Trying to RegExp an array, getting an Uncaught TypeError: x is not a function-CodePudding

I am trying to get the file names from an array of S3 presigned URLs. The code looks like this:

console.log(plain_filename);

But I get an error saying that Uncaught (in promise) TypeError: input_uri.replace is not a function. Any idea what's wrong with my code? Any advice would help!

CodePudding user response：

input_uri is an array with one string element (because you wrapped it in []s).

.replace is a method available on strings themselves, not arrays.

So you'll need to either get rid of the array braces, or do something like input_uri[0].replace(.. depending on your needs.

CodePudding user response：

Here input_uri is an array, not string and replace is a method available on strings type, not array type.

So you can use input_uri[0].replace(/^.*\/([^/] ?)\?.*$/, '$1');
