##如果需要传参或者需要做按钮事件可去相应的JS页面进行按钮绑定事件。

<div class="panel panel-default panel-intro">
    {:build_heading()}

    <div class="panel-body">
        <div id="myTabContent" class="tab-content">
            <div class="tab-pane fade active in" id="one">
                <div class="widget-body no-padding">
                    <div id="toolbar" class="toolbar">
