我们可以更改Key的Json数据值吗？

I have retrieved JSON data content of a web page and want to use it in app.

我检索了网页的JSON数据内容，并希望在应用程序中使用它。

One of the key's value contain data with "\n and commented out lines". I want to remove them and use only simple text information.

其中一个键的值包含带有“\ n和注释掉的行”的数据。我想删除它们并仅使用简单的文本信息。

I can't put my code because the "commented line" are not visible here.

我无法放入我的代码，因为这里看不到“注释行”。

Here is a demo:

这是一个演示：

{"content":"Hello \n 'CommentedLinesHere' \n how are you? " }

So, is there any way to get “Hello how are you?” here?

那么，有没有办法让“你好，你好吗？”在这里？

Any help would be appreciated.

任何帮助，将不胜感激。

Use the global flag from regex to globally replace your char and then turn it back into a JSON object

使用regex中的全局标志来全局替换您的char，然后将其转换回JSON对象

var noNewLines = JSON.stringify(myJson);
noNewLines = noNewLines.replace(/\n/g, "");
var backToJson= JSON.parse(noNewLines );

#2

var objJsonData = {"content":"Hello \n 'CommentedLinesHere' \n how are you? "}
    var ResultJson = objJsonData.content.replace(/\n/g, '').replace("CommentedLinesHere",'').replace("'",'').replace("'",'');
    alert(ResultJson);

You need to use a regex to replace all the \n newline characters with a blank space. See the code below:

您需要使用正则表达式将所有\ n换行符替换为空格。请参阅以下代码：

var obj = {"content": "Hello \n 'CommentedLinesHere' \n how are you? "}
var str = obj.content.replace(/\n(.|\n|\r)+\n/g, "");
alert(str);
