checkbox

问题 I am developing an application that requires the value of multiple checkboxes. I have nested lists containing checkboxes. The current functionality is this: When a parent is checked, all children are checked under it. When a child is checked, the parent is not selected. I need to add this functionality: When a child is unchecked after the parent is checked, the parent unchecks, but leaves the children checked. $('input[name="level-1"],input[name="level-2"]').bind('click', function () { $(

问题 I'm brand new to Javascript and JQuery, so I've been reading up on it and am trying to check (and set inactive) a checkbox in a parent list-item when one of the children are checked. If this doesn't make any sense, take a look at the list structure. <ul> <li><input type="checkbox" name="items[]" value="88712003" id="88712003" /> Parent 1</li> <li><input type="checkbox" name="items[]" value="88712003" id="88712003" /> Parent 2 <ul> <li><input type="checkbox" name="items[]" value="21312341" id=

问题 I am placing markers on a Google map. I have a number of checkboxes (19 currently) in a form that I am trying to create a dynamic "and" condition to display or not display markers. The code works great for the individual pieces when a single checkbox is selected. I would like to have the code take into account if multiple checkboxes are selected and only display those markers that meet all conditions not just add the ones that meet the next condition. Givens: The checkbox ids are "q"+# Each

问题 I have a checkbox whose value $row['uid'] I would like to store in local storage using javascript or jquery. When the user "unchecks" the checkbox, the value should be removed from local storage This is my html: <form> Favorites <input type="checkbox" class="favorite" value="'.$row['uid'].' onclick='.fave.add();'"></form> This is what I have for the local storage in javascript at the moment. I'm not quite sure how I should add and remove the value $row['uid'] var fave = fave || {}; var data =

问题 I've set up a Rails form roughly following the instructions in this Railscast. Here's the code for the form: <% form_tag complete_todos_path, :method => :put do %> <ul> <div id="incomplete_todos"> <% @incomplete_todos.each do |todo| %> <%= render :partial => todo %> <% end %> </div> </ul> <%= submit_tag "Mark as completed" %> <% end %> And here's the code for the todo partial: <div class="todo"> <li> <%= check_box_tag "todo_ids[]", todo.id %> <%=h todo.name %> <%= link_to 'edit', edit_todo

问题 This is the ListBox code: <ListBox x:Name="courseslistview" ItemsSource="{Binding .}" FontSize="18.667" FontFamily="Trebuchet MS" LayoutUpdated="courseslistview_LayoutUpdated"> <ListBox.ItemTemplate> <DataTemplate> <CheckBox Content="{Binding .}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> How can I use C# to get all the checked checkboxes in the above ListBox? 回答1: It would probably be best to bind the CheckBox to the IsSelected property of the ListBoxItem , like so: <DataTemplate>

问题 I made a group of checkboxes with Twitter Bootstrap. Now I would like to do a "select all" or "deselect all" button. How could I do this using a JS function? The Twitter Bootstrap documentation says to use $().button('toggle') but it doesn't work. Here is my code snippet: <div class="control-group"> <div class="controls"> <div class="input"> <div class="btn-group"> <label class="btn btn-toggle" for="colors-1-toggle-0"> <input type="checkbox" id="colors-1-toggle-0" name="colors-1[]" value=
