The general steps for requesting JSON data using AJAX are as follows:<\/p>\n

    \n
  1. Use the $.ajax function<\/li>\n
  2. Specify the request method and URL. Normally, use the GET method to fetch JSON data, where the URL is the address of the server-side resource containing the JSON data.<\/li>\n
  3. Set the request header to indicate that the content type is JSON.<\/li>\n
  4. when the state changes<\/li>\n
  5. xhr.on ready state change is equal to a function that…<\/li>\n
  6. The value of xhr.readyState is equal to 4.<\/li>\n
  7. The value of xhr.status is equal to 200.<\/li>\n
  8. Submit the request.<\/li>\n<\/ol>\n

    Here is an example code using native AJAX to request JSON data:<\/p>\n

    var<\/span> xhr = new<\/span> XMLHttpRequest<\/span>();\r\nxhr.open<\/span>('GET'<\/span>, 'data.json'<\/span>, true<\/span>);\r\nxhr.setRequestHeader<\/span>('Content-Type'<\/span>, 'application\/json'<\/span>);\r\nxhr.onreadystatechange<\/span> = function<\/span>(<\/span>) {\r\n  if<\/span> (xhr.readyState<\/span> === 4<\/span> && xhr.status<\/span> === 200<\/span>) {\r\n    var<\/span> data = JSON<\/span>.parse<\/span>(xhr.responseText<\/span>);\r\n    \/\/ \u5728\u8fd9\u91cc\u5904\u7406\u54cd\u5e94\u7684JSON\u6570\u636e<\/span>\r\n  }\r\n};\r\nxhr.send<\/span>();\r\n<\/code><\/pre>\n
    In the above code, the request method and URL are set by calling xhr.open method. Next, the request header is set using xhr.setRequestHeader method. Then, a callback function to handle the JSON response data is set using xhr.onreadystatechange. Finally, the request is sent by calling xhr.send() method.<\/p>\n
    Please note that the URL in the example above is a relative path with respect to the current page. You can replace it with the actual URL you are using.<\/p>\n","protected":false},"excerpt":{"rendered":"
