This question already has an answer here:




  • Javascript to detect when a user saves the web page?

    4 answers




Just like there's window.onbeforeprint to determine if the user is trying to print, is there a similar web API to define a callback when the user is about to save current page to disk (File/ Save as)?



The use case would be the same: being able to make changes to the page before it gets saved.






javascript dom-events

          According to the official mdn docs, there is not.



          There is only one method when "saving for mobile" (aka: adding the icon to the home page) called onbeforeinstallprompt, but I don't think this is what you're looking for.

          • I could be wrong with this review of your post. Many reviewers will check it to find consensus it and if I am wrong I will be punished (with temporal ban) :) IMHO answer on SO should be a "small interesting story" and content direct answer, all other could be a comment.

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...

          Calculate evaluation metrics using cross_val_predict sklearn

          Image
          1 In the sklearn.model_selection.cross_val_predict page it is stated: Generate cross-validated estimates for each input data point. It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean? If this gives estimate of Y (y prediction) for every Y (true Y), why can't I calculate metrics such as RMSE or coefficient of determination using these results? python scikit-learn cross-validation share | improve this question edited Nov 28 '18 at 17:52 desertnaut 20.3k 7 43 79 ...
