Mouse event[X and Y coordinates]

I'm new to electron and somehow my JS script is not working in electron.
Here is my Javascript .I would like to implement this code in electron by making it a desktop application. Kindly help me. Whenever I tried starting it using electron I can't seem to have the results like in a web browser.



Here I provide the JS script and the HTML.






var numbers = ;

var Globaldistance;

$(function() {

  var x1,y1,x2,y2;	

  var drawlines ;

  var theCanvas = document.getElementById('paint');

  var ctx = theCanvas.getContext('2d');

  var img = document.getElementById("trya");	

  theCanvas.width = 500;

  theCanvas.height = 500;



  var canvasOffset = $('#paint').offset();

  $('#paint').mousemove(function(e) {

    if (drawlines) {

      ctx.clearRect(0,0,theCanvas.width,theCanvas.height);

      ctx.strokeStyle = 'red';

      ctx.lineWidth = 1;

      ctx.beginPath();

    

      ctx.moveTo(drawlines.x, drawlines.y);

      ctx.lineTo(e.pageX - canvasOffset.left, e.pageY - canvasOffset.top);

      ctx.stroke();	

	  	

	  document.getElementById("hehe").innerHTML= "Page X2: "+e.pageX;

	  document.getElementById("haha").innerHTML= "Page Y2: "+e.pageY;

	  x2 = e.pageX;	

	  y2 = e.pageY;	

		

    }   numbers.push(x1,y1);

 	    numbers.push(x2,y2);

	  document.getElementById("tra").innerHTML= "Coordinates in x1 y1 x2 y2 respectively	: "+numbers[0]+" "+numbers[1]+" "+numbers[2]+" "+numbers[3];	

	  compute(numbers[0],numbers[1],numbers[2],numbers[3]);

  });



  $('#paint').mousedown(function(e) {

  });

          Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

          Image
          28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

          Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

          Image
          up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

          A Topological Invariant for $pi_3(U(n))$

          Image
          3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
