Detailed explanation of applications based on template engine Jade

In this article, the editor will share with you a detailed explanation of the application based on the template engine Jade. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to take a look, I hope it can help everyone.

Useful symbols:

| The characters after the vertical bar will be output as is. The dot indicates that all characters at the next level will be output as they are and will no longer be recognized. . (It is an upgraded version of |, enabling batch implementation) include means referencing external files

The dash indicates that the character following is just a piece of code (the difference from | is that the content after | will be displayed, and the character after the dash The content is not displayed directly! )

Example:

js：

##

const jade = require('jade');
console.log(jade.renderFile('./xxx.jade',{pretty:true,name:'singsingasong'}))

'|'Application

'.'Application

Application of include

# Application of class

##p

'-'

Direct reference to variables

span#{a} has the same effect as span=a.

for loop in jade

jade:

-for(var i=0;i<arr.length;i++)
 p=arr[i]

js file:

console.log(jade.renderFile('./views/11.jade',{pretty:true,name:'singsingasong',
 arr:['aaa','bbb','ccc','ddd']
}));

Running result:

'!' Application

html
 head
 body
 p(class='1')!=content
 p(class='2')

Running results:

jade’s if...else...

html
 head
 body
 -var a=19;
 if(a%2==0)
  p(style={background:'red'}) 偶数
 else
  p(style={background:'green'}) 奇数

case statement

html

 -var a=1;
 case a
  when 0
  p aaa

Here is a comprehensive tip:

We did not write DOCTYPE in the previous jade file, so add # to it here.

##The execution result is: if the file is read and written successfully, 'success' will be output, if an error occurs, 'error' will be returned. Related recommendations:
