devise_mapping.registerable?,devise_mapping.recoverable?来自哪里?(where do devise_mapping.registerable?, devise_mapping.recoverable?…come from?)
devise_mapping.registerable?
在哪里devise_mapping.registerable?
,devise_mapping.recoverable?
....来自? 我的意思是我找不到他们被指示的文件,他们找不到任何关于他们的文件。为什么if..end结构中始终存在“ - ”? 例如:
<%- if controller_name != 'sessions' %> <%= link_to "Sign in", new_session_path(resource_name) %><br /> <% end -%>
where do
devise_mapping.registerable?
,devise_mapping.recoverable?
....come from? I mean I can't find a file where they are indicated, can find nothing about them.And why is there always a "-" in the if..end structures? For instance:
<%- if controller_name != 'sessions' %> <%= link_to "Sign in", new_session_path(resource_name) %><br /> <% end -%>

最满意答案
您可以根据
checked
复选框创建一个有效的选择器//Hide All elements $('.single').hide(); //Get checked checkboxes var checkedCheckboxes = $('input[name="short"],input[name="weekly"],input[name="small"],input[name="medium"],input[name="big"]').filter(':checked'); //If User has selected any checkbox if (checkedCheckboxes.length) { //Get name var names = checkedCheckboxes.map(function () { return $(this).attr('name'); }).get(); //Create selector var selector = '.' + names.join('.'); //Show target elements $('.single' + selector).show(); }
You can create a valid selector based on
checked
checkboxes//Hide All elements $('.single').hide(); //Get checked checkboxes var checkedCheckboxes = $('input[name="short"],input[name="weekly"],input[name="small"],input[name="medium"],input[name="big"]').filter(':checked'); //If User has selected any checkbox if (checkedCheckboxes.length) { //Get name var names = checkedCheckboxes.map(function () { return $(this).attr('name'); }).get(); //Create selector var selector = '.' + names.join('.'); //Show target elements $('.single' + selector).show(); }
