What is the dojo/dom-prop class?

Dojo is a JavaScript toolkit (library) that provides many utility modules and functions to create a web application. We can save time and speed up the development process using the predefined Dojo modules. Dojo includes language utilities, UI components, and more.

The dojo/dom-prop class

The dojo/dom-prop module is a utility module to get and set the properties of the DOM node. It has two methods get and set.

In the above code:

• Line 6: We have created a div element with id as parent.

• Line 7: We load the dojo library from the CDN server.

• Line 9: We load the dojo/dom-prop module that contains the get and set method.

• Line 11: We use the get method of the dom-prop to get the innerHTML property of the element with id parent . We will get the innerHTML property as return value.

set method

Explanation

In the above code:

• Line 6: We have created a div element with id as parent.

• Line 7: We load the dojo library from the CDN server.

• Line 9: We load the dojo/dom-prop module that contains the get and set method.

• Line 15: We use the set method of the dom-prop to set the class property of the element with the id parent . This will set the class property of the parent element as new-class-1.

• Line 20: We use the set method of the dom-prop to set the properties(class and innetHTML) of the element with the id parent . Here we pass the properties as an object. This will change the class property to new-class-2 and the innerHTML property as new content.
