I have prepared online order form for a printing house. In the form everything works smoothly. But I need to put total amount of each order into shopping cart, because someone may want to order several print jobs. I am new in javascript, I tried to do it by the loop, but it adds only once. Any help will be appreciated.

I'm learning Go and I have some problem.

Actually i'm having some issues in my app,

Like i have a button that open front camera and skan a waiter badge but the problem comes when i try to check if a device has the camera and if it hasn't i just hide that buttons.

But i have a device that use the front camera as QR Scanner so it's not really a camera that can be used so the app crash when i try to click that button.

So the question is how can i handle and check if not only the camera exists but even if it works?

I'm trying to figure out why this bit of code isn't working. I'm looping through a dependency tree (deepObject), and for each one I want to run a function which returns a promise. I would then like for the next set of functions to happen after the resolution of all the promises, but the console logs inside the promise.all are not executing. ES6 is cool too, if you have a better approach, however I would also really like to know why this code is not working.

I have an application whereby a user can contact me by filling out a form and in the form the user just has to fill in his details and his email and subject.

The code throws no error but I could not receive the mail after setting up everything, but the contact details gets stored in the database as I want it to be stored.

Below is my code.

I use xyplot() from the Lattice to plot arrows defined by a dataframe with 3 columns: posi (numerical), from (character), to (character). The problem: On occasion, the arrows go beyond the scale of the plot. In other words, the plot window is not big enough to visualize all the data.

I tried adding the factor levels explicitly, to no avail. It seems that if the more extreme levels (e.g. "D") are not present in the factor "df$from", those are not counted to draw the plot window. I looked at ylim but this is limited to numerical values.

I have looked around on SO, and found a lot concerning rescaling, reordering axes but nothing that helped me with the problem at hand. This question is related to a question from @skan: How to plot segments or arrows in Lattice.
