Comparative study on get and post request methods in jQuery

In front-end development, using jQuery to make network requests is a very common operation. In jQuery, the two commonly used network request methods are get and post. This article will deeply study the characteristics, advantages and disadvantages of these two request methods, and compare them through specific code examples.

  • The request speed is fast and can be cached.

Code sample

$.get("data.json", function(data) {
    console.log("成功加载数据:" + data);
});

2. post request method
