How to run the same function on different sections on a page with same class name

I have function that is calculating the difference between two fields and showing it in the third field. This is working fine. How can I run the same function if I have multiple "mysection" in my html to calculate the difference between fields within each of these sections?

$(document).ready(function(){
    var total=$(".field2");
    total.keyup(function(){
	var diff = Number($(".field2").val()) - Number($(".field1").val());	
   $(".field3").val(diff.toFixed(2));
    });	
	});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="mysection">
	<input type="text" name="field1" value="" size="30" maxlength="300" class="field1">
	<input type="text" name="field2" value="" size="30" maxlength="300" class="field2">
	<input type="text" name="field3" value="" size="30" maxlength="300" class="field3">
	</div>

You can use siblings & $(this). Also delegate the event from the parent that is div.mysection.

In this case on key up event $(this).val() will get the value for input with field2 element & $(this).siblings(‘.field1’).val() will get the value from the sibling element with this class

$(document).ready(function() {
  $('.mysection').on('keyup', '.field2', function() {
    var field2Val = $(this).val();
    let getFieldOne = $(this).siblings('.field1').val();
    var diff = Number(field2Val) - Number(getFieldOne);
    $(this).siblings(".field3").val(diff.toFixed(2));
  })
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="mysection">
  <input type="text" name="field1" value="" size="30" maxlength="300" class="field1">
  <input type="text" name="field2" value="" size="30" maxlength="300" class="field2">
  <input type="text" name="field3" value="" size="30" maxlength="300" class="field3">
</div>

<div class="mysection">
  <input type="text" name="field1" value="" size="30" maxlength="300" class="field1">
  <input type="text" name="field2" value="" size="30" maxlength="300" class="field2">
  <input type="text" name="field3" value="" size="30" maxlength="300" class="field3">
</div>

The Difference Between Regular Functions and Arrow Functions in JavaScript

Other then the syntactical differences. The main difference is the way the this keyword behaves? In an arrow function, the this keyword remains the same throughout the life-cycle of the function and is always bound to the value of this in the closest non-arrow parent function. Arrow functions can never be constructor functions so they can never be invoked with the new keyword. And they can never have duplicate named parameters like a regular function not using strict mode.

Here are a few code examples to show you some of the differences
this.name = "Bob";

const person = {
name: “Jon”,

<span style="color: #008000">// Regular function</span>
func1: <span style="color: #0000ff">function</span> () {
    console.log(<span style="color: #0000ff">this</span>);
},

<span style="color: #008000">// Arrow function</span>
func2: () =&gt; {
    console.log(<span style="color: #0000ff">this</span>);
}

}

person.func1(); // Call the Regular function
// Output: {name:“Jon”, func1:[Function: func1], func2:[Function: func2]}

person.func2(); // Call the Arrow function
// Output: {name:“Bob”}

The new keyword with an arrow function
const person = (name) => console.log("Your name is " + name);
const bob = new person("Bob");
// Uncaught TypeError: person is not a constructor

If you want to see a visual presentation on the differences, then you can see the video below:

Activation Functions, Optimization Techniques, and Loss Functions

Activation Functions:

A significant piece of a neural system Activation function is numerical conditions that decide the yield of a neural system. The capacity is joined to every neuron in the system and decides if it ought to be initiated (“fired”) or not, founded on whether every neuron’s info is applicable for the model’s expectation. Initiation works likewise help standardize the yield of every neuron to a range somewhere in the range of 1 and 0 or between — 1 and 1.

Progressively, neural systems use linear and non-linear activation functions, which can enable the system to learn complex information, figure and adapt practically any capacity speaking to an inquiry, and give precise forecasts.

Linear Activation Functions:

**Step-Up: **Activation functions are dynamic units of neural systems. They figure the net yield of a neural node. In this, Heaviside step work is one of the most widely recognized initiation work in neural systems. The capacity produces paired yield. That is the motivation behind why it is additionally called paired advanced capacity.

The capacity produces 1 (or valid) when info passes edge limit though it produces 0 (or bogus) when information doesn’t pass edge. That is the reason, they are extremely valuable for paired order studies. Every rationale capacity can be actualized by neural systems. In this way, step work is usually utilized in crude neural systems without concealed layer or generally referred to name as single-layer perceptions.

How to Find All the Classes of a Package in Java

In this article let’s take a look at how to find all classes of a package in Java

To find all classes of a package in Java we can use the ClassHunter of Burningwave Core library. So we start by adding the following dependency to our pom.xml:

XML

1

<dependency>2
    <groupId>org.burningwave</groupId>3
    <artifactId>core</artifactId>4
    <version>8.4.0</version>5
</dependency>

The next steps are the following:

  • retrieving the ClassHunter through the ComponentContainer
  • defining a regular expression that we must pass to the **ClassCriteria **object that will be injected into the **SearchConfig **object
  • calling the **loadInCache **method that loads in the cache all loadable classes of the indicated paths, then applies the criteria filter and then returns the **SearchResult **object which contains the classes that match the criteria
