var = #{message} in my example I get undefined local variable or method message
- message = 'it works' above :javascript everything works fineI want to run iteration .each inside :javascript. See the last code sample for what I need in final javascript code. Where I need to loop few ruby variables (or one hash of hashes of hashes?) to get this. Data (='basics') can have few elemenets. It can have children with few elements etc.
SO this haml code
%html
%head
:javascript
$(document).ready(function() {
- message = 'it works'
var = message
});
%body
- message2 = 'hi'
= message2
%div{:id =>"jstree"}
gives me this html code
<html>
<head>
<script type='text/javascript'>
//<![CDATA[
$(document).ready(function() {
- message = 'hi'
var = message
});
//]]>
</script>
</head>
<body>
hi
<div id='jstree'></div>
</body>
</html>
The final javascript code I want to produce using haml is the javascript variable
var data = [{
data: "basics",
attr: {},
children: [
{data: "login", attr: {run: "run"},
children: [
{data: "login", attr: {}}
]
} ,
{data: "Academic Year", attr: {run: "run"},
children: [
{data: "login", attr: {}},
{data: "Academic Year", attr: {filter: "mini", SOF: "yes"}}
]
}
]
}];

First, let's review what you seem to know:
- ....#{...} markup to interpolate Ruby code inside a filter.You say you want to run each, but presumably you want output from this; since the result of #{...} is turned into a string and put in your code, what you really want (probably) is map:
%html
%head
:javascript
var foo = [];
#{
limit = rand(4)+3
array = (0..limit).to_a
array.map{ |i| "foo[#{i}] = #{rand(12)};" }.join ' '
}
console.log(foo.length);
%body
Running the above code gives this output:
<html>
<head>
<script type='text/javascript'>
//<![CDATA[
var foo = [];
foo[0] = 2; foo[1] = 0; foo[2] = 11; foo[3] = 8; foo[4] = 0; foo[5] = 1;
//]]>
</script>
<body></body>
</head>
</html>
As you can see, the big #{...} block (which may span multiple lines) runs arbitrary Ruby code. The result of the last expression (in this case the map{...}.join) is converted to a string and placed in the output.

The haml documentation for filters states that you can interpolate Ruby code using #{}
- flavor = "raspberry"
#content
:textile
I *really* prefer _#{h flavor}_ jam.
