解析特定值的文本以使用Javascript创建JSON对象

Question

I need to convert text file entries into a JSON object however I am having trouble understanding how to look for certain values. Given the text document sample:

"get rf_da

Device Timestamp, 6/16/2015 2:14:48 PM"

How would I find the value of the date and the string following "get" using Javascript.

Answer 1

One way would be to use a regular expression, for example, the following line would retrieve the date string following the text after the 'get'.

var textFileLine = "get rf_da /n Device Timestamp, 6/16/2015 2:14:48 PM"; var lineAfterGetRegEx = /(get)([\\w|\\s|\\n]+)(Device Timestamp,\\s)([^"]+)/g; var lineAfterGetMatch = lineAfterGetRegEx.exec(textFileLine); alert(lineAfterGetMatch[4]);

From there, you can refine the regular expression above to retrieve the date. Here is a handy online regex tester you can use: https://regex101.com/
