I'm trying to use jQuery, and everything has been great, until now, when I'm trying to render a partial and append it to a div. Here is how I have it set up:
I have an action that responds to js:
def index
@objects = Object.find(:all)
respond_to do |format|
format.js
end
end
And a template called index.js.erb with some javascript in it:
alert("hello world");
Firebug returns a "text/javascript" response containing:
alert("hello world");
But the alert window does not appear, nor does any other JavaScript work. I checked out http://railscasts.com/episodes/136-jquery And am more or less following along. I tried several other things, like using .rjs instead of .erb and putting this in my template:
page.alert("hello world");
but I get the same exact result, and the browser never executes the JS.
Anyone know why the JavaScript isn't being executed?
I'm running Rails 2.3.4.
You have to call it from your view or it will never be executed.
an example controller:
def index
@objects = Object.find(:all)
respond_to do |format|
format.js{
render :text => "alert('hello')"
}
end
end
and an index.html.erb with:
<script type="text/javascript">
$(function(){
$.ajax({ url: '/controller', type: 'get', dataType:'script' });
});
</script>
replace '/controller' with the actual url that executes that controller's index action, by default for PostsController it will be '/posts' and so on...
if you like rjs you delete the {} and everithing in it in the controller and create an index.js.erb or index.rjs with:
page.alert("hello world")
or:
page << "hello world"
