title: Bootstrap tabs refreshing page
body: <p>I'm just trying to implement basic bootstrap tab functionality, but whenever I click on a tab the page refreshes instead of just show/hide the appropriate content. What is causing this issue?</p>
  
  <pre><code>&lt;ul id="myTab" class="nav nav-tabs" role="tablist"&gt;
              &lt;li class="active"&gt;&lt;a href="#forcast" role="tab" data-toggle="tab"&gt;Forecast&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#month" role="tab" data-toggle="tab"&gt;By Month&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#ytd" role="tab" data-toggle="tab"&gt;YTD&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#age" role="tab" data-toggle="tab"&gt;By Age&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#overdue" role="tab" data-toggle="tab"&gt;Months Overdue&lt;/a&gt;&lt;/li&gt;
              &lt;li class="pull-right secondary-nav"&gt;&lt;button class="btn btn-default btn-xs" ng-click="collapsedkpi=!collapsedkpi"&gt;&lt;i class="glyphicon glyphicon-filter"&gt;&lt;/i&gt; Filters&lt;/button&gt;&lt;/li&gt;
          &lt;/ul&gt;
          &lt;div class="tab-content"&gt;
          &lt;div class="tab-pane active" id="forcast"&gt;
              &lt;div id="chartdiv"&gt;&lt;/div&gt;
          &lt;/div&gt;
          &lt;div class="tab-pane" id="month"&gt;
              Hello Month
          &lt;/div&gt;
          &lt;div class="tab-pane" id="ytd"&gt;
              Hello YTD
          &lt;/div&gt;
          &lt;div class="tab-pane" id="age"&gt;
              Hello Age
          &lt;/div&gt;
          &lt;div class="tab-pane" id="overdue"&gt;
              Hello Overdue
          &lt;/div&gt;
          &lt;/div&gt;
