第9天response 响应渲染 —动态渲染实例
首先,我们建立一个views目录,用来储存动态模板文件,里面建立两个文件index.html和about.html
动态渲染实例
首先,我们建立一个views目录,用来储存动态模板文件,里面建立两个文件index.html
和about.html
index.html
<!doctype html> <html> <head> <title><%=locals.title%></title> </head> <body> hello:<%=locals.name%> </body> </html>
bookabout.html
book
<!doctype html> <html> <head> <title>locals.title</title> </head> <body> <p>About me:</p> <table border=1> <% locals.info.forEach(function(r){%> <tr> <td><%=r[0]%></td> <td><%=r[1]%></td> </tr> <% }) %> </table> </body> </html>
run.js
运行文件
var fk = require("../..") ,App = fk.App ,download = fk.download ,app = new App ,view = fk.view ,fs = require("fs"); app.use(view(__dirname+"/views")); app.get("/",function(req,res){ res.view("index.html",{title:"index page",name:"leo"}); }) app.get("/about",function(req,res){ var info = [ ["Name","Leo"], ["Tel","213442322"], ["Card","322232"] ] res.view('about.html',{title:"about me info",info:info}); }) app.listen(3000);
当启动 node run 后,在浏览器中输入 http://localhost:3000 会显示index.html模板+数据的页面。下面是浏览器显示的html源代码:
<!doctype html> <html> <head> <title>index page</title> </head> <body> hello:leo </body> </html>
当输入 http://localhost:3000/about 时,浏览器页面的html源代码如下:
<!doctype html> <html> <head> <title>locals.title</title> </head> <body> <p>About me:</p> <table border=1> <tr> <td>Name</td> <td>Leo</td> </tr> <tr> <td>Tel</td> <td>213442322</td> </tr> <tr> <td>Card</td> <td>322232</td> </tr> </table> </body> </html>
通过这个实例,我们知道了动态模板渲染的重要性,想象一下如果web框架没有这个功能,那还能用它做什么呢。明天是stuwebfk框架开发的最后一天,让stuwebfk具有session会话特性。
