在JADE中进行循环

Question

I am busy learning the templating language JADE, and I can't seem to figure out how to do for loops.

Currently I have the following code:

- for (var i = 0; i < 10; ++i) {
p #{var}
- }

I'm trying to output the value of var in a p tag ten times.

Answer 1

The word var is a keyword in Javascript. Jade is written in Javascript. There is no variable, var , the definition to create variables is

var [NameOfMyVariable] = [TheDataIntoMyVariable];

This being so, what you intend is to obtain an iteration of a variable. which in this case is i ,

- for (var i = 0; i < 10; ++i) {
  p #{i}
- }

Answer 2

you should use the jade syntax to loop over an array: http://jade-lang.com/reference/iteration/

for instance:

ul each val in [1, 2, 3, 4, 5] li= val

and as Alejo already said, you cannot use var as a variable in jade, because it's a JavaScript keyword.
