The ng-mousedown Directive in AngularJS basically specifies a custom event on mouse-down event. We can perform multiple functions whenever the mouse is pressed and the mouse-down event is called.Syntax..content..Example − ngMousedown DirectiveCreate a file "ngMousedown.html" in your Angular project directory and copy-paste the following code snippet. ngMousedown Directive Welcome to Tutorials Point angularjs | ngMousedown Directive Click mouse and hold !!! OutputTo run the above code, just go to your file and run it as a normal HTML file.Your browser does not support HTML5 video.
The ng-app Directive in AngularJS is used for auto-bootstraping of an AngularJS application. This directive gives the root element of the application and is generally placed near the root element of the page like on the or tags. This directive declares the root context from where the application will be started.Points to note while using the ngApp Directive −Only one application can be bootstrapped per the HTML element. If you declare multiple ngApp components, the first ngApp appearing element will be considered as the root element for auto-bootstrap. For running multiple applications in the HTML, one should use the ... Read More
The angular.element() method wraps the raw DOM element or the HTML string as a jQuery element. If jQuery is available or imported, angular.element is an alias for the jQuery function, else this method delegates to AngularJS’s built-in subset of jQuery called jQueryLite or jqLite.Syntaxangular.element(element)Example − Wrapping the DOM element using angular.element()Create a file "element.html" in your Angular project directory and copy-paste the following code snippet. angular.element() Welcome to Tutorials Point ...

Tkinter creates a default window with its default size while initializing the application. We can customize the geometry of the window using the geometry method.However, in order to maximize the window, we can use the state() method which can be used for scaling the tkinter window. It maximizes the window after passing the “zoomed” state value to it.Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("600x400") #Create a text label Label(win, text="It takes only 21 days to create a new Habit", font=('Times New Roman ...

Tkinter initially creates a window that contains application components such as widgets and control bars. We can switch a native-looking application to a full-screen application by using the attribute(‘-fullscreen’, True) method. To make the window full-screen, just invoke the method with the particular window.Example# Import tkinter library from tkinter import * # Create an instance of tkinter frame or window win = Tk() # Set the geometry of tkinter frame win.geometry("750x250") # Create a Text widget text= Label(win, text=" HelloWelcome to Tutorialspoint.com!", font=('Century Schoolbook', 20, 'italic bold')) text.pack(pady=30) win.attributes('-fullscreen', True) win.mainloop()OutputExecuting the above code will ...

The ng-copy Directive in AngularJS is used for specifying any custom behaviour while copying the texts in input text fields. We can use this directive to call certain methods that will be triggered while the text is copied from the input field. This directive is supported by all types of input elements.Syntax..content..Example − ngCopy DirectiveCreate a file "ngCopy.html" in your Angular project directory and copy-paste the following code snippet. ngCopy Directive .index {color: white; background-color: green;} ...

To plot a plane using some mathematical equation in matplotlib, we can take the following steps.StepsSet the figure size and adjust the padding between and around the subplots.Create x and y data points using numpy.Using x and y, find the equation of the plane (eq).Create a new figure or activate an existing figure.Get the current axis with projection='3d'.Create a surface plot with x, y and eq data points.To display the figure, use Show() method.Exampleimport numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-10, 10, 100) y = np.linspace(-10, 10, 100) ...

The equals() method in AngularJS basically checks if two objects or two values are equal or not. This method supports value types, regular expressions, arrays, and objects. It will return True if the reference objects passed inside the function are equal, else it will return False.Syntaxangular.equals(value1, value2)Example − Check if the reference objects are equal or notCreate a file "equals.html" in your Angular project directory and copy-paste the following code snippet. angular.equals() Welcome to Tutorials Points ...
