To transfer JSON data format using AJAX, follow these steps:<\/p>\n

    \n
  1. Instantiate an XMLHttpRequest object:<\/li>\n<\/ol>\n
    var xhttp = new XMLHttpRequest();\r\n<\/code><\/pre>\n
      \n
    1. Create a callback function to handle the server’s response.<\/li>\n<\/ol>\n
      xhttp.onreadystatechange = function() {\r\n  if (this.readyState == 4 && this.status == 200) {\r\n    \/\/ \u5904\u7406\u670d\u52a1\u5668\u7684\u54cd\u5e94\r\n  }\r\n};\r\n<\/code><\/pre>\n
        \n
      1. Open a connection to the server, specifying the method, URL, and whether it should be asynchronous.<\/li>\n<\/ol>\n
        xhttp.open(\"POST\", \"http:\/\/example.com\/api\", true);\r\n<\/code><\/pre>\n
          \n
        1. Set the request header to specify the data format as JSON.<\/li>\n<\/ol>\n
          xhttp.setRequestHeader(\"Content-Type\", \"application\/json\");\r\n<\/code><\/pre>\n
            \n
          1. Convert the data to a JSON string and send it to the server.<\/li>\n<\/ol>\n
            var data = { \"name\": \"John\", \"age\": 30 };\r\nxhttp.send(JSON.stringify(data));\r\n<\/code><\/pre>\n
            On the server side, you can use relevant programming languages (such as Java, Python, etc.) to parse the received JSON data.<\/p>\n","protected":false},"excerpt":{"rendered":"
