[英]Javascript rendering in tornado webserver
In following code snippet I'm trying to add JavaScript Files from Tornado server in HTML file in <HEAD>
tag. 在以下代码段中,我试图在
<HEAD>
标记的HTML文件中从Tornado服务器添加JavaScript文件。
DEBUG_SCRIPTS = ''' <script src="src/main.js" type="text/javascript"></script> '''
class Entries(tornado.web.UIModule):
def javascript_files(self):
return 'src/main.js'
class MainHandler(tornado.web.RequestHandler):
def get(self):
params = {}
params['CORE_SCRIPTS'] = DEBUG_SCRIPTS
path = os.path.join(os.path.dirname(__file__), 'index.html')
self.render(path, params=params)
by params['CORE_SCRIPTS'] = DEBUG_SCRIPTS
I was trying to add the <script>
tag in HTML but it gets parsed in text which generates 通过
params['CORE_SCRIPTS'] = DEBUG_SCRIPTS
我试图在HTML中添加<script>
标记,但是它被解析为文本,从而生成
<script type="text/javascript" src="src/main.js"></script>
So I came across javascript_files()
method in tornado specs but I'm not getting any examples about its implementations. 因此,我在龙卷风规范中遇到了
javascript_files()
方法,但没有得到有关其实现的任何示例。 Can anyone help? 有人可以帮忙吗?
javascript files
only works with UIModules . javascript files
仅适用于UIModules 。 Javascript files included that way are appended to the page just before the end of the body tag, though, not in the head tag. 但是,以这种方式包含的Javascript文件会在body标签末尾之前添加到页面中,而不是在head标签中。
If you really want the file included in the head tag, you can simply output the value of params['CORE_SCRIPTS']
in the head tag of your template: 如果您确实希望文件包含在head标签中,则只需在模板的head标签中输出
params['CORE_SCRIPTS']
的值即可:
{% raw params['CORE_SCRIPTS'] %}
