[Problem] Javascript returned by link_to_remote cannot be automatically evaluated.
I created a ajax link using link_to_remote helper. I used the
options[:submit] so that I can submit a form using ajax POST method.
This ajax call would render a rjs in which I did some DOM operations
on the current page. The content of the response is just what I
want(some javascript), but it just cannot be evaluated
automatically.The link my link_to_remote generates is:
<a href="#" id="textSearchLink" onclick="new
Ajax.Request(''/searches'',
{asynchronous:true, evalScripts:true}); return false;">Search</a>
I think the "evalScripts:true" should tell the page to automatically
evaluated the returned javascript but the fact is not like that. I''ve
used other link_to_remote before, all of which use ajax GET method.
I''m thinking whether the returned javascript will not be automatically
evaluated if the ajax method is POST.
How can I solve this problem? Thanks a lot.

There''s nothing wrong with that link. What is the javascript/RJS you''re sending to the page?

Re: [Problem] Javascript returned by link_to_remote cannot be automatically evaluated.
try {
Element.replace("textSearchLink", "<a href=\"#\"
onclick=\"new
Ajax.Request(''/searches/54'', {asynchronous:true,
evalScripts:true,
parameters:Form.serialize(''textSearchFieldset'')});
return false;\">Add</a>");
Element.replace("materialPropertySearchLink", "<a
href=\"#\"
onclick=\"new Ajax.Request(''/searches/54'',
{asynchronous:true,
evalScripts:true,
parameters:Form.serialize(''materialPropertySearchFieldset'')});
return false;\">Add</a>");
Element.replace("metalCompositionSearchLink", "<a
href=\"#\"
onclick=\"new Ajax.Request(''/searches/54'',
{asynchronous:true,
evalScripts:true,
parameters:Form.serialize(''metalCompositionSearchFieldset'')});
return false;\">Add</a>");
new Insertion.Bottom("searchCriteriaDiv", "<p>\n <a
href=\"#\"
onclick=\"new Ajax.Request('''', {asynchronous:true,
evalScripts:true});
return false;\">Remove</a>\n
<label>keyword2</label>\n</p>");
} catch (e) { alert(''RJS error:\n\n'' + e.toString());
alert(''Element.replace(\"textSearchLink\", \"<a
href=\\\"#\\\" onclick\\\"new
Ajax.Request(\''/searches/54\'', {asynchronous:true,
evalScripts:true,
parameters:Form.serialize(\''textSearchFieldset\'')});
return false;\\\">Add</a>\");
\nElement.replace(\"materialPropertySearchLink\", \"<a
href=\\\"#\\\"
onclick=\\\"new Ajax.Request(\''/searches/54\'',
{asynchronous:true,
evalScripts:true,
parameters:Form.serialize(\''materialPropertySearchFieldset\'')});
return false;\\\">Add</a>\");
\nElement.replace(\"metalCompositionSearchLink\", \"<a
href=\\\"#\\\"
onclick=\\\"new Ajax.Request(\''/searches/54\'',
{asynchronous:true,
evalScripts:true,
parameters:Form.serialize(\''metalCompositionSearchFieldset\'')});
return false;\\\">Add</a>\");\nnew
Insertion.Bottom(\"searchCriteriaDiv
\", \"<p>\\n <a href=\\\"#\\\"
onclick=\\\"new Ajax.Request(\''\'',
{asynchronous:true, evalScripts:true}); return
false;\\\">Remove</a>\
\n <label>keyword2</label>\\n</p>\");''); throw
e }
For now, I''m using the option[:complete] to evaluate the above script,
so the link should be like:
<%= link_to_remote ''Search'', { :url => searches_path,
:submit =>
''textSearchFieldset'', :complete =>
''eval(request.responseText)'' },
{ :id => ''textSearchLink'' } %>
This does work, but the script should be evaluated automatically other
than using :complete => ''eval(...)''.
