django登陆成功失败，显示颜色

登录成功显示绿色，失败显示红色

在上一节基础上:

样式中加入:

.greenspan{color:green}

.redspan{color:red}

最后加一个result变量，后面加上safe

Result后面加safe

{{result|safe}}

对于单个变量，可以在其后面加上safe过滤器，告诉Django这个字符串不用进行HTML转义

加上一个简单的登陆函数

def userLogin(uname,upass):

if uname == "shenyi" and upass == "123":

return True

else:

return False

def hi(request):

beijin = {"id":1,"dd":"北京"}

shanghai = {"id":2,"dd":"上海"}

userAreas = [beijin,shanghai]

dataset = {‘result‘:‘必须输入数字‘,"areas":userAreas}

if userLogin(request.POST.get("txtUserName"),request.POST.get("txtUserPass")):

dataset[‘result‘] = ‘<span class="greenspan">登录成功</span>‘

else:

dataset[‘result‘] = ‘<span class="redspan">登陆失败</span>‘

return render_to_response("index.html",dataset)

request.POST.get("txtUserName")

request.POST.get("txtUserPass")

分别得到输入框中用户名和密码的值
