全选/取消全选页面中的复选框

Question

I've looked at this which seems to have no effect on my code. I've tried this which seems to only affect the first checkbox, but doesn't uncheck the checkbox when i click it again anyway.... I've also seen some other ways of doing it that I'm not certain are entirely Rails-esque (or whatever the term should be).

So, could someone please point me in the right direction?

Here is my view:

<%= render 'admin/distributions/head' %>
<% title 'Workflow' %>


<%= form_for @search, :url => url_for(:controller => params[:controller], :action => params[:action]), :html => {id => "distribution_workflow",:method => :get} do |f| %>

  <div class="opportunity-block yellow">

    <div class="form-block mrl mbm">
      <%= f.label :created_at_gt, "Created at >" %>
      <%= f.text_field :created_at_gt, :class => "js-db-date-picker" %>
    </div>

    <div class="form-block mrl mbm">
      <%= f.label :created_at_lte, "Created at <=" %>
      <%= f.text_field :created_at_lte, :class => "js-db-date-picker" %>
    </div>

    <div class="form-block mrl mbm mtm">
      <%= f.label :status_equal, "Status" %>
      <%= f.select :status_equal, %w(delivered no_success already_registered qa_complete success follow_up), :include_blank => " " %>
    </div>

    <div class="clear"></div>
    <%= submit_tag 'Apply Filter', :class => "input-button dark unit-right mrl" %>
    <div class="clear"></div>
  </div>
<% end  %>


<%= form_tag edit_multiple_admin_distributions_workflows_path , :id => "workflow_form" do %>
<%= submit_tag "Edit Selected" %>
  <table class="standard-grid"> 
    <tr> 
      <th class="first"> </th>
      <th>ID</th>
      <th>Customer</th>
      <th>Resume URL</th>
      <th>Partner</th>
      <th>Status</th>
      <th>Assigned To</th>
      <th>Comments</th>
    </tr>
    <% @report.each do |distribution| %>
      <tr>
        <td><%= check_box_tag "distribution_ids[]", distribution.id %></td>
        <td>
          <%= distribution.owner.id %>
        </td>
        <td>
          <%=link_to distribution.owner.full_name, "mailto:#{distribution.owner.email}" %>
        </td>
        <td>
          <a href=<% UrlService.download_blob_url(distribution.resume) %>>Resume URL</a>
        </td>
        <td>
          <%=link_to distribution.matching_profile.partner.title,  "mailto:#{distribution.matching_profile.partner.email}" %>
        </td>
        <td>
          <%= distribution.status %>
        </td>
        <td>
          <%= distribution.assignee_id ? User.find(distribution.assignee_id).full_name : " " %>
        </td>
        <td>
          <%= distribution.comments %>
        </td>
      </tr>
    <% end %>
  </table>
<% end %>

Answer 1

Here's a working example for you: http://jsfiddle.net/wYPWL/

HTML example:

<input type="checkbox" id="selectAll" value="selectAll"> Select / Deselect All<br/><br/>

<input type="checkbox" name="foo" value="bar1"> Bar 1<br/>
<input type="checkbox" name="foo" value="bar2"> Bar 2<br/>
<input type="checkbox" name="foo" value="bar3"> Bar 3<br/>
<input type="checkbox" name="foo" value="bar4"> Bar 4<br/>

Javascript:

$('#selectAll').click(function() {
   if (this.checked) {
       $(':checkbox').each(function() {
           this.checked = true;                        
       });
   } else {
      $(':checkbox').each(function() {
           this.checked = false;                        
       });
   } 
});

This will work regardless of what your checkboxes are named. If you really wanted to target only your checkboxes shown in your code above, you can replace $(':checkbox') with $('input[id^="distribution_ids"]') which is jQuery's way of targeting input elements that have an ID that starts with distribution_ids

Answer 2

If using jquery, you can use the following (coffeeScript):

if (this.checked)
  $(':checkbox').each ->
    $(this).prop('checked', true)                     
else
  $(':checkbox').each ->
    $(this).prop('checked', false)

I found an issue trying to set this.checked = false - not really sure what was happening, but the above code worked.

I have found an issue with iWasRobbed 's Answer that if Select All is checked and then if you unchecked any one option like ( Bar1 , Bar2 , Bar3 ) then Select All must be unchecked...

Here is Solution..

HTML Code

<input id="campaign_range_ids_1" class="checkbox" type="checkbox" value="1" name="campaign[range_ids][]"> India
<input id="campaign_range_ids_2" class="checkbox" type="checkbox" value="2" name="campaign[range_ids][]"> London
<input id="campaign_range_ids_3" class="checkbox" type="checkbox" value="3" name="campaign[range_ids][]"> USA
<input id="campaign_range_ids_4" class="checkbox" type="checkbox" value="4" name="campaign[range_ids][]"> All

JavaScript Code:

$('#campaign_range_ids_4').click(function () {

    if ($(this).is(':checked')) {
        $('#campaign_range_ids_1,#campaign_range_ids_2,#campaign_range_ids_3').prop('checked', true);

    } else {
        $('#campaign_range_ids_1,#campaign_range_ids_2,#campaign_range_ids_3').prop('checked', false);
    }

});

$('#campaign_range_ids_1,#campaign_range_ids_2,#campaign_range_ids_3').click(function () {

    if ($(this).is(':checked')) {
        } else {
            $('#campaign_range_ids_4').prop('checked', false);
    }

});

Working Demo

Answer 4

In case you want to select-all for multiple separate lists on the same page

$("input[data-select-all]").on("click", function() {
    let $checkboxes = $("input[data-"+$(this).data("select-all")+"]");
    if (this.checked) {
        $checkboxes.each(function() {
            this.checked = true;
        });
    } else {
        $checkboxes.each(function() {
            this.checked = false;
        });
    }
});


<table>
  <thead>
  <tr>
    <th><input type="checkbox" name="selected" id="select-all" value="1" title="Select all" data-select-all="select-all-target"></th>
    <th>Asset</th>
    <th>Description</th>
  </tr>
  </thead>
  <tbody>
    <tr>
    <td><span class="form-check"><input type="checkbox" name="selected" id="asset_type_11" value="1" data-select-all-target="true"></span></td>
    <td>The name</td>
    <td>The description</td>
    </tr>
  </tbody>
</table>
