How can I show a HTML+CSS file in a Flutter widget, while being able to manipulate the HTML or CSS (in file) and viewing the changes live?
Manipulating HTML:
I could use JavaScript to manipulate the HTML DOM of a loaded webpage, probably through localhost? Is there a better way to do it instead?
Manipulating CSS:
Searching around the internet I find JavaScript like "dom.getElementById('something').style.color = color.red". Though, how could I go for loading css on every change of the css file, if possible?
I hope my question is not vague. Please let me know of any issues or suggestions on this question.
The app is meant for desktop installs, though I wouldn't mind switching to working with flutter-web if need be.
Kind regards.
I should create a moodle wiki and I have got some sections on my wiki-page. Now I would like to create a table of contents where The user can jump between the sections like on Wikipedia.
What I tried:
section1
...
<h2 id="section1">Section1</h2>
The problem I got is that when I save the page the id property will be removed from the tags
If you are using one of the latest version of Moodle, it is possible to make the HTML ids stick if you add you HTML markups within the Wiki HTML editor.
This has to be the ultimate change you do to the document. Once you have your HTML correctly tagged, directly hit the Save button without going back to the editor's preview mode. They should be available in the Wiki after that.
If you need to edit the page again, be sure to keep a local copy of your HTML structure, in order to avoid having to add the HTML markups again. They will be removed everytime you edit the page or if you switch from the HTML editor to the WYSIWYG preview mode.
I have created a XML file using R-exams out of just a single exercise to be imported to Moodle. I would like to view it before uploading it in the Moodle question bank. I tried to open it with Firefox and I can see some code but not the output and a message appear saying that the XML file does not seem to have a style sheet associated to it. Is there a way to find this style sheet and to see how the question comes out just using a browser like Firefox or Chrome?
To emulate how the R/exams exercises are converted to HTML by exams2moodle() and how Moodle displays mathematical content, it's best to use
exams2html(..., converter = "pandoc-mathjax")
In recent versions of R/exams the resulting HTML file then automatically loads the MathJax Javascript that enables correct rendering of mathematical content in all modern browsers (including Google Chrome). See also http://www.R-exams.org/tutorials/math/ for some general advice about math in HTML.
To the best of my knowledge there is no tool that would quickly display Moodle XML files in such a way that you can easily assess them.
I don't manage to get the Image Tools plugin to actually upload the images to the server. I upload images with the jbimages plugin with no problem. But when a picture is edited with the Image Tools, although there's the uploading bar, which gets to 100%, it seems that it's only uploaded as a blob. The page calls the tinymce.activeEditor.uploadImages() function when submitting the form data, but it doesn't work.
I use the 'postacceptor.php' file from the example (defined in 'images_upload_url') and the 'images_upload_base_path' is defined as well.
The files are not uploaded to the server, and the img src remains a blob.
What could the problem be?
Thanks!
What debugging have you done in your PHP code? Is the code being triggered? Does the file appear in the posted content? You need to narrow down where in the process things are failing.
Is the issue that TinyMCE is not posting the edited image or is the issue that the image is posted and the PHP code is not properly saving the image and returning valid JSON?
How did you configure TinyMCE?
Does an edited image get posted to your server code?
What is in that form post?
If you disable the jbImages plugin does that change anything?
Without more details it will be very difficult to help you figure this out.
Network analysis by Chrome when page loads
I would like to export this data to Microsoft Excel so that I will have a list of similar data when loaded at different times. Loading a page one time doesn't really tell me much especially if I want to compare pages.
if you right click on any of the rows you can export the item or the entire data set as HAR which appears to be a JSON format.
It shouldn't be terribly difficult to script up something to transform that to a csv if you really need it in excel, but if you're already scripting you might as well just use the script to ask your questions of the data.
If anyone knows how to drive the "load page, export data" part of the process from the command line I'd be quite interested in hearing how
from Chrome 76, you have Import/Export buttons.
I was trying to copy the size data measured from Chrome Network and stumbled on this post. I just found an easier way to "export" the data out to excel which is to copy the table and paste to excel.
The trick is click Control + A (select all) and once the entire table will be highlighted, paste it to Microsoft Excel. The only issue is if there are too many fields, not all rows are copied and you might have to copy and paste several times.
UPDATED: I found that copying the data only works when I turn off the filter options (the funnel-looking button above the table). – bendur
Right-click and export as HAR, then view it using Jan Odvarko's HAR Viewer
This helps in visualising the already captured HAR logs.
I came across the same problem, and found that easier way is to undock the developer tool's video to a separate window! (Using the right hand top corner toolbar button of developer tools window)
and in the new window , simply say select all and copy and paste to excel!!
In Chrome, in the Developer Tools, under Network, in the Name column, right-click and select "Save as HAR with content". Then open a new tab, go to https://toolbox.googleapps.com/apps/har_analyzer/ and open the saved HAR file.
Note that ≪Copy all as HAR≫ does not contain response body.
You can get response body via ≪Save as HAR with Content≫, but it breaks if you have any more than a trivial amount of logs (I tried once with only 8k requests and it doesn't work.) To solve this, you can script an output yourself using _request.contentData().
When there's too many logs, even _request.contentData() and ≪Copy response≫ would fail, hopefully they would fix this problem. Until then, inspecting any more than a trivial amount of network logs cannot be properly done with Chrome Network Inspector and its best to use another tool.
You can use fiddler web debugger to import the HAR and then it is very easy from their on... Ctrl+A (select all) then Ctrl+c (copy summary) then paste in excel and have fun
I don't see an export or save as option.
I filtered out all the unwanted requests using -.css -.js -.woff then right clicked on one of the requests then Copy > Copy all as HAR
Then pasted the content into a text editor and saved it.
I had same issue for which I came here. With some trials, I figured out for copying multiple pages of chrome data as in the question I zoomed out till I got all the data in one page, that is, without scroll, with very small font size. Now copy and paste that in excel which copies all the records and in normal font.
This is good for few pages of data I think.
In more modern versions of Chrome you can just drag a .har file into the network tab of Chrome Dev Tools to load it.
To get this in excel or csv format- right click the folder and select "copy response"- paste to excel and use text to columns.
You can try use Haiphen, which is a chrome extension that allows you to analyze network traffic and what API calls a web application is making.
