QUESTION

Azure Maps how to disable keyboard shortcuts?

Asked 2021-Nov-03 at 22:34

This really niggled me for ages before i realized that pressing the delete or backspace keyboard button whilst a feature/shape (in my case a 'Point') is selected in edit mode by the drawing manager then it would actually delete it. I can't allow this to happen otherwise each time i press the backspace button when editing a text label then it ends up deleting it!

As you'll see in the image above, i have designed a custom edit control form where once a feature/shape (in my case a 'Point') is selected then the user can edit the Title text input and the title will dynamically update. But as soon as they press the backspace button on their keyboard, the map thinks I want to delete it.

I need to be able to disable the keybaord shortcuts for delete, if i wanted to delete the feature then I'd select the delete button instead (button with the bin icon) grrr this is so annoying, cant find anything in MS docs that explains how to disable this keyboard shortcut?

Right so I've come up with a small hack, not ideal but it works nicely!

I add a few functions, one for the mouseover event and one for mouseout. Add these events to the text input and fire then accordingly i.e. if the user is going to modify the text in the input field then the mouseover event is active and we can therefore put the drawing manage into 'idle' state. Putting the drawing manager into idle state stops the undesired keyboard shortcuts from functionning.

Then finally once the mouse cursor leaves the text input then we can restore the drawing manager back into edit mode.

HTML code for the text input ('Title: input as shown in the screenshot from my original question):

This happens because of two things:

Inside your draw() function you're setting the starting point and the end point with every call. Usually you determine the start as soon as the user pushes the mousebutton - once.
even with #1 fixed, the line end might still look a bit 'fuzzy'. This can be fixed by setting the context's lineCap style to round instead of it's default butt - which squares of line endpoints.

Here's an example based on your code (just click 'Run code snippet'):

QUESTION

HTML5 Color Input Won't Open

Asked 2020-Nov-02 at 23:28

I'm working on a web application that involves using canvases as a shared whiteboard between people. I have an HTML5 color input on a menu that becomes visible when hovering over the whiteboard so that the user can change the color of the drawing tool.

My issue is that during testing, the color picker won't open the majority of the time. I have two tabs open both with instances of the whiteboard to test. The color picker will only open on the first instance of the page I have open.

On the second page, when I click on the color picker it refuses to open. It shows the click animation on the button but the browser's color picker dialog doesn't open. Also, if I refresh the first instance of the page, the color picker stops working there as well. The only way I can get it to work again is if I completely close both tabs and reopen one.

I've tried and confirmed that this happens in both Chrome and Firefox which makes me think it's an issue with the HTML. This is a snippet of HTML that surrounds the color picker.

I wrote the HTML intending to make the popup menu show up relative to the anchor button. But, the input element being inside of the anchor is causing the issue. After the first load, clicking the color input triggers the anchor instead of bringing up the color window.

I don't know why the color picker works on the first load but I'm fairly sure this is what is causing the issue. I did some research and found that you aren't supposed to put buttons inside of anchors and this is basically that.

I moved the color input out of the anchor and it worked perfectly.

It's frustrating that there isn't any documentation about this issue or errors thrown by the browser.
