There is a function that returns getBoundingClientRect of HTML element:

I am using windows 10, python 3.6

I am running a selenium project my code is

I need some help to apply js code for all elements, but for now works only for first on each page.

On page are items with buy buttons, that is created by script, so all buttons have same id but is more than one of them - and I can't apply script that disable button if some condition, only work for first button.

There is list of list of tuples:

I am selecting vertices from a point cloud using angular and three.js. I have been trying to label a selected vertex with its x,y,z information. I have been using these resources in my attempt:

1. three.js Vector3 to 2D screen coordinate with rotated scene
2. https://threejsfundamentals.org/threejs/lessons/threejs-align-html-elements-to-3d.html

and I can't get either to work as described.

My code currently is:

In other words, I would like to port this simple C++ program to Perl 5:

I would like to have a page split in two columns, one of which should overlay over the other one. I haven't been able to do this, so I ask you guys for help. Please ignore the messy svg code, it was copied from inkscape because I wanted to have some clickable elements inside it.

The first/left column (test column) only appears if there is a list to iterate, otherwise it's hidden. The problem with the flexbox solution I have used in the script below is that the second column is offset when the first column appears. I would like it to just appear "above" the page in the area around the black square, without moving any other elements. How would I be able to achieve that?

I try to divide an xml output from nmap into arrays. The nmap script scans the ssh ciphers of a port and the goal of my python script is to filter the nmap output into insecure ciphers. The xml output looks like this:

I am trying to set up a form in which buttons fill input fields and in which those input fields can again be emptied by other "delete" buttons.

This works quite well, but I cannot get rid of one problem in a special action sequence:

If I press buttons "one" and "three", the corresponding input forms are filled properly, this is what I want.

Now if after that I press the "Delete A" button, one of two unwanted things happen:

• If the command event.preventDefault() exists in line 15, then (only) the first input field gets cleared correctly and the buttons are restored. But when I then again press button "one", the complete form gets cleared and the word "three" vanishes from form 2.

• If the command event.preventDefault() is deleted from line 15, then as soon as I press "Delete A", the complete form gets cleared and also the word "three" vanishes from form 2.

I do not want to clear the complete form to be reloaded at any stage.

EDIT: The problem is not a question of returning false values from functions to prevent form submission as discussed in JavaScript code to stop form submission . in fact all my fucntions are returning falsevalues.
