set password as a variable while typing












-1















Trying to avoid any browser's stuff about autocomplete, password suggestion etc.



And at the same time keep the show/hide letters functionality.



The idea is to keep password as a variable, regardless of show/hide state.



In the code below problem is if user press Backspace or Delete key. In that case the whole concept crushes down.



Any help?






var pass = "";



$('#inpass').on('input', function(){

	if(!$('#checka').is(':checked')){

		let a = $(this).val();

		let b = a.substr(-1);

		pass += b;

		let c = a.replace(/.$/, '*');

		$(this).val(c);

		console.log(pass);

	}

});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>



<input type='text' id='inpass' maxlength='25' placeholder='password' title='password' autocomplete='off'>

<br><br>

<input type='checkbox' id='checka'>

<label for='checka' id='labela'>show letters</label>

    The whole concept also fails if the user uses arrow keys to change a previous character, not just the last one.

    If it works, it is a real solution. As your question currently stands it is too broad. As have been mentioned in the comments, there are multiple issues with your code.

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
