Ajax Receiving Background Data and Displaying It on HTML Page

Java code

 PrintWriter out=response.getWriter(); //Send character data to the client
 response.setContentType("text/text"); //Set the content type and encoding method of the request and response
 response.setCharacterEncoding("UTF-8");
 JSONArray json = JSONArray.fromObject(newsList); //Convert the newsList object to a json object
 String str = json.toString(); //Convert the json object to a string
 out.write(str); //Transfer the str character to the front-end 

　

Ajax code

 $(document).ready(function() {
 $.ajax({
 url : "newsservlet",//Request address
 dataType : "json",//Data format 
 type : "post",//Request method
 async : false,//Is the request asynchronous
 success : function(data) { //How to send successfully
 var html = "";
 for(var i=0;i<data.length;i++{ //Traverse the data array
 var ls = data[i]; 
 html +="<li><a href='second page text.html#63;newsid="+ls.news_id+"'class='infNews_word_a'><span>"+ls.news_name+"</span></a><span class='date'>"+ls.news_time+"</span></li>";
 }
 $("#ulul").html(html); //Display HTML content in the tag with id ulul in the html page
 },
>)
>)

HTML page

<ul id="ulul"></ul>

In AJAX, "#" represents the id of a tag, and "." represents the class of a tag.

In the Java background, setting the content type and encoding method of the request and response must be written before the json object is converted to a string, otherwise it will cause乱码 in json Chinese.
