  • RE : What is a raw type and why shouldn't we use it?
    Asked on July 15, 2020 in Java.

    tutorial page.

    A raw type is the name of a generic class or interface without any type arguments. For example, given the generic Box class: 

    public class Box<T> {     public void set(T t) { /* ... */ }     // ... }

    To create a parameterized type of Box, you supply an actual type argument for the formal type parameter T: 

    Box<Integer> intBox = new Box<>();

    If the actual type argument is omitted, you create a raw type of Box: 

    Box rawBox = new Box();

  • RE : Copy vendor folder via ftp
    Asked on July 15, 2020 in php.

    Simplest solution is to run composer dumpautoload if you have ssh access. That will allow composer to rewrite the auto load files relative to the directory it is in now.

  • RE : How to toggle between two plotly charts with plain html, css, js
    Asked on July 15, 2020 in HTML.

    I am assuming you are able to generate the chart but need functionality to switch between them by pressing a button.

    // your logic to draw both charts //Plotly.plot('chart1', bar_graph, {}); //Plotly.plot('chart2', bar_graph, {});  const toggleBtn = document.querySelector(".btn-toggle-chart"); const charts = document.querySelectorAll(".chart");  toggleBtn.addEventListener("click", (event) => {   charts.forEach(chart => {     chart.classList.toggle("hide");   }) })
    .hide {   display: none !important }
    <section id="page-4" class="page">   <button class="btn btn-link btn-toggle-chart">Toggle Chart</button>    <div class="row chart" id="chart1">     <p>Demo Chart 1</p>   </div>      <!-- hide second chart by default -->   <div class="row chart hide" id="chart2">     <p>Demo Chart 2</p>   </div> </section>

  • RE : Using javascript custom dialog box before deleting a record. But does not know how to send the php value via js
    Asked on July 15, 2020 in Java Script.

    This is VERY BAD PRACTICE <a href='delete.php?id=<?php echo $id; ?>'>Delete</a> – one visit from a spider that ignores your coustom confirm will wipe your database

    So you need to do this:

    <button type="button" class="delete" data-id="<?php echo $id; ?>">Delete</button>

    Then you can do

    let currentLink = "" $('.delete').on('click',function() {   const id  = $(this).data("id");   currentLink = "delete.php?id="+id;   document.body.scrollTop = 0; // For Safari   document.documentElement.scrollTop = 0; // For Chrome, Firefox, IE and Opera   Confirm('Are you sure you want to delete item','This will delete '+id, 'Yes', 'No');  });

    and have

    $('.doAction').click(function() {   $(this).parents('.dialog-ovelay').fadeOut(500, function() {     location.href = currentLink;     $(this).remove(); // does this even execute?   }); });

  • RE : Need javascript to auto-scroll to the target html element after page loads
    Asked on July 15, 2020 in Java Script.

    Also change your body tag to something like

    <body onload="ScrollToTarget">

    Then your function can be defined in the header as

    function ScrollToTarget() {      document.getElementById("target").scrollIntoView(true); }

  • RE : How to change a javascript variable with HTML?
    Asked on July 15, 2020 in Java Script.

    In short: document.getElementById("myRange").value;.

    You can read more about sliders and getting the value of the slider here. If you want to get the value every time the slider is utilised:

    document.getElementById("myRange").addEventListener("input", (evt) => {   console.log(evt.target.value); })

  • RE : Python not throwing errors or exceptions, websocket on_message
    Asked on July 15, 2020 in Python.

    This is due to a failsafe mechanism implemented here. If you’d like to track your exceptions, you should set a proper level to the logger. For that, do:

    import websocket websocket._logging._logger.level = -99 # This will enable all levels of logging  # Rest of your code goes here

    That way, after running your code, you would see:

      File "blablabla/.local/lib/python3.7/site-packages/websocket/_app.py", line 346, in _callback     callback(self, *args)   File "blablabla/test/test.py", line 22, in ws_message     f("hi", True) #<--should throw a too many arguments error/exception

    Your code would still be running, but you would be able to catch exceptions
