XPath(XML Path Language)

XPath(XML Path Language)是一種XML路徑語言,那也能用來當查詢語言
以前玩爬蟲時也蠻常用XPath(XML Path Language),現今瀏覽器也能直接透過原始碼複製XPath路徑
這次示範的網站一樣是RoS-BoT


今天主要想爬如下圖紅框部分

對紅圈內的文字按右鍵檢視原始碼,按右鍵/Copy/Copy XPath

使用Node.js和Redis建立一個HTML5聊天室

這篇程式碼主要由IBM Developerworks所提供
我建置的專案如下圖

這篇想法就是透過WebSocket來建立通訊
將接收到的值以JSON方式存進Redis的list內
並透過Broadcast filter到的訊息將其加入至聊天室內

app.js

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var indexRouter = require('./routes/index');
var app = express();


// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', indexRouter);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};
  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

JavaScript 阻擋Form表單送出動作

Form透過POST/GET方法傳送出資料,如果要檢查欄位輸入是否正確才讓傳送表單資料
可以透過onsubmit事件去攔截,該方法前得加上return

Google Maps API 分析導航功能Sample Code

最近幫忙滅火會用到導航功能,順便寫一下筆記XD

要實現這個功能必須使用Directions Service類別的route方法



route能帶入DirectionsRequest以及一個function
DirectionsRequest這個物件裡面有這些屬性

jQuery 修改z-index達成置頂廣告效果

使用ADB對Android Chrome Debugging

手機上的Chrome沒有像電腦的Chrome版本有開發人員工具可以使用,我找到了『Remote Debugging on Android』作為本篇文章的主要參考來源
除錯前要先到Chrome商店下載『ADB』,某些Chrome版本不支援『ADB』,不支援的狀況下可能要去安裝其他的Chrome版本

首先,下載ADB


安裝後,會在Chrome的右上角看到一個Android寶寶的圖示


點擊Android寶寶的圖示會出現選單,選擇Start ADB

就可以開始使用View Inspection Targets除錯了

開啟除錯畫面大概就是這樣,手機必須用USB線與電腦做連結,並且開啟Debugging功能
連接後,手機端必須開啟Chrome,沒有開啟的話不會有網址列給你輸入網址和不具備除錯功能

HTML5 localStorage 與 sessionStorage

HTML5新增了Web Storage的方法,分別是『localStorage』與『sessionStorage』兩者差異僅在儲存時間長短而已

localStorage:能夠無限期將值儲存在瀏覽器內,除非使用者清除歷史紀錄,否則會一直儲存到瀏覽器的空間之中

sessionStorage:儲存期限僅止於網頁還沒被關閉前都會一直存在,網頁關閉時,會將值刪除

在還沒任何動作之前,我們可以透過瀏覽器的開發工具來查詢目前『localStorage』與『sessionStorage』使用狀況


 按鈕未被觸發時,可以得知『localStorage』與『sessionStorage』尚未被使用

在Bing Maps API加入標記圖示

Bing Maps API也可以標記圖示,有興趣可以參考『Adding Entities to the Map

程式碼如下:

<!DOCTYPE html>
<html>
 <head>
  <meta charset="utf-8">
  <script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script>
  <script type="text/javascript">
   function GetMap(){

    // Create the locations
    var Kaohsiung = new Microsoft.Maps.Location(22.649264, 120.326293);
    var Taichung = new Microsoft.Maps.Location(24.264493, 120.944152);
    var Taipei = new Microsoft.Maps.Location(25.029617, 121.543451);

    // Initialize the map
    var map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), {
    credentials: "Your key number",
    center: Kaohsiung,
    mapTypeId: Microsoft.Maps.MapTypeId.road,
    zoom: 8});

    // Create the entity collection with the polygon and pushpins at each corner
    var polygonWithPins = new Microsoft.Maps.EntityCollection();
    polygonWithPins.push(new Microsoft.Maps.Pushpin(Kaohsiung));
    polygonWithPins.push(new Microsoft.Maps.Pushpin(Taichung));
    polygonWithPins.push(new Microsoft.Maps.Pushpin(Taipei));

    // Add the shape to the map
    map.entities.push(polygonWithPins)
  }
  </script>
 </head>
 <body onload="GetMap();">
  <div id='mapDiv'></div>
 </body>
</html>

首先建立一個map元件,再來建立一個EntityCollection物件『polygonWithPins』
EntityCollection是一個群,EntityCollection可以加入Infobox, Polygon, PolylinePushpin  TileLayer, or EntityCollection.
polygonWithPins內包含了三個Pushpin圖釘物件建構方法又可帶入位置

透過map的EntityCollection將圖釘群們加入到地圖

透過HTML調用Mobile的Line

Line是一個可以透過網路去通訊的手機應用軟體,最近案子需要將這個功能加上去
但聽同學『螃蟹』說網頁版的已經關閉了,那只好開始找資料啦XDDDD

結果在BBS找到『[問題] 用javascript分享網頁至LINE』,底下有位大神TonyQ的回復非常有幫助,他說Line是走協定的,這句話真是點醒夢中人啊XDDD

找到了Line應用說明,但都日文啊!!!!!!
算了,當英文看XDDD


看起來Line不只可以傳文字,也可以傳圖片,但如果要指定對象我就不知道怎麼用啦XDDD

這次示範如何傳遞文字

Google Maps API 街景服務

街景服務是Google Map其中一個功能,街景服務可以讓我們從Google Map小人圖去取得街景


透過小人去取得的街景圖,可以更清楚的知道該路口附近有什麼明顯的指標,像我自己蠻常用這項服務的,自從Google Map出來後,就極少用過別家的地圖服務了!



有了街景圖可以讓我們在查詢街道時有一個相對位置,不過別以店家作為相對位置喔,店家何時會倒都不知道喔!到時候約會遲到或找不到地點就不要怪Google Map,要怪自己把目標用錯!

透過JavaScript讓HTML頁面互相傳值

最近在想如何將值傳遞到另一個網頁,大二有學過用PHP Post以及Get方式去傳遞
不過想嘗試用JavaScript傳遞,就上網找了一下方法

參考『在HTML頁面之間傳遞參數』文章,是透過JavaScript去分析網址內的內容,將內容的值取出來
我以該篇文章作為基礎,透過Button去傳遞值,讓第二個網頁的JavaScript去分析該網址值,並取出來用

第一個頁面的程式碼如下:

<!DOCTYPE html>

<html>
 <head>
  <meta charset="utf8">
  <title>測試1</title>
 </head>
 <body>
  <button onclick='location.href="index2.html?a=b&b=c&c=d"'>
   One
  </button>
 </body>
</html>

可以看得到我有一個Button,點擊之後會觸發onclick事件
觸發之後將網址轉到index2.html?a=b&b=c&c=d

問號後接的是我要傳遞的值
