问题 I am using websql, but problem is, not finding any date functions in websql. I have date stored in the format Mon Apr 09 2012 15:23:54 GMT+530(India Standard Time) , and I want the query result in the format 04/09/2012 .

问题 We're currently developing a iPhone/Android app with phonegap (and sencha touch), with a WEBSQL Database. Everything is working fine on the iOS and on all the Android versions, except for Ice Cream Sandwich. The problem until now has nothing to do with design, it's because the database is not loaded. The different tables are created, but without its content. This gets me to the question, is WEBSQL supporting apps on Ice Cream Sandwich? Or did anyone have a similiar problem with this on ICS 4

问题 My company is currently transitioning to a new architecture, as well as a model that provides services to mobile devices. Our application was traditionally web based ( HTML5/CSS3/JS/PHP/MYSQL ), so we want to be able to port it to mobile platforms without having to reinvent the wheel ( Cordova ), as well as to desktops in a standalone fashion ( AppJS ) so that we don't have to worry about browser-dependent bugs. We are also transitioning away from PHP to NodeJS to make this more feasible. The

问题 Consider: var globalvar; function viewyearmain() { db.transaction(function (tx) { tx.executeSql('SELECT * FROM BUDGET WHERE holdingtype="month"', [], function (tx, results) { var len = results.rows.length; msg = len; globalvar = msg; }, null); }); if (globalvar>0) { alert("ROWS FOUND"); } else { alert("ROWS NOT FOUND"); } } The problem is that ROWS NOT FOUND appears because the transaction has not completed by the time the if statement is reached. 回答1: An asynchronous callback is not

问题 A quick overview of what I have, and the problems that are associated with it. I have a HTML5 app that I am going to run as a native app using PhoneGap. It is a small data collection application for the local field research station. The problem with this field station is that they are prone to loosing a signal to transmit data; thus I want to store the data on the device for later use (or to send it to a server). Data that needs to get saved is the following: *User Name (string) *Transect

问题 I am trying to create database and tables in background.js file of Chrome but somehow it's not being created. When I see in Chrome Inspector > Resources > WebSQL, I find nothing. Code is given below: function fetchData(){ var xhr = new XMLHttpRequest(); xhr.open("GET", "http://localhost/php/fetch.php", true); xhr.onreadystatechange = function() { if (xhr.readyState == 4) { // JSON.parse does not evaluate the attacker's scripts. var resp = xhr.responseText; if(resp != null) { var json = JSON

问题 We are trying to migrate a hybrid app from UIWebView (iOS < 8) to WKWebView (iOS 8), but we are getting SecurityErrors when trying to store stuff using the DOM WebDatabase API (i.e. 'web sql databases'). The following throws an error if the index.html has been loaded from a bundled file with the app // throws SecurityError: DOM Exception 18 var db = openDatabase('mydb', '1.0', 'key value store', 1); The same code works fine with UIWebView. I can fallback to using Local Storage for some reason

问题 I am developing an HTML5 web app that is run from a WebView inside an iOS app. Once the users upgrade to iOS7, localStorage stops working and the app (which uses jQuery/jQuery Mobile) just shows the spinner. I've run some tests using Modernizr and it does not detect support for localStorage in the WebView within the app. This is strange, because it works fine in Safari on the iPad with iOS7. Has anyone else run into this issue or have a magical fix? The only client-side web storage API that
