jQuery.post gets some code but the code isn't evaluated

Rails
1

I’m calling one of my controller actions with this remote call:

jQuery.post("/plans/<%= @plan.id %>/add_learning_objective?name=" +
objective_name)

The action does its stuff and then falls through to a .js.rjs file that
has this code:

page.alert(“in rjs file”)
page.replace_html “learning_objectives”, :partial => “test”

Then, nothing happens. In the firebug console, i can see that the
result of the post call is this:

try {

alert(“in rjs file”);

jQuery("#learning_objectives").html(“NEW STUFF\n”);

} catch (e) { alert(‘RJS error:\n\n’ + e.toString()); alert('alert(“in
rjs file”);\njQuery("#learning_objectives

").html(“NEW STUFF\n”);’); throw e }

But, it looks like this code is being generated but not actually run: if
i run the contents of the try block in the console then it does what
it’s supposed to do. Can anyone explain what’s going on here?

thanks

jQuery.post("/plans/<%= @plan.id %>/add_learning_objective?name=" +
objective_name)

You need to specify the type option as “script” to have it executed.
(See the docs for jQuery.ajax(), where it is the dataType option. The
“type” option in $.post is passed to $.ajax as the dataType option)

Thanks Rein, that was exactly it: using .ajax instead of .post worked
perfectly:

//doesn’t evaluate the response, ie doesn’t run the javascript in my
.js.rjs file
jQuery.post("/plans/<%= @plan.id %>/add_learning_objective?name=" +
objective_name);

//this works
jQuery.ajax({
type: “POST”,
url: ("/plans/<%= @plan.id %>/add_learning_objective?name=" +
objective_name),
dataType: “script”
})

Thanks again
