||||
end |
||||
|

# Returns a button input tag with the element name of +name+ and a value (i.e., display text) of +value+ |
||||
# that will submit form using XMLHttpRequest in the background instead of a regular POST request that |
||||
# reloads the page. |
||||
# |
||||
# # Create a button that submits to the create action |
||||
# # |
||||
# # Generates: <input name="create_btn" onclick="new Ajax.Request('/testing/create', |
||||
# # {asynchronous:true, evalScripts:true, parameters:Form.serialize(this.form)}); |
||||
# # return false;" type="button" value="Create" /> |

# Returns a link to a remote action defined by <tt>options[:url]</tt> |
||||
# (using the url_for format) that's called in the background using |
||||
# XMLHttpRequest. The result of that request can then be inserted into a |
||||
# DOM object whose id can be specified with <tt>options[:update]</tt>. |
||||
# Usually, the result would be a partial prepared by the controller with |
||||
# render :partial. |
||||
# |
||||
# Examples: |
||||
# # Generates: <a href="#" onclick="new Ajax.Updater('posts', '/blog/destroy/3', {asynchronous:true, evalScripts:true}); |
||||
# # return false;">Delete this post</a> |
||||
# link_to_remote "Delete this post", :update => "posts", |
||||
# :url => { :action => "destroy", :id => post.id } |
||||
# |
||||
# # Generates: <a href="#" onclick="new Ajax.Updater('emails', '/mail/list_emails', {asynchronous:true, evalScripts:true}); |
||||
# # return false;"><img alt="Refresh" src="/images/refresh.png?" /></a> |
||||
# link_to_remote(image_tag("refresh"), :update => "emails", |
||||
# :url => { :action => "list_emails" }) |
||||
# |
||||
# You can override the generated HTML options by specifying a hash in |
||||
# <tt>options[:html]</tt>. |
||||
# |
||||
# link_to_remote "Delete this post", :update => "posts", |
||||
# :url => post_url(@post), :method => :delete, |
||||
# :html => { :class => "destructive" } |
||||
# |
||||
# You can also specify a hash for <tt>options[:update]</tt> to allow for |
||||
# easy redirection of output to an other DOM element if a server-side |
||||
# error occurs: |
||||
# |
||||
# Example: |
||||
# # Generates: <a href="#" onclick="new Ajax.Updater({success:'posts',failure:'error'}, '/blog/destroy/5', |
||||
# # {asynchronous:true, evalScripts:true}); return false;">Delete this post</a> |
||||
# link_to_remote "Delete this post", |
||||
# :url => { :action => "destroy", :id => post.id }, |
||||
# :update => { :success => "posts", :failure => "error" } |
||||
# |
||||
# Optionally, you can use the <tt>options[:position]</tt> parameter to |
||||
# influence how the target DOM element is updated. It must be one of |
||||
# <tt>:before</tt>, <tt>:top</tt>, <tt>:bottom</tt>, or <tt>:after</tt>. |
||||
# |
||||
# The method used is by default POST. You can also specify GET or you |
||||
# can simulate PUT or DELETE over POST. All specified with <tt>options[:method]</tt> |
||||
# |
||||
# Example: |
||||
# # Generates: <a href="#" onclick="new Ajax.Request('/person/4', {asynchronous:true, evalScripts:true, method:'delete'}); |
||||
# # return false;">Destroy</a> |
||||
# link_to_remote "Destroy", :url => person_url(:id => person), :method => :delete |
||||
# |
||||
# By default, these remote requests are processed asynchronous during |
||||
# which various JavaScript callbacks can be triggered (for progress |
||||
# indicators and the likes). All callbacks get access to the |
||||
# <tt>request</tt> object, which holds the underlying XMLHttpRequest. |
||||
# |
||||
# To access the server response, use <tt>request.responseText</tt>, to |
||||
# find out the HTTP status, use <tt>request.status</tt>. |
||||
# |
||||
# Example: |
||||
# # Generates: <a href="#" onclick="new Ajax.Request('/words/undo?n=33', {asynchronous:true, evalScripts:true, |
||||
# # onComplete:function(request){undoRequestCompleted(request)}}); return false;">hello</a> |
||||
# word = 'hello' |
||||
# link_to_remote word, |
||||
# :url => { :action => "undo", :n => word_counter }, |
||||
# :complete => "undoRequestCompleted(request)" |
||||
# |
||||
# The callbacks that may be specified are (in order): |
||||
# |
||||
# <tt>:loading</tt>:: Called when the remote document is being |
||||
# loaded with data by the browser. |
||||
# <tt>:loaded</tt>:: Called when the browser has finished loading |
||||
# the remote document. |
||||
# <tt>:interactive</tt>:: Called when the user can interact with the |
||||
# remote document, even though it has not |
||||
# finished loading. |
||||
# <tt>:success</tt>:: Called when the XMLHttpRequest is completed, |
||||
# and the HTTP status code is in the 2XX range. |
||||
# <tt>:failure</tt>:: Called when the XMLHttpRequest is completed, |
||||
# and the HTTP status code is not in the 2XX |
||||
# range. |
||||
# <tt>:complete</tt>:: Called when the XMLHttpRequest is complete |
||||
# (fires after success/failure if they are |
||||
# present). |
||||
# |
||||
# You can further refine <tt>:success</tt> and <tt>:failure</tt> by |
||||
# adding additional callbacks for specific status codes. |
||||
# |
||||
# Example: |
||||
# # Generates: <a href="#" onclick="new Ajax.Request('/testing/action', {asynchronous:true, evalScripts:true, |
||||
# # on404:function(request){alert('Not found...? Wrong URL...?')}, |
||||
# # onFailure:function(request){alert('HTTP Error ' + request.status + '!')}}); return false;">hello</a> |
||||
# link_to_remote word, |
||||
# :url => { :action => "action" }, |
||||
# 404 => "alert('Not found...? Wrong URL...?')", |
||||
# :failure => "alert('HTTP Error ' + request.status + '!')" |
||||
# |
||||
# A status code callback overrides the success/failure handlers if |
||||
# present. |
||||
# |
||||
# If you for some reason or another need synchronous processing (that'll |
||||
# block the browser while the request is happening), you can specify |
||||
# <tt>options[:type] = :synchronous</tt>. |
||||
# |
||||
# You can customize further browser side call logic by passing in |
||||
# JavaScript code snippets via some optional parameters. In their order |
||||
# of use these are: |
||||
# |
||||
# <tt>:confirm</tt>:: Adds confirmation dialog. |
||||
# <tt>:condition</tt>:: Perform remote request conditionally |
||||
# by this expression. Use this to |
||||
# describe browser-side conditions when |
||||
# request should not be initiated. |
||||
# <tt>:before</tt>:: Called before request is initiated. |
||||
# <tt>:after</tt>:: Called immediately after request was |
||||
# initiated and before <tt>:loading</tt>. |
||||
# <tt>:submit</tt>:: Specifies the DOM element ID that's used |
||||
# as the parent of the form elements. By |
||||
# default this is the current form, but |
||||
# it could just as well be the ID of a |
||||
# table row or any other DOM element. |
||||
# <tt>:with</tt>:: A JavaScript expression specifying |
||||
# the parameters for the XMLHttpRequest. |
||||
# Any expressions should return a valid |
||||
# URL query string. |
||||
# |
||||
# Example: |
||||
# |
||||
# :with => "'name=' + $('name').value" |
||||
# |
||||
# You can generate a link that uses AJAX in the general case, while |
||||
# degrading gracefully to plain link behavior in the absence of |
||||
# JavaScript by setting <tt>html_options[:href]</tt> to an alternate URL. |
||||
# Note the extra curly braces around the <tt>options</tt> hash separate |
||||
# it as the second parameter from <tt>html_options</tt>, the third. |
||||
# |
||||
# Example: |
||||
# link_to_remote "Delete this post", |
||||
# { :update => "posts", :url => { :action => "destroy", :id => post.id } }, |
||||
# :href => url_for(:action => "destroy", :id => post.id) |
||||
def link_to_remote(name, options = {}, html_options = nil) |
||||
link_to_function(name, remote_function(options), html_options || options.delete(:html)) |
||||
end |
||||
|
||||
# Returns a form tag that will submit using XMLHttpRequest in the |
||||
# background instead of the regular reloading POST arrangement. Even |
||||
# though it's using JavaScript to serialize the form elements, the form |
||||
# submission will work just like a regular submission as viewed by the |
||||
# receiving side (all elements available in <tt>params</tt>). The options for |
||||
# specifying the target with <tt>:url</tt> and defining callbacks is the same as |
||||
# +link_to_remote+. |
||||
# |
||||
# A "fall-through" target for browsers that doesn't do JavaScript can be |
||||
# specified with the <tt>:action</tt>/<tt>:method</tt> options on <tt>:html</tt>. |
||||
# |
||||
# Example: |
||||
# # Generates: |
||||
# # <form action="/some/place" method="post" onsubmit="new Ajax.Request('', |
||||
# # {asynchronous:true, evalScripts:true, parameters:Form.serialize(this)}); return false;"> |
||||
# form_remote_tag :html => { :action => |
||||
# url_for(:controller => "some", :action => "place") } |
||||
# |
||||
# The Hash passed to the <tt>:html</tt> key is equivalent to the options (2nd) |
||||
# argument in the FormTagHelper.form_tag method. |
||||
# |
||||
# By default the fall-through action is the same as the one specified in |
||||
# the <tt>:url</tt> (and the default method is <tt>:post</tt>). |
||||
# |
||||
# form_remote_tag also takes a block, like form_tag: |
||||
# # Generates: |
||||
# # <form action="/" method="post" onsubmit="new Ajax.Request('/', |
||||
# # {asynchronous:true, evalScripts:true, parameters:Form.serialize(this)}); |
||||
# # return false;"> <div><input name="commit" type="submit" value="Save" /></div> |
||||
# # </form> |
||||
# <% form_remote_tag :url => '/posts' do -%> |
||||
# <div><%= submit_tag 'Save' %></div> |
||||
# <% end -%> |

# <% remote_form_for(@post) do |f| %> |

# <% end %> |

# |

# |
||||
# <% remote_form_for :post, @post, :url => post_path(@post), :html => { :method => :put, :class => "edit_post", :id => "edit_post_45" } do |f| %> |
||||
# ... |
||||
# <% end %> |
||||
# |
||||
# === Nested Resource |
||||
# |
||||
# Example: |
||||
# <% remote_form_for([@post, @comment]) do |f| %> |

# ... |

# parameter with the Ajax call. |

# %> |
||||
# |
||||
# Required +options+ are either of: |
||||
# <tt>:url</tt>:: +url_for+-style options for the action to call |
||||
# when the field has changed. |
||||
# <tt>:function</tt>:: Instead of making a remote call to a URL, you |
||||
# can specify javascript code to be called instead. |
||||
# Note that the value of this option is used as the |
||||
# *body* of the javascript function, a function definition |
||||
# with parameters named element and value will be generated for you |
||||
# for example: |
||||
# observe_field("glass", :frequency => 1, :function => "alert('Element changed')") |
||||
# will generate: |
||||
# new Form.Element.Observer('glass', 1, function(element, value) {alert('Element changed')}) |
||||
# The element parameter is the DOM element being observed, and the value is its value at the |
||||
# time the observer is triggered. |
||||
# |
||||
# Additional options are: |
||||
# <tt>:frequency</tt>:: The frequency (in seconds) at which changes to |
||||
# this field will be detected. Not setting this |
||||
# option at all or to a value equal to or less than |
||||
# zero will use event based observation instead of |
||||
# time based observation. |
||||
# <tt>:update</tt>:: Specifies the DOM ID of the element whose |
||||
# innerHTML should be updated with the |
||||
# XMLHttpRequest response text. |
||||
# <tt>:with</tt>:: A JavaScript expression specifying the parameters |
||||
# for the XMLHttpRequest. The default is to send the |
||||
# key and value of the observed field. Any custom |
||||
# expressions should return a valid URL query string. |
||||
# The value of the field is stored in the JavaScript |
||||
# variable +value+. |
||||
# |
||||
# Examples |
||||
# |
||||
# :with => "'my_custom_key=' + value" |
||||
# :with => "'person[name]=' + prompt('New name')" |
||||
# :with => "Form.Element.serialize('other-field')" |
||||
# |
||||
# Finally |
||||
# :with => 'name' |
||||
# is shorthand for |
||||
# :with => "'name=' + value" |
||||
# This essentially just changes the key of the parameter. |
||||
# |
||||
# Additionally, you may specify any of the options documented in the |
||||
# <em>Common options</em> section at the top of this document. |
||||
# |
||||
# Example: |
||||
# |
||||
# # Sends params: {:title => 'Title of the book'} when the book_title input |
||||
# # field is changed. |
||||
# observe_field 'book_title', |
