To print content of JavaScript object, you can try to run the following code. Here, the object is created using the new keyword −ExampleLive Demo var dept = new Object(); dept.employee = "Amit"; dept.department = "Technical"; dept.technology ="C++"; document.getElementById("test").innerHTML = dept.employee + " is working on " + dept.technology + " technology.";
A graph is given; we have to check the given graph is a star graph or not.By traversing the graph, we have to find the number of vertices has degree one, and number of vertices, whose degree is n-1. (Here n is the number of vertices in the given graph). When the number of vertices with degree 1 is n-1 and a number of vertices with a degree (n-1) is one, then it is a star graph.Input and OutputInput: The adjacency matrix: 0 1 1 1 1 0 0 0 1 0 0 0 1 0 0 0 Output: ...

Bellman-Ford algorithm is used to find minimum distance from the source vertex to any other vertex. The main difference between this algorithm with Dijkstra’s the algorithm is, in Dijkstra’s algorithm we cannot handle the negative weight, but here we can handle it easily.Bellman-Ford algorithm finds the distance in a bottom-up manner. At first, it finds those distances which have only one edge in the path. After that increase the path length to find all possible solutions.Input and OutputInput: The cost matrix of the graph: 0 6 ∞ 7 ∞ ∞ 0 5 8 -4 ∞ -2 0 ∞ ∞ ∞ ... Read More
The new keyword in JavaScript is the new operator, which creates an instance of a user-defined object type.ExampleYou can try to run the following code to create JavaScript objects using new operator −Live Demo var dept = new Object(); dept.employee = "Amit"; dept.department = "Technical"; dept.technology ="Java"; document.getElementById("test").innerHTML = dept.employee + " is working on " + dept.technology + " technology."; OutputAmit is working on Java technology.
To set the width and height of an alert box in JavaScript, you need to use the custom alert box. This alert box is styled with CSS.Set the width and height of the alert box using the following code, which uses jQuery, a JavaScript library −Example function functionAlert(msg, myYes) { var confirmBox = $("#confirm"); confirmBox.find(".message").text(msg); confirmBox.find(".yes").unbind().click(function() ...

To print debug messages in the Google Chrome JavaScript Console, write a script, which is not creating console functions if they do not exist −if (!window.console) console = {}; console.log = console.log || function(){}; console.warn = console.warn || function(){}; console.error = console.error || function(){};Above you can see the following functions are used to log items based on a log, warn or info. It won’t cause errors when the console isn’t available. The following functions work in Google Chrome console −console.log( ); console.warn(); console.error();The Console object is used to access the browser's debugging console. As an example, consider the Web Console ... Read More
In this problem a set of different boxes are given, the length, breadth, and width may differ for different boxes. Our task is to find a stack of these boxes, whose height is as much as possible. We can rotate any box as we wish. But there is a rule to maintain.One can place a box on another box if the area of the top surface for the bottom box is larger than the lower area of the top box.Input and OutputInput: A list of boxes is given. Each box is denoted by (length, bredth, height). { (4, 6, 7), ... Read More
To change the styling of JavaScript alert button, use the custom alert box. You can try to run the following code to change the styling of alert buttons. The button looks different and more fancy −ExampleLive Demo function functionAlert(msg, myYes) { var confirmBox = $("#confirm"); confirmBox.find(".message").text(msg); confirmBox.find(".yes").unbind().click(function() { confirmBox.hide(); }); ...

The official specification of HTML5 states:When the autofill field name is "on", the user agent should attempt to use heuristics to determine the most appropriate values to offer the user, e.g. based on the element's name value, the position of the element in the document's DOM, whaUse any of the following as values for the autocomplete attribute:)Field NameMeaning"name"Full name"honoritic-prefix"Prefix or title (e.g. "Mr.", "Ms.", "Dr.", "M||e")"given-name"Given name (in some Western cultures, also known as first name"additional-name"Additional name (in some Western cultures, also know as middle name, forenames other than the first name)"family-name"Family name (in some Western cultures, also know as ...

Let’s see the conditions one by one − if(‘0’ == false)It follows the following rule −If Type(y) is Boolean, return the result of the comparison x == ToNumber(y)The == does type coercion. This means an explicit type conversion is requested to match the type of the two operands. The left side '0' is converted to a number 0. On comparing the two numbers, and since 0 equals 0, the result is true. In this case, this does not work since it does not implies about the truish/falsy nature of the '0' string, since it got coerced before it was compared.if(0)This checks ... Read More
