How to return callback node.js?
var iwconfig = require("wireless-tools/iwconfig");
let api = {};
api.getStatusWifi = function () {
iwconfig.status(function (err, status) {
console.log(status);
});
// return status ???????????
};
module.exports = api;
如何将“状态回调”return 传递给“getStatusWifi”?
您需要将“api.getStatusWifi =”部分放在状态变量可用的函数中。
var iwconfig = require("wireless-tools/iwconfig");
let api = {};
iwconfig.status(function (err, status) {
api.getStatusWifi = function () {
return status;
};
});
module.exports = api;
var iwconfig = require("wireless-tools/iwconfig");
let api = {};
api.getStatusWifi = function () {
iwconfig.status(function (err, status) {
console.log(status);
});
// return status ???????????
};
module.exports = api;
