To count how many times a user presses the button, you need to set counter on button click.ExampleFollowing is the code − Live Demo Document Press Me The current Value is= 0 var increment = 0; var current = document.getElementById('incrementThisValue'); document.getElementById('pressButton').onclick = (event) => { current.textContent = ++increment; }; To run the above program, save the file name anyName.html (index.html). Right click on the file and select the option “Open with Live Server” in VS Code editor.OutputThe output is as follows −When you press ... Read More
For this, use jQuery(selector).toolTip().ExampleFollowing is the code: − Live Demo Document Write Your Favourite Subject Name: jQuery(".demoTooltip").toolTip() To run the above program, save the file name anyName.html (index.html). Right click on the file and select the option “Open with Live Server” in VS Code editor.OutputThe output is as follows −When you will hover the mouse inside the text box, you will get your tooltip −Your Favourite Subject may be JavaScript...Displayed in the below screenshot as well −
To toggle content, use slideToggle() in JavaScript.ExampleFollowing is the code: − Live Demo Document .firstDiv { display: none; } .txtBox { display: block; } Press Me to toggle the text box Enter your name: function toogleTheTextBox() { $('#firstDiv').slideToggle(function () { $('#txtBox').focus(); }); } To run the above program, save the file name anyName.html (index.html). Right click on the file and select the option “Open with Live Server” in VS Code editor.OutputThe output is as follows −Press the button “Press Me” to toggle the text box.OutputThe output is as follows −
Let’s say the following are our numbers with object values −var numberObject = { 2:90 , 6: 98 }Use Array.from() in JavaScript −var fillThePositionValue = Array.from({length: 15}, (value, index) => numberObject[index+ 1] || "novalue")ExampleFollowing is the code to loop numbers with object values −var numberObject = { 2:90 , 6: 98 } console.log("The actual object is="); console.log(numberObject); var fillThePositionValue = Array.from({length: 15}, (value, index) => numberObject[index+ 1] || "novalue") console.log("After filling the value, the actual object is="); console.log(fillThePositionValue)To run the above program, you need to use the following command −node fileName.js.Here, my file name is demo215.js.OutputThe output is as follows ...

To implicitly mimic click(), you can call a function internally.ExampleFollowing is the code to implicitly mimic click − Live Demo Document My Name is John Doe demo1Data = document.getElementById('demo1').innerHTML demo1Data = demo1Data.replace('My Name is John Doe', `My Favourite Subject is JavaScript..`) document.getElementById('demo2').innerHTML = demo1Data function replaceData() { document.getElementById('output').innerHTML = 'I live is US.'; } document.getElementById('demo2').querySelector('span').click(); To run the above program, save the file name anyName.html (index.html). Right click on the file and select ... Read More
Set the disabled property to true in jQuery −ExampleFollowing is the code − Live Demo Document $("#change").click(function (buttonEvent) { buttonEvent.preventDefault(); $('#showTxtBoxHide').prop("disabled", false); }); To run the above program, save the file name anyName.html(index.html). Right click on the file and select the option “Open with live server” in VS Code editor −OutputThe output is as follows −The text box property is disabled. To enable, you need to click the button −
To store large numbers in JavaScript, use BigInt() rather than + operator. If you will use the + operator, then expect loss of precision.Let’s say the following is our large number and we are storing using BigInt() −console.log("Loss of precision with + operator..")ExampleFollowing is the code −var stringValue1="100"; console.log("The integer value="); console.log(+stringValue1); var stringValue2="2312123211345545367"; console.log("Loss of precision with + operator..") console.log(+stringValue2); const storeLongInteger=BigInt("2312123211345545367"); console.log("No loss of precision with BigInt()"); console.log(storeLongInteger);To run the above program, you need to use the following command −node fileName.js. Here, my file name is demo212.js.OutputThe output is as follows on console −PS C:\Users\Amit\JavaScript-code> node demo213.js The ... Read More
In this problem, we are given a number N. Our task is to create a Program to find N-th term of series 0, 2, 1, 3, 1, 5, 2, 7, 3...in C++.Problem Description − We are given the Series −0, 2, 1, 3, 1, 5, 2, 7, 3...N TermTo find the Nth term of this series, we will formula the general term of the series and then find the Nth term.Let’s take an example to understand the problem, Input − N = 7Output − 2Solution Approach :To solve the problem and find the general formula for the series. We need ... Read More
In this problem, we are given a number N. Our task is to create a Program to find N-th term of series 0, 9, 22, 39, 60, 85, 114, 147, …in C++.Problem Description − We are given the Series −0, 9, 22, 39, 60, 85, 114, 147, ....NtermsTo find the Nth term of this series, we will formula the general term of the series and then find the Nth term.Let’s take an example to understand the problem, Input − N = 6Output − 85Solution Approach:To find the general term of the series.

In this problem, we are given a number N. Our task is to create a Program to find N-th term of series 1, 3, 12, 60, 360...in C++.Given Series1, 3, 12, 60, 360, 2520 … N TermsLet’s take an example to understand the problem, Input − N = 6Output − 2520Solution Approach:The general term formula for this one is a bit tricky. So, the increase in the series values is huge. So, there can be a few possibilities factorial or exponentials. So, we will first consider factorial, and on observing we can see the growth half as half of the ... Read More
