ionic2 Angular2 import/export JSON data

What I mean by import/export data and why it needs to be implemented..

1) I want my app to work offline – store data added by user while offline.

2) The data stored in JSON format.

3) I want that JSON data to export in a file and stored in phone memory.

4) Multiple files will be created.

5) When user get internet – the exported file will be imported and that JSON object to be stored in datastore – any server like Firebase.

Please suggest how this could be possible in Ionic2, Angular2.

  • The JSON object to be export in file – while offline.

  • Later that file will be imported and the data to be save over server.

Yet everything is working while online.
Due to large collection of data AngularFire2 like offline library wasn’t working properly.

Please suggest possibilities..

ng-include of inline SVG does not display gradient except in Chrome

I have setup an NG-INCLUDE which loads an SVG file that has classes “hover_color_change” so that the correct polygons can have their fill attribute updated: <div class="prod-illustration-div col s12 m8"> <div class="prod-svg-wrapper" ng-include="'/img/illustrations/illustration_' + productIdObj.illustration + '.svg'" onload="defaultFill(productIdObj.colors)"> </div> </div> I then have color swatches which trigger the $scope.hoverColorText() which calls the updateSVGFill() method to display the SVG fill matching the hover color and creates a shading of gradient so it’s not a solid color. Here is live link – WORKS IN CHROME In Chrome it works, however, in Safari, FF, Edge, it does not. I referenced this suggested answer which suggests referencing the ID attribute, which I believe I am already doing: $scope.defaultFill = function (colors) { if (colors) { var defaultCol...

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality - development

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality I would really like to know if there is a way like MS Word mailmerge functionality that can be done using PHP and Mysql data. Like i have address data in MySQL (suppose 10 numbers) and through PHP i want to insert that address data in a pre-defined letter head area. And it will automatically generate 10 different letters with same content but different address in PDF. Can it be done? Any start up point will be helpful. As I am working on Laravel so any snippet of that sort will also be useful. Thanks in advance. from Laravel Questions and Answers https://laravelquestions.com/php/using-php-and-mysql-data-to-generate-pdf-letters-like-in-ms-word-mailmerge-functionality/ via Lzo Media

I just found the problem related about the $scope.isSearching, when we show like above, the ng-click doesn’t trigger. But if i do : <ul class=...
