[英]Ionic Cordova $http POST data works well in browser but does not work in my android phone
[英]Ionic Cordova SQLite works well on browser but does not work persistent in Android device
我正在開發離子科爾多瓦混合應用程序。 當我使用瀏覽器進行測試時,應用程序運行良好。 但是我在我的真實設備中對其進行了測試,但它並不是非常持久。 這意味着SQLite有時效果很好,有時效果不好。 以下是我的代碼:
app.js
.run(function($ionicPlatform, $cordovaSQLite) {
$ionicPlatform.ready(function() {
if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
cordova.plugins.Keyboard.disableScroll(true);
}
if (window.StatusBar) {
StatusBar.styleDefault();
}
db = window.openDatabase("chatChannel.db", "1", "Demo SQLite Test", "2000");
$cordovaSQLite.execute(db, "CREATE TABLE IF NOT EXISTS chat_channel(id interger primary key, chat_room text, last_text text, username text, chat_channel text unique)");
$cordovaSQLite.execute(db, "CREATE TABLE IF NOT EXISTS chat_content(id integer primary key, content text, channel text, chat_flag integer, username text, date timestamp)");
});
controller.js
var query = "SELECT * FROM chat_content WHERE channel=? ORDER BY date";
var promise = $cordovaSQLite.execute(db, query, [subscribeChannel]).then(function(result){
for(i=0; i<result.rows.length; i++){
$scope.messages.push(result.rows.item(i));
console.log(result.rows.item(i));
}
});
請嘗試以下操作:
1.通過將它們放置在index.html文件的底部,最后加載ng-cordova-min.js或ng-cordova.js和cordova.js文件
2.在您的app.js文件中,數據庫初始化應為第一行,即
var db = null;
應該是頂部的第一行。 仍然在您的app.js文件中,
db = window.openDatabase("chatChannel.db", "1", "Demo SQLite Test", "2000");
應該是平台就緒功能的第一行。 您的代碼應在app.js文件中類似這樣;
.run(function($ionicPlatform, $cordovaSQLite) {
$ionicPlatform.ready(function() {
db = window.openDatabase("chatChannel.db", "1", "Demo SQLite Test", "2000");
$cordovaSQLite.execute(db, "CREATE TABLE IF NOT EXISTS chat_channel(id interger primary key, chat_room text, last_text text, username text, chat_channel text unique)");
$cordovaSQLite.execute(db, "CREATE TABLE IF NOT EXISTS chat_content(id integer primary key, content text, channel text, chat_flag integer, username text, date timestamp)");
if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
cordova.plugins.Keyboard.disableScroll(true);
}
if (window.StatusBar) {
StatusBar.styleDefault();
}
});
})
