如何从JS中获取JSON的值(How to get the value from JSON in JS)

如何从JS中获取JSON的值(How to get the value from JSON in JS)

我正在尝试从此JSON文件中获取“formatted_address”值。 我是新手，发现文档很混乱。 我现在的代码如下，其中变量“location”是如上所述生成的url。

$.getJSON(location, function( data ){ stad = data.results.formatted_address; console.log(stad); });

我怎么做到这一点？

I'm trying to get the "formatted_address" value from this JSON file. I'm new to this and found the documentation quite confusing. The code I have now is the following where the variable "location" is the url generated like the one above.

$.getJSON(location, function( data ){ stad = data.results.formatted_address; console.log(stad); });

How would I achieve this?

results是一个数组，因此您需要将其作为一个数组进行访问。 鉴于您的示例只有一个项目，您可以通过索引直接访问它：

var stad = data.results[0].formatted_address; // = "'s-Hertogenbosch, Netherlands"

如果数组中有多个项目，则需要循环遍历它们：

for (var i = 0; i < data.results.length; i++) { var stad = data.results[i].formatted_address; // do something with the value for each iteration here... }

results is an array, so you need to access it as one. Given your example with only one item, you can access it directly by index:

var stad = data.results[0].formatted_address; // = "'s-Hertogenbosch, Netherlands"

If there were multiple items in the array you would need to loop through them:

for (var i = 0; i < data.results.length; i++) { var stad = data.results[i].formatted_address; // do something with the value for each iteration here... }
