symfony - 如何使用条件 if 进入 assetic

Question

我有一个 html 模板，并且有一个条件为 --> 的代码

<!--[if !IE]> -->

    <script type="text/javascript">
        window.jQuery || document.write("<script src='assets/js/jquery-2.0.3.min.js'>"+"<"+"/script>");
    </script>

    <!-- <![endif]-->

    <!--[if IE]>
   <script type="text/javascript">
        window.jQuery || document.write("<script src='assets/js/jquery-1.10.2.min.js'>"+"<"+"/script>");
   </script>
   <![endif]-->

我想知道如何在该 assetic 中使用此if

{% block Javascript %}
    {% javascripts output='js/dashboard/main.js' filter='?yui_js'
    'dashboard/js/date-time/bootstrap-datepicker.min.js'
    %}
    <script type="text/javascript" src="{{ asset_url }}"></script>
    {% endjavascripts %}
{% endblock %}

Answer 1

如果您只想使用这个if，您可以将此代码放入 block 中:

{% block Javascript %}
    <!--[if !IE]> -->

    <script type="text/javascript">
        window.jQuery || document.write("<script src='assets/js/jquery-2.0.3.min.js'>"+"<"+"/script>");
    </script>

    <!-- <![endif]-->

    <!--[if IE]>
   <script type="text/javascript">
        window.jQuery || document.write("<script src='assets/js/jquery-1.10.2.min.js'>"+"<"+"/script>");
   </script>
   <![endif]-->
    {% javascripts output='js/dashboard/main.js' filter='?yui_js'
    'dashboard/js/date-time/bootstrap-datepicker.min.js'
    %}
    <script type="text/javascript" src="{{ asset_url }}"></script>
    {% endjavascripts %}
{% endblock %}

如果您想将 jquery.min.js 与其他脚本一起编译到一个文件中，您需要类似的东西:

{% block Javascript %}
    <!--[if !IE]> -->
    {% javascripts output='js/dashboard/main.js' filter='?yui_js'
    'dashboard/js/date-time/bootstrap-datepicker.min.js'
    'assets/js/jquery-2.0.3.min.js'
    %}
    <script type="text/javascript">
        window.jQuery || document.write("<script src='{{ asset_url }}'>"+"<"+"/script>");
    </script>
    {% endjavascripts %}

    <!-- <![endif]-->

    <!--[if IE]>
    {% javascripts output='js/dashboard/main-ie.js' filter='?yui_js'
    'dashboard/js/date-time/bootstrap-datepicker.min.js'
    'assets/js/jquery-1.10.2.min.js'
    %}
    <script type="text/javascript">
        window.jQuery || document.write("<script src='{{ asset_url }}'>"+"<"+"/script>");
    </script>
    {% endjavascripts %}
   <![endif]-->

{% endblock %}
