示例1: labjs
# 需要导入模块: from django.template import NodeList [as 别名]
# 或者: from django.template.NodeList import extend [as 别名]
def labjs(parser, token):
"""
Renders a labjs queue from linked js.
Syntax::
{% labjs %}
<html of linked JS>
{% endlabjs %}
Examples::
{% labjs %}
<script
type="text/javascript"
src="{{ STATIC_URL }}js/jquery-1.5.2.min.js">
</script>
{% wait %}
<script
type="text/javascript"
src="{{ STATIC_URL }}js/jquery.formset.min.js">
</script>
<script
type="text/javascript"
src="{% url django.views.i18n.javascript_catalog %}">
</script>
{% endlabjs %}
Which would be rendered something like::
<script type="text/javascript">
$LAB.queueScript("/static/js/jquery-1.5.2.min.js")
.queueScript("/static/js/jquery.formset.min.js")
.queueScript("/jsi18n/");
</script>
