window.addEventListener("onbeforeunload",function() {return "are you sure?"});

^这似乎不起作用... ...页面将关闭而不显示确认框...

我意识到......

window.onbeforeunload = function() {return "are you sure?"}

会工作,但我想添加功能(例如添加许多事件监听器到"onbeforeunload"功能)不完全重写功能!

当django压缩css时,它会将输出保存到/static/CACHE/css/[filename].css中的文件中,但无论我尝试什么,css文件都会一直空白!

在我的模板中......

{% compress css %}
<link rel='stylesheet' type='text/less' href='{{ STATIC_URL }}css/deals_for_you.less'/>
{% endcompress %}

我成功安装了django_compressor,django_appconf和versiontools我成功安装了lessc(testecd)STATICFILES_FINDERS已设置

COMPRESS_OFFLINE = True
COMPRESS_ENABLED = True
COMPRESS_OFFLINE_CONTEXT = {
    'STATIC_URL': STATIC_URL,
}
COMPRESS_PRECOMPILERS = (
    ('text/less', 'lessc {infile} {outfile}'),
)

还有,当我跑

python manage.py compress

它输出......

Found 'compress' tags in:
    [/my/file/path]/index.html
Compressing... done
Compressed 1 block(s) from 1 template(s)

但是我得到的输出文件(在/static/CACHE/css/d41d8cd98f00.css)总是空的!
