Overview The Jquery consists of a predefined method which makes it easy for the developer to build this feature. The Jquery provides a selector Syntax by which we can find any text element. So the ":contains" selector is used for finding the text in any element. To learn fully about this ":contains" selector we will be developing this feature through an Example. Syntax The Syntax for finding the text in an element is given below − $(selector:contains()); selector − The selector in the above Syntax is termed as any element or class or id name which is ...

Overview The extraction of colors from an image means that the colors which are present in an image in the form of pixels will be extracted, and an average of the pixels of the distinct is calculated in the form of RGB (Red Green Blue) and a new average color will be formed on the basis of the average of the color pixels. So we can achieve this with the help of JavaScript, in the JavaScript there is a property "canvas" which is used to draw an image or any content in the form of pixels. Approach To build this ...

Pandas is an open-source Python library used for data analysis and manipulation. Pandas provides functionality for data cleaning, transformation, and filtering. In large datasets, some extreme values called outliers can modify the data analysis result. In order to identify those outliers, a robust statistical measure called the Interquartile range (IQR) is used. In this article, we will understand how pandas filter with the IQR to identify and handle outliers in the dataset. Understanding the Interquartile Range (IQR) Before understanding how to use the Pandas filter with IQR, let’s briefly understand what is Interquartile range(IQR). Quartile divides a dataset into four ... Read More
Overview To get the selected options from a dropbox we will be using the JavaScript library that is Jquery. The Jquery provides the feature to select and find the options in the optimum lines of code. For this we will be using pseudo selector class ":selected" for the single selection and multiple selection. So for this in the single selection we will directly alert the user and in multiple we will be storing the Output in the array then displaying it on the screen. Syntax The Syntax used in this feature is − $("option:selected").text(); option:selected − The ... Read More
Overview Using Jquery we can create this feature, as Jquery library provides the methods for changing the span text to the value of the input value. In this feature we should have a prior knowledge of the basic HTML and the Jquery. So the Jquery provides the methods as next() and text(), these two methods play a vital role in building this feature. We will also use a few styling methods to make the change visible from other normal text. Syntax The Syntax used in this feature is − $(selector).next().text("text"); selector − The selector in the above ... Read More
Overview The disabled elements are the elements which are not usable for the end user. These elements are disabled using the "disable" attribute. So using the JQuery library we can find all the total number of disabled elements in a HTML page. Using the Jquery selector we can find all the disabled elements by passing the ":disabled" pseudo selector. The ":disabled" selector will select all the elements in the top−down approach. This approach will scan all the disabled attributes and will list it out in a variable. Syntax The Syntax used in this approach is − $(":disabled").each(function () { ... Read More
Pandas is a Python library that is used for data manipulation and analysis of structured data. The cut() and qcut() methods of pandas are used for creating categorical variables from numerical data. The cut() and qcut() methods split the numerical data into discrete intervals or quantiles respectively and assign labels to each interval or quantile. In this article, we will understand the functionalities of the cut() and qcut() methods with the help of various examples. The cut() Function The cut() divides a continuous variable into discrete bins or intervals based on specified criteria. It creates groups or categories of ... Read More
Overview Jquery is a library which contains various predefined methods with their specific functionality. So to get all the children elements which contains the specific class with their tags can be achieved with the Jquery children() method. The Jquery children() method takes a single argument as the condition at which the set of data will be returned. As we want to find all the children with the specified class so we will be passing the class name as the argument within the method to find all the specific class. Syntax The Syntax used in this approach is − $(element).children(className); ... Read More
Overview JQuery is a great JavaScript library which contains many pre−built methods which helps us to perform a certain function without writing a number of lines of code. An element in jQuery can be considered as any HTML element which is a parent of another element. So the elements inside an element are also termed as the children of that element and the container in which the children elements resides are the parent element. So to filter out the children of any element using the jQuery can be achieved using the jQuery children() method and the CSS (Cascading Style Sheet) ... Read More
Overview An object in JavaScript is defined as a set of key−value pairs. It is used to define the properties of a single object. So to filter the object depending on the field's value can be achieved using JavaScript. By using the if−else condition we can filter the object depending on the value. So to filter from the object, first we have access to the key from the object, so for this we should have some prior knowledge of the object and its manipulation. As the manipulation of the object plays an important role in filtering the field value of ... Read More
