I have a project that is to involve opening several image files onto the same place on the screen to overlay or not overlay them. I know nothing about java script, but someone gave me a sample script that sort of does what I'm trying to do. In that script the files are all located on the web and it references the html links for them. I'd like to be easily shareable and not really have to rely on the images being hosted somewhere. I thought I could include the image files and along with the script all in one folder so they't all be installed in the same place. I tried the full path to that pla ..read more

Dear all, I'm currently dealing with unit tests using Jasmine/KarmaRunner.

I'v learned so far, how I can check the count, arguments and order of calls from the tested method, which I expect. But what if someone inserts a new line into the tested method, that is unknown in the test und does "strange other things"... Is there something like "Jasmine.allCalls( object, 'method')...? Thx in advance and best regards! Please stay objective and friendly ..read more

I wrote a function, where one can update an invoice. So the user clicks edit, the modal pops up, they change the price, and the function calls an API, updates the database, and processes the returned data. Then it calls a function within, that changes the invoice price on the page, and creates a mutation observer to detect the price change, and tallies up the invoice cost, and changes the total at the bottom. The purpose of this mutation observer, is to wait for the DOM to update the cost, and when the DOM signals it's been done, then go back to the DOM and tally up the cost, and change the ..read more
