Javascript Regex to match value of JSON key value pair

问题

Given the following key value pairs, how could I match just the values (including the quotes)?

Explanation: I'm doing a find and replace in my IDE. I have hundreds of key/value pairs where the values need to be changed from strings to objects. So basically replacing the value.

"ElevationFilenameIn": "Input raster elevation file",
"TargetCRS": "Target vertical coordinate reference system Type",
"featureName": "The name of the feature to extract, for example \"Vegetation\" or \"Water\"",
"TargetCRScode": "Target vertical coordinate system Code",
"TargetCRSfile": "The projection (.prj) file in shoebox to be used for this inputfile"

My attempt (which is not working, not even close):

[:]\s*(\"\w*\")

回答1:

You can use the pattern:

[:]\s(\".*\")

and test it following this link: https://regex101.com/r/nE5eV3/1

I guess this one does the job also well. One good part it doesn't use any capture groups one bad part it's more costly compared to the accepted answer.

[^:]+(?=,|$)

回答3:

Get value

[^:"]+(?="})

Get value by key

If you wish to select a specific key that can be done like so:

[^:KEY"]+(?="})
