javascript - how to map many arrays values that have same construct to an object? -


how map nested array's values object template, has same construct? had tried ways, still can't goal, can me favor? original data, got backend!

const test_array = [      {          "name": "anymanagedfundsrow",          "columnmeta": {              "a0": "string",              "a1": "string",              "a2": "string",              "a3": "date",              "a4": "date",              "a5": "double",              "a6": "int"          },          "rows": [              [                  "华夏基金管理有限公司",                  "华夏大中华企业精选灵活配置混合(qdii)",                  "其他型基金",                  "2016-01-20",                  "",                  21.877086009428236,                  65135              ],              [                  "华夏基金管理有限公司",                  "华夏大盘精选混合",                  "混合型基金",                  "2015-09-01",                  "2017-05-02",                  10.307680340705128,                  2944              ]          ]      }  ];

target data looks below construct!

let target_data = [      {          "a0": {              "description": "华夏基金管理有限公司",,              "type": "string"          },          "a1": {              "description": "华夏大中华企业精选灵活配置混合(qdii)",              "type": "string"          },          "a2": {              "description": "其他型基金",              "type": "string"          },          "a3": {              "description": "2016-01-20",              "type": "date"          },          "a4": {              "description": "",              "type": "date"          },          "a5": {              "description": "21.877086009428236",              "type": "double"          },          "a6": {              "description": "65135",              "type": "int"          }      },      {          "a0": {              "description": "华夏基金管理有限公司",,              "type": "string"          },          "a1": {              "description": "华夏大盘精选混合",              "type": "string"          },          "a2": {              "description": "混合型基金",              "type": "string"          },          "a3": {              "description": "2015-09-01",              "type": "date"          },          "a4": {              "description": "2017-05-02",              "type": "date"          },          "a5": {              "description": "10.307680340705128",              "type": "double"          },          "a6": {              "description": "2944",              "type": "int"          }      }  ];

just partly ok. how can using index iterate object?

c_obj[index] = value;

const test_array = [      {          "name": "anymanagedfundsrow",          "columnmeta": {              "a0": "string",              "a1": "string",              "a2": "string",              "a3": "date",              "a4": "date",              "a5": "double",              "a6": "int"          },          "rows": [              [                  "华夏基金管理有限公司",                  "华夏大中华企业精选灵活配置混合(qdii)",                  "其他型基金",                  "2016-01-20",                  "",                  21.877086009428236,                  65135              ],              [                  "华夏基金管理有限公司",                  "华夏大盘精选混合",                  "混合型基金",                  "2015-09-01",                  "2017-05-02",                  10.307680340705128,                  2944              ]          ]      }  ];    const tabs_obj = {};    const tabs = test_array.map(      // tab      (tab, index) => {          let p_obj = {},              c_obj = {};          p_obj[tab.name] = [];          // object keys length          let key_length = object.keys(tab.columnmeta).length;          (let key in tab.columnmeta) {              let obj = {};              if (tab.columnmeta.hasownproperty(key)) {                  obj.type = tab.columnmeta[key];                  obj.description = "";                  c_obj[key.touppercase()] = obj;                  // "a0".touppercase(); === "a0"              }              console.log(`%c tabs${index} & c_obj[key.touppercase] = \n`, "color: #f0f", json.stringify(c_obj, null, 2));              // c_obj = {"a0": ""}          }          let t_obj = {};          for(let arr of tab.rows){              arr.map(                  (value, index) => {                      // c_obj[index] = value;                      t_obj[index] = value;                      for(key in c_obj){                          c_obj[key].description = value;                      }                   }              );          }          p_obj[tab.name].push(c_obj);          console.log("%c  \n\n finish c_obj!  = \n\n", "color: red", json.stringify(c_obj, null, 4));          // c_obj = {"a0": "","a1": "","a2": "",a3: "",a4: "", a5: "", a6: ""}          return p_obj;      }  );    // format json : json.stringify(c_obj, null, 4)`

you iterate , map values assigned types.

var test_array = [{ name: "anymanagedfundsrow", columnmeta: { a0: "string", a1: "string", a2: "string", a3: "date", a4: "date", a5: "double", a6: "int" }, rows: [["华夏基金管理有限公司", "华夏大中华企业精选灵活配置混合(qdii)", "其他型基金", "2016-01-20", "", 21.877086009428236, 65135], ["华夏基金管理有限公司", "华夏大盘精选混合", "混合型基金", "2015-09-01", "2017-05-02", 10.307680340705128, 2944]] }],      target_data = test_array[0].rows.map(a =>          a.reduce((r, c, i) =>              object.assign(r, {                  ['a' + i]: { description: c, type: test_array[0].columnmeta['a' + i] }              }), {}));    console.log(target_data);
.as-console-wrapper { max-height: 100% !important; top: 0; }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
