DOm.Rect with Chrome DevTools Protocol? - node.js

What are some specific uses of dom. Rect or what can it be used for?
I want to use this API to select nodes in the DOM...DOM.Rect

It's just a type that is used in the DOM to represent a rectangular region. It's not much used - you can see a list of places it is referenced in Chrome APIs here: https://vanilla.aslushnikov.com/?DOM.Rect. As you can see, it's not much. And you can't use it to select nodes.

Handling SVG elements using Karate UI Automation [duplicate]

This question already has an answer here:
Karate UI button click support
(1 answer)
Closed 2 years ago.
I am quite new to Karate UI automation and I have a front end UI that has a SVG element which when clicked brings a drop down.
When I am writing the UI test for it, I get javascript evaluation error and hence seek some advice/help.
Here are the screenshots of the UI element and its CSS locator clearly seen on the screen
This is how the CSS locator shows up for the SVG element
This uniquely identifies the SVG element(the plus button)
svg[class='svg-inline--fa fa-plus-square fa-w-14 ']
This is the part of code that I have written to click it
And click("svg[class='svg-inline--fa fa-plus-square fa-w-14 ']")
And here is the error I get:
javascript evaluation failed: click("svg[class='svg-inline--fa fa-plus-square fa-w-14 ']"), js eval failed twice:document.querySelector("svg[class='svg-inline--fa fa-plus-square fa-w-14 ']").click(), error: {"type":"object","subtype":"error","className":"TypeError","description":"TypeError: Cannot read property 'click' of null\n at <anonymous>:1:78","objectId":"{\"injectedScriptId\":2,\"id\":3}"}
I tried various things that can uniquely identify the SVG element like using the compelete Xpath and also using the parent class name(though it was already unique with just the class name) but it still did not work. I tried wildcard locators as well but since there is no text/name of the element, it did not work. When the tags are say input or button etc the same way of css locator works but SVG ones did not for me.
tagname[unique_id of the element like key=value pair]
I am wondering if we need to use a different way to identify SVG elements using Karate UI? The same path when used in Selenium worked.
Since this is a UI that requires VPN connection and secure acccess, it may not be possible to provide a minimum code to try and replicate it. But am happy to provide more details if needed.
I have many such SVG elements on my UI and any help in this would be greatly appreciated.
Use selector hub as an extension to chrome, firefox, edge and opera. Ive only used with chrome and it worked fine and allowed me to quickly and easily find svg relative / absolute xpath. This worked no problems in a find and click capacity on numerous svg elements (via karate script)

Try to get some nearby element and work backwards: https://stackoverflow.com/a/63988977/143475
Figure out the location of the SVG and fire a mouse-click: https://stackoverflow.com/a/63828083/143475
Unable to give you specifics without a way to replicate, but - it should be possible to find a "pattern" so you can write a custom function as described in the docs. So that can be your goal, something like this:
* svgClick('svg-inline--fa')

Can I use an SVG image as an button icon?

Is this possible at all? I call Image.createSVG(...) and receive an Image object without any errors. I then call Button.setIcon(). But there's no icon on the button.
You need to check Image.isSVGSupported() which currently will always return false.
Back in the day J2ME supported SVG thru one of the JSR's. No platform since has supported SVG natively with the exception of the web so this doesn't work on any of the modern platforms and we didn't bother implementing this even for the JavaScript port.
In the future we'd like to have a more efficient/portable way of supporting SVG e.g.: https://github.com/codenameone/CodenameOne/issues/1890

Do SVG docs support custom data- attributes?

In HTML5, elements can have arbitrary metadata stored in XML attributes whose names start with data- such as <p data-myid="123456">. Is this part of the SVG spec too?
In practice this technique works fine for SVG docs in many places. But I'd like to know if it's part of the official SVG spec or not, because the format is young enough that there's still a lot of incompatibility between browsers, especially in mobile. So before committing to code I'd like know if I can expect future browsers to converge on supporting this.
I found this message from the working group mailing list saying they "expect [they] will" support it. Did this become official?
While other answers are technically correct, they omit the fact that SVG provides an alternative mechanism for data-*. SVG allows any attribute and tag to be included, as long as it doesn't conflict with existing ones (in other words: you should use namespaces).
To use this (equivalent) mechanism:
use mydata:id instead of data-myid, like this: <p mydata:id="123456">
make sure you define the namespace in SVG opening tag, like this: <svg xmlns:mydata="http://www.myexample.com/whatever">
EDIT: SVG2, currently W3C Candidate Recommendation (04 October 2018), will support data- directly (without namespaces, the same as HTML). It will take some time before the support is widespread though. Thanks #cvrebert for pointing this out.
The data-* attribute is part of HTML5. It’s not a generic XML attribute.
The current SVG W3C Recommendation is SVG 1.1 (from 2011-08). It doesn’t allow this attribute, as you can check in the attributes list.
The same is the case for the SVG 2 Working Draft (from 2012-08). Update (2015): It seems that it’s intended to support data-* attributes in SVG 2 (currently still a Working Draft).
data-* attributes on SVG elements are officially supported in the current draft of SVG2. See:
w3c/svgwg commit 1cb4ee9: Added SVGElement.dataset and allowed data-* attributes on all SVG elements.
ACTION-3694: Add "data-*" attributes notes to spec. (Created on: January 15, 2015)
RESOLUTION: We will reserve "data-*" attributes to be used in SVG content. The API for handling them is on Element. (from SVG WG Telecon on 15-Jan-2015)
https://lists.w3.org/Archives/Public/www-svg/2014Dec/0022.html
there is a more general mechanism.
svg supports desc elements which may contain arbitrary xml from other namespaces. link instances of this elements or child nodes from you own namespace by dependent ids or refid attributes.
this is the relevant part of the spec (5.4).

How to generate and handle dynamic layouts and symbols in JSF/Richfaces?

My objective is to generate a graphic layout (made of Richfaces components) based on some input configuration (like an XML file) and display it in my web app. The layout is composed of graphic symbols representing various entities in the system: each symbol should be mapped to an entity in the system, in order to display its state. The XML configuration file is used to define the symbol connections and positions within the layout, and their mapping rules to an entity. How can I achieve this?
I was thinking to create a symbol library in a technology such as SVG, where you can define both the aspect and the behaviour, and then simply "wrap" each SVG symbol in a dynamically created richfaces component, which would allow me to handle both the user interactions and the mapping rules defined in the symbol. Unfortunately JSF/Richfaces don't support SVG images, therefore I would have to use plain HTML without Richfaces features.
Another way to achieve that would be to simply define generic symbols in the XML file, each one of them with an attribute specifying the related image, the mapping rule, etc., and then generate the corresponding richfaces component from within the web-app. By doing so, would I be able to then display all the symbols in the right position and therefore generate the complete dynamic layout?
Could you suggest a better approach? Thank you very much.
I believe that HTML5 has direct support for SVG images, however it is still an embedded object in regular HTML after all. This too is something I have been waiting for however I don't believe any of the current JSF2 component libraries have an offerring for this yet.
Here is a good explanation of a possible workaround:
Getting started with SVG graphics objects in JSF 2.0 pages
Potentially you could build a custom facelet component utilizing this workaround?
My thought though is that when your only tool is a hammer, everything looks like a nail. I would try to utilize an RIA (Rich Internet Application) technology better suited for display and manipulation of vector graphics like HTML5, Flash+Flex, Silverlight, etc..

Best web technology for building dynamic charts

I need to build a custom designed bar chart that displays some simple data. Below are my requirements. Can anyone suggest the best web technology for my requirements.
high browser compatibility
ability to draw shapes
ability to fill shapes with gradients
ability to have onclick and onmouseover events for the different shapes (bars in the chart).
Thanks guys. I was thinking of using svg but looking for suggestions.
How about Raphaël - it's SVG/VML.
It says:
Browser compatibility:
Raphaël currently supports Firefox
3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
Ability to draw shapes
circle, rect, ellipse, image, text, path
Ability to fill shapes with gradients
yes
Ability to have onclick and onmouseover events
yes:
... every graphical object you
create is also a DOM object, so you
can attach JavaScript event handlers
or modify them later.
Everything in the reference
On top of that, there's a plugin called gRaphael which makes the creation of charts easier.
Simple data - Google Charts API or Google Visualization API may suit you.
Details for all features of image charts can be found on the Chart feature list
You may also take a look at the comparison of the Charts API and the Visualization API.
Another candidate of course is JQuery SVG - if you're already familiar with jquery you may prefer this one.
There's a comparison of JQuery SVG and Raphaël on SO:
jQuery SVG vs. Raphael
I recommend using Adobe Flex. Below is an example of how easy pie chart creation can be in Flex:
<mx:Panel title="Pie Chart">
<mx:PieChart id="myChart"
dataProvider="{expenses}"
showDataTips="true"
>
<mx:series>
<mx:PieSeries
field="Amount"
nameField="Expense"
labelPosition="callout"
/>
</mx:series>
</mx:PieChart>
<mx:Legend dataProvider="{myChart}"/>
Based on your criteria:
high browser compatibility: Flex is used on more than 95% of all browsers and behaves the same in all browsers. No more need to check if your web app is running in ie, firefox, chrome, etc... because any browser that has a flash player is compatible.
ability to draw shapes: Flash's greatest strength is the ability to draw. Charts are completely customizable and skinnable to achieve the look you need.
Ability to fill shapes with gradients - done easily by setting style attributes or a custom skin.
ability to have onclick and onmouseover events for the different shapes - see this link for some easy ways to create user interactions with charts.
Hi i hope this link may help you i found it while searching for a solution similar to what you're looking for:
http://www.artetics.com/Articles/using-various-javascript-libraries-to-create-pie-chart
i'm trying gRaphael, i'm having difficulties on finding documentation though. you have to read the code and use the exploded instead of the min.js
I would like to share jquery.jqplot.js. It has lots of jQuery options, but depends on other plugins such as syntaxhighliter etc.
