Django:django后台传递数据到js中

#奇怪传递字典时前台接收不到？？？
datalist= [{'site': '自强学堂', 'author': '涂伟忠'}]
#只要列表能接收
# datalist=[[93, 93, 0, 100.01], [20, 23, 26, 29]]
dl=json.dumps(datalist)
return render(request, 'showcase/bootstrapTable.html', {'datalist': dl})

<script>
  var aaa = JSON.parse('{{ datalist|safe }}');
  alert(aaa);
</script>
