In this tutorial, we learn to use JavaScript to redirect a webpage after 5 seconds. To redirect a webpage after 5 seconds, use the setInterval() method to set the time interval. Add the webpage in window.location.href object. As we know, whenever we need to call a function or some block of code after a specific delay of time we use the setTimeout() and the setInterval() methods of JavaScript. Lts look at the use of these methods to redirect a web page by 5 seconds. To redirect a page we will use the document.location.href or window.location.href object of JavaScript as shown ...

This operator is just like the >>operator, except that the bits shifted in on the left are always zero i.e. xeroes are filled in from the left.ExampleYou can try to run the following code to learn how to work with unsigned right shift operator −                    var a =-14;          var b =2; // Shift right two bits          document.write("(a >>> b) => ");          result =(a >>> b);          document.write(result);          

Double equals (==) is abstract equality comparison operator, which transforms the operands to the same type before making the comparison. For example,4    ==  4        // true '4'  ==  4        //true 4    == '4'       // true 0    == false     // trueTriple equals (===) are strict equality comparison operator, which returns false for different types and different content.For example,4 === 4  // true 4 === '4' // false var v1 = {'value':'key'}; var v2 = {'value': 'key'}; v1 === v2 //false

In this tutorial, we learn to use JavaScript to load a webpage after 5 seconds. We use the setTimeout() function in JavaScript to load a webpage after some interval. This function waits for some seconds and then loads the web page. We could also apply the setInterval() method to perform our task. Generally, a web page loads immediately if the network connection to which user connected is very strong, and if the network connection is very poor, then it will take some time to load. But did you know that, we can stop the web page loading for some time ... Read More

We use a URL in the anchor tags or buttons to navigate the user to another location. We must verify the URL's validity before using it. URL Rule URL must start with http:// or https://. ...

In this tutorial, we will learn to load a JavaScript function using the name of a variable. Functions are the block of statements that takes an input and displays the result to the user after an execution. We can use these blocks of codes repeatedly by only declaring the function, and these functions can help a programmer in many ways as it also reduces efforts. JavaScript also supports the use of functions like other programming languages. Functions in JavaScript can be either built-in or user-defined. There are different ways to declare a function and call it. Generally, a simple Function ... Read More
