Good morning guys,
I'm building a web app using Flutter, while testing it on iphone it working good in all versions except 15+,
i good message "a problem repeatedly occurred"..
this issue only happens for this screen
i tried many solutions to know why this happens.. one of them is to remove all this images (local images) and it works fine, so i tried to find solution for images and i followed this article but nothing happened
also i tried webGL2 issue in index file but unfortunately nothing happened too
this is my index file:
<head>
<script>
// The value below is injected by flutter build, do not touch.
var serviceWorkerVersion = null;
</script>
<!-- This script adds the flutter initialization JS code -->
<script src="flutter.js" defer></script>
<script src="https://unpkg.com/platform#1.3.5/platform.js"></script>
<script type="text/javascript">
let isSafari = /^((?!chrome|android).)*safari/i.test(platform.ua);
if (isSafari) {
HTMLCanvasElement.prototype.getContext = function (orig) {
return function (type) {
return type !== "webgl2" ? orig.apply(this, arguments) : null
}
}(HTMLCanvasElement.prototype.getContext)
}
</script>
<body>
<script>
let useHtml = false;
if (useHtml) {
window.flutterWebRenderer = "html";
} else {
window.flutterWebRenderer = "canvaskit";
}
window.addEventListener('load', function (ev) {
// Download main.dart.js
_flutter.loader.loadEntrypoint({
serviceWorker: {
serviceWorkerVersion: serviceWorkerVersion,
}
}).then(function (engineInitializer) {
return engineInitializer.initializeEngine();
}).then(function (appRunner) {
return appRunner.runApp();
});
});
</script>
i hope any one can give me a hand

I'm programatically generating HTML to show bing maps. The following generated HTML correctly marks the address, but the showTraffic() part seems to have no effect. For the sake of privacy, I've altered the address, omitted the bing-maps credentials, and truncated the end (which I've established is working) but otherwise this is the actual html generated.

var map, searchManager,trafficManager;
function GetMap() {
map = new Microsoft.Maps.Map("#myMap", {

});
geocodeQuery("1000 Dairy Ashford, Houston, TX 77077");
showTraffic();
}
function showTraffic() {
if (!trafficManager) {
Microsoft.Maps.loadModule("Microsoft.Maps.Traffic", function () {
trafficManager = new Microsoft.Maps.Traffic.TrafficManager(map);

trafficManager.show();

Microsoft.Maps.loadModule("Microsoft.Maps.Search", function () {

The issue is that the traffic module is loaded asynchronous, but your code is synchronous, thus the trafficManager is null when you call the show function. Here is a modified version of this function for you.
function showTraffic() {
if (!trafficManager) {
Microsoft.Maps.loadModule("Microsoft.Maps.Traffic", function () {
trafficManager = new Microsoft.Maps.Traffic.TrafficManager(map);
trafficManager.show();
});
}else{
trafficManager.show();
}
}
I am using jQuery 2.1.1, and have been using it to add 'clickable' to rows returned from a database using this:
<script type="text/javascript">
jQuery( function($) {
$('tbody tr[data-href]').addClass('clickable').click( function() {
window.location = $(this).attr('data-href');
});
});
</script>
That has been working fine. I have now added jquery-ias (2.1.2), and only the first page of returned results has clickable rows.
My jquery-ias code is as follows:
<script type="text/javascript">
$(document).ready(function() {
// Infinite Ajax Scroll configuration
jQuery.ias({
container : '.wrap', // main container where data goes to append
item: '.item', // single items
pagination: '.nav', // page navigation
next: '.nav a', // next page selector
negativeMargin: 250,
});
});
</script>
Jquery-ias is working fine, the pages are loading as needed, but the resultant rows are not clickable.
Inspecting the page in Chrome shows that the subsequently loaded rows have not had the clickable attribute added.
The relevant row in the php is this:
<tr class='resultsrow item' <?php echo "data-href='carddetail.php?setabbrv={$row['setcode']}&number={$row['number']}&id={$row[1]}'"; ?>>
All works fine if I use either, but how do I get them to play nicely together?
EDIT.....
OK, I have worked around it using the jquery-ias built-in pageChange event.
jQuery.ias().on('pageChange', function(pageNum, scrollOffset, url) {
var delay=1000;
setTimeout(function(){
jQuery( function($) {
$('tbody tr[data-href]').addClass('clickable').click( function() {
window.location = $(this).attr('data-href');
});
});
},delay);
});
This way when ias finds a page change, it waits a second for the page structure to load, and then applies the clickable class.
I can't see this working if it's waiting for images though... doesn't have to for this instance, but there's got to be a better way to do this.
Any pointers?
the better way would be to use the rendered event, for example:
jQuery.ias().on('rendered', function(item) {
var $items = jQuery(items);
$items.each(function() {
jQuery('tr[data-href]', $this).addClass('clickable').click(function() {
window.location = $(this).attr('data-href');
});
});
});
I am developing an application on iOS. I am using Phonegap and jQuery Mobile for my application. Currently I am retrieving an image's URI when the user clicks an image or selects it from a gallery using Phonegap and saving the URI locally. I need to submit these images on a server by converting them in a Base64 string. In order to convert them into Base64 I am using the Phonegap-provided example.

In the example, instead of "readme.txt" I am passing a local image URI for testing on the simulator fileSystem.root.getFile("image.png", null, gotFileEntry, fail);. However I get the following error:
Error in error callback : File2 = TypeError:'undefined' is not an object.
I also tried the absolute path for the image but got the same error. I do not understand what can go wrong? Am I missing anything ? I need to crack this ASAP.
Any help is highly appreciated.
Thanks.
I think that your file must be created first, if you're sure that this is the case, you can get access to it by specifying the second argument of getFile methode like this:
fileSystem.root.getFile("image.png", {'create' : false}, gotFileEntry, fail);
The {'create': false} will tell phonegap to not create the file, which is the default case I think.
i'm busy with a school project and I have to build a web app. One function that I want to use is Google Maps and HTML5 Geo Location to pin point what the location of the mobile user is.
I have found this HTML5 Geo Location function on http://merged.ca/iphone/html5-geolocation and works very well for me. However, I want the adress data to be placed into a form so that I can submit it to my database when a mobile user Geo locates his position. This causes the marker to be saved and can be viewed on a global website.
Who know how to get the "Your address:" data loaded into a input field of a form?
Below you can find my Html file. Maybe somebody got a better suggestion perhaps?

You have to use JavaScript to set the value of address input field, this way
1- Add name attribute to the form and input.
2- document.formName.inputName.value=place.address;
Good Luck
I'm new to mediaelements.js
at the end of my video, I wish that the user is redirected to another page
I have tried something like
<script>
$(function(){
$('audio,video').mediaelementplayer({
success: function(player, node) {
window.location = "http://google.com";
});
}
});
});
</script>
but I have not been successfull at all, maybe someone would have an idea
This worked for me. 'player1' is the id of the video
<script>
new MediaElement('player1', {
success: function (mediaElement, domObject) {
// add event listener
mediaElement.addEventListener('ended', function(e) {
//Do Stuff here
//alert("sometext");
window.location = "http://google.com";
}, false);
},
});
</script>
The code I posted was for the media element player. I looks like you're using the video.js player in the link you posted. I'm not sure how that would work but I did find this... help.videojs.com/discussions/questions/26-redirect-to-url-once-video-has-ended
