OK here goes,
This one i find complicated to explain, but I have attached the project if you want to test it out what I am trying to say:-)
I have 1 app - 2 views.
1 UIWebView with a local html file with a form
1 ViewController with 2 buttons and 2 labels to interact with the view and then 2 labels that show the result when the buttons are pressed.
Now when I use the method stringByEvaluatingJavaScriptFromString and have set the content to import in the settings bundle I can only inject numbers, when I set letters in the settings app, they do not get injected. However when I inject it straight from the app there is no problem.
On the View Controller, I can retrieve both letters and numbers.
This would have me believe that the problem lies with the stringByEvaluatingJavaScriptFromString method.
Now I am not sure where the bug lies with this, because using that injection method and setting the letters or text in the ViewController works fine.
I need the webView, but when pulling content from the settings bundle it will only show the numbers in the textField. If you watch the console though, you will see that the letters and numbers are being recognized.
I am happy to give any additional details if I have left anything out.
Please if someone would be so kind to download the project and have a look, to see if what I am trying to say makes any sense, I would greatly appreciate that.
it is written with the 5.1 SDK
Kind Regards,
Jeff

Ok, after pulling out all my hairs I have found the answer:
%#", field01];
I had the code above, but for some reason that only lets through numbers or maybe they are integers anyway, no letters are being let through, yet to a label they are.
so I compared a hardcoded string to a dynamic string that I require and noticed that they hard coded string had the value between ' & ' so I put the %# between those and it fixed the problem.
so '%#'", field01]; fixed it all:-)
Cheers

Today I found that my Wordpress website has encountered a problem. There are two unexpected letters at the top of the page which can be found in the screen shot below. I can't find where it is from the raw files of Wordpress. I don't know what happened. Could somebody help me please?
Heya :)You might be using some website screenshot plugin. Deactivate that plugin and then check the output. :)
i've had the same problem a while ago only instead of an n or two n's in your case i had a v just at the same place as yours is. What helped for me where the following steps.
Check all files, header.php, template files, etc.
Deactivate and activate your plug-ins. Maybe even try the Wordpress Re-install function from the updates page. Don't worry none of your contents like pages, posts, etc will be lost.
Check your widgets, sidebars and other content blocks from the back-end but also the corresponding template files.
If you have a decent editor like in my case PHPstorm make use of the show history function. It makes searching a lot easier.
I hope just like i had your problem will be solved after taking these steps.
Im working through Django By Example and in one chapter a Jquery bookmarklet is built within a Django app so that a user can easily save jpg images from a website into their user profile area within the Django app.
Im not an experienced JS or Jquery programmer but I did some JS some years back and can read the code however the tutorial does give exact instructions on what to do which I have followed and although I have managed to get the bookmarklet button to appear in my bookmarks bar in Chrome, nothing happens when I click it when browsing a webpage with jpg images.
This is my local Django dashboard where the bookmarklet button is added to the bookmarks bar and this part works fine
and this is what it should look like when clicked on, this is the part where nothing happens for me
these are the relevant js files
https://github.com/davejonesbkk/bookmarks/blob/master/images/templates/bookmarklet_launcher.js
https://github.com/davejonesbkk/bookmarks/blob/master/images/static/js/bookmarklet.js
the only thing I can see that is different with these compared to the files that came with the book is the indentation is a bit off but for some reason the indentation does seem to have changed a bit when I uploaded to Git and they dont look like that locally. Is indentation important in JS?
I followed the same book with the same examples but didn't had any trouble. Make sure your dashboard.html file is referring to the correct javascript file. If nothing works try to add the bookmark manually, you can see how that's done over here http://www.howtogeek.com/189358/beginner-geek-how-to-use-bookmarklets-on-any-device/ it'll sure to work.
And answer to your last question, Indentation is not as important in JavaScript as it's in Python, as python doesn't use any curly braces "{}" or semi-colons ";". But you can write your entire javascript code in a single line and it'll work because your using curly braces everywhere to tell which line of code ends where.
I agree with all the above. In addition, the following:
Error I noticed in the book:
In bookmarklet-launcher.js the js function being called from bookmarklet.js is called myBookmarklet(), however there is no function called this way in bookmarklet.js. So, you may want to use the same name in both js files.
Practically speaking however, the bookmarklet will always work because, not finding a myBookmarklet function in memory, bookmarklet-launcher.js appends the bookmarklet.js script to the body element and, being bookmarklet.js a self-invoking function, its content executed (without the need it to being called). There are some additional interesting technicalities here (the key function in bookmarklet.js is not self invoking but it will anyway be always called because of the script checking whether jQuery is present...) but ok, this is more relevant for those busy with the mentioned book (Django 2 by example).
Check whether bookmarkled, once you click on it, is added to the
current webpage:
2.1. Open devtools (F12 on Chrome) and check e.g. in the html head element whether you find the newly added link element containing the css attribute and/or in the body element whether you find the script element containing the reference to the bookmarklet.js file.
2.2. Alternative: Add an alert message on top of the bookmarklet.js script so that it will be launched if it is correctly loaded. Example:
(function(){
alert('bookmarkled loaded!');
var jquery_version =...
Make sure you're trying to use it on a HTTP site only. Since you're serving from same protocol. HTTPS site would always tell say: There is a problem loadingbyour jquery. That's how I solved mine.
dude.I have solved the problems I met like you.
The most important thing is that noticing the syntax error(without warnings),mainly caused by ignoring blank.
for example, in the line:
jQuery('#bookmarklet .images').append('<img src="'+image_url+'"/>');
between #bookmarklet and .images should lie a blank space,because of jquery syntax rules(meaning to search tag with id of bookmarklet and search tag with class equaling images within result previously).
Another two places worth notice are codes containing #bookmarklet .images a and #bookmarklet #close,requiring blank spaces between filter condition.
That's where I found I made mistaks mainly after studying syntax of jquery.
You'd better compare your codes with codes already loaded up to github by someone to make sure there are no more little errors(such as spelling).
I've been struggling with this function for a few hours now and I can't get it to work in any way shape or form.
Assume my element location and image path are correct at all times. (Seriously, I've been going over this for the past 4 hours, it's not the element location and it's not the file path.)
What I started with was a sendkeys to the input element. This gave no error but caused the script to hang for ever; it wouldn't get past it and no images were being uploaded.
I literally tried every single possible variation of the sendkeys method listed on the first 4 pages of Google when looking for "Python PhanthomJS Selenium upload file sendkeys". Back to the drawing board.
Currently I am looking into executing a bit of JavaScript through Python to upload the file, though I have no idea how to go about this.
The page which I am trying to upload to has its form set to hidden and only shows a button which opens an upload dialog on normal browsers. I feel this is why sendkeys was not working.
Can anyone give me some input or suggestions as what to try next? Or how to execute some JavaScript from Python?
EDIT:
I learned how to execute JavaScript while using selenium in python and it saved my day.
To anyone coming here from google or whatever with the same problem, let me explain what I did:
The fact that my .send_keys() was hanging when sending keys to the input[file=input] element had me wondering before I made the topic but since the webdriver was still able to find the element I wasn't thinking too much of it and shrugged it off as something random. Later however I came with a suggestion that because it had a css type display: hidden !important the webdriver might have been able to find it, but not interact with it, and for some reason selenium just decided to hang itself instead of crashing / giving an error.
With that in mind I started browsing the docs and found the .execute_script() command, turns out we can use this to run a piece of JavaScript through the webdriver. Why I wanted this, is to see if the class styling had anything to do with it at all, how you ask? Well we can use the following line of code to change the class attribute of the input[type=file] element: document.querySelector("input").className="". This is not the most elegant solution since we are basically deleting the entire class responsible for the display: hidden !important styling. If the class were to hold more important data I'd suggest changing the class instead of renaming it to "" or deleting.
Moving on and trying it out, it showed the input button just like I hoped it would! After this I simply re-tried sending the keys and found no problems at all. There is no need for a click, submit or anything. driver.find_element_by_css_selector('input[type=file]').send_keys('path/to/file') However I did note that the way you structure the path seems to be pretty important. For example I am testing on windows and path/to/file did not upload or select any image for me, using path\\to\\file however, worked completely fine.
tldr:
driver.execute_script('document.querySelector("input")').className=""
followed by:
driver.find_element_by_css_selector('input[type=file]').send_keys('path/to/file')
Is what worked for me, and if you are in any alike situation your
variation on the script should upload the image as intended.
We run a Ruby on Rails 3.2 web application that uses a standard mix of rails and jquery.
Recently, we noticed a strange div element appearing in our production code. It seems to only show up when we render views with strings that also contain hyperlinks.
Here's an example:
We have a string in our view, that we want rendered as HTML:
"Try to search <a href='/search?q=hiring'>hiring</a>"
When we render the page in production though, we get the following:
"Try to search <a href="azarvuttcexyytzq.html" id="qqqqtra" rel="file">trufarwdstrzyzdyw</div>."
We're not sure why but the following div is being appended to our link:
<div style="display: none;">trufarwdstrzyzdyw</div>
What's strange is that we don't think that the file azarvuttcexyytzq.html exists on our servers, and we also found out that "file" is not an acceptable rel value for a hyperlink's relation attribute.
So, where could the div be coming from?
One thought is that it is coming from some analytics library in our system, since we're using Google Analytics. But we can't seem to confirm that idea or rule it out.
Does anyone know of a library that causes behavior like this?
Any help or insight would be appreciated.
If there is no developer who has done this (intentionally or otherwise) by appending a div with a random hyperlink in your application, then there is a high probability that your application server, some library or a gem you are using is compromised. It would be good to do an audit of your code/server and ensure that you are using the original version of all the gems and libraries and no malicious code is otherwise included in your app code.
We had the exact same issue, although intermittently, and it was Distil networks injecting in our case. To verify we took Distil out for the site and it worked like a charm!
Although, have yet to find how to get it working with Distil, will update the answer if/when we do
We had the same issue, our application behind Distil as well as in other comments.
If you use Distil, read this:
https://help.distilnetworks.com/hc/en-us/articles/235705127-Optimizing-Honeypot-Links-for-Pages-with-Inline-JavaScript
In short: Add the following comment near the top of your page (and above the JS) to force Distil injection to happen there: </a> -–> You can also add any other custom, a unique comment which Distil could use to inject the honeypot link code into.
I am using vim/gvim for 4 months already and now I found a way to use it's strengths.
My tags file is generated very well and here is a simple row in it.
my.namespace.classname /path/to/file.js /^my.namespace.classname = function(first_arg,$/;" f
Here is an example what i need to omnicomplete:
my.namespace.cla <- omnicomplete list with all classnames in the my.namespace
The above is the key to my problem, because it looks like omnicomplete searches only namespace without including "my." in front of it. So i see other element in the omnicomplete list and not my classname at all.
However, if i type :tag my.namespace.classname for example gvim opens the correct file at the correct position.
What is wrong and how can I make it work?
I've noticed that a lot of omnicomplete is not well developed. I've used the php omnicomplete and have had to go in and tweak a lot of it to get it working correctly. I recommend you download omnicomplete for javascript. Then add it to your plugins directory. Then make edits to it until it does what you want it to do.
Sorry I couldn't be of more help - but at least you won't go answerless any longer.
