QUESTION

Javascript code only works in Chrome while Chrome Developer Tools are open

Asked 2020-Nov-02 at 11:04

I have a weird bug that only lets my Javascript code run properly if the Chrome developer tools is open. I have read all the other articles with different solutions including removing all console.log() statements and disabling caching for jQuery AJAX (I am not using jQuery) but they do not work.

When it boils down, I have a navigation bar, a video container, 9 pictures, then I have a canvas that I wish to draw on. The code is supposed to work on the canvas to allow drawing, but only works with chrome developer tools open.

The peculiar thing is if I remove 6 pictures such that I have only have 2 pictures remaining above the canvas, the canvas can be drawn upon without opening developer tools.

I don't think it is an issue of "being drawn but just not appearing on the screen" since I have the correct offsets for the drawings to appear, and even if I didn't, it should not work even if I have developer tools open.

Here is the simplified html file:

You have incorrect calculations for xy, which goes beyond canvas.

If your canvas is located down in the page with the scroll

canvas.offsetTop would be amount the space from the start of the scroll (grows to infinity when your scroll grows), but e.clientY would grow to window height (display height) which is a fix number.

I would suggest using mouseEvent.offsetX which is supported in ie9+ and test it in different conditions on different browsers. I tested it in Chrome and it works perfect w/ and w/o scroll.

QUESTION

Difference between using Jquery to add button, and explicitly adding it in HTML when calling functions

Asked 2020-Oct-10 at 17:40

I am a beginner in HTML/Javascript and know basically no Jquery. I was playing around with npm packages, Jquery, and function calls when I stumbled across a problem.

If I add a button using Jquery and attach an on click function with it, I am able to alert the user of something once the button is clicked.

If I add another button using HTML, I am not able to alert the user of the same thing once the button is clicked.

I have tried two methods of calling the alert() function when adding buttons with HTML, both with no successes while the Jquery button adding works perfectly fine.

Why is this the case? And how do I make the HTML explicitly defined buttons work with function calls?

You have to wait for the content to be rendered before attaching the onclick callback (I'd suggest you use addEventListener('click' instead)

How to import external JavaScript library

Asked 2020-Sep-10 at 21:12

This will be my second HTML/CSS and Javascript project so I am very much a beginner. I am trying to allow the user to draw some shapes/lines on a canvas, and then use an external library called curve-matcher to compare a predetermined shape with the user-drawn shape.

I began with creating a canvas where the user can draw, in an HTML file named index.html . I have 1 button that clears the canvas, and another button that will call the external function and then display the similarity score. This works fine, with code below.

Just add above your existing script tag

Now all the methods in help.js will be available. This isn't generally recommended and you should read about es6 exports and the module pattern.
