我让用户做一个测试。在每个问题之后,我想让他们看看他们的答案是正确的还是错误的。正确的答案应该以绿色突出显示,他们的答案(如果不正确)应该以红色突出显示(使用Twitter引导样式)。你知道吗
我目前正在用Django和HTML呈现测验结果页面,如下所示:
{{ player.question }}
<div class="myradio">
<label for="choice_1"><input id="id_1" type="radio" value="q1" disabled /> {{q1}}</label>
</div>
<div class="myradio">
<label for="choice_2"><input id="id_2" type="radio" value="q2" disabled /> {{q2}}</label>
</div>
<div class="myradio">
<label for="choice_3"><input id="id_3" type="radio" value="q3" disabled /> {{q3}}</label>
</div>
<div class="myradio">
<label for="choice_4"><input id="id_4" type="radio" value="q4" disabled /> {{q4}}</label>
</div>
<p><b>Correct Answer: {{solution}}<b></p>
Total Score: {{total_score}}
我把问题的答案存储在{{solution}}
。我一直在尝试找出如何有选择地应用CSS过滤器,例如,如果{{q1}} == {{solution}}
应该高亮显示为绿色。我可以用{{player.submitted_answer}}
获取参与者的答案,因此我想突出显示div元素red if{{player.submitted_answer}} != {{solution}}
。你知道吗
我试过摆弄if语句块,但似乎做不好。有什么想法吗?你知道吗
@cezar,一段页码.py以及型号.py你知道吗
在页码.py我有以下课程
class Question(Page):
timeout_seconds = 120
template_name = 'quiz/Question.html'
form_model = 'player'
form_fields = ['submitted_answer', 'confidence']
def submitted_answer_choices(self):
qd = self.player.current_question()
return [
qd['choice1'],
qd['choice2'],
qd['choice3'],
qd['choice4'],
]
def confidence_error_message(self, value):
if value == 50:
return 'Please indicate your confidence in your answer. It is important you answer accurately.'
def before_next_page(self):
self.player.check_correct()
在型号.py,相关类为Player和Subsession:
class Player(BasePlayer):
trial_counter = models.IntegerField(initial=0)
question_id = models.IntegerField()
confidence = models.FloatField(widget=widgets.Slider(attrs={'step': '0.01'}))
confidence_private = models.FloatField(widget=widgets.Slider(attrs={'step': '0.01'}))
question = models.StringField()
solution = models.StringField()
submitted_answer = models.StringField(widget=widgets.RadioSelect)
submitted_answer_private = models.StringField(widget=widgets.RadioSelect)
is_correct = models.BooleanField()
total_score = models.IntegerField(initial = 0)
def other_player(self):
return self.get_others_in_group()[0]
def current_question(self):
return self.session.vars['questions'][self.round_number - 1]
def check_correct(self):
self.is_correct = self.submitted_answer == self.solution
def check_partner_correspondence(self):
self.submitted_answer == self.get_others_in_group()[0].submitted_answer
def check_partner_correct(self):
self.get_others_in_group()[0].submitted_answer == self.solution
def check_if_awarded_points(self):
self.get_others_in_group()[0].submitted_answer == self.submitted_answer == self.solution
def score_points(self):
if self.get_others_in_group()[0].submitted_answer == self.submitted_answer == self.solution:
self.total_score +=1
else:
self.total_score -=1
def set_payoff(self):
if(self.check_if_awarded_points()):
self.total_score +=1
class Subsession(BaseSubsession):
def creating_session(self):
if self.round_number == 1:
self.session.vars['questions'] = Constants.questions
## ALTERNATIVE DESIGN:
## to randomize the order of the questions, you could instead do:
# import random
# randomized_questions = random.sample(Constants.questions, len(Constants.questions))
# self.session.vars['questions'] = randomized_questions
## and to randomize differently for each participant, you could use
## the random.sample technique, but assign into participant.vars
## instead of session.vars.
for p in self.get_players():
question_data = p.current_question()
p.question_id = question_data['id']
p.question = question_data['question']
p.solution = question_data['solution']
我最终解决了自己的问题:
我不知道该怎么办,因为阿尔巴的回答帮助最大。你知道吗
然后是CSS:
你可以用一些CSS和最小的模板来实现这一点。你知道吗
考虑下面的HTML模板
这里的关键是
class="answer{% if answer == solution %} solution{% endif %}"
使用以下CSS
接下来的路线
你会得到一个类似this jsfiddle的结果
我同意@Sapna Sharma和@albar的评论。你知道吗
您可以使用一个简单的CSS类将颜色设置为绿色,并使用
{% if [...] %}
模板过滤器将CSS类仅添加到正确答案中您可以参考Django official documentation来了解如何处理模板过滤器。你知道吗
