I am new to Rails and I have a pretty simple problem with calling javascript functions from within a view. In Rails 2 I would do...
= javascript_tag "name(arguments)"
where the javascript function "name" was located in my application.js file. However, this does not appear to work in Rails 3? Or am I missing something? I have been searching Google for some time without finding an answer.
UPDATE:
OK, so I looked at the source of the two different ways (using the javascript_tag and the haml javascript filter) as suggested. And this is very strange because the html source appears to be identical? Apart from a difference in double and single quotes in declaring the script type.
FIRST: using the javascript_tag which does not work
= javascript_tag "number_interval(#{fact.current_value}, #{fact.growth_per_second}, #{fact.decimal_number}, '#{dom_id(fact, "number")}'"
Source...
<div id='number_number_interval_727'>loading</div>
<script type="text/javascript">
//<![CDATA[
number_interval(6952596670.36814, 2.33002440293917, 0, 'number_number_interval_727'
//]]>
</script>
SECOND: using the haml javascript filter and it works
:javascript
number_interval(#{fact.current_value}, #{fact.growth_per_second}, #{fact.decimal_number}, '#{dom_id(fact, "number")}')
Source...
<div id='number_number_interval_727'>loading</div>
<script type='text/javascript'>
//<![CDATA[
number_interval(6952596917.02179, 2.33002440293917, 0, 'number_number_interval_727')
//]]>
</script>
Well, I guess I'll just stick with the haml filter!
You have a syntax error:
= javascript_tag "number_interval(#{fact.current_value}, #{fact.growth_per_second}, #{fact.decimal_number}, '#{dom_id(fact, "number")}'"
is missing the closing parenthesis for the number_interval
function. I think that it should be:
= javascript_tag "number_interval(#{fact.current_value}, #{fact.growth_per_second}, #{fact.decimal_number}, '#{dom_id(fact, "number")}')"
