artTemplate的常见用法。
需要先使用一个type="text/html"的script标签存放模板
1.简单的json数据
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="js/template.js" ></script>
</head>
<body>
<div id="container"></div>
<script type="text/html" id="div">
<h1>{{name}}</h1>
<h2>{{age}}</h2>
</script>
<script type="text/javascript">
var data = {
name:"geekWeb",
age:22
}
var html = template('div',data);
document.getElementById("container").innerHTML = html;
</script>
</body>
</html>
2.带数组的json数据
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="js/template.js" ></script>
</head>
<body>
<div id="container"></div>
<script type="text/html" id="div">
<h1>{{name}}</h1>
<ul>
{{each lang as value i}}
<li>语言{{i+1}}:{{value}}</li>
{{/each}}
</ul>
</script>
<script type="text/javascript">
var data = {
name:"前端语言",
lang:['html','css','js']
}
var html = template('div',data);
document.getElementById("container").innerHTML = html;
</script>
</body>
</html>
3.数组中包含对象的json数据
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="js/template.js" ></script>
</head>
<body>
<div id="container"></div>
<script type="text/html" id="div">
<h1>{{name}}</h1>
<ul>
{{each lang}}
<li>语言:{{$value.title}} 定义:{{$value.add}}</li>
{{/each}}
</ul>
</script>
<script type="text/javascript">
var data = {
name:"前端语言",
lang:[{
title:"html",
add:"超文本标记语言"
},{
title:"css",
add:"层叠样式表"
},{
title:"javaScript",
add:"添加动态特效"
}]
}
var html = template('div',data);
document.getElementById("container").innerHTML = html;
</script>
</body>
</html>
一个ajax+artTemplate+servlet+fastjson的综合小实例
前台：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>$Title$</title>
<script src="template.js"></script>
<script>
//创建一个XMLHttpRequest类型的对象ajaxReq
var ajaxReq = new XMLHttpRequest();
window.onload = function() {
//用ajaxReq打开一个连接
ajaxReq.open("get","ajax.do",true);
//发送请求给服务器
ajaxReq.send(null);
//设置一个回调函数，用来处理服务器的回应。
ajaxReq.onreadystatechange = onReceive;
}
function onReceive() {
if (ajaxReq.readyState === 4) {
if (ajaxReq.status === 200) {
//响应成功,做一些事情
var jsonObj = JSON.parse(ajaxReq.responseText);//不要忘记将json字符串转化为json对象
var html = template('test', jsonObj);
document.getElementById('content').innerHTML = html;
} else {
//响应失败,做一些事情
}
}
};
</script>
</head>
<body>
<div id="content"></div>
<script id="test" type="text/html">
<table>
<thead>
<td>姓名</td>
<td>年龄</td>
</thead>
{{each list as value i}}
<tr>
<td>{{value.name}}</td>
<td>{{value.age}}</td>
</tr>
{{/each}}
</table>
</script>
</body>
</html>
后台：
public class Person {
public String name;
public int age;
}
public class Persons {
private List<Person> list;
public List<Person> getList() {
return list;
}
public void setList(List<Person> list) {
this.list = list;
}
}
import com.alibaba.fastjson.JSON;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;
/**

*/
@WebServlet(name = "Servlet",urlPatterns = "/ajax.do")
public class Servlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Person person = new Person();
person.name = "huochai";
person.age = 29;
String strJson = JSON.toJSONString(person);
System.out.println(strJson);
Person person2 = new Person();
person2.name = "huochai2";
person2.age = 292;
List<Person> lst = new ArrayList<Person>();
lst.add(person);
lst.add(person2);
Persons persons = new Persons();
persons.setList(lst);
String strJson2 = JSON.toJSONString(persons);
System.out.println(strJson2);
PrintWriter pw = response.getWriter();
pw.println(strJson2);
}
}
