Backbone.js remove View
Backbone.js is a compact library used to organize JavaScript code. An MVC/MV* framework is another term for it. If MVC is unfamiliar to you, it simply refers to a technique for designing user interfaces. The creation of a program’s user interface is made considerably easier by JavaScript functions. BackboneJS provides a variety of building elements to aid developers in creating client-side web applications, including models, views, events, routers, and collections.
View’s Remove method is mainly used to delete a view from the DOM. When this function is triggered it in return triggers the stopListening function which stops the view to call the events which the view earlier listenTo’d.
Syntax:
view.remove()
Example 1: The code below demonstrates how to Remove a view by clicking on a button and triggering the remove method.
HTML
<!DOCTYPE html> <html> <head> <title>Backbone.js remove View</title> <script src= type="text/javascript"> </script> <script src= type="text/javascript"> </script> <script src= type="text/javascript"> </script> </head> <body> <h1 style="color: green;"> zambiatek </h1> <h3>Backbone.js remove View</h3> <div id="mydiv"></div> <script type="text/javascript"> var ViewDemo = Backbone.View.extend({ events: { 'click input': 'removeFunc' }, removeFunc: function () { myView.remove(); document.write("The View has been removed.") }, render: function () { this.$el.html( '<input type="button" value="Click to remove this view"></input>'); }, initialize: function () { this.render(); } }); var myView = new ViewDemo({ el: '#mydiv' }); </script> </body> </html> |

Example 2: The code below demonstrates how you can trigger the remove method of a View from another view.
