I want to use custom images for tab bar icons, as set in this line using this extension: https://github.com/squerb/cordova-ios-tab-bar (imageName is passed through the extension from the javascript):
item = [[UITabBarItem alloc] initWithTitle:title image:[UIImage imageNamed: imageName] tag:tag];
I'm struggling to work out where I need to put the image in my Cordova project so that it's accessible by the native code. If indeed that's possible.
I've tried this:
item = [[UITabBarItem alloc] initWithTitle:title image:[UIImage imageNamed:#"www/assets/failed.png"] tag:tag];
But that results in this error:
2016-02-01 15:52:02.894 MovidiamWeb[2527:1070985] -[NSNull length]: unrecognized selector sent to instance 0x1a1e33ea8
2016-02-01 15:52:02.897 MovidiamWeb[2527:1070985] *** WebKit discarded an uncaught exception in the webView:decidePolicyForNavigationAction:request:frame:decisionListener: delegate: <NSInvalidArgumentException> -[NSNull length]: unrecognized selector sent to instance 0x1a1e33ea8
The second form, referencing a path that is visible in xcode project directory, in cordova's case, 'www/images/whatever.png' should work fine, just had to give it a few goes before it started working for some reason.

There is an image open in the Preview application, and it is unsaved.
I have tried this code, by building and running a standalone script in Script Editor:
var preview = Application('Preview')
var preview.documents[0].close({ saving: true, savingIn: '/Volumes/USB Drive/Untitled-Image.png' })
I see this in the logs
app = Application("Preview")
app.documents.at(0).Symbol.toPrimitive()
--> Error -1700: Can't convert types.
app.documents.at(0).Symbol.toPrimitive()
--> Error -1700: Can't convert types.
However, I'm not sure I'm reading the docs correctly, and I'm not sure how to further debug this code. A satisfactory alternative here would be to send a keystroke to save and click the Save button.
What can I do to persist the image in Preview to a file?
One can declare paths speculatively in JavaScript using Path('...'), and then use the save command to save the image to the file that will be created at that path:
Preview = Application('com.apple.Preview');
ImageFilepath = Path('/Users/CK/Pictures/Preview_SavedImage.jpg');
Preview.documents[0].save({ in: ImageFilepath });
This code worked for me.
var preview = Application('Preview')
var photo = preview.documents[0]
photo.close({ saving: 'yes', savingIn: Path("/Path/To Some/file_name.png") })
Upon execution, in the Replies log of Script Editor window, something slightly different from the question sample is logged.
app = Application("Preview")
app.close(app.documents.at(0), {savingIn:Path("/Path/To Some/file_name.png"), saving:"yes"})
I was able to figure this out by studying the scripting dictionary for macOS Mojave 10.14 as well as the Release Notes for JXA; there is a similar example under Passing Event Modifiers section of that.
From the Script Editor scripting dictionaries, this is the entry for the close method in the Standard Suite:
close method : Close a document.
close specifier : the document(s) or window(s) to close.
[saving: "yes"/"no"/"ask"] : Should changes be saved before closing?
[savingIn: File] : The file in which to save the document, if so.
Note the key differences between the working code here and the code in the question:
Specify a Path object when passing the savingIn option to close.
Specify a the saving option as one of "yes", "no", or "ask" (not true).
If you're new to JXA, Automator, and/or Script Editor for Mac, checkout the JXA Cookbook.
If this answer helps you, you're probably having a bad time, so best of luck!
I'm developing an app which has to:
Open a webpage in a Webview;
Check the available links and click on the link which contains a certain word (I.e. http://www.domain.com/myword); after the click, the link will open in the same webview.
I tried the following code but it' giving this error "E/Web Console(6169): Uncaught SyntaxError: Unexpected identifier at null:1".
WebSettings myBrowserSettings = myBrowser.getSettings();
myBrowserSettings.setJavaScriptEnabled(true);
Log.d("Stefano", "JS enabled");
myBrowser.loadUrl("javascript:document.getElementsByTagName('a[href*='myWord']')[0].click();");
Can you help me?
Consider that I'm using document.getElementsById('My ID') in another part of the app (to click a button) and it's working correctly; but here, i'm not able to get getElementsByTagName working.
Thanks for your time and availability
UPDATE:
I replaced 'a[href*='myWord']' with \"a[href*='myWord']\" as suggested by the user but now i have this error E/Web Console(2683): Uncaught TypeError: Cannot call method 'click' of undefined at null:1.
Any idea?
'a[href*='myWord']'
This reads as string 'a[href*=', var myWord, string ']'
Presumably, you are trying to do this:
\"a[href*='myWord']\"
I am using a JavaScript error logging tool to log any JavaScript errors on my mobile site and I am seeing a large number (22,000 in under a month) of this error:
Uncaught TypeError: Cannot read property '_pmh' of null
I can see from the addthis_widget.js code that it is originating from that script.
I can also tell that it only affects mobile Android and Google Chrome browsers, these in particular:
Android 4, Android 4.1, Android 4.2, Chrome 11, Chrome 18, Chrome 25, Chrome 26, Chrome 27, Chrome Mobile 18, Chrome Mobile 25, Chrome Mobile 26
I am using the following external JavaScript include:
http://s7.addthis.com/js/250/addthis_widget.js#username=xa-4b6adff375a64db9
and have the following configuration object set:
<script type="text/javascript">
var addthis_config = {
data_ga_property: 'UA-18721873-1', // real GA profile hidden for privacy purposes
data_ga_social: true
};
</script>
Is there anything I can do to prevent this error from occuring so many times on these browsers?
I have located the cause of this issue and it is down the following code.
if (window.addthis) {
window.addthis = null;
window._adr = null;
window._atc = null;
window._atd = null;
window._ate = null;
window._atr = null;
window._atw = null;
}
This was an attempt to cleanup the objects lying around when moving between pages dynamically to prevent memory issues.
addThis now provide support for this problem, their support department sent me the following link:
http://www.addthis.com/blog/2013/05/07/a-brief-history-of-using-addthis-dynamically/#.Uklx4RCKyas
and the following explanation/information:
Along with other information from my peers and such, I've come up with
the proper code which should be executed when moving from virtual page
to virtual page such as in your mobile application. Rather than
nulling any of the AddThis related objects, they must be left alone.
When the page URL or Title (or any other AddThis configuration option)
that you want to be used by our buttons changes, you should execute
our method:
addthis.update(type, key, value)
It takes the three parameters: type, key, value.
Type is either "share" or "config". The key is the same key you would
set according to our API documentation. What you likely need to know
are just the two keys: "url" and "title". The value is of course the
value you want those options to have.
After you have updated all of the options you need to update using
that method, you need to invoke this method:
addthis.toolbox(cssSelector)
The cssSelector is usually going to be ".addthis_toolbox" but if for
some reason you don't want to refresh all of your toolboxes, you can
be more specific about it.
Once you have made those changes to your code, I believe that our
tools will work properly for you and that there will be no more "null
object" related javascript errors.
You can look at this JSFiddle to see an example of dynamically
changing content: http://jsfiddle.net/j5addthis/r6Utv/
I'm having the same issue, but it appears that there was, at one point, a fix to your specific case above by simply upgrading the script that you're using from addthis to version 3.0 by changing this:
http://s7.addthis.com/js/250/addthis_widget.js#username=xa-4b6adff375a64db9
To this:
http://s7.addthis.com/js/300/addthis_widget.js#username=xa-4b6adff375a64db9
Read more here: http://support.addthis.com/customer/portal/questions/1021465-addthis-widget-js-throwing-cannot-read-property-pmh-of-null-error-on-android-and-chrome
Note though, as I mentioned above, my issue continues to persist even with version 3.0 despite the AddThis help desk stating that should work.
I'm trying to install the phonegap plugin for Facebook by Jos downloadable here: https://github.com/jos3000/phonegap-plugins/tree/master/Android/Facebook
I've got the folder structure set up like this:
src/com/facebook/android/*.java
src/com/hipsnip/plugins/facebook/FacebookAuth.java
src/com/my_app/app/App.java
libs/phonegap-1.0.0.jar
/res/xml/plugins.xml
assets/www/index.html facebook.js phonegap-1.0.0.js
I've added the plugin to the plugin.xml file like so:
<plugin name="facebook" value="com.hipsnip.plugins.facebook.FacebookAuth" />
I've added the facebook.js to my index.html, and have the following function (which gets triggered by pressing a button):
function facebook_login()
{
var appId = "1234"; // this is your facebook app id change me
window.plugins.facebook.authorize(appId,function(res){
alert(res.name);
});
});
});
}
The app opens up a new browser window (I suspect that's what it is) but all it displays is my application without running javascript.
LogCat shows the following error:
file:///android_asset/www/index.html: Line 95 : TypeError: Result of expression 'window.plugins.facebook' [undefined] is not an object.
Thanks for any help you can give (I suspect it has to do with the way that I've set up the folders, or the way I've added the plugin.xml, but I really don't have a clue)!
PhoneGap now has an official Facebook plugin. Use that.
I'm having an extremely difficulty time getting the flowplayer to show up and the worst part is I have no idea what is wrong because I'm not getting any error messages!
I have an external javascript file:
C:/desktop/mysite/js/jq/plugins.js
calling $f() from:
C:/desktop/mysite/thirdparty/flowplayer/flowplayer.js
the swf files also live there...
I'm working on file/desktop (no localhost or webserver)
$(video.id).flowplayer("thirdparty/flowplayer/flowplayer-3.1.15.swf", {
clip:{
....
},
// min Flash version
version:[9,115],
// older versions will see a custom message
onFail:function(){
alert("Failed!");
},
onError:function(errCode,errMsg){
alert(errCode+errMsg);
}
});
I don't know what path to use for the SWFs to get them to load, is the path relative to the javascript (plugins.js) that calls $f() or is it relative to the path of the flowplayer.js ??
bangs head on wall
Why not use the absolute path?
$(video.id).flowplayer("file://c:/desktop/mysite/thirdparty/flowplayer/flowplayer-3.1.15.swf"...
replace thirdparty/flowplayer/flowplayer-3.1.15.swf with thirdparty\flowplayer\flowplayer-3.1.15.swf
if you are planning to put that on a web page then change the slashes back to forward slashes.
