In Vue.js, how can I get a keypress event to get the latest version of the input?












1














In the following code:



https://codepen.io/anon/pen/WYJopq



I monitor key presses and try to clone the input into another input as follows:



  [![methods: {

    clone: function() {

      this.mirror = this.original;

    }

  }]


But the cloned input is always one keystroke behind:

How do I update my code so that the cloned input exactly matches the original input?



(Note: I know for this simple example, there's an idiomatic Vue.js way to do things, but I'm specifically interested in doing this via keystroke monitoring)

    Have you tried using keyup instead of keypress?

With a keyboard, we have three events fired in the following order:





  1. keydown - fired before character inserted


  2. keypress - fired when a character is getting inserted


  3. keyup - fired when character is already inserted


In this scenario, if you need input with updated characters, you should use keyup event which is after the character is inserted into the input.



Having said this, you should probably use @input event as relying on the keyboard means you are not thinking about other ways via which text can be inserted into the input box. For example, copy-paste or using an on-screen keyboard:



<input type="text" v-model="original" @input="clone()" />

            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{...
