The operating environment of this tutorial: Windows 10 system, JavaScript version 1.8.5, Dell G3 computer.
JavaScript plug-in encapsulates the methods and properties of native JavaScript to make it more convenient for developers to use. For example: getting the value of the input box, native JavaScript and jQuery:
var val=docume.getElementById('id').value;//原生JavaScript var val1=$('#id').val();//jQuery方法
It can be seen from the code that jQuery is more convenient to use, and using plug-ins is to improve the work efficiency of developers. JavaScript plug-ins still need to be learned, especially jQuery, which is very powerful. There are many plug-ins that rely on jQuery. The benefits of using native JavaScript allow developers to better understand the language and nature of JavaScript. It is recommended that while learning to use JavaScript plug-ins, you should not give up learning and using native JavaScript.
