我一直在寻找关于如何创建一个进度条，通知用户他们已完成多少工作的互联网。我了解如下Bootstrap's website.上显示的HTML部分然而，我不明白我应该如何使用JavaScript中检索到的用户数据（来自view code api（表示采用的和剩余的类））来显示用户进度的进度条。实现引导进度条来通知用户课程进度
任何帮助/解释（什么是你的思考过程？有没有什么好的教程？）这个noob非常赞赏！我仍然想学习最好的实践和表现。谢谢！
我在看Stacks问题有user input改变进度条（不太正确），time incrementation，另一个使用checkboxes改变进度条（焦点是JS代码在这里）。
目前正在使用：Python 2.7版，金字塔（Web框架），自举/ Jinja2的模板
查看代码：
@view_config(route_name='assessments', request_method='GET', renderer='templates/unique_assessments.jinja2', permission='create')
def view_unique_microseries_group(request):
logged_in_userid = authenticated_userid(request)
if logged_in_userid is None:
raise HTTPForbidden()
all_assessments = api.retrieve_assessments() #all assessments in a list
#url = HTTPSeeOther(location=request.route_url('microseries'))
return {'logged_in': logged_in_userid, 'all_assessments': all_assessments}
@view_config(route_name='microseries', request_method='GET', renderer='templates/assessments.jinja2', permission='create')
def view_microseries_subseries(request):
logged_in_userid = authenticated_userid(request) #Authenticated User
if logged_in_userid is None:
raise HTTPForbidden()
microseries = int(request.matchdict['id']) #grabs class no. from link in assessments
microseries_list = api.retrieve_assessment(microseries=microseries)
#print 'microseries_list', microseries_list #prints all the matching number of microseries
all_assessments = api.retrieve_assessments() #all assessments in a list
user_results = api.retrieve_assessment_results() #all user results in a list
completed_assessments = []
pending_assessments = []
for assessment in all_assessments:
if assessment is None: # assumes None
continue
found_assessment_result = False
for result in user_results:
if result.owner.username == logged_in_userid and result.assessment == assessment:
found_assessment_result = True # assign Boolean statement
break # no need to check further
if found_assessment_result:
completed_assessments.append(assessment)
else:
pending_assessments.append(assessment)
message = 'Completed'
return {'completed_assessments': completed_assessments, 'pending_assessments': pending_assessments, 'logged_in': logged_in_userid, 'message': message, 'all_assessments':all_assessments, 'microseries_list': microseries_list}
