Vue realizes sliding puzzle verification code?

In order to realize the sliding puzzle verification code, we can use Vue.js and some JavaScript libraries to manipulate DOM elements and handle user interaction.

Here are the simple implementation steps of sliding puzzle verification code:

Create an HTML structure: Create an HTML structure with a background picture, a blank picture and a slider, and set their styles and positions using CSS styles.

Monitor events of slider dragging: use the event monitoring function of Vue.js to monitor events of user dragging and releasing the slider, and calculate the offset according to the position of the slider.

Verify the user input: When the user releases the slider, calculate the offset between the slider and the background picture and compare it with the pre-stored correct value. If it matches, the verification is passed; Otherwise, prompt the user to try again.

Reset the verification code: after each verification, reset the verification code to allow the next verification.

In order to realize the verification code of the sliding puzzle, some JavaScript libraries, such as dragdealer.js or other draggable libraries, are needed to realize the dragging effect of the slider, and crypto.js or other encryption libraries are needed to generate and verify the verification code value.

In a word, using Vue.js to realize the sliding puzzle verification code needs to combine various technologies and libraries, and it needs to carefully analyze and select the appropriate tools and methods to complete the implementation.
