I have a HTML page that displays a SVG element (a Business process diagram) using some javascript libraries. A String variable, say 'str' needs to be given to html function.
After reading this, I plan to use widgets. So far I understand that I need to copy all scripts to Widgets: Test. For creating the hook, I write
{{#widget:Test|str=UserTask_1}}
The problem is that UserTask_1 is a variable as well. It is different each time.
Can someone help how can I add this dynamic information to my hook? This hook is a hyperlink from a previous page. In the previous page, I send the str=UserTask_1 through JavaWiki Bot.
PS: I have come-across SMW for first time. Please excuse if my language is not very technical at the moment.
Thanks.

I started learning Rub/Rails about a month ago, but haven't been able to find many resources specific to my issue.
I understand that in HTML/JS you can do something like:
let elements = document.getElementByName('name')
Is there a way in rails to get elements that share the class/id/name?
How can we interact with those elements? for example: if a div with a specific name already exists, append some data from our rails application to that div instead of creating a new one.
Thank you in advance.
Unless I'm really missing the point, what you're asking for isn't possible.
DOM manipulation (using Javascript) is something that happens client-side, in the browser; the browser requests a page, the server responds with an HTML document, and then the browser builds the DOM and we go from there, running Javascript, and potentially inspecting and manipulating the DOM.
Ruby on Rails is server-side; in the above description, it would be involved in the "the server responds" step, but there is no DOM at that point; it's simply generating an HTML document, using models / a view / a controller.
I am trying to write a bit of code to read a sensor and, with my ESP32 make a webpage that will display the value.
But on a gauge with a "needle" ( think speedometer type of thing ) like output, I can make variables in CSS and I can make the gauge in CSS and display in HTML fine.
I can change the value of the gauge by changing the CSS variable BUT I want to be able to pass this varibale to CSS from my HTML file.
This is so I can process the HTML page on my ESP32, updating the value of the sensor and display it, I can't seem to get an option of updating CSS varible through HTML.
I would like to rather stay away from JavaScript to be hoest, I'm already learning CSS and HTML to make this work, but if need be I will do it.
Or could I do this in PHP perhaps ?
Any advice ?
If you want to make this dynamic, you have no other option rather than to recur to JavaScript in combination with what you are using. From what I understand it's something like either a percentage value or a rotation degree value you are toying around with.
What I can recommend for your specific case is to use an inline style to change the position of your indicator.
Something like:
<div style="width: 99%;"></div>
It would help if you share with us what you have as code till now.
Also, from what I understand you are still new to this sort of coding, but something that would probably work really well for you could be Socket.io you just assign a port that receives information and configure it, and you could configure your ESP32 to send info to that port I suppose, not really familiar with that part though.
If you want really real time value refreshing with esp32 on its own web you have to use websockets.
I don't know what server library you using, but there are a couple of websocket libaries out there.
I recommend ESP32_AsyncWebserver from Me_no_Dev. This is a fully async webserver implementation, and it is containing the async websocket too.
If you succesfully implemented that to your project, and loaded your static html file with the gauge you mentioned, on runtime of the esp32 you can send websocket text messages to the front-end javascript code. Once you received the messages on the javascript side you can easily update anything from there.
If you interested in this more, i will write some code for you in here. Just let me know.
I'd like to achieve the following and I'm looking for ideas. I have a document and I want to represent/transform this content in/to a nice SAPUI5 framework. My idea is the following: a split app with having the paragraph titles in the master view (plus a search function on top) and the respective content in the detail view.
I'd like to know from you if
a) you might want to share your ideas and hints on alternatives.
b) this can be achieved within one single file (i.e. all the code for the split app and document content in one html) and maybe using pure html code (xml also feasible) - against the background of easily handing a large amount of text available in html.
c) if you happen to have/know a reusable template.
Thanks in advance!
An interesting question. I went through a similar exercise once, re-presenting my site with UI5.
To your questions:
(a) I would think that the approach you suggest is a good one
(b) You can indeed include all the app in a single file, I do that often by using script templates, even with XML Views. You can see some examples in my sapui5bin repository, in particular in the SinglePageExamples folder. Have a look at this html file for example: https://github.com/qmacro/sapui5bin/blob/master/SinglePageExamples/SAP-Inside-Track-Sheffield-2014/end.html
What I would suggest is, rather than intermingle the document content and the app & view definitions, maintain the content of your document separately, for example, in XML or JSON, and use a client side model to load it in and bind the parts to the right places.
Posted this in another forum, thought of posting here as well.
I need to send a jsp/html page, that is generated as a report, as an email. How do I do it?
If it's a static html page, I can hard code it as a string variable and set it as one of the arguments in the setContent method as follow:
message.setContent(stringValue,"text/html"), but how do I do it for a page that is actually a report, meaning it's contents are dynamic. Hope somone can help. Thank you.
Use a templating engine, like Velocity, to dynamically replace variables. Depending on tools and frameworks you already use, there might even be some ready-made helper classes. I know Spring has emailing features with built-in Velocity support.
I just want to automate a web application, where that application parses the HTML page and pulls all the HTML Tags inner text based on some condition like if we have a tag called Span Example has given whose class="spanclass_1"
This is span tag...
which has particular class id. so that app parses and pulls that span into it.
And here the main pain area is, I should not use the developer code to automate that same parsing the HTML.
I want to automate that parsing done correctly, simply by using the parsed data which is shown in UI.
Any help, would be great.
Appreciating your time reading this.
(Note span tag is not shown)
Thanks buddies.
not enough details.
is this html page just a file in local filesystem on it is internet webpage?
do u have access to pages? can u modify it ? if answer yes, that just add javascript to page which will extract data and post to server.
if answer not, than it depends on language u use to programm.
Find good framework to parse html. load page parse it and extract data. Several situation can be there.
Worse scenario - page generated on client side using js.
Best scenario - page is in xhtml mode( u are lucky. any xml parser will help to build dom and extract data)
So so - page is simple html format (try several html parser to find most suitable for u)
