Ionic hybrid app, saving application state/data on exit

南笙酒味 提交于 2019-12-08 03:18:54
问题 I'm building an app using the ionic framework with angular js, and I'm a little confused on what the best way is to go about saving and restoring the users state when they exit the app. For example, in iOS if the user manually terminates the app, or if the phone is turned off for some reason, I want the user to be able to open my app up and still be at the same place and see the same data, even if they are offline. I have been using HTML localstorage, and understand how to save and restore

Remembering a jQuery draggable tool palette position between page refreshes

喜夏-厌秋 提交于 2019-12-08 01:48:44
问题 I have a tool palette which shows up when an admin user is logged in to a site. The palette is draggable (via jQueryUI.draggable) and I would like it to remember the position between pages/refreshes... Is there a standard way of doing this, or a plug-in I should be using, or do I need to roll my own (via cookies or something)? 回答1: Cookies are a fine option - you can use the functions by PPK like this: $('#palette') .css({ top: readCookie("palletteY")*1, left: readCookie("palletteX")*1 })

AngularJs ui-router $location or $state?

左心房为你撑大大i 提交于 2019-12-07 18:43:53
问题 How can I transform this: $location.path('/app/home/' + id).search({x:y}); to this: $state.go('/app/home/' + id).search({x:y}); I tried, but I actually can't get enough information how to achieve that... 回答1: There is nice documentation (while deprecated, still really clear) : $state.go(to [, toParams] [, options]) Let's say that the state definitions are looking like this: .state('app', { // parent app url: '/app', ... }) .state('app.home', { url: '/home/:x', // the param named x ... Then

Why does React throw an error when setState method used in a class constructor?

限于喜欢 提交于 2019-12-07 16:29:10
问题 I know that an error is thrown when setting state for a component not yet mounted. Which explains the error I get from using setState function as oppose to explicitly and directly setting the state. import React, {Component} from 'react'; class SearchBar extends Component { constructor(props) { super(props); this.state = {term: ''}; // -> seems to be the agreed means to set initial state // this.setState({term: ''}); // -> generates an error } render() { return ( <div> <input onChange={event

ASP.NET Page.Cache versus Page.Application storage for data synchronization?

旧巷老猫 提交于 2019-12-07 15:20:26
问题 Both Page.Cache and Page.Application can store an application's "global" data, shared among requests and threads. How should one storage area be chosen over the other considering scenarios of data synchronization in the multi-threaded ASP.NET environment? Looking for best practice and experienced recommendation. 回答1: If the data is stable during the life of the application must always be available and must not be purged better store it in HttpApplicationState . If the data not necessarily is

How can Azure maintain APPLICATION state?

早过忘川 提交于 2019-12-07 11:14:43
问题 I know how Azure preserves SESSION state -- I've implemented it in my app using AppFabric based on Neil MacKenzie's Microsoft Windows Azure Development Cookbook . However, that approach based on AppFabric apparently does not preserve APPLICATION state (e.g. Application["name"] = MyObject ), which my app needs. I suspect I will need to use Azure Tables, but that will require recoding. So before going down that path, I'd like to know if there is a simpler approach to preserve application state,

What's the state of a pressed Tab in Android

♀尐吖头ヾ 提交于 2019-12-07 07:48:30
I'm trying to get my tabicon to change when a tab is pressed (i.e. when it changes color when you press the tab, but haven't released yet).

Hiding parent state view from child state view in angularjs, best practices?

吃可爱长大的小学妹 提交于 2019-12-07 03:09:58
问题 'update-approved-product-campaign-ad' this is the child state of 'product-campaigns.product-campaign-detail' when i call child state through ui-sref parent state view gets called along with child state view which i don't want. I want only child state view. 回答1: i solved this issue by wrapping the parent view with <div ui-view=""> This will override the ui-view with the child when navigating to a child state, otherwise it will contain the patent state's view. 回答2: This can be done using view
