Block or Disable Cut, Copy and Paste operation Using jQuery

It is required to block the cut, copy and paste operations on some of the textbox. For example, it will be better if we do not allow users to copy paste the data entered in Email and Confirm Email field in order to make the user to type themselves.

The below jQuery code will help us to do the same using preventDefault() method

Move List Items Up and Down Using jQuery

Sometimes, we require moving/scrolling the list items in the select control up and down to sort manually. This little code snippet will help us to do that using jQuery library.

var nextOption = $("#ListBox1 > option[selected]").next("option");

if ($(nextOption).text() != "") {
      $(selectedOption).remove();

$(nextOption).after($(selectedOption));
    }
  }

function MoveUp() {
    var selectedOption = $("#ListBox1 > option[selected]");

var prevOption = $("#ListBox1 > option[selected]").prev("option");

if ($(prevOption).text() != "") {
      $(selectedOption).remove();

$(prevOption).before($(selectedOption));
    }
  }
</script>

8 Must Know JavaScript Array Methods

Working with arrays in JavaScript used to be a pain with barely any support for complex array operations. Fast forward to today, though, and there are tons of amazing JavaScript array methods available to us. In this video I will be covering the 8 most important array methods in JavaScript.

const items =[
{ name: 'Bike', price:100},
{ name: 'TV', price:200},
{ name: 'Album', price:10},
{ name: 'Book', price:5},
{ name: 'Phone', price:500},
{ name: 'Computer', price:1000},
{ name: 'Keyboard', price:25}
]

// create another array with filtered items
const filteredItems = items.filter((item) => {
return item.price <= 100
})

console.log(filteredItems);

// get element and create another array
const itemNames = items.map((item) => {
return item.name
});

console.log(itemNames)

//find element in array
const foundItem = items.find((item) =>{
return item.name === 'Album'
})
console.log(foundItem)

//forEach
items.forEach((item) =>{
console.log(item.price)
})

// some -- return true if found
const hasInExpensiveItem = items.some((item) =>{
return item.price <= 100
})
console.log(hasInExpensiveItem)

// calculate with variable initiate as 0
const total = items.reduce((currentTotal, item){
return item.price + currentTotal
},0) // 0 is the initial value of CurrentTotal

console.log(total)

// include -- if item present in array return true.. this work fine with simple array...

const items =[1, 2, 3, 4, 5]
const includesTwo = items.includes(2)
console.log (includesTwo) // return True..

const includesTwo = items.includes(6)
console.log (includesTwo) // return false..

// distinct from array

var distinct = (value, index, self) =>{
return self.indexOf(value) === index;
}

var years = [2016, 2017, 2017, 2020, 2016, 2019]
var distinctYears = years.filter(distinct)

output : [2016, 2017, 2020, 2019]
