javascript - Get dynamic request params in node.js -

-

how can construct array says have dynamic dom below?

<input type="hidden" name="file1" value="1.jpg"> <input type="hidden" name="file2" value="2.jpg"> <input type="hidden" name="file3" value="3.jpg"> <input type="hidden" name="file4" value="4.jpg"> .. .. , on

one way save input calculate length of file, req.body.number_of_file later on can loop through that.

is there alternative it?

if inputs consistently , consecutively numbered, in example, go for:

<input type="hidden" name="files" value="4"> <!-- or 5, 6, 42, etc. -->

otherwise, try having inputs part of input array:

<input type="hidden" name="files[]" value="1.jpg"> <input type="hidden" name="files[]" value="2.jpg"> <input type="hidden" name="files[]" value="3.jpg"> <input type="hidden" name="files[]" value="4.jpg">

node.js doesn't support input arrays; here's question tips that: node.js form elements array

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
