Question

I’m trying to use Coffeescrip/jQuery to iterate through every span on a page and return the text enclosed between a particular span’s tags if the id of that span is equal to the variable elemId. Here’s what I have:

elemValue = $('span').each ->
  $(@).text() if $(@).attr("id") is elemId

For some reason, though, this only returns [object Object] for the elemValue that I output to the page, even when I test it on a page that I know has a span with that elemId. Any idea where I’m going wrong?

Also, how to set a default value for elemValue, in case there is no span on the page has an id that is the same as elemId?

Answer 1

if you know the id then why are you iterating whole span. just use id to get text

 $("#" +elemId ).text()
