make a function with the data set as its parameter, but the parameter wouldn't be read.(我正在尝试使用数据集作为参数来创建函数，但不会读取该参数。) Here is what I did:(这是我所做的：) function add(data) { alert(data);(功能add（data）{alert（data）;) } add(data);(} add（数据）;) I only get [object Object],[object Object] ... What's the problem here?(我只得到[object Object]，[object Object] ...这是什么问题？) Thanks.(谢谢。)   ask by D Kim translate from so

The JSON string is wrong.(JSON字符串错误。)

It should be actually:(实际上应该是：) var data = '[{"a":1,"b":2,"c":3},{"a":4,"b":5,"c":6},{"a":7,"b":8,"c":9}]'; After that, you need to convert the JSON String into JSON object using the code below:(之后，您需要使用以下代码将JSON字符串转换为JSON对象：) JSON.parse(d) /* d is the parameter of the method 'add()' */ The alert will give you [object Object] output, as the variable data is itself the object.(该alert将为您提供[object Object]输出，因为变量data本身就是对象。) So if you want to see the whole json data, you need to console.log as:(因此，如果您想查看整个json数据，则需要console.log为：) console.log(JSON.parse(d)); Watch the demo .(观看演示 。)
