This means that it is possible to update parts of a web page, without reloading the whole page.(异步刷新网页，不用整个网页渲染) AJAX applications might use XML to transport data, but it is equally common to transport data as plain text or JSON text. 现在主流用 JSON 1.2 The XMLHttpRequest Object1.2.1 创建 | Chrome, Firefox, IE7+, Edge, Safari, Opera1var myRequest = new XMLHttpRequest(); 1.2.2 XMLHttpRequest Object Methods Method Description open(method, url, async, user, psw) Specifies the request method: the request type GET or POST url: the file location async: true (asynchronous) or false (synchronous) user: optional user name psw: optional password send() Sends the request to the server Used for GET requests send(string) Sends the request to the server. Used for POST requests true : 异步 execute other scripts while waiting for server response deal with the response after the response is ready 使用 onreadystatechange 事件（called every time the readyState changes）触发处理函数 false ： 同步 其他模块会被block直到当前响应完成 无需使用 onreadystatechange 事件，直接编写处理函数 Synchronous XMLHttpRequest (async = false) is not recommended because the JavaScript will stop executing until the server response is ready. If the server is busy or slow, the application will hang or stop. 1.2.3 XMLHttpRequest Object Properties Property Description onreadystatechange Defines a function to be called when the readyState property changes readyState Holds the status of the XMLHttpRequest. 0: request not initialized 1: server connection established 2: request received 3: processing request 4: request finished and response is ready responseText Returns the response data as a string responseXML Returns the response data as XML data status Returns the status-number of a request 200: “OK” 403: “Forbidden” 404: “Not Found” For a complete list go to the Http Messages Reference statusText Returns the status-text (e.g. “OK” or “Not Found”) 1.2.4 编码模板12345if( myRequset.readyState === 4)&#123;

This means that it is possible to update parts of a web page, without reloading the whole page.(异步刷新网页，不用整个网页渲染) AJAX applications might use XML to transport data, but it is equally common to transport data as plain text or JSON text. 现在主流用 JSON 1.2 The XMLHttpRequest Object1.2.1 创建 | Chrome, Firefox, IE7+, Edge, Safari, Opera1var myRequest = new XMLHttpRequest(); 1.2.2 XMLHttpRequest Object Methods Method Description open(method, url, async, user, psw) Specifies the request method: the request type GET or POST url: the file location async: true (asynchronous) or false (synchronous) user: optional user name psw: optional password send() Sends the request to the server Used for GET requests send(string) Sends the request to the server. Used for POST requests true : 异步 execute other scripts while waiting for server response deal with the response after the response is ready 使用 onreadystatechange 事件（called every time the readyState changes）触发处理函数 false ： 同步 其他模块会被block直到当前响应完成 无需使用 onreadystatechange 事件，直接编写处理函数 Synchronous XMLHttpRequest (async = false) is not recommended because the JavaScript will stop executing until the server response is ready. If the server is busy or slow, the application will hang or stop. 1.2.3 XMLHttpRequest Object Properties Property Description onreadystatechange Defines a function to be called when the readyState property changes readyState Holds the status of the XMLHttpRequest. 0: request not initialized 1: server connection established 2: request received 3: processing request 4: request finished and response is ready responseText Returns the response data as a string responseXML Returns the response data as XML data status Returns the status-number of a request 200: “OK” 403: “Forbidden” 404: “Not Found” For a complete list go to the Http Messages Reference statusText Returns the status-text (e.g. “OK” or “Not Found”) 1.2.4 编码模板12345if( myRequset.readyState === 4)&#123;
