我目前正在使用Twitter Bootstrap框架,当使用模态窗口时,我无法通过js元素来工作,如datepicker或验证,尽管选择和均匀渲染正确.请看下面的模态窗口:

  <div class="modal hide in" id="newMember" style="display: block; " aria-hidden="false">
        <div class="modal-header">
          <button class="close" data-dismiss="modal" type="button">×</button>
          <h3>New Member Form</h3>
        </div>
        <form accept-charset="UTF-8" action="/players" class="form-horizontal" id="new_user" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="?"><input name="authenticity_token" type="hidden" value="KdL6cc2Vb53qeMY+PpBUS70myT4HX1uWofMUBolLea8="></div>
          <div class="modal-body">
            <div class="widget-content nopadding">
              <div class="control-group">
                <label class="control-label" for="user_role">Role</label>
                <div class="controls">
                  <select id="user_role" name="user[role]" style="display: none; " class="chzn-done"><option value="">Select member role</option>
                  <option value="1">Player</option>
                  <option value="2">Coach</option>
                  <option value="3">Parent</option>
                  <option value="4">Manager</option>
                  <option value="5">Non-player</option></select><div id="user_role_chzn" class="chzn-container chzn-container-single" style="width: 222px; "><a href="javascript:void(0)" class="chzn-single"><span>Select member role</span><div><b></b></div></a><div class="chzn-drop" style="left: -9000px; width: …

我最近从RVM迁移到Rbenv,当我尝试执行rails时,我收到的错误如下所示

Pauls-Air:~ $ rails
rbenv: rails: command not found

The `rails' command exists in these Ruby versions:
  2.1.2

我有一个选择框的代码,由Chosen jQuery插件显示.我想要实现的是从已选择的当前项获取值:

<div>
  <select id="schedule_event" name="schedule[event]" style="display: none; " class="chzn-done"><option value="Game" selected="selected">Game</option>
    <option value="Event">Event</option>
    <option value="Training">Training</option>
  </select>
  <div id="schedule_event_chzn" class="chzn-container chzn-container-single chzn-container-active" style="width: 854px; ">
    <a href="javascript:void(0)" class="chzn-single chzn-single-with-drop" tabindex="-1">
      <span>Game</span>
      <div></div>
    </a>
    <div class="chzn-drop" style="width: 849px; top: 27px; left: 0px; ">
      <div class="chzn-search">
        <input type="text" autocomplete="off" style="width: 814px; " tabindex="0">
    </div>
    <ul class="chzn-results">
      <li id="schedule_event_chzn_o_0" class="active-result result-selected highlighted" style="">Game</li>
      <li id="schedule_event_chzn_o_1" class="active-result" style="">Event</li>
      <li id="schedule_event_chzn_o_2" class="active-result" style="">Training</li>
    </ul>
  </div>
</div>
</div>

我现在用来查找当前值的JavaScript是:

$("#schedule_event").chosen().change( function() {
    alert(+ $(this).text());
    $('#' + …

我正在尝试设计从某些方面的默认值中显示不同的布局模板.

当用户进入登录页面时,我有这个工作,但我需要显示不同的布局,以便注册,忘记密码和重置.

这是我的应用程序控制器中的当前代码:

layout :layout

  private
  def layout
    # only turn it off for login pages:
    is_a?(Devise::SessionsController) ? "login" : "application"
    # or turn layout off for every devise controller:
    #devise_controller? && "application"
  end

当我从轨道表格中保存多个红宝石时,它似乎在前面添加了一个空白元素.我该如何删除它？该字段是selected_player.

{"utf8"=>"?",
 "authenticity_token"=>"H8W7qPBezubyeU0adnTGZ4oJqYErin1QNz5oK0QV6WY=",
 "schedule"=>{"event"=>"1",
 "result_id"=>"",
 "time"=>"26/10/2012",
 "duration"=>"15",
 "arrival_time"=>"14",
 "location_id"=>"25",
 "selected_players"=>["", "38", "41"],
 "team_id"=>"1",
 "opponent_id"=>"7",
 "home_or_away"=>"Home"},
 "commit"=>"Save Event"}

调节器

def update
  @schedule = Schedule.find(params[:id])
  @user = User.find(current_user)
  @players = User.where(:team_id => current_user[:team_id]).all

  respond_to do |format|
    if @schedule.update_attributes(params[:schedule])
      Notifier.event_added(@user,@schedule).deliver
      format.html { redirect_to(@schedule,
                                :notice => "#{event_display_c(@schedule.event)} vs #{@schedule.opponent.name} was successfully updated.") }
      format.json { head :no_content }
    else
      format.html { render :action => "edit" }
      format.json { render :json => @schedule.errors, :status => :unprocessable_entity }
    end
  end
end

我想对某些标准操作进行部分调用.我正在使用此方法来调用partial:

 %li= link_to 'Delete Event', 'javascript:void(0);', :class => 'alert tiny button', :data => {'reveal-id' => :RevealDelete}
= render 'layouts/reveal_delete', :item => event_display(@event.event), :resource => @event

然后在我的部分,

#RevealDelete.reveal-modal


 %a.close-reveal-modal ×
  %h3= "Delete #{item}"
  %p Are you sure you want to delete this?
  =link_to "Delete #{item}", resource, :method => :delete, :remote => :true, :confirm => resource, :class => 'button close-reveal-modal'
  %a.button.alert.close-reveal-modal Cancel

我怎么能有这样的东西:

link_to 'Delete', '#', :partial => 'layouts/delete', :remote => :true? 

所以我只在点击时渲染部分,而不是在页面加载时渲染？

我有一个导航栏,在加载时从页面顶部开始大约200px.当我向下滚动时,我希望导航栏能够"粘贴"到页面的顶部,并在滚动浏览其余内容时可见.我可以让导航栏从顶部保持200px的位置,它忽略了我向前拉的内容并将其全部拉到左侧.我需要确保导航栏仍然可见,并且布局/样式在整个过程中都是相同的.

下面是我的jsfiddle,显示我遇到的麻烦

  <!-- Begin Logo / Search -->
  <header class="masthead">
      <div class="row">
        <div class="span6">
          <div class="logo pull-left">

我试图使用内联if语句来检查是否存在一个数据,以及是否显示它.此代码当前位于我的渲染,返回块中.

我遇到的问题是使用它,内容不再呈现

{(() => {
              if (this.props.data.size) {
                <Text style={styles.headerLabel}>Sizes</Text>
                {(this.props.data.size||[]).map((section,i) => (
                  <AddToCartRow key={i} data={section} productName={this.props.data.name} value={Config.priceToPriceWithCurrency(section.price)} />
                ))}
              }
            })()}

我正在尝试找出如何用竖线（|）分隔限制器值的方法

<div class="field limiter">
    <label class="label" for="limiter">
        <span><?= /* @escapeNotVerified */ __('View:') ?></span>
    </label>
    <div class="control">
        <?php foreach ($block->getAvailableLimit() as $_key => $_limit): ?>
            <a data-role="limiter" href="#" data-value="<?php /* @escapeNotVerified */ echo $_key ?>"<?php if ($block->isLimitCurrent($_key)): ?>
                class="selected"<?php endif ?>>
                <?php /* @escapeNotVerified */ echo $_limit ?>
            </a>
        <?php endforeach; ?>
    </div>
</div>
