Disable the drag and drop image in React

In this tutorial, we are going to learn about how to disable the drag and drop image in React with the help of the examples.

Consider, that we have the image in our React app:

import React from "react"; function App  return ( div> img src="https://via.placeholder.com/150" /> /div> ); > export default App;

To disable the drag and drop image in React, add the onDragStart event to the image element and call the event.preventDefault() method inside it.

The event.preventDefault() method prevents the browser from default actions, so it disables the image from drag and drop.

import React from "react"; function App  return ( div> img src="https://via.placeholder.com/150" onDragStart=(event)=> event.preventDefault()> /> /div> ); > export default App;

Similarly, we can disable the drag and drop image by setting an HTML draggable attribute to false .

import React from "react"; function App  return ( div> img src="https://via.placeholder.com/150" draggable="false" /> /div> ); > export default App;

The draggable attribute can accept the following values:

Disable Drag and Drop image using CSS

We can also disable the drag and drop image by setting the css pointer-events property to none .

When we set a pointer-events property to a value «none» , the element doesn’t respond to any cursor or touch events.

import React from "react"; function App  return ( div> img src="https://via.placeholder.com/150" /> /div> ); > export default App;

As websites become more interactive and user-friendly, it’s important to provide users with the best experience possible. However, there are certain cases where disabling drag and drop functionality can improve usability and prevent potential issues. In this article, we will discuss the best practices and code examples for disabling drag and drop functionality in HTML and CSS.

Using the draggable attribute to disable dragging

The draggable attribute is a simple way to disable dragging of images or HTML elements on a webpage. The attribute can have two values: true or false. When set to false, the element cannot be dragged.

Here is an example of using draggable=»false” in HTML:

This code will prevent the image from being dragged. It’s important to note that the draggable attribute does not work on all elements, such as input fields.

When using the draggable attribute, it’s important to follow these best practices:

• Use the attribute only on elements that are not necessary to be dragged.
• Avoid using the attribute on interactive elements such as buttons and links.
• Consider accessibility implications when disabling dragging.

Disabling dragging using ondragstart attribute in JavaScript

The ondragstart attribute is another way to disable dragging using JavaScript. This attribute is used to specify the function to be executed when an element is dragged.

Here is an example of using ondragstart to disable dragging:

This code will prevent the image from being dragged. It’s important to note that the ondragstart attribute works only on elements that are draggable.

When using ondragstart, it’s important to follow these best practices:

• Use the attribute only on elements that are draggable.
• Avoid using the attribute on interactive elements such as buttons and links.
• Consider accessibility implications when disabling dragging.

Using CSS to disable dragging of images or HTML elements

CSS properties user-drag and user-select can be used to disable dragging of images or HTML elements. The user-drag property is used to specify whether an element is draggable or not.

Here is an example of using user-drag and user-select to disable dragging:

This code will prevent the image from being dragged. It’s important to note that the user-drag property works only on elements that are draggable.

When using CSS to disable dragging, it’s important to follow these best practices:

• Use the properties only on elements that are not necessary to be dragged.
• Avoid using the properties on interactive elements such as buttons and links.
• Consider accessibility implications when disabling dragging.

Using pointer-events property to disable drag and drop functionality

The pointer-events property in CSS can be used to disable drag and drop functionality. This property specifies whether an element should be the target of pointer events.

Here is an example of using pointer-events to disable drag and drop:

This code will prevent the image from being the target of pointer events, including dragging. It’s important to note that the pointer-events property works on all elements.

When using pointer-events to disable drag and drop, it’s important to follow these best practices:

• Use the property only on elements that are not necessary to be dragged.
• Avoid using the property on interactive elements such as buttons and links.
• Consider accessibility implications when disabling drag and drop.

Using HTML Drag and Drop API to enable or disable drag and drop functionality

The html drag and drop api can be used to enable or disable drag and drop functionality. This API provides methods for handling drag and drop events and can be used to customize the behavior of drag and drop.

Here is an example of using the API to disable drag and drop functionality:

document.addEventListener("dragstart", function(event) < event.preventDefault(); >); 

This code will prevent any element from being dragged. It’s important to note that the html drag and drop API works on all elements.

When using the HTML drag and drop api , it’s important to follow these best practices:

• Use the API only when customization of drag and drop behavior is necessary.
• Avoid using the API on interactive elements such as buttons and links.
• Consider accessibility implications when enabling or disabling drag and drop.

Disabling dragging of ghost image in CSS

When an element is dragged, a ghost image is created to represent the dragged element. The -webkit-user-drag CSS property can be used to disable dragging of the ghost image.

Here is an example of using -webkit-user-drag to prevent ghost image dragging:

This code will prevent the ghost image from being dragged. It’s important to note that the -webkit-user-drag property works only on WebKit browsers.

When using -webkit-user-drag, it’s important to follow these best practices:

• Use the property only when necessary.
• Avoid using the property on interactive elements such as buttons and links.
• Consider accessibility implications when disabling dragging of the ghost image.

Disabling drag and drop functionality in Windows using Registry Editor

In some cases, it may be necessary to disable drag and drop functionality in Windows. This can be done using Registry Editor by modifying the DragHeight and DragWidth keys.

Here is an example of disabling drag and drop functionality using Registry Editor:

1. Open Registry Editor by pressing Windows + R and typing “regedit”.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop.
3. Modify the DragHeight and DragWidth keys to 0.
4. Restart Windows.

When using Registry Editor, it’s important to follow these best practices:

• Use Registry Editor only when necessary.
• Make sure to backup the registry before making any changes.
• Consider potential issues and implications when modifying the registry.

Запрет drag and drop css

The following 3 CSS properties:

1. The user-select attribute can set whether to allow the user to select the graphic content on the page;
2. The user-modify attribute can set whether to allow input in the input box and whether to allow only plain text.For details, see the article «How to make contenteditable elements only able to enter plain text»;
3. The user-drag attribute can set whether to allow page elements to be dragged.

The protagonist to be introduced in this article is the last user-drag attribute.

2.user-drag prohibits dragging

If the graphic element on the page is set to -webkit-user-drag:none, the element cannot be dragged.

We use the following case to understand the corresponding effect.

There are two pictures, one is the default UI style, and the other is the CSS code that prohibits dragging.The relevant HTML and CSS codes are as follows:

As a result, when the default image is dragged, you will see a semi-transparent image flying out, like this:

When you click and drag an image that is forbidden to drag and drop, there is no effect:

compatibility

Firefox browser does not support, Chrome browser does not support -webkit-user-drag: element statement, mobile terminal cannot be used, as shown in the screenshot below:

3.HTML draggable attribute

The advantage of using CSS to set elements can be dragged and dropped is that it is easy to control and suitable for desktop PC web products that only need to be compatible with Chrome and Safari browsers.

If HTML has operation permissions, and the final effect requires better compatibility, you still need to use the traditional draggable attribute to achieve, and the element can be dragged by setting true or false.

The effect of dragging is similar to this:

The draggable attribute is often used in conjunction with the native drag & drop event to achieve the drag effect of any element.

The compatibility of the HTML draggable attribute is quite good.It is supported on all mobile terminals and also supported by IE10+ browsers.Basically, HTML attributes that can be used with confidence in this era:
