从HTML请求变量到Node JS

Question

I am currently using express to submit my form. In my html, I have a 20 inputs with different ids. The ids for the inputs are address1,address2,address3... I am calling the variables from node js by using req.body.address1. The client has the option of either filling out all 20 inputs or only one or etc. I want to see outputs in my console using node js. Is there any way I can do this without typing console.log(req.body.address) for each variable. Is there a way you can say req.body.address of a count ? Please comment if any confusions occurs

Answer 1

You can use address[] as variable name in HTML. So req.body.address will be array and one console.log will be require.

Or use some js-magic

console.log(Object.keys(req.body).reduce(function(r, k) {if (k.indexOf('address') == 0) r[k] = req.body[k]; return r; }, {}))

Object.keys returns all key from body, then reduce walk by them and put req.body[k] with key k who started from "address" (check by .indexOf('address') == 0 ) to result object.
